It is only of interest for Digital TV - device driver writers. The header file for this API is named - demux.h and located in - drivers/media/dvb-core. - - The demux API should be implemented for each demux in the - system. It is used to select the TS source of a demux and to manage - the demux resources. When the demux client allocates a resource via - the demux API, it receives a pointer to the API of that - resource. - Each demux receives its TS input from a DVB front-end or from - memory, as set via this demux API. In a system with more than one - front-end, the API can be used to select one of the DVB front-ends - as a TS source for a demux, unless this is fixed in the HW platform. - The demux API only controls front-ends regarding to their connections - with demuxes; the APIs used to set the other front-end parameters, - such as tuning, are not defined in this document. - The functions that implement the abstract interface demux should - be defined static or module private and registered to the Demux - core for external access. It is not necessary to implement every - function in the struct dmx_demux. For example, - a demux interface might support Section filtering, but not PES - filtering. The API client is expected to check the value of any - function pointer before calling the function: the value of NULL means - that the “function is not available”. - Whenever the functions of the demux API modify shared data, - the possibilities of lost update and race condition problems should - be addressed, e.g. by protecting parts of code with mutexes. - Note that functions called from a bottom half context must not - sleep. Even a simple memory allocation without using GFP_ATOMIC can - result in a kernel thread being put to sleep if swapping is needed. - For example, the Linux kernel calls the functions of a network device - interface from a bottom half context. Thus, if a demux API function - is called from network device code, the function must not sleep. - - - -
- Demux Callback API - This kernel-space API comprises the callback functions that - deliver filtered data to the demux client. Unlike the other DVB - kABIs, these functions are provided by the client and called from - the demux code. - The function pointers of this abstract interface are not - packed into a structure as in the other demux APIs, because the - callback functions are registered and used independent of each - other.

Introduction

+ +

+Read-copy update (RCU) is a synchronization mechanism that is often +used as a replacement for reader-writer locking. +RCU is unusual in that updaters do not block readers, +which means that RCU's read-side primitives can be exceedingly fast +and scalable. +In addition, updaters can make useful forward progress concurrently +with readers. +However, all this concurrency between RCU readers and updaters does raise +the question of exactly what RCU readers are doing, which in turn +raises the question of exactly what RCU's requirements are. + +

+This document therefore summarizes RCU's requirements, and can be thought +of as an informal, high-level specification for RCU. +It is important to understand that RCU's specification is primarily +empirical in nature; +in fact, I learned about many of these requirements the hard way. +This situation might cause some consternation, however, not only +has this learning process been a lot of fun, but it has also been +a great privilege to work with so many people willing to apply +technologies in interesting new ways. + +

+All that aside, here are the categories of currently known RCU requirements: +

+ +
    +
  1. + Fundamental Requirements +
  2. Fundamental Non-Requirements +
  3. + Parallelism Facts of Life +
  4. + Quality-of-Implementation Requirements +
  5. + Linux Kernel Complications +
  6. + Software-Engineering Requirements +
  7. + Other RCU Flavors +
  8. + Possible Future Changes +
+ +

+This is followed by a summary, +which is in turn followed by the inevitable +answers to the quick quizzes. + +

Fundamental Requirements

+ +

+RCU's fundamental requirements are the closest thing RCU has to hard +mathematical requirements. +These are: + +

    +
  1. + Grace-Period Guarantee +
  2. + Publish-Subscribe Guarantee +
  3. + Memory-Barrier Guarantees +
  4. + RCU Primitives Guaranteed to Execute Unconditionally +
  5. + Guaranteed Read-to-Write Upgrade +
+ +

Grace-Period Guarantee

+ +

+RCU's grace-period guarantee is unusual in being premeditated: +Jack Slingwine and I had this guarantee firmly in mind when we started +work on RCU (then called “rclock”) in the early 1990s. +That said, the past two decades of experience with RCU have produced +a much more detailed understanding of this guarantee. + +

+RCU's grace-period guarantee allows updaters to wait for the completion +of all pre-existing RCU read-side critical sections. +An RCU read-side critical section +begins with the marker rcu_read_lock() and ends with +the marker rcu_read_unlock(). +These markers may be nested, and RCU treats a nested set as one +big RCU read-side critical section. +Production-quality implementations of rcu_read_lock() and +rcu_read_unlock() are extremely lightweight, and in +fact have exactly zero overhead in Linux kernels built for production +use with CONFIG_PREEMPT=n. + +

+This guarantee allows ordering to be enforced with extremely low +overhead to readers, for example: + +

+
+ 1 int x, y;
+ 2
+ 3 void thread0(void)
+ 4 {
+ 5   rcu_read_lock();
+ 6   r1 = READ_ONCE(x);
+ 7   r2 = READ_ONCE(y);
+ 8   rcu_read_unlock();
+ 9 }
+10
+11 void thread1(void)
+12 {
+13   WRITE_ONCE(x, 1);
+14   synchronize_rcu();
+15   WRITE_ONCE(y, 1);
+16 }
+
+
+ +

+Because the synchronize_rcu() on line 14 waits for +all pre-existing readers, any instance of thread0() that +loads a value of zero from x must complete before +thread1() stores to y, so that instance must +also load a value of zero from y. +Similarly, any instance of thread0() that loads a value of +one from y must have started after the +synchronize_rcu() started, and must therefore also load +a value of one from x. +Therefore, the outcome: +

+
+(r1 == 0 && r2 == 1)
+
+
+cannot happen. + +

Quick Quiz 1: +Wait a minute! +You said that updaters can make useful forward progress concurrently +with readers, but pre-existing readers will block +synchronize_rcu()!!! +Just who are you trying to fool??? +
Answer + +

+This scenario resembles one of the first uses of RCU in +DYNIX/ptx, +which managed a distributed lock manager's transition into +a state suitable for handling recovery from node failure, +more or less as follows: + +

+
+ 1 #define STATE_NORMAL        0
+ 2 #define STATE_WANT_RECOVERY 1
+ 3 #define STATE_RECOVERING    2
+ 4 #define STATE_WANT_NORMAL   3
+ 5
+ 6 int state = STATE_NORMAL;
+ 7
+ 8 void do_something_dlm(void)
+ 9 {
+10   int state_snap;
+11
+12   rcu_read_lock();
+13   state_snap = READ_ONCE(state);
+14   if (state_snap == STATE_NORMAL)
+15     do_something();
+16   else
+17     do_something_carefully();
+18   rcu_read_unlock();
+19 }
+20
+21 void start_recovery(void)
+22 {
+23   WRITE_ONCE(state, STATE_WANT_RECOVERY);
+24   synchronize_rcu();
+25   WRITE_ONCE(state, STATE_RECOVERING);
+26   recovery();
+27   WRITE_ONCE(state, STATE_WANT_NORMAL);
+28   synchronize_rcu();
+29   WRITE_ONCE(state, STATE_NORMAL);
+30 }
+
+
+ +

+The RCU read-side critical section in do_something_dlm() +works with the synchronize_rcu() in start_recovery() +to guarantee that do_something() never runs concurrently +with recovery(), but with little or no synchronization +overhead in do_something_dlm(). + +

Quick Quiz 2: +Why is the synchronize_rcu() on line 28 needed? +
Answer + +

+In order to avoid fatal problems such as deadlocks, +an RCU read-side critical section must not contain calls to +synchronize_rcu(). +Similarly, an RCU read-side critical section must not +contain anything that waits, directly or indirectly, on completion of +an invocation of synchronize_rcu(). + +

+Although RCU's grace-period guarantee is useful in and of itself, with +quite a few use cases, +it would be good to be able to use RCU to coordinate read-side +access to linked data structures. +For this, the grace-period guarantee is not sufficient, as can +be seen in function add_gp_buggy() below. +We will look at the reader's code later, but in the meantime, just think of +the reader as locklessly picking up the gp pointer, +and, if the value loaded is non-NULL, locklessly accessing the +->a and ->b fields. + +

+
+ 1 bool add_gp_buggy(int a, int b)
+ 2 {
+ 3   p = kmalloc(sizeof(*p), GFP_KERNEL);
+ 4   if (!p)
+ 5     return -ENOMEM;
+ 6   spin_lock(&gp_lock);
+ 7   if (rcu_access_pointer(gp)) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   p->a = a;
+12   p->b = a;
+13   gp = p; /* ORDERING BUG */
+14   spin_unlock(&gp_lock);
+15   return true;
+16 }
+
+
+ +

+The problem is that both the compiler and weakly ordered CPUs are within +their rights to reorder this code as follows: + +

+
+ 1 bool add_gp_buggy_optimized(int a, int b)
+ 2 {
+ 3   p = kmalloc(sizeof(*p), GFP_KERNEL);
+ 4   if (!p)
+ 5     return -ENOMEM;
+ 6   spin_lock(&gp_lock);
+ 7   if (rcu_access_pointer(gp)) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   gp = p; /* ORDERING BUG */
+12   p->a = a;
+13   p->b = a;
+14   spin_unlock(&gp_lock);
+15   return true;
+16 }
+
+
+ +

+If an RCU reader fetches gp just after +add_gp_buggy_optimized executes line 11, +it will see garbage in the ->a and ->b +fields. +And this is but one of many ways in which compiler and hardware optimizations +could cause trouble. +Therefore, we clearly need some way to prevent the compiler and the CPU from +reordering in this manner, which brings us to the publish-subscribe +guarantee discussed in the next section. + +

Publish/Subscribe Guarantee

+ +

+RCU's publish-subscribe guarantee allows data to be inserted +into a linked data structure without disrupting RCU readers. +The updater uses rcu_assign_pointer() to insert the +new data, and readers use rcu_dereference() to +access data, whether new or old. +The following shows an example of insertion: + +

+
+ 1 bool add_gp(int a, int b)
+ 2 {
+ 3   p = kmalloc(sizeof(*p), GFP_KERNEL);
+ 4   if (!p)
+ 5     return -ENOMEM;
+ 6   spin_lock(&gp_lock);
+ 7   if (rcu_access_pointer(gp)) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   p->a = a;
+12   p->b = a;
+13   rcu_assign_pointer(gp, p);
+14   spin_unlock(&gp_lock);
+15   return true;
+16 }
+
+
+ +

+The rcu_assign_pointer() on line 13 is conceptually +equivalent to a simple assignment statement, but also guarantees +that its assignment will +happen after the two assignments in lines 11 and 12, +similar to the C11 memory_order_release store operation. +It also prevents any number of “interesting” compiler +optimizations, for example, the use of gp as a scratch +location immediately preceding the assignment. + +

Quick Quiz 3: +But rcu_assign_pointer() does nothing to prevent the +two assignments to p->a and p->b +from being reordered. +Can't that also cause problems? +
Answer + +

+It is tempting to assume that the reader need not do anything special +to control its accesses to the RCU-protected data, +as shown in do_something_gp_buggy() below: + +

+
+ 1 bool do_something_gp_buggy(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   p = gp;  /* OPTIMIZATIONS GALORE!!! */
+ 5   if (p) {
+ 6     do_something(p->a, p->b);
+ 7     rcu_read_unlock();
+ 8     return true;
+ 9   }
+10   rcu_read_unlock();
+11   return false;
+12 }
+
+
+ +

+However, this temptation must be resisted because there are a +surprisingly large number of ways that the compiler +(to say nothing of +DEC Alpha CPUs) +can trip this code up. +For but one example, if the compiler were short of registers, it +might choose to refetch from gp rather than keeping +a separate copy in p as follows: + +

+
+ 1 bool do_something_gp_buggy_optimized(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   if (gp) { /* OPTIMIZATIONS GALORE!!! */
+ 5     do_something(gp->a, gp->b);
+ 6     rcu_read_unlock();
+ 7     return true;
+ 8   }
+ 9   rcu_read_unlock();
+10   return false;
+11 }
+
+
+ +

+If this function ran concurrently with a series of updates that +replaced the current structure with a new one, +the fetches of gp->a +and gp->b might well come from two different structures, +which could cause serious confusion. +To prevent this (and much else besides), do_something_gp() uses +rcu_dereference() to fetch from gp: + +

+
+ 1 bool do_something_gp(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   p = rcu_dereference(gp);
+ 5   if (p) {
+ 6     do_something(p->a, p->b);
+ 7     rcu_read_unlock();
+ 8     return true;
+ 9   }
+10   rcu_read_unlock();
+11   return false;
+12 }
+
+
+ +

+The rcu_dereference() uses volatile casts and (for DEC Alpha) +memory barriers in the Linux kernel. +Should a +high-quality implementation of C11 memory_order_consume [PDF] +ever appear, then rcu_dereference() could be implemented +as a memory_order_consume load. +Regardless of the exact implementation, a pointer fetched by +rcu_dereference() may not be used outside of the +outermost RCU read-side critical section containing that +rcu_dereference(), unless protection of +the corresponding data element has been passed from RCU to some +other synchronization mechanism, most commonly locking or +reference counting. + +

+In short, updaters use rcu_assign_pointer() and readers +use rcu_dereference(), and these two RCU API elements +work together to ensure that readers have a consistent view of +newly added data elements. + +

+Of course, it is also necessary to remove elements from RCU-protected +data structures, for example, using the following process: + +

    +
  1. Remove the data element from the enclosing structure. +
  2. Wait for all pre-existing RCU read-side critical sections + to complete (because only pre-existing readers can possibly have + a reference to the newly removed data element). +
  3. At this point, only the updater has a reference to the + newly removed data element, so it can safely reclaim + the data element, for example, by passing it to kfree(). +
+ +This process is implemented by remove_gp_synchronous(): + +
+
+ 1 bool remove_gp_synchronous(void)
+ 2 {
+ 3   struct foo *p;
+ 4
+ 5   spin_lock(&gp_lock);
+ 6   p = rcu_access_pointer(gp);
+ 7   if (!p) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   rcu_assign_pointer(gp, NULL);
+12   spin_unlock(&gp_lock);
+13   synchronize_rcu();
+14   kfree(p);
+15   return true;
+16 }
+
+
+ +

+This function is straightforward, with line 13 waiting for a grace +period before line 14 frees the old data element. +This waiting ensures that readers will reach line 7 of +do_something_gp() before the data element referenced by +p is freed. +The rcu_access_pointer() on line 6 is similar to +rcu_dereference(), except that: + +

    +
  1. The value returned by rcu_access_pointer() + cannot be dereferenced. + If you want to access the value pointed to as well as + the pointer itself, use rcu_dereference() + instead of rcu_access_pointer(). +
  2. The call to rcu_access_pointer() need not be + protected. + In contrast, rcu_dereference() must either be + within an RCU read-side critical section or in a code + segment where the pointer cannot change, for example, in + code protected by the corresponding update-side lock. +
+ +

Quick Quiz 4: +Without the rcu_dereference() or the +rcu_access_pointer(), what destructive optimizations +might the compiler make use of? +
Answer + +

+In short, RCU's publish-subscribe guarantee is provided by the combination +of rcu_assign_pointer() and rcu_dereference(). +This guarantee allows data elements to be safely added to RCU-protected +linked data structures without disrupting RCU readers. +This guarantee can be used in combination with the grace-period +guarantee to also allow data elements to be removed from RCU-protected +linked data structures, again without disrupting RCU readers. + +

+This guarantee was only partially premeditated. +DYNIX/ptx used an explicit memory barrier for publication, but had nothing +resembling rcu_dereference() for subscription, nor did it +have anything resembling the smp_read_barrier_depends() +that was later subsumed into rcu_dereference(). +The need for these operations made itself known quite suddenly at a +late-1990s meeting with the DEC Alpha architects, back in the days when +DEC was still a free-standing company. +It took the Alpha architects a good hour to convince me that any sort +of barrier would ever be needed, and it then took me a good two hours +to convince them that their documentation did not make this point clear. +More recent work with the C and C++ standards committees have provided +much education on tricks and traps from the compiler. +In short, compilers were much less tricky in the early 1990s, but in +2015, don't even think about omitting rcu_dereference()! + +

Memory-Barrier Guarantees

+ +

+The previous section's simple linked-data-structure scenario clearly +demonstrates the need for RCU's stringent memory-ordering guarantees on +systems with more than one CPU: + +

    +
  1. Each CPU that has an RCU read-side critical section that + begins before synchronize_rcu() starts is + guaranteed to execute a full memory barrier between the time + that the RCU read-side critical section ends and the time that + synchronize_rcu() returns. + Without this guarantee, a pre-existing RCU read-side critical section + might hold a reference to the newly removed struct foo + after the kfree() on line 14 of + remove_gp_synchronous(). +
  2. Each CPU that has an RCU read-side critical section that ends + after synchronize_rcu() returns is guaranteed + to execute a full memory barrier between the time that + synchronize_rcu() begins and the time that the RCU + read-side critical section begins. + Without this guarantee, a later RCU read-side critical section + running after the kfree() on line 14 of + remove_gp_synchronous() might + later run do_something_gp() and find the + newly deleted struct foo. +
  3. If the task invoking synchronize_rcu() remains + on a given CPU, then that CPU is guaranteed to execute a full + memory barrier sometime during the execution of + synchronize_rcu(). + This guarantee ensures that the kfree() on + line 14 of remove_gp_synchronous() really does + execute after the removal on line 11. +
  4. If the task invoking synchronize_rcu() migrates + among a group of CPUs during that invocation, then each of the + CPUs in that group is guaranteed to execute a full memory barrier + sometime during the execution of synchronize_rcu(). + This guarantee also ensures that the kfree() on + line 14 of remove_gp_synchronous() really does + execute after the removal on + line 11, but also in the case where the thread executing the + synchronize_rcu() migrates in the meantime. +
+ +

Quick Quiz 5: +Given that multiple CPUs can start RCU read-side critical sections +at any time without any ordering whatsoever, how can RCU possibly tell whether +or not a given RCU read-side critical section starts before a +given instance of synchronize_rcu()? +
Answer + +

Quick Quiz 6: +The first and second guarantees require unbelievably strict ordering! +Are all these memory barriers really required? +
Answer + +

+Note that these memory-barrier requirements do not replace the fundamental +RCU requirement that a grace period wait for all pre-existing readers. +On the contrary, the memory barriers called out in this section must operate in +such a way as to enforce this fundamental requirement. +Of course, different implementations enforce this requirement in different +ways, but enforce it they must. + +

RCU Primitives Guaranteed to Execute Unconditionally

+ +

+The common-case RCU primitives are unconditional. +They are invoked, they do their job, and they return, with no possibility +of error, and no need to retry. +This is a key RCU design philosophy. + +

+However, this philosophy is pragmatic rather than pigheaded. +If someone comes up with a good justification for a particular conditional +RCU primitive, it might well be implemented and added. +After all, this guarantee was reverse-engineered, not premeditated. +The unconditional nature of the RCU primitives was initially an +accident of implementation, and later experience with synchronization +primitives with conditional primitives caused me to elevate this +accident to a guarantee. +Therefore, the justification for adding a conditional primitive to +RCU would need to be based on detailed and compelling use cases. + +

Guaranteed Read-to-Write Upgrade

+ +

+As far as RCU is concerned, it is always possible to carry out an +update within an RCU read-side critical section. +For example, that RCU read-side critical section might search for +a given data element, and then might acquire the update-side +spinlock in order to update that element, all while remaining +in that RCU read-side critical section. +Of course, it is necessary to exit the RCU read-side critical section +before invoking synchronize_rcu(), however, this +inconvenience can be avoided through use of the +call_rcu() and kfree_rcu() API members +described later in this document. + +

Quick Quiz 7: +But how does the upgrade-to-write operation exclude other readers? +
Answer + +

+This guarantee allows lookup code to be shared between read-side +and update-side code, and was premeditated, appearing in the earliest +DYNIX/ptx RCU documentation. + +

Fundamental Non-Requirements

+ +

+RCU provides extremely lightweight readers, and its read-side guarantees, +though quite useful, are correspondingly lightweight. +It is therefore all too easy to assume that RCU is guaranteeing more +than it really is. +Of course, the list of things that RCU does not guarantee is infinitely +long, however, the following sections list a few non-guarantees that +have caused confusion. +Except where otherwise noted, these non-guarantees were premeditated. + +

    +
  1. + Readers Impose Minimal Ordering +
  2. + Readers Do Not Exclude Updaters +
  3. + Updaters Only Wait For Old Readers +
  4. + Grace Periods Don't Partition Read-Side Critical Sections +
  5. + Read-Side Critical Sections Don't Partition Grace Periods +
  6. + Disabling Preemption Does Not Block Grace Periods +
+ +

Readers Impose Minimal Ordering

+ +

+Reader-side markers such as rcu_read_lock() and +rcu_read_unlock() provide absolutely no ordering guarantees +except through their interaction with the grace-period APIs such as +synchronize_rcu(). +To see this, consider the following pair of threads: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(x, 1);
+ 5   rcu_read_unlock();
+ 6   rcu_read_lock();
+ 7   WRITE_ONCE(y, 1);
+ 8   rcu_read_unlock();
+ 9 }
+10
+11 void thread1(void)
+12 {
+13   rcu_read_lock();
+14   r1 = READ_ONCE(y);
+15   rcu_read_unlock();
+16   rcu_read_lock();
+17   r2 = READ_ONCE(x);
+18   rcu_read_unlock();
+19 }
+
+
+ +

+After thread0() and thread1() execute +concurrently, it is quite possible to have + +

+
+(r1 == 1 && r2 == 0)
+
+
+ +(that is, y appears to have been assigned before x), +which would not be possible if rcu_read_lock() and +rcu_read_unlock() had much in the way of ordering +properties. +But they do not, so the CPU is within its rights +to do significant reordering. +This is by design: Any significant ordering constraints would slow down +these fast-path APIs. + +

Quick Quiz 8: +Can't the compiler also reorder this code? +
Answer + +

Readers Do Not Exclude Updaters

+ +

+Neither rcu_read_lock() nor rcu_read_unlock() +exclude updates. +All they do is to prevent grace periods from ending. +The following example illustrates this: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   r1 = READ_ONCE(y);
+ 5   if (r1) {
+ 6     do_something_with_nonzero_x();
+ 7     r2 = READ_ONCE(x);
+ 8     WARN_ON(!r2); /* BUG!!! */
+ 9   }
+10   rcu_read_unlock();
+11 }
+12
+13 void thread1(void)
+14 {
+15   spin_lock(&my_lock);
+16   WRITE_ONCE(x, 1);
+17   WRITE_ONCE(y, 1);
+18   spin_unlock(&my_lock);
+19 }
+
+
+ +

+If the thread0() function's rcu_read_lock() +excluded the thread1() function's update, +the WARN_ON() could never fire. +But the fact is that rcu_read_lock() does not exclude +much of anything aside from subsequent grace periods, of which +thread1() has none, so the +WARN_ON() can and does fire. + +

Updaters Only Wait For Old Readers

+ +

+It might be tempting to assume that after synchronize_rcu() +completes, there are no readers executing. +This temptation must be avoided because +new readers can start immediately after synchronize_rcu() +starts, and synchronize_rcu() is under no +obligation to wait for these new readers. + +

Quick Quiz 9: +Suppose that synchronize_rcu() did wait until all readers had completed. +Would the updater be able to rely on this? +
Answer + +

+Grace Periods Don't Partition Read-Side Critical Sections

+ +

+It is tempting to assume that if any part of one RCU read-side critical +section precedes a given grace period, and if any part of another RCU +read-side critical section follows that same grace period, then all of +the first RCU read-side critical section must precede all of the second. +However, this just isn't the case: A single grace period does not +partition the set of RCU read-side critical sections. +An example of this situation can be illustrated as follows, where +x, y, and z are initially all zero: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(a, 1);
+ 5   WRITE_ONCE(b, 1);
+ 6   rcu_read_unlock();
+ 7 }
+ 8
+ 9 void thread1(void)
+10 {
+11   r1 = READ_ONCE(a);
+12   synchronize_rcu();
+13   WRITE_ONCE(c, 1);
+14 }
+15
+16 void thread2(void)
+17 {
+18   rcu_read_lock();
+19   r2 = READ_ONCE(b);
+20   r3 = READ_ONCE(c);
+21   rcu_read_unlock();
+22 }
+
+
+ +

+It turns out that the outcome: + +

+
+(r1 == 1 && r2 == 0 && r3 == 1)
+
+
+ +is entirely possible. +The following figure show how this can happen, with each circled +QS indicating the point at which RCU recorded a +quiescent state for each thread, that is, a state in which +RCU knows that the thread cannot be in the midst of an RCU read-side +critical section that started before the current grace period: + +

GPpartitionReaders1.svg

+ +

+If it is necessary to partition RCU read-side critical sections in this +manner, it is necessary to use two grace periods, where the first +grace period is known to end before the second grace period starts: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(a, 1);
+ 5   WRITE_ONCE(b, 1);
+ 6   rcu_read_unlock();
+ 7 }
+ 8
+ 9 void thread1(void)
+10 {
+11   r1 = READ_ONCE(a);
+12   synchronize_rcu();
+13   WRITE_ONCE(c, 1);
+14 }
+15
+16 void thread2(void)
+17 {
+18   r2 = READ_ONCE(c);
+19   synchronize_rcu();
+20   WRITE_ONCE(d, 1);
+21 }
+22
+23 void thread3(void)
+24 {
+25   rcu_read_lock();
+26   r3 = READ_ONCE(b);
+27   r4 = READ_ONCE(d);
+28   rcu_read_unlock();
+29 }
+
+
+ +

+Here, if (r1 == 1), then +thread0()'s write to b must happen +before the end of thread1()'s grace period. +If in addition (r4 == 1), then +thread3()'s read from b must happen +after the beginning of thread2()'s grace period. +If it is also the case that (r2 == 1), then the +end of thread1()'s grace period must precede the +beginning of thread2()'s grace period. +This mean that the two RCU read-side critical sections cannot overlap, +guaranteeing that (r3 == 1). +As a result, the outcome: + +

+
+(r1 == 1 && r2 == 1 && r3 == 0 && r4 == 1)
+
+
+ +cannot happen. + +

+This non-requirement was also non-premeditated, but became apparent +when studying RCU's interaction with memory ordering. + +

+Read-Side Critical Sections Don't Partition Grace Periods

+ +

+It is also tempting to assume that if an RCU read-side critical section +happens between a pair of grace periods, then those grace periods cannot +overlap. +However, this temptation leads nowhere good, as can be illustrated by +the following, with all variables initially zero: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(a, 1);
+ 5   WRITE_ONCE(b, 1);
+ 6   rcu_read_unlock();
+ 7 }
+ 8
+ 9 void thread1(void)
+10 {
+11   r1 = READ_ONCE(a);
+12   synchronize_rcu();
+13   WRITE_ONCE(c, 1);
+14 }
+15
+16 void thread2(void)
+17 {
+18   rcu_read_lock();
+19   WRITE_ONCE(d, 1);
+20   r2 = READ_ONCE(c);
+21   rcu_read_unlock();
+22 }
+23
+24 void thread3(void)
+25 {
+26   r3 = READ_ONCE(d);
+27   synchronize_rcu();
+28   WRITE_ONCE(e, 1);
+29 }
+30
+31 void thread4(void)
+32 {
+33   rcu_read_lock();
+34   r4 = READ_ONCE(b);
+35   r5 = READ_ONCE(e);
+36   rcu_read_unlock();
+37 }
+
+
+ +

+In this case, the outcome: + +

+
+(r1 == 1 && r2 == 1 && r3 == 1 && r4 == 0 && r5 == 1)
+
+
+ +is entirely possible, as illustrated below: + +

ReadersPartitionGP1.svg

+ +

+Again, an RCU read-side critical section can overlap almost all of a +given grace period, just so long as it does not overlap the entire +grace period. +As a result, an RCU read-side critical section cannot partition a pair +of RCU grace periods. + +

Quick Quiz 10: +How long a sequence of grace periods, each separated by an RCU read-side +critical section, would be required to partition the RCU read-side +critical sections at the beginning and end of the chain? +
Answer + +

+Disabling Preemption Does Not Block Grace Periods

+ +

+There was a time when disabling preemption on any given CPU would block +subsequent grace periods. +However, this was an accident of implementation and is not a requirement. +And in the current Linux-kernel implementation, disabling preemption +on a given CPU in fact does not block grace periods, as Oleg Nesterov +demonstrated. + +

+If you need a preempt-disable region to block grace periods, you need to add +rcu_read_lock() and rcu_read_unlock(), for example +as follows: + +

+
+ 1 preempt_disable();
+ 2 rcu_read_lock();
+ 3 do_something();
+ 4 rcu_read_unlock();
+ 5 preempt_enable();
+ 6
+ 7 /* Spinlocks implicitly disable preemption. */
+ 8 spin_lock(&mylock);
+ 9 rcu_read_lock();
+10 do_something();
+11 rcu_read_unlock();
+12 spin_unlock(&mylock);
+
+
+ +

+In theory, you could enter the RCU read-side critical section first, +but it is more efficient to keep the entire RCU read-side critical +section contained in the preempt-disable region as shown above. +Of course, RCU read-side critical sections that extend outside of +preempt-disable regions will work correctly, but such critical sections +can be preempted, which forces rcu_read_unlock() to do +more work. +And no, this is not an invitation to enclose all of your RCU +read-side critical sections within preempt-disable regions, because +doing so would degrade real-time response. + +

+This non-requirement appeared with preemptible RCU. +If you need a grace period that waits on non-preemptible code regions, use +RCU-sched. + +

Parallelism Facts of Life

+ +

+These parallelism facts of life are by no means specific to RCU, but +the RCU implementation must abide by them. +They therefore bear repeating: + +

    +
  1. Any CPU or task may be delayed at any time, + and any attempts to avoid these delays by disabling + preemption, interrupts, or whatever are completely futile. + This is most obvious in preemptible user-level + environments and in virtualized environments (where + a given guest OS's VCPUs can be preempted at any time by + the underlying hypervisor), but can also happen in bare-metal + environments due to ECC errors, NMIs, and other hardware + events. + Although a delay of more than about 20 seconds can result + in splats, the RCU implementation is obligated to use + algorithms that can tolerate extremely long delays, but where + “extremely long” is not long enough to allow + wrap-around when incrementing a 64-bit counter. +
  2. Both the compiler and the CPU can reorder memory accesses. + Where it matters, RCU must use compiler directives and + memory-barrier instructions to preserve ordering. +
  3. Conflicting writes to memory locations in any given cache line + will result in expensive cache misses. + Greater numbers of concurrent writes and more-frequent + concurrent writes will result in more dramatic slowdowns. + RCU is therefore obligated to use algorithms that have + sufficient locality to avoid significant performance and + scalability problems. +
  4. As a rough rule of thumb, only one CPU's worth of processing + may be carried out under the protection of any given exclusive + lock. + RCU must therefore use scalable locking designs. +
  5. Counters are finite, especially on 32-bit systems. + RCU's use of counters must therefore tolerate counter wrap, + or be designed such that counter wrap would take way more + time than a single system is likely to run. + An uptime of ten years is quite possible, a runtime + of a century much less so. + As an example of the latter, RCU's dyntick-idle nesting counter + allows 54 bits for interrupt nesting level (this counter + is 64 bits even on a 32-bit system). + Overflowing this counter requires 254 + half-interrupts on a given CPU without that CPU ever going idle. + If a half-interrupt happened every microsecond, it would take + 570 years of runtime to overflow this counter, which is currently + believed to be an acceptably long time. +
  6. Linux systems can have thousands of CPUs running a single + Linux kernel in a single shared-memory environment. + RCU must therefore pay close attention to high-end scalability. +
+ +

+This last parallelism fact of life means that RCU must pay special +attention to the preceding facts of life. +The idea that Linux might scale to systems with thousands of CPUs would +have been met with some skepticism in the 1990s, but these requirements +would have otherwise have been unsurprising, even in the early 1990s. + +

Quality-of-Implementation Requirements

+ +

+These sections list quality-of-implementation requirements. +Although an RCU implementation that ignores these requirements could +still be used, it would likely be subject to limitations that would +make it inappropriate for industrial-strength production use. +Classes of quality-of-implementation requirements are as follows: + +

    +

Specialization

+ +

+RCU is and always has been intended primarily for read-mostly situations, as +illustrated by the following figure. +This means that RCU's read-side primitives are optimized, often at the +expense of its update-side primitives. + +

RCUApplicability.svg

+ +

+This focus on read-mostly situations means that RCU must interoperate +with other synchronization primitives. +For example, the add_gp() and remove_gp_synchronous() +examples discussed earlier use RCU to protect readers and locking to +coordinate updaters. +However, the need extends much farther, requiring that a variety of +synchronization primitives be legal within RCU read-side critical sections, +including spinlocks, sequence locks, atomic operations, reference +counters, and memory barriers. + +

Quick Quiz 11: +What about sleeping locks? +
Answer + +

+It often comes as a surprise that many algorithms do not require a +consistent view of data, but many can function in that mode, +with network routing being the poster child. +Internet routing algorithms take significant time to propagate +updates, so that by the time an update arrives at a given system, +that system has been sending network traffic the wrong way for +a considerable length of time. +Having a few threads continue to send traffic the wrong way for a +few more milliseconds is clearly not a problem: In the worst case, +TCP retransmissions will eventually get the data where it needs to go. +In general, when tracking the state of the universe outside of the +computer, some level of inconsistency must be tolerated due to +speed-of-light delays if nothing else. + +

+Furthermore, uncertainty about external state is inherent in many cases. +For example, a pair of veternarians might use heartbeat to determine +whether or not a given cat was alive. +But how long should they wait after the last heartbeat to decide that +the cat is in fact dead? +Waiting less than 400 milliseconds makes no sense because this would +mean that a relaxed cat would be considered to cycle between death +and life more than 100 times per minute. +Moreover, just as with human beings, a cat's heart might stop for +some period of time, so the exact wait period is a judgment call. +One of our pair of veternarians might wait 30 seconds before pronouncing +the cat dead, while the other might insist on waiting a full minute. +The two veternarians would then disagree on the state of the cat during +the final 30 seconds of the minute following the last heartbeat, as +fancifully illustrated below: + +

+ +

+Interestingly enough, this same situation applies to hardware. +When push comes to shove, how do we tell whether or not some +external server has failed? +We send messages to it periodically, and declare it failed if we +don't receive a response within a given period of time. +Policy decisions can usually tolerate short +periods of inconsistency. +The policy was decided some time ago, and is only now being put into +effect, so a few milliseconds of delay is normally inconsequential. + +

+However, there are algorithms that absolutely must see consistent data. +For example, the translation between a user-level SystemV semaphore +ID to the corresponding in-kernel data structure is protected by RCU, +but it is absolutely forbidden to update a semaphore that has just been +removed. +In the Linux kernel, this need for consistency is accommodated by acquiring +spinlocks located in the in-kernel data structure from within +the RCU read-side critical section, and this is indicated by the +green box in the figure above. +Many other techniques may be used, and are in fact used within the +Linux kernel. + +

+In short, RCU is not required to maintain consistency, and other +mechanisms may be used in concert with RCU when consistency is required. +RCU's specialization allows it to do its job extremely well, and its +ability to interoperate with other synchronization mechanisms allows +the right mix of synchronization tools to be used for a given job. + +

Performance and Scalability

+ +

+Energy efficiency is a critical component of performance today, +and Linux-kernel RCU implementations must therefore avoid unnecessarily +awakening idle CPUs. +I cannot claim that this requirement was premeditated. +In fact, I learned of it during a telephone conversation in which I +was given “frank and open” feedback on the importance +of energy efficiency in battery-powered systems and on specific +energy-efficiency shortcomings of the Linux-kernel RCU implementation. +In my experience, the battery-powered embedded community will consider +any unnecessary wakeups to be extremely unfriendly acts. +So much so that mere Linux-kernel-mailing-list posts are +insufficient to vent their ire. + +

+Memory consumption is not particularly important for in most +situations, and has become decreasingly +so as memory sizes have expanded and memory +costs have plummeted. +However, as I learned from Matt Mackall's +bloatwatch +efforts, memory footprint is critically important on single-CPU systems with +non-preemptible (CONFIG_PREEMPT=n) kernels, and thus +tiny RCU +was born. +Josh Triplett has since taken over the small-memory banner with his +Linux kernel tinification +project, which resulted in +SRCU +becoming optional for those kernels not needing it. + +

+The remaining performance requirements are, for the most part, +unsurprising. +For example, in keeping with RCU's read-side specialization, +rcu_dereference() should have negligible overhead (for +example, suppression of a few minor compiler optimizations). +Similarly, in non-preemptible environments, rcu_read_lock() and +rcu_read_unlock() should have exactly zero overhead. + +

+In preemptible environments, in the case where the RCU read-side +critical section was not preempted (as will be the case for the +highest-priority real-time process), rcu_read_lock() and +rcu_read_unlock() should have minimal overhead. +In particular, they should not contain atomic read-modify-write +operations, memory-barrier instructions, preemption disabling, +interrupt disabling, or backwards branches. +However, in the case where the RCU read-side critical section was preempted, +rcu_read_unlock() may acquire spinlocks and disable interrupts. +This is why it is better to nest an RCU read-side critical section +within a preempt-disable region than vice versa, at least in cases +where that critical section is short enough to avoid unduly degrading +real-time latencies. + +

+The synchronize_rcu() grace-period-wait primitive is +optimized for throughput. +It may therefore incur several milliseconds of latency in addition to +the duration of the longest RCU read-side critical section. +On the other hand, multiple concurrent invocations of +synchronize_rcu() are required to use batching optimizations +so that they can be satisfied by a single underlying grace-period-wait +operation. +For example, in the Linux kernel, it is not unusual for a single +grace-period-wait operation to serve more than +1,000 separate invocations +of synchronize_rcu(), thus amortizing the per-invocation +overhead down to nearly zero. +However, the grace-period optimization is also required to avoid +measurable degradation of real-time scheduling and interrupt latencies. + +

+In some cases, the multi-millisecond synchronize_rcu() +latencies are unacceptable. +In these cases, synchronize_rcu_expedited() may be used +instead, reducing the grace-period latency down to a few tens of +microseconds on small systems, at least in cases where the RCU read-side +critical sections are short. +There are currently no special latency requirements for +synchronize_rcu_expedited() on large systems, but, +consistent with the empirical nature of the RCU specification, +that is subject to change. +However, there most definitely are scalability requirements: +A storm of synchronize_rcu_expedited() invocations on 4096 +CPUs should at least make reasonable forward progress. +In return for its shorter latencies, synchronize_rcu_expedited() +is permitted to impose modest degradation of real-time latency +on non-idle online CPUs. +That said, it will likely be necessary to take further steps to reduce this +degradation, hopefully to roughly that of a scheduling-clock interrupt. + +

+There are a number of situations where even +synchronize_rcu_expedited()'s reduced grace-period +latency is unacceptable. +In these situations, the asynchronous call_rcu() can be +used in place of synchronize_rcu() as follows: + +

+
+ 1 struct foo {
+ 2   int a;
+ 3   int b;
+ 4   struct rcu_head rh;
+ 5 };
+ 6
+ 7 static void remove_gp_cb(struct rcu_head *rhp)
+ 8 {
+ 9   struct foo *p = container_of(rhp, struct foo, rh);
+10
+11   kfree(p);
+12 }
+13
+14 bool remove_gp_asynchronous(void)
+15 {
+16   struct foo *p;
+17
+18   spin_lock(&gp_lock);
+19   p = rcu_dereference(gp);
+20   if (!p) {
+21     spin_unlock(&gp_lock);
+22     return false;
+23   }
+24   rcu_assign_pointer(gp, NULL);
+25   call_rcu(&p->rh, remove_gp_cb);
+26   spin_unlock(&gp_lock);
+27   return true;
+28 }
+
+
+ +

+A definition of struct foo is finally needed, and appears +on lines 1-5. +The function remove_gp_cb() is passed to call_rcu() +on line 25, and will be invoked after the end of a subsequent +grace period. +This gets the same effect as remove_gp_synchronous(), +but without forcing the updater to wait for a grace period to elapse. +The call_rcu() function may be used in a number of +situations where neither synchronize_rcu() nor +synchronize_rcu_expedited() would be legal, +including within preempt-disable code, local_bh_disable() code, +interrupt-disable code, and interrupt handlers. +However, even call_rcu() is illegal within NMI handlers. +The callback function (remove_gp_cb() in this case) will be +executed within softirq (software interrupt) environment within the +Linux kernel, +either within a real softirq handler or under the protection +of local_bh_disable(). +In both the Linux kernel and in userspace, it is bad practice to +write an RCU callback function that takes too long. +Long-running operations should be relegated to separate threads or +(in the Linux kernel) workqueues. + +

Quick Quiz 12: +Why does line 19 use rcu_access_pointer()? +After all, call_rcu() on line 25 stores into the +structure, which would interact badly with concurrent insertions. +Doesn't this mean that rcu_dereference() is required? +
Answer + +

+However, all that remove_gp_cb() is doing is +invoking kfree() on the data element. +This is a common idiom, and is supported by kfree_rcu(), +which allows “fire and forget” operation as shown below: + +

+
+ 1 struct foo {
+ 2   int a;
+ 3   int b;
+ 4   struct rcu_head rh;
+ 5 };
+ 6
+ 7 bool remove_gp_faf(void)
+ 8 {
+ 9   struct foo *p;
+10
+11   spin_lock(&gp_lock);
+12   p = rcu_dereference(gp);
+13   if (!p) {
+14     spin_unlock(&gp_lock);
+15     return false;
+16   }
+17   rcu_assign_pointer(gp, NULL);
+18   kfree_rcu(p, rh);
+19   spin_unlock(&gp_lock);
+20   return true;
+21 }
+
+
+ +

+Note that remove_gp_faf() simply invokes +kfree_rcu() and proceeds, without any need to pay any +further attention to the subsequent grace period and kfree(). +It is permissible to invoke kfree_rcu() from the same +environments as for call_rcu(). +Interestingly enough, DYNIX/ptx had the equivalents of +call_rcu() and kfree_rcu(), but not +synchronize_rcu(). +This was due to the fact that RCU was not heavily used within DYNIX/ptx, +so the very few places that needed something like +synchronize_rcu() simply open-coded it. + +

Quick Quiz 13: +Earlier it was claimed that call_rcu() and +kfree_rcu() allowed updaters to avoid being blocked +by readers. +But how can that be correct, given that the invocation of the callback +and the freeing of the memory (respectively) must still wait for +a grace period to elapse? +
Answer + +

+But what if the updater must wait for the completion of code to be +executed after the end of the grace period, but has other tasks +that can be carried out in the meantime? +The polling-style get_state_synchronize_rcu() and +cond_synchronize_rcu() functions may be used for this +purpose, as shown below: + +

+
+ 1 bool remove_gp_poll(void)
+ 2 {
+ 3   struct foo *p;
+ 4   unsigned long s;
+ 5
+ 6   spin_lock(&gp_lock);
+ 7   p = rcu_access_pointer(gp);
+ 8   if (!p) {
+ 9     spin_unlock(&gp_lock);
+10     return false;
+11   }
+12   rcu_assign_pointer(gp, NULL);
+13   spin_unlock(&gp_lock);
+14   s = get_state_synchronize_rcu();
+15   do_something_while_waiting();
+16   cond_synchronize_rcu(s);
+17   kfree(p);
+18   return true;
+19 }
+
+
+ +

+On line 14, get_state_synchronize_rcu() obtains a +“cookie” from RCU, +then line 15 carries out other tasks, +and finally, line 16 returns immediately if a grace period has +elapsed in the meantime, but otherwise waits as required. +The need for get_state_synchronize_rcu and +cond_synchronize_rcu() has appeared quite recently, +so it is too early to tell whether they will stand the test of time. + +

+RCU thus provides a range of tools to allow updaters to strike the +required tradeoff between latency, flexibility and CPU overhead. + +

Composability

+ +

+Composability has received much attention in recent years, perhaps in part +due to the collision of multicore hardware with object-oriented techniques +designed in single-threaded environments for single-threaded use. +And in theory, RCU read-side critical sections may be composed, and in +fact may be nested arbitrarily deeply. +In practice, as with all real-world implementations of composable +constructs, there are limitations. + +

+Implementations of RCU for which rcu_read_lock() +and rcu_read_unlock() generate no code, such as +Linux-kernel RCU when CONFIG_PREEMPT=n, can be +nested arbitrarily deeply. +After all, there is no overhead. +Except that if all these instances of rcu_read_lock() +and rcu_read_unlock() are visible to the compiler, +compilation will eventually fail due to exhausting memory, +mass storage, or user patience, whichever comes first. +If the nesting is not visible to the compiler, as is the case with +mutually recursive functions each in its own translation unit, +stack overflow will result. +If the nesting takes the form of loops, either the control variable +will overflow or (in the Linux kernel) you will get an RCU CPU stall warning. +Nevertheless, this class of RCU implementations is one +of the most composable constructs in existence. + +

+RCU implementations that explicitly track nesting depth +are limited by the nesting-depth counter. +For example, the Linux kernel's preemptible RCU limits nesting to +INT_MAX. +This should suffice for almost all practical purposes. +That said, a consecutive pair of RCU read-side critical sections +between which there is an operation that waits for a grace period +cannot be enclosed in another RCU read-side critical section. +This is because it is not legal to wait for a grace period within +an RCU read-side critical section: To do so would result either +in deadlock or +in RCU implicitly splitting the enclosing RCU read-side critical +section, neither of which is conducive to a long-lived and prosperous +kernel. + +

+It is worth noting that RCU is not alone in limiting composability. +For example, many transactional-memory implementations prohibit +composing a pair of transactions separated by an irrevocable +operation (for example, a network receive operation). +For another example, lock-based critical sections can be composed +surprisingly freely, but only if deadlock is avoided. + +

+In short, although RCU read-side critical sections are highly composable, +care is required in some situations, just as is the case for any other +composable synchronization mechanism. + +

Corner Cases

+ +

+A given RCU workload might have an endless and intense stream of +RCU read-side critical sections, perhaps even so intense that there +was never a point in time during which there was not at least one +RCU read-side critical section in flight. +RCU cannot allow this situation to block grace periods: As long as +all the RCU read-side critical sections are finite, grace periods +must also be finite. + +

+That said, preemptible RCU implementations could potentially result +in RCU read-side critical sections being preempted for long durations, +which has the effect of creating a long-duration RCU read-side +critical section. +This situation can arise only in heavily loaded systems, but systems using +real-time priorities are of course more vulnerable. +Therefore, RCU priority boosting is provided to help deal with this +case. +That said, the exact requirements on RCU priority boosting will likely +evolve as more experience accumulates. + +

+Other workloads might have very high update rates. +Although one can argue that such workloads should instead use +something other than RCU, the fact remains that RCU must +handle such workloads gracefully. +This requirement is another factor driving batching of grace periods, +but it is also the driving force behind the checks for large numbers +of queued RCU callbacks in the call_rcu() code path. +Finally, high update rates should not delay RCU read-side critical +sections, although some read-side delays can occur when using +synchronize_rcu_expedited(), courtesy of this function's use +of try_stop_cpus(). +(In the future, synchronize_rcu_expedited() will be +converted to use lighter-weight inter-processor interrupts (IPIs), +but this will still disturb readers, though to a much smaller degree.) + +

+Although all three of these corner cases were understood in the early +1990s, a simple user-level test consisting of close(open(path)) +in a tight loop +in the early 2000s suddenly provided a much deeper appreciation of the +high-update-rate corner case. +This test also motivated addition of some RCU code to react to high update +rates, for example, if a given CPU finds itself with more than 10,000 +RCU callbacks queued, it will cause RCU to take evasive action by +more aggressively starting grace periods and more aggressively forcing +completion of grace-period processing. +This evasive action causes the grace period to complete more quickly, +but at the cost of restricting RCU's batching optimizations, thus +increasing the CPU overhead incurred by that grace period. + +

+Software-Engineering Requirements

+ +

+Between Murphy's Law and “To err is human”, it is necessary to +guard against mishaps and misuse: + +

    +
  1. It is all too easy to forget to use rcu_read_lock() + everywhere that it is needed, so kernels built with + CONFIG_PROVE_RCU=y will spat if + rcu_dereference() is used outside of an + RCU read-side critical section. + Update-side code can use rcu_dereference_protected(), + which takes a + lockdep expression + to indicate what is providing the protection. + If the indicated protection is not provided, a lockdep splat + is emitted. + +

    + Code shared between readers and updaters can use + rcu_dereference_check(), which also takes a + lockdep expression, and emits a lockdep splat if neither + rcu_read_lock() nor the indicated protection + is in place. + In addition, rcu_dereference_raw() is used in those + (hopefully rare) cases where the required protection cannot + be easily described. + Finally, rcu_read_lock_held() is provided to + allow a function to verify that it has been invoked within + an RCU read-side critical section. + I was made aware of this set of requirements shortly after Thomas + Gleixner audited a number of RCU uses. +

  2. A given function might wish to check for RCU-related preconditions + upon entry, before using any other RCU API. + The rcu_lockdep_assert() does this job, + asserting the expression in kernels having lockdep enabled + and doing nothing otherwise. +
  3. It is also easy to forget to use rcu_assign_pointer() + and rcu_dereference(), perhaps (incorrectly) + substituting a simple assignment. + To catch this sort of error, a given RCU-protected pointer may be + tagged with __rcu, after which running sparse + with CONFIG_SPARSE_RCU_POINTER=y will complain + about simple-assignment accesses to that pointer. + Arnd Bergmann made me aware of this requirement, and also + supplied the needed + patch series. +
  4. Kernels built with CONFIG_DEBUG_OBJECTS_RCU_HEAD=y + will splat if a data element is passed to call_rcu() + twice in a row, without a grace period in between. + (This error is similar to a double free.) + The corresponding rcu_head structures that are + dynamically allocated are automatically tracked, but + rcu_head structures allocated on the stack + must be initialized with init_rcu_head_on_stack() + and cleaned up with destroy_rcu_head_on_stack(). + Similarly, statically allocated non-stack rcu_head + structures must be initialized with init_rcu_head() + and cleaned up with destroy_rcu_head(). + Mathieu Desnoyers made me aware of this requirement, and also + supplied the needed + patch. +
  5. An infinite loop in an RCU read-side critical section will + eventually trigger an RCU CPU stall warning splat, with + the duration of “eventually” being controlled by the + RCU_CPU_STALL_TIMEOUT Kconfig option, or, + alternatively, by the + rcupdate.rcu_cpu_stall_timeout boot/sysfs + parameter. + However, RCU is not obligated to produce this splat + unless there is a grace period waiting on that particular + RCU read-side critical section. +

    + Some extreme workloads might intentionally delay + RCU grace periods, and systems running those workloads can + be booted with rcupdate.rcu_cpu_stall_suppress + to suppress the splats. + This kernel parameter may also be set via sysfs. + Furthermore, RCU CPU stall warnings are counter-productive + during sysrq dumps and during panics. + RCU therefore supplies the rcu_sysrq_start() and + rcu_sysrq_end() API members to be called before + and after long sysrq dumps. + RCU also supplies the rcu_panic() notifier that is + automatically invoked at the beginning of a panic to suppress + further RCU CPU stall warnings. + +

    + This requirement made itself known in the early 1990s, pretty + much the first time that it was necessary to debug a CPU stall. + That said, the initial implementation in DYNIX/ptx was quite + generic in comparison with that of Linux. +

  6. Although it would be very good to detect pointers leaking out + of RCU read-side critical sections, there is currently no + good way of doing this. + One complication is the need to distinguish between pointers + leaking and pointers that have been handed off from RCU to + some other synchronization mechanism, for example, reference + counting. +
  7. In kernels built with CONFIG_RCU_TRACE=y, RCU-related + information is provided via both debugfs and event tracing. +
  8. Open-coded use of rcu_assign_pointer() and + rcu_dereference() to create typical linked + data structures can be surprisingly error-prone. + Therefore, RCU-protected + linked lists + and, more recently, RCU-protected + hash tables + are available. + Many other special-purpose RCU-protected data structures are + available in the Linux kernel and the userspace RCU library. +
  9. Some linked structures are created at compile time, but still + require __rcu checking. + The RCU_POINTER_INITIALIZER() macro serves this + purpose. +
  10. It is not necessary to use rcu_assign_pointer() + when creating linked structures that are to be published via + a single external pointer. + The RCU_INIT_POINTER() macro is provided for + this task and also for assigning NULL pointers + at runtime. +
+ +

+This not a hard-and-fast list: RCU's diagnostic capabilities will +continue to be guided by the number and type of usage bugs found +in real-world RCU usage. + +

Linux Kernel Complications

+ +

+The Linux kernel provides an interesting environment for all kinds of +software, including RCU. +Some of the relevant points of interest are as follows: + +

    +
  1. Configuration. +
  2. Firmware Interface. +
  3. Early Boot. +
  4. + Interrupts and non-maskable interrupts (NMIs). +
  5. Loadable Modules. +
  6. Hotplug CPU. +
  7. Scheduler and RCU. +
  8. Tracing and RCU. +
  9. Energy Efficiency. +
  10. Memory Efficiency. +
  11. + Performance, Scalability, Response Time, and Reliability. +
+ +

+This list is probably incomplete, but it does give a feel for the +most notable Linux-kernel complications. +Each of the following sections covers one of the above topics. + +

Configuration

+ +

+RCU's goal is automatic configuration, so that almost nobody +needs to worry about RCU's Kconfig options. +And for almost all users, RCU does in fact work well +“out of the box.” + +

+However, there are specialized use cases that are handled by +kernel boot parameters and Kconfig options. +Unfortunately, the Kconfig system will explicitly ask users +about new Kconfig options, which requires almost all of them +be hidden behind a CONFIG_RCU_EXPERT Kconfig option. + +

+This all should be quite obvious, but the fact remains that +Linus Torvalds recently had to +remind +me of this requirement. + +

Firmware Interface

+ +

+In many cases, kernel obtains information about the system from the +firmware, and sometimes things are lost in translation. +Or the translation is accurate, but the original message is bogus. + +

+For example, some systems' firmware overreports the number of CPUs, +sometimes by a large factor. +If RCU naively believed the firmware, as it used to do, +it would create too many per-CPU kthreads. +Although the resulting system will still run correctly, the extra +kthreads needlessly consume memory and can cause confusion +when they show up in ps listings. + +

+RCU must therefore wait for a given CPU to actually come online before +it can allow itself to believe that the CPU actually exists. +The resulting “ghost CPUs” (which are never going to +come online) cause a number of +interesting complications. + +

Early Boot

+ +

+The Linux kernel's boot sequence is an interesting process, +and RCU is used early, even before rcu_init() +is invoked. +In fact, a number of RCU's primitives can be used as soon as the +initial task's task_struct is available and the +boot CPU's per-CPU variables are set up. +The read-side primitives (rcu_read_lock(), +rcu_read_unlock(), rcu_dereference(), +and rcu_access_pointer()) will operate normally very early on, +as will rcu_assign_pointer(). + +

+Although call_rcu() may be invoked at any +time during boot, callbacks are not guaranteed to be invoked until after +the scheduler is fully up and running. +This delay in callback invocation is due to the fact that RCU does not +invoke callbacks until it is fully initialized, and this full initialization +cannot occur until after the scheduler has initialized itself to the +point where RCU can spawn and run its kthreads. +In theory, it would be possible to invoke callbacks earlier, +however, this is not a panacea because there would be severe restrictions +on what operations those callbacks could invoke. + +

+Perhaps surprisingly, synchronize_rcu(), +synchronize_rcu_bh() +(discussed below), +and +synchronize_sched() +will all operate normally +during very early boot, the reason being that there is only one CPU +and preemption is disabled. +This means that the call synchronize_rcu() (or friends) +itself is a quiescent +state and thus a grace period, so the early-boot implementation can +be a no-op. + +

+Both synchronize_rcu_bh() and synchronize_sched() +continue to operate normally through the remainder of boot, courtesy +of the fact that preemption is disabled across their RCU read-side +critical sections and also courtesy of the fact that there is still +only one CPU. +However, once the scheduler starts initializing, preemption is enabled. +There is still only a single CPU, but the fact that preemption is enabled +means that the no-op implementation of synchronize_rcu() no +longer works in CONFIG_PREEMPT=y kernels. +Therefore, as soon as the scheduler starts initializing, the early-boot +fastpath is disabled. +This means that synchronize_rcu() switches to its runtime +mode of operation where it posts callbacks, which in turn means that +any call to synchronize_rcu() will block until the corresponding +callback is invoked. +Unfortunately, the callback cannot be invoked until RCU's runtime +grace-period machinery is up and running, which cannot happen until +the scheduler has initialized itself sufficiently to allow RCU's +kthreads to be spawned. +Therefore, invoking synchronize_rcu() during scheduler +initialization can result in deadlock. + +

Quick Quiz 14: +So what happens with synchronize_rcu() during +scheduler initialization for CONFIG_PREEMPT=n +kernels? +
Answer + +

+I learned of these boot-time requirements as a result of a series of +system hangs. + +

Interrupts and NMIs

+ +

+The Linux kernel has interrupts, and RCU read-side critical sections are +legal within interrupt handlers and within interrupt-disabled regions +of code, as are invocations of call_rcu(). + +

+Some Linux-kernel architectures can enter an interrupt handler from +non-idle process context, and then just never leave it, instead stealthily +transitioning back to process context. +This trick is sometimes used to invoke system calls from inside the kernel. +These “half-interrupts” mean that RCU has to be very careful +about how it counts interrupt nesting levels. +I learned of this requirement the hard way during a rewrite +of RCU's dyntick-idle code. + +

+The Linux kernel has non-maskable interrupts (NMIs), and +RCU read-side critical sections are legal within NMI handlers. +Thankfully, RCU update-side primitives, including +call_rcu(), are prohibited within NMI handlers. + +

+The name notwithstanding, some Linux-kernel architectures +can have nested NMIs, which RCU must handle correctly. +Andy Lutomirski +surprised me +with this requirement; +he also kindly surprised me with +an algorithm +that meets this requirement. + +

Loadable Modules

+ +

+The Linux kernel has loadable modules, and these modules can +also be unloaded. +After a given module has been unloaded, any attempt to call +one of its functions results in a segmentation fault. +The module-unload functions must therefore cancel any +delayed calls to loadable-module functions, for example, +any outstanding mod_timer() must be dealt with +via del_timer_sync() or similar. + +

+Unfortunately, there is no way to cancel an RCU callback; +once you invoke call_rcu(), the callback function is +going to eventually be invoked, unless the system goes down first. +Because it is normally considered socially irresponsible to crash the system +in response to a module unload request, we need some other way +to deal with in-flight RCU callbacks. + +

+RCU therefore provides +rcu_barrier(), +which waits until all in-flight RCU callbacks have been invoked. +If a module uses call_rcu(), its exit function should therefore +prevent any future invocation of call_rcu(), then invoke +rcu_barrier(). +In theory, the underlying module-unload code could invoke +rcu_barrier() unconditionally, but in practice this would +incur unacceptable latencies. + +

+Nikita Danilov noted this requirement for an analogous filesystem-unmount +situation, and Dipankar Sarma incorporated rcu_barrier() into RCU. +The need for rcu_barrier() for module unloading became +apparent later. + +

Hotplug CPU

+ +

+The Linux kernel supports CPU hotplug, which means that CPUs +can come and go. +It is of course illegal to use any RCU API member from an offline CPU. +This requirement was present from day one in DYNIX/ptx, but +on the other hand, the Linux kernel's CPU-hotplug implementation +is “interesting.” + +

+The Linux-kernel CPU-hotplug implementation has notifiers that +are used to allow the various kernel subsystems (including RCU) +to respond appropriately to a given CPU-hotplug operation. +Most RCU operations may be invoked from CPU-hotplug notifiers, +including even normal synchronous grace-period operations +such as synchronize_rcu(). +However, expedited grace-period operations such as +synchronize_rcu_expedited() are not supported, +due to the fact that current implementations block CPU-hotplug +operations, which could result in deadlock. + +

+In addition, all-callback-wait operations such as +rcu_barrier() are also not supported, due to the +fact that there are phases of CPU-hotplug operations where +the outgoing CPU's callbacks will not be invoked until after +the CPU-hotplug operation ends, which could also result in deadlock. + +

Scheduler and RCU

+ +

+RCU depends on the scheduler, and the scheduler uses RCU to +protect some of its data structures. +This means the scheduler is forbidden from acquiring +the runqueue locks and the priority-inheritance locks +in the middle of an outermost RCU read-side critical section unless either +(1) it releases them before exiting that same +RCU read-side critical section, or +(2) interrupts are disabled across +that entire RCU read-side critical section. +This same prohibition also applies (recursively!) to any lock that is acquired +while holding any lock to which this prohibition applies. +Adhering to this rule prevents preemptible RCU from invoking +rcu_read_unlock_special() while either runqueue or +priority-inheritance locks are held, thus avoiding deadlock. + +

+Prior to v4.4, it was only necessary to disable preemption across +RCU read-side critical sections that acquired scheduler locks. +In v4.4, expedited grace periods started using IPIs, and these +IPIs could force a rcu_read_unlock() to take the slowpath. +Therefore, this expedited-grace-period change required disabling of +interrupts, not just preemption. + +

+For RCU's part, the preemptible-RCU rcu_read_unlock() +implementation must be written carefully to avoid similar deadlocks. +In particular, rcu_read_unlock() must tolerate an +interrupt where the interrupt handler invokes both +rcu_read_lock() and rcu_read_unlock(). +This possibility requires rcu_read_unlock() to use +negative nesting levels to avoid destructive recursion via +interrupt handler's use of RCU. + +

+This pair of mutual scheduler-RCU requirements came as a +complete surprise. + +

+As noted above, RCU makes use of kthreads, and it is necessary to +avoid excessive CPU-time accumulation by these kthreads. +This requirement was no surprise, but RCU's violation of it +when running context-switch-heavy workloads when built with +CONFIG_NO_HZ_FULL=y +did come as a surprise [PDF]. +RCU has made good progress towards meeting this requirement, even +for context-switch-have CONFIG_NO_HZ_FULL=y workloads, +but there is room for further improvement. + +

Tracing and RCU

+ +

+It is possible to use tracing on RCU code, but tracing itself +uses RCU. +For this reason, rcu_dereference_raw_notrace() +is provided for use by tracing, which avoids the destructive +recursion that could otherwise ensue. +This API is also used by virtualization in some architectures, +where RCU readers execute in environments in which tracing +cannot be used. +The tracing folks both located the requirement and provided the +needed fix, so this surprise requirement was relatively painless. + +

Energy Efficiency

+ +

+Interrupting idle CPUs is considered socially unacceptable, +especially by people with battery-powered embedded systems. +RCU therefore conserves energy by detecting which CPUs are +idle, including tracking CPUs that have been interrupted from idle. +This is a large part of the energy-efficiency requirement, +so I learned of this via an irate phone call. + +

+Because RCU avoids interrupting idle CPUs, it is illegal to +execute an RCU read-side critical section on an idle CPU. +(Kernels built with CONFIG_PROVE_RCU=y will splat +if you try it.) +The RCU_NONIDLE() macro and _rcuidle +event tracing is provided to work around this restriction. +In addition, rcu_is_watching() may be used to +test whether or not it is currently legal to run RCU read-side +critical sections on this CPU. +I learned of the need for diagnostics on the one hand +and RCU_NONIDLE() on the other while inspecting +idle-loop code. +Steven Rostedt supplied _rcuidle event tracing, +which is used quite heavily in the idle loop. + +

+It is similarly socially unacceptable to interrupt an +nohz_full CPU running in userspace. +RCU must therefore track nohz_full userspace +execution. +And in +CONFIG_NO_HZ_FULL_SYSIDLE=y +kernels, RCU must separately track idle CPUs on the one hand and +CPUs that are either idle or executing in userspace on the other. +In both cases, RCU must be able to sample state at two points in +time, and be able to determine whether or not some other CPU spent +any time idle and/or executing in userspace. + +

+These energy-efficiency requirements have proven quite difficult to +understand and to meet, for example, there have been more than five +clean-sheet rewrites of RCU's energy-efficiency code, the last of +which was finally able to demonstrate +real energy savings running on real hardware [PDF]. +As noted earlier, +I learned of many of these requirements via angry phone calls: +Flaming me on the Linux-kernel mailing list was apparently not +sufficient to fully vent their ire at RCU's energy-efficiency bugs! + +

Memory Efficiency

+ +

+Although small-memory non-realtime systems can simply use Tiny RCU, +code size is only one aspect of memory efficiency. +Another aspect is the size of the rcu_head structure +used by call_rcu() and kfree_rcu(). +Although this structure contains nothing more than a pair of pointers, +it does appear in many RCU-protected data structures, including +some that are size critical. +The page structure is a case in point, as evidenced by +the many occurrences of the union keyword within that structure. + +

+This need for memory efficiency is one reason that RCU uses hand-crafted +singly linked lists to track the rcu_head structures that +are waiting for a grace period to elapse. +It is also the reason why rcu_head structures do not contain +debug information, such as fields tracking the file and line of the +call_rcu() or kfree_rcu() that posted them. +Although this information might appear in debug-only kernel builds at some +point, in the meantime, the ->func field will often provide +the needed debug information. + +

+However, in some cases, the need for memory efficiency leads to even +more extreme measures. +Returning to the page structure, the rcu_head field +shares storage with a great many other structures that are used at +various points in the corresponding page's lifetime. +In order to correctly resolve certain +race conditions, +the Linux kernel's memory-management subsystem needs a particular bit +to remain zero during all phases of grace-period processing, +and that bit happens to map to the bottom bit of the +rcu_head structure's ->next field. +RCU makes this guarantee as long as call_rcu() +is used to post the callback, as opposed to kfree_rcu() +or some future “lazy” +variant of call_rcu() that might one day be created for +energy-efficiency purposes. + +

+Performance, Scalability, Response Time, and Reliability

+ +

+Expanding on the +earlier discussion, +RCU is used heavily by hot code paths in performance-critical +portions of the Linux kernel's networking, security, virtualization, +and scheduling code paths. +RCU must therefore use efficient implementations, especially in its +read-side primitives. +To that end, it would be good if preemptible RCU's implementation +of rcu_read_lock() could be inlined, however, doing +this requires resolving #include issues with the +task_struct structure. + +

+The Linux kernel supports hardware configurations with up to +4096 CPUs, which means that RCU must be extremely scalable. +Algorithms that involve frequent acquisitions of global locks or +frequent atomic operations on global variables simply cannot be +tolerated within the RCU implementation. +RCU therefore makes heavy use of a combining tree based on the +rcu_node structure. +RCU is required to tolerate all CPUs continuously invoking any +combination of RCU's runtime primitives with minimal per-operation +overhead. +In fact, in many cases, increasing load must decrease the +per-operation overhead, witness the batching optimizations for +synchronize_rcu(), call_rcu(), +synchronize_rcu_expedited(), and rcu_barrier(). +As a general rule, RCU must cheerfully accept whatever the +rest of the Linux kernel decides to throw at it. + +

+The Linux kernel is used for real-time workloads, especially +in conjunction with the +-rt patchset. +The real-time-latency response requirements are such that the +traditional approach of disabling preemption across RCU +read-side critical sections is inappropriate. +Kernels built with CONFIG_PREEMPT=y therefore +use an RCU implementation that allows RCU read-side critical +sections to be preempted. +This requirement made its presence known after users made it +clear that an earlier +real-time patch +did not meet their needs, in conjunction with some +RCU issues +encountered by a very early version of the -rt patchset. + +

+In addition, RCU must make do with a sub-100-microsecond real-time latency +budget. +In fact, on smaller systems with the -rt patchset, the Linux kernel +provides sub-20-microsecond real-time latencies for the whole kernel, +including RCU. +RCU's scalability and latency must therefore be sufficient for +these sorts of configurations. +To my surprise, the sub-100-microsecond real-time latency budget + +applies to even the largest systems [PDF], +up to and including systems with 4096 CPUs. +This real-time requirement motivated the grace-period kthread, which +also simplified handling of a number of race conditions. + +

+Finally, RCU's status as a synchronization primitive means that +any RCU failure can result in arbitrary memory corruption that can be +extremely difficult to debug. +This means that RCU must be extremely reliable, which in +practice also means that RCU must have an aggressive stress-test +suite. +This stress-test suite is called rcutorture. + +

+Although the need for rcutorture was no surprise, +the current immense popularity of the Linux kernel is posing +interesting—and perhaps unprecedented—validation +challenges. +To see this, keep in mind that there are well over one billion +instances of the Linux kernel running today, given Android +smartphones, Linux-powered televisions, and servers. +This number can be expected to increase sharply with the advent of +the celebrated Internet of Things. + +

+Suppose that RCU contains a race condition that manifests on average +once per million years of runtime. +This bug will be occurring about three times per day across +the installed base. +RCU could simply hide behind hardware error rates, given that no one +should really expect their smartphone to last for a million years. +However, anyone taking too much comfort from this thought should +consider the fact that in most jurisdictions, a successful multi-year +test of a given mechanism, which might include a Linux kernel, +suffices for a number of types of safety-critical certifications. +In fact, rumor has it that the Linux kernel is already being used +in production for safety-critical applications. +I don't know about you, but I would feel quite bad if a bug in RCU +killed someone. +Which might explain my recent focus on validation and verification. + +

Other RCU Flavors

+ +

+One of the more surprising things about RCU is that there are now +no fewer than five flavors, or API families. +In addition, the primary flavor that has been the sole focus up to +this point has two different implementations, non-preemptible and +preemptible. +The other four flavors are listed below, with requirements for each +described in a separate section. + +

    +
  1. Bottom-Half Flavor +
  2. Sched Flavor +
  3. Sleepable RCU +
  4. Tasks RCU +
+ +

Bottom-Half Flavor

+ +

+The softirq-disable (AKA “bottom-half”, +hence the “_bh” abbreviations) +flavor of RCU, or RCU-bh, was developed by +Dipankar Sarma to provide a flavor of RCU that could withstand the +network-based denial-of-service attacks researched by Robert +Olsson. +These attacks placed so much networking load on the system +that some of the CPUs never exited softirq execution, +which in turn prevented those CPUs from ever executing a context switch, +which, in the RCU implementation of that time, prevented grace periods +from ever ending. +The result was an out-of-memory condition and a system hang. + +

+The solution was the creation of RCU-bh, which does +local_bh_disable() +across its read-side critical sections, and which uses the transition +from one type of softirq processing to another as a quiescent state +in addition to context switch, idle, user mode, and offline. +This means that RCU-bh grace periods can complete even when some of +the CPUs execute in softirq indefinitely, thus allowing algorithms +based on RCU-bh to withstand network-based denial-of-service attacks. + +

+Because +rcu_read_lock_bh() and rcu_read_unlock_bh() +disable and re-enable softirq handlers, any attempt to start a softirq +handlers during the +RCU-bh read-side critical section will be deferred. +In this case, rcu_read_unlock_bh() +will invoke softirq processing, which can take considerable time. +One can of course argue that this softirq overhead should be associated +with the code following the RCU-bh read-side critical section rather +than rcu_read_unlock_bh(), but the fact +is that most profiling tools cannot be expected to make this sort +of fine distinction. +For example, suppose that a three-millisecond-long RCU-bh read-side +critical section executes during a time of heavy networking load. +There will very likely be an attempt to invoke at least one softirq +handler during that three milliseconds, but any such invocation will +be delayed until the time of the rcu_read_unlock_bh(). +This can of course make it appear at first glance as if +rcu_read_unlock_bh() was executing very slowly. + +

+The +RCU-bh API +includes +rcu_read_lock_bh(), +rcu_read_unlock_bh(), +rcu_dereference_bh(), +rcu_dereference_bh_check(), +synchronize_rcu_bh(), +synchronize_rcu_bh_expedited(), +call_rcu_bh(), +rcu_barrier_bh(), and +rcu_read_lock_bh_held(). + +

Sched Flavor

+ +

+Before preemptible RCU, waiting for an RCU grace period had the +side effect of also waiting for all pre-existing interrupt +and NMI handlers. +However, there are legitimate preemptible-RCU implementations that +do not have this property, given that any point in the code outside +of an RCU read-side critical section can be a quiescent state. +Therefore, RCU-sched was created, which follows “classic” +RCU in that an RCU-sched grace period waits for for pre-existing +interrupt and NMI handlers. +In kernels built with CONFIG_PREEMPT=n, the RCU and RCU-sched +APIs have identical implementations, while kernels built with +CONFIG_PREEMPT=y provide a separate implementation for each. + +

+Note well that in CONFIG_PREEMPT=y kernels, +rcu_read_lock_sched() and rcu_read_unlock_sched() +disable and re-enable preemption, respectively. +This means that if there was a preemption attempt during the +RCU-sched read-side critical section, rcu_read_unlock_sched() +will enter the scheduler, with all the latency and overhead entailed. +Just as with rcu_read_unlock_bh(), this can make it look +as if rcu_read_unlock_sched() was executing very slowly. +However, the highest-priority task won't be preempted, so that task +will enjoy low-overhead rcu_read_unlock_sched() invocations. + +

+The +RCU-sched API +includes +rcu_read_lock_sched(), +rcu_read_unlock_sched(), +rcu_read_lock_sched_notrace(), +rcu_read_unlock_sched_notrace(), +rcu_dereference_sched(), +rcu_dereference_sched_check(), +synchronize_sched(), +synchronize_rcu_sched_expedited(), +call_rcu_sched(), +rcu_barrier_sched(), and +rcu_read_lock_sched_held(). +However, anything that disables preemption also marks an RCU-sched +read-side critical section, including +preempt_disable() and preempt_enable(), +local_irq_save() and local_irq_restore(), +and so on. + +

Sleepable RCU

+ +

+For well over a decade, someone saying “I need to block within +an RCU read-side critical section” was a reliable indication +that this someone did not understand RCU. +After all, if you are always blocking in an RCU read-side critical +section, you can probably afford to use a higher-overhead synchronization +mechanism. +However, that changed with the advent of the Linux kernel's notifiers, +whose RCU read-side critical +sections almost never sleep, but sometimes need to. +This resulted in the introduction of +sleepable RCU, +or SRCU. + +

+SRCU allows different domains to be defined, with each such domain +defined by an instance of an srcu_struct structure. +A pointer to this structure must be passed in to each SRCU function, +for example, synchronize_srcu(&ss), where +ss is the srcu_struct structure. +The key benefit of these domains is that a slow SRCU reader in one +domain does not delay an SRCU grace period in some other domain. +That said, one consequence of these domains is that read-side code +must pass a “cookie” from srcu_read_lock() +to srcu_read_unlock(), for example, as follows: + +

+
+ 1 int idx;
+ 2
+ 3 idx = srcu_read_lock(&ss);
+ 4 do_something();
+ 5 srcu_read_unlock(&ss, idx);
+
+
+ +

+As noted above, it is legal to block within SRCU read-side critical sections, +however, with great power comes great responsibility. +If you block forever in one of a given domain's SRCU read-side critical +sections, then that domain's grace periods will also be blocked forever. +Of course, one good way to block forever is to deadlock, which can +happen if any operation in a given domain's SRCU read-side critical +section can block waiting, either directly or indirectly, for that domain's +grace period to elapse. +For example, this results in a self-deadlock: + +

+
+ 1 int idx;
+ 2
+ 3 idx = srcu_read_lock(&ss);
+ 4 do_something();
+ 5 synchronize_srcu(&ss);
+ 6 srcu_read_unlock(&ss, idx);
+
+
+ +

+However, if line 5 acquired a mutex that was held across +a synchronize_srcu() for domain ss, +deadlock would still be possible. +Furthermore, if line 5 acquired a mutex that was held across +a synchronize_srcu() for some other domain ss1, +and if an ss1-domain SRCU read-side critical section +acquired another mutex that was held across as ss-domain +synchronize_srcu(), +deadlock would again be possible. +Such a deadlock cycle could extend across an arbitrarily large number +of different SRCU domains. +Again, with great power comes great responsibility. + +

+Unlike the other RCU flavors, SRCU read-side critical sections can +run on idle and even offline CPUs. +This ability requires that srcu_read_lock() and +srcu_read_unlock() contain memory barriers, which means +that SRCU readers will run a bit slower than would RCU readers. +It also motivates the smp_mb__after_srcu_read_unlock() +API, which, in combination with srcu_read_unlock(), +guarantees a full memory barrier. + +

+The +SRCU API +includes +srcu_read_lock(), +srcu_read_unlock(), +srcu_dereference(), +srcu_dereference_check(), +synchronize_srcu(), +synchronize_srcu_expedited(), +call_srcu(), +srcu_barrier(), and +srcu_read_lock_held(). +It also includes +DEFINE_SRCU(), +DEFINE_STATIC_SRCU(), and +init_srcu_struct() +APIs for defining and initializing srcu_struct structures. + +

Tasks RCU

+ +

+Some forms of tracing use “tramopolines” to handle the +binary rewriting required to install different types of probes. +It would be good to be able to free old trampolines, which sounds +like a job for some form of RCU. +However, because it is necessary to be able to install a trace +anywhere in the code, it is not possible to use read-side markers +such as rcu_read_lock() and rcu_read_unlock(). +In addition, it does not work to have these markers in the trampoline +itself, because there would need to be instructions following +rcu_read_unlock(). +Although synchronize_rcu() would guarantee that execution +reached the rcu_read_unlock(), it would not be able to +guarantee that execution had completely left the trampoline. + +

+The solution, in the form of +Tasks RCU, +is to have implicit +read-side critical sections that are delimited by voluntary context +switches, that is, calls to schedule(), +cond_resched_rcu_qs(), and +synchronize_rcu_tasks(). +In addition, transitions to and from userspace execution also delimit +tasks-RCU read-side critical sections. + +

+The tasks-RCU API is quite compact, consisting only of +call_rcu_tasks(), +synchronize_rcu_tasks(), and +rcu_barrier_tasks(). + +

Possible Future Changes

+ +

+One of the tricks that RCU uses to attain update-side scalability is +to increase grace-period latency with increasing numbers of CPUs. +If this becomes a serious problem, it will be necessary to rework the +grace-period state machine so as to avoid the need for the additional +latency. + +

+Expedited grace periods scan the CPUs, so their latency and overhead +increases with increasing numbers of CPUs. +If this becomes a serious problem on large systems, it will be necessary +to do some redesign to avoid this scalability problem. + +

+RCU disables CPU hotplug in a few places, perhaps most notably in the +expedited grace-period and rcu_barrier() operations. +If there is a strong reason to use expedited grace periods in CPU-hotplug +notifiers, it will be necessary to avoid disabling CPU hotplug. +This would introduce some complexity, so there had better be a very +good reason. + +

+The tradeoff between grace-period latency on the one hand and interruptions +of other CPUs on the other hand may need to be re-examined. +The desire is of course for zero grace-period latency as well as zero +interprocessor interrupts undertaken during an expedited grace period +operation. +While this ideal is unlikely to be achievable, it is quite possible that +further improvements can be made. + +

+The multiprocessor implementations of RCU use a combining tree that +groups CPUs so as to reduce lock contention and increase cache locality. +However, this combining tree does not spread its memory across NUMA +nodes nor does it align the CPU groups with hardware features such +as sockets or cores. +Such spreading and alignment is currently believed to be unnecessary +because the hotpath read-side primitives do not access the combining +tree, nor does call_rcu() in the common case. +If you believe that your architecture needs such spreading and alignment, +then your architecture should also benefit from the +rcutree.rcu_fanout_leaf boot parameter, which can be set +to the number of CPUs in a socket, NUMA node, or whatever. +If the number of CPUs is too large, use a fraction of the number of +CPUs. +If the number of CPUs is a large prime number, well, that certainly +is an “interesting” architectural choice! +More flexible arrangements might be considered, but only if +rcutree.rcu_fanout_leaf has proven inadequate, and only +if the inadequacy has been demonstrated by a carefully run and +realistic system-level workload. + +

+Please note that arrangements that require RCU to remap CPU numbers will +require extremely good demonstration of need and full exploration of +alternatives. + +

+There is an embarrassingly large number of flavors of RCU, and this +number has been increasing over time. +Perhaps it will be possible to combine some at some future date. + +

+RCU's various kthreads are reasonably recent additions. +It is quite likely that adjustments will be required to more gracefully +handle extreme loads. +It might also be necessary to be able to relate CPU utilization by +RCU's kthreads and softirq handlers to the code that instigated this +CPU utilization. +For example, RCU callback overhead might be charged back to the +originating call_rcu() instance, though probably not +in production kernels. + +

Summary

+ +

+This document has presented more than two decade's worth of RCU +requirements. +Given that the requirements keep changing, this will not be the last +word on this subject, but at least it serves to get an important +subset of the requirements set forth. + +

+Answers to Quick Quizzes

+ + +

Quick Quiz 1: +Wait a minute! +You said that updaters can make useful forward progress concurrently +with readers, but pre-existing readers will block +synchronize_rcu()!!! +Just who are you trying to fool??? + + +

Answer: +First, if updaters do not wish to be blocked by readers, they can use +call_rcu() or kfree_rcu(), which will +be discussed later. +Second, even when using synchronize_rcu(), the other +update-side code does run concurrently with readers, whether pre-existing +or not. + + +

Back to Quick Quiz 1. + + +

Quick Quiz 2: +Why is the synchronize_rcu() on line 28 needed? + + +

Answer: +Without that extra grace period, memory reordering could result in +do_something_dlm() executing do_something() +concurrently with the last bits of recovery(). + + +

Back to Quick Quiz 2. + + +

Quick Quiz 3: +But rcu_assign_pointer() does nothing to prevent the +two assignments to p->a and p->b +from being reordered. +Can't that also cause problems? + + +

Answer: +No, it cannot. +The readers cannot see either of these two fields until +the assignment to gp, by which time both fields are +fully initialized. +So reordering the assignments +to p->a and p->b cannot possibly +cause any problems. + + +

Back to Quick Quiz 3. + + +

Quick Quiz 4: +Without the rcu_dereference() or the +rcu_access_pointer(), what destructive optimizations +might the compiler make use of? + + +

Answer: +Let's start with what happens to do_something_gp() +if it fails to use rcu_dereference(). +It could reuse a value formerly fetched from this same pointer. +It could also fetch the pointer from gp in a byte-at-a-time +manner, resulting in load tearing, in turn resulting a bytewise +mash-up of two distince pointer values. +It might even use value-speculation optimizations, where it makes a wrong +guess, but by the time it gets around to checking the value, an update +has changed the pointer to match the wrong guess. +Too bad about any dereferences that returned pre-initialization garbage +in the meantime! + +

+For remove_gp_synchronous(), as long as all modifications +to gp are carried out while holding gp_lock, +the above optimizations are harmless. +However, +with CONFIG_SPARSE_RCU_POINTER=y, +sparse will complain if you +define gp with __rcu and then +access it without using +either rcu_access_pointer() or rcu_dereference(). + + +

Back to Quick Quiz 4. + + +

Quick Quiz 5: +Given that multiple CPUs can start RCU read-side critical sections +at any time without any ordering whatsoever, how can RCU possibly tell whether +or not a given RCU read-side critical section starts before a +given instance of synchronize_rcu()? + + +

Answer: +If RCU cannot tell whether or not a given +RCU read-side critical section starts before a +given instance of synchronize_rcu(), +then it must assume that the RCU read-side critical section +started first. +In other words, a given instance of synchronize_rcu() +can avoid waiting on a given RCU read-side critical section only +if it can prove that synchronize_rcu() started first. + + +

Back to Quick Quiz 5. + + +

Quick Quiz 6: +The first and second guarantees require unbelievably strict ordering! +Are all these memory barriers really required? + + +

Answer: +Yes, they really are required. +To see why the first guarantee is required, consider the following +sequence of events: + +

    +
  1. CPU 1: rcu_read_lock() +
  2. CPU 1: q = rcu_dereference(gp); + /* Very likely to return p. */ +
  3. CPU 0: list_del_rcu(p); +
  4. CPU 0: synchronize_rcu() starts. +
  5. CPU 1: do_something_with(q->a); + /* No smp_mb(), so might happen after kfree(). */ +
  6. CPU 1: rcu_read_unlock() +
  7. CPU 0: synchronize_rcu() returns. +
  8. CPU 0: kfree(p); +
+ +

+Therefore, there absolutely must be a full memory barrier between the +end of the RCU read-side critical section and the end of the +grace period. + +

+The sequence of events demonstrating the necessity of the second rule +is roughly similar: + +

    +
  1. CPU 0: list_del_rcu(p); +
  2. CPU 0: synchronize_rcu() starts. +
  3. CPU 1: rcu_read_lock() +
  4. CPU 1: q = rcu_dereference(gp); + /* Might return p if no memory barrier. */ +
  5. CPU 0: synchronize_rcu() returns. +
  6. CPU 0: kfree(p); +
  7. CPU 1: do_something_with(q->a); /* Boom!!! */ +
  8. CPU 1: rcu_read_unlock() +
+ +

+And similarly, without a memory barrier between the beginning of the +grace period and the beginning of the RCU read-side critical section, +CPU 1 might end up accessing the freelist. + +

+The “as if” rule of course applies, so that any implementation +that acts as if the appropriate memory barriers were in place is a +correct implementation. +That said, it is much easier to fool yourself into believing that you have +adhered to the as-if rule than it is to actually adhere to it! + + +

Quick Quiz 7: +But how does the upgrade-to-write operation exclude other readers? + + +

Answer: +It doesn't, just like normal RCU updates, which also do not exclude +RCU readers. + + +

Back to Quick Quiz 7. + + +

Quick Quiz 8: +Can't the compiler also reorder this code? + + +

Answer: +No, the volatile casts in READ_ONCE() and +WRITE_ONCE() prevent the compiler from reordering in +this particular case. + + +

Back to Quick Quiz 8. + + +

Quick Quiz 9: +Suppose that synchronize_rcu() did wait until all readers had completed. +Would the updater be able to rely on this? + + +

Answer: +No. +Even if synchronize_rcu() were to wait until +all readers had completed, a new reader might start immediately after +synchronize_rcu() completed. +Therefore, the code following +synchronize_rcu() cannot rely on there being no readers +in any case. + + +

Back to Quick Quiz 9. + + +

Quick Quiz 10: +How long a sequence of grace periods, each separated by an RCU read-side +critical section, would be required to partition the RCU read-side +critical sections at the beginning and end of the chain? + + +

Answer: +In theory, an infinite number. +In practice, an unknown number that is sensitive to both implementation +details and timing considerations. +Therefore, even in practice, RCU users must abide by the theoretical rather +than the practical answer. + + +

Quick Quiz 11: +What about sleeping locks? + + +

Answer: +These are forbidden within Linux-kernel RCU read-side critical sections +because it is not legal to place a quiescent state (in this case, +voluntary context switch) within an RCU read-side critical section. +However, sleeping locks may be used within userspace RCU read-side critical +sections, and also within Linux-kernel sleepable RCU +(SRCU) +read-side critical sections. +In addition, the -rt patchset turns spinlocks into a sleeping locks so +that the corresponding critical sections can be preempted, which +also means that these sleeplockified spinlocks (but not other sleeping locks!) +may be acquire within -rt-Linux-kernel RCU read-side critical sections. + +

+Note that it is legal for a normal RCU read-side critical section +to conditionally acquire a sleeping locks (as in mutex_trylock()), +but only as long as it does not loop indefinitely attempting to +conditionally acquire that sleeping locks. +The key point is that things like mutex_trylock() +either return with the mutex held, or return an error indication if +the mutex was not immediately available. +Either way, mutex_trylock() returns immediately without sleeping. + + +

Quick Quiz 12: +Why does line 19 use rcu_access_pointer()? +After all, call_rcu() on line 25 stores into the +structure, which would interact badly with concurrent insertions. +Doesn't this mean that rcu_dereference() is required? + + +

Answer: +Presumably the ->gp_lock acquired on line 18 excludes +any changes, including any insertions that rcu_dereference() +would protect against. +Therefore, any insertions will be delayed until after ->gp_lock +is released on line 25, which in turn means that +rcu_access_pointer() suffices. + + +

Quick Quiz 13: +Earlier it was claimed that call_rcu() and +kfree_rcu() allowed updaters to avoid being blocked +by readers. +But how can that be correct, given that the invocation of the callback +and the freeing of the memory (respectively) must still wait for +a grace period to elapse? + + +

Answer: +We could define things this way, but keep in mind that this sort of +definition would say that updates in garbage-collected languages +cannot complete until the next time the garbage collector runs, +which does not seem at all reasonable. +The key point is that in most cases, an updater using either +call_rcu() or kfree_rcu() can proceed to the +next update as soon as it has invoked call_rcu() or +kfree_rcu(), without having to wait for a subsequent +grace period. + + +

Quick Quiz 14: +So what happens with synchronize_rcu() during +scheduler initialization for CONFIG_PREEMPT=n +kernels? + + +

Answer: +In CONFIG_PREEMPT=n kernel, synchronize_rcu() +maps directly to synchronize_sched(). +Therefore, synchronize_rcu() works normally throughout +boot in CONFIG_PREEMPT=n kernels. +However, your code must also work in CONFIG_PREEMPT=y kernels, +so it is still necessary to avoid invoking synchronize_rcu() +during scheduler initialization. + + +

Introduction

+ +

+Read-copy update (RCU) is a synchronization mechanism that is often +used as a replacement for reader-writer locking. +RCU is unusual in that updaters do not block readers, +which means that RCU's read-side primitives can be exceedingly fast +and scalable. +In addition, updaters can make useful forward progress concurrently +with readers. +However, all this concurrency between RCU readers and updaters does raise +the question of exactly what RCU readers are doing, which in turn +raises the question of exactly what RCU's requirements are. + +

+This document therefore summarizes RCU's requirements, and can be thought +of as an informal, high-level specification for RCU. +It is important to understand that RCU's specification is primarily +empirical in nature; +in fact, I learned about many of these requirements the hard way. +This situation might cause some consternation, however, not only +has this learning process been a lot of fun, but it has also been +a great privilege to work with so many people willing to apply +technologies in interesting new ways. + +

+All that aside, here are the categories of currently known RCU requirements: +

  1. + Fundamental Requirements +
  2. Fundamental Non-Requirements +
  3. + Parallelism Facts of Life +
  4. + Quality-of-Implementation Requirements +
  5. + Linux Kernel Complications +

Fundamental Requirements

+ +

+RCU's fundamental requirements are the closest thing RCU has to hard +mathematical requirements. +These are: + +

    +
  1. + Grace-Period Guarantee +
  2. + Publish-Subscribe Guarantee +
  3. + Memory-Barrier Guarantees +
  4. + RCU Primitives Guaranteed to Execute Unconditionally +
  5. + Guaranteed Read-to-Write Upgrade +
+ +

Grace-Period Guarantee

+ +

+RCU's grace-period guarantee is unusual in being premeditated: +Jack Slingwine and I had this guarantee firmly in mind when we started +work on RCU (then called “rclock”) in the early 1990s. +That said, the past two decades of experience with RCU have produced +a much more detailed understanding of this guarantee. + +

+RCU's grace-period guarantee allows updaters to wait for the completion +of all pre-existing RCU read-side critical sections. +An RCU read-side critical section +begins with the marker rcu_read_lock() and ends with +the marker rcu_read_unlock(). +These markers may be nested, and RCU treats a nested set as one +big RCU read-side critical section. +Production-quality implementations of rcu_read_lock() and +rcu_read_unlock() are extremely lightweight, and in +fact have exactly zero overhead in Linux kernels built for production +use with CONFIG_PREEMPT=n. + +

+This guarantee allows ordering to be enforced with extremely low +overhead to readers, for example: + +

+
+ 1 int x, y;
+ 2
+ 3 void thread0(void)
+ 4 {
+ 5   rcu_read_lock();
+ 6   r1 = READ_ONCE(x);
+ 7   r2 = READ_ONCE(y);
+ 8   rcu_read_unlock();
+ 9 }
+10
+11 void thread1(void)
+12 {
+13   WRITE_ONCE(x, 1);
+14   synchronize_rcu();
+15   WRITE_ONCE(y, 1);
+16 }
+
+
+ +

+Because the synchronize_rcu() on line 14 waits for +all pre-existing readers, any instance of thread0() that +loads a value of zero from x must complete before +thread1() stores to y, so that instance must +also load a value of zero from y. +Similarly, any instance of thread0() that loads a value of +one from y must have started after the +synchronize_rcu() started, and must therefore also load +a value of one from x. +Therefore, the outcome: +

+
+(r1 == 0 && r2 == 1)
+
+
+cannot happen. + +

@@QQ@@ +Wait a minute! +You said that updaters can make useful forward progress concurrently +with readers, but pre-existing readers will block +synchronize_rcu()!!! +Just who are you trying to fool??? +

@@QQA@@ +First, if updaters do not wish to be blocked by readers, they can use +call_rcu() or kfree_rcu(), which will +be discussed later. +Second, even when using synchronize_rcu(), the other +update-side code does run concurrently with readers, whether pre-existing +or not. +

@@QQE@@ + +

+This scenario resembles one of the first uses of RCU in +DYNIX/ptx, +which managed a distributed lock manager's transition into +a state suitable for handling recovery from node failure, +more or less as follows: + +

+
+ 1 #define STATE_NORMAL        0
+ 2 #define STATE_WANT_RECOVERY 1
+ 3 #define STATE_RECOVERING    2
+ 4 #define STATE_WANT_NORMAL   3
+ 5
+ 6 int state = STATE_NORMAL;
+ 7
+ 8 void do_something_dlm(void)
+ 9 {
+10   int state_snap;
+11
+12   rcu_read_lock();
+13   state_snap = READ_ONCE(state);
+14   if (state_snap == STATE_NORMAL)
+15     do_something();
+16   else
+17     do_something_carefully();
+18   rcu_read_unlock();
+19 }
+20
+21 void start_recovery(void)
+22 {
+23   WRITE_ONCE(state, STATE_WANT_RECOVERY);
+24   synchronize_rcu();
+25   WRITE_ONCE(state, STATE_RECOVERING);
+26   recovery();
+27   WRITE_ONCE(state, STATE_WANT_NORMAL);
+28   synchronize_rcu();
+29   WRITE_ONCE(state, STATE_NORMAL);
+30 }
+
+
+ +

+The RCU read-side critical section in do_something_dlm() +works with the synchronize_rcu() in start_recovery() +to guarantee that do_something() never runs concurrently +with recovery(), but with little or no synchronization +overhead in do_something_dlm(). + +

@@QQ@@ +Why is the synchronize_rcu() on line 28 needed? +

@@QQA@@ +Without that extra grace period, memory reordering could result in +do_something_dlm() executing do_something() +concurrently with the last bits of recovery(). +

@@QQE@@ + +

+In order to avoid fatal problems such as deadlocks, +an RCU read-side critical section must not contain calls to +synchronize_rcu(). +Similarly, an RCU read-side critical section must not +contain anything that waits, directly or indirectly, on completion of +an invocation of synchronize_rcu(). + +

+Although RCU's grace-period guarantee is useful in and of itself, with +quite a few use cases, +it would be good to be able to use RCU to coordinate read-side +access to linked data structures. +For this, the grace-period guarantee is not sufficient, as can +be seen in function add_gp_buggy() below. +We will look at the reader's code later, but in the meantime, just think of +the reader as locklessly picking up the gp pointer, +and, if the value loaded is non-NULL, locklessly accessing the +->a and ->b fields. + +

+
+ 1 bool add_gp_buggy(int a, int b)
+ 2 {
+ 3   p = kmalloc(sizeof(*p), GFP_KERNEL);
+ 4   if (!p)
+ 5     return -ENOMEM;
+ 6   spin_lock(&gp_lock);
+ 7   if (rcu_access_pointer(gp)) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   p->a = a;
+12   p->b = a;
+13   gp = p; /* ORDERING BUG */
+14   spin_unlock(&gp_lock);
+15   return true;
+16 }
+
+
+ +

+The problem is that both the compiler and weakly ordered CPUs are within +their rights to reorder this code as follows: + +

+
+ 1 bool add_gp_buggy_optimized(int a, int b)
+ 2 {
+ 3   p = kmalloc(sizeof(*p), GFP_KERNEL);
+ 4   if (!p)
+ 5     return -ENOMEM;
+ 6   spin_lock(&gp_lock);
+ 7   if (rcu_access_pointer(gp)) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   gp = p; /* ORDERING BUG */
+12   p->a = a;
+13   p->b = a;
+14   spin_unlock(&gp_lock);
+15   return true;
+16 }
+
+
+ +

+If an RCU reader fetches gp just after +add_gp_buggy_optimized executes line 11, +it will see garbage in the ->a and ->b +fields. +And this is but one of many ways in which compiler and hardware optimizations +could cause trouble. +Therefore, we clearly need some way to prevent the compiler and the CPU from +reordering in this manner, which brings us to the publish-subscribe +guarantee discussed in the next section. + +

Publish/Subscribe Guarantee

+ +

+RCU's publish-subscribe guarantee allows data to be inserted +into a linked data structure without disrupting RCU readers. +The updater uses rcu_assign_pointer() to insert the +new data, and readers use rcu_dereference() to +access data, whether new or old. +The following shows an example of insertion: + +

+
+ 1 bool add_gp(int a, int b)
+ 2 {
+ 3   p = kmalloc(sizeof(*p), GFP_KERNEL);
+ 4   if (!p)
+ 5     return -ENOMEM;
+ 6   spin_lock(&gp_lock);
+ 7   if (rcu_access_pointer(gp)) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   p->a = a;
+12   p->b = a;
+13   rcu_assign_pointer(gp, p);
+14   spin_unlock(&gp_lock);
+15   return true;
+16 }
+
+
+ +

+The rcu_assign_pointer() on line 13 is conceptually +equivalent to a simple assignment statement, but also guarantees +that its assignment will +happen after the two assignments in lines 11 and 12, +similar to the C11 memory_order_release store operation. +It also prevents any number of “interesting” compiler +optimizations, for example, the use of gp as a scratch +location immediately preceding the assignment. + +

@@QQ@@ +But rcu_assign_pointer() does nothing to prevent the +two assignments to p->a and p->b +from being reordered. +Can't that also cause problems? +

@@QQA@@ +No, it cannot. +The readers cannot see either of these two fields until +the assignment to gp, by which time both fields are +fully initialized. +So reordering the assignments +to p->a and p->b cannot possibly +cause any problems. +

@@QQE@@ + +

+It is tempting to assume that the reader need not do anything special +to control its accesses to the RCU-protected data, +as shown in do_something_gp_buggy() below: + +

+
+ 1 bool do_something_gp_buggy(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   p = gp;  /* OPTIMIZATIONS GALORE!!! */
+ 5   if (p) {
+ 6     do_something(p->a, p->b);
+ 7     rcu_read_unlock();
+ 8     return true;
+ 9   }
+10   rcu_read_unlock();
+11   return false;
+12 }
+
+
+ +

+However, this temptation must be resisted because there are a +surprisingly large number of ways that the compiler +(to say nothing of +DEC Alpha CPUs) +can trip this code up. +For but one example, if the compiler were short of registers, it +might choose to refetch from gp rather than keeping +a separate copy in p as follows: + +

+
+ 1 bool do_something_gp_buggy_optimized(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   if (gp) { /* OPTIMIZATIONS GALORE!!! */
+ 5     do_something(gp->a, gp->b);
+ 6     rcu_read_unlock();
+ 7     return true;
+ 8   }
+ 9   rcu_read_unlock();
+10   return false;
+11 }
+
+
+ +

+If this function ran concurrently with a series of updates that +replaced the current structure with a new one, +the fetches of gp->a +and gp->b might well come from two different structures, +which could cause serious confusion. +To prevent this (and much else besides), do_something_gp() uses +rcu_dereference() to fetch from gp: + +

+
+ 1 bool do_something_gp(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   p = rcu_dereference(gp);
+ 5   if (p) {
+ 6     do_something(p->a, p->b);
+ 7     rcu_read_unlock();
+ 8     return true;
+ 9   }
+10   rcu_read_unlock();
+11   return false;
+12 }
+
+
+ +

+The rcu_dereference() uses volatile casts and (for DEC Alpha) +memory barriers in the Linux kernel. +Should a +high-quality implementation of C11 memory_order_consume [PDF] +ever appear, then rcu_dereference() could be implemented +as a memory_order_consume load. +Regardless of the exact implementation, a pointer fetched by +rcu_dereference() may not be used outside of the +outermost RCU read-side critical section containing that +rcu_dereference(), unless protection of +the corresponding data element has been passed from RCU to some +other synchronization mechanism, most commonly locking or +reference counting. + +

+In short, updaters use rcu_assign_pointer() and readers +use rcu_dereference(), and these two RCU API elements +work together to ensure that readers have a consistent view of +newly added data elements. + +

+Of course, it is also necessary to remove elements from RCU-protected +data structures, for example, using the following process: + +

    +
  1. Remove the data element from the enclosing structure. +
  2. Wait for all pre-existing RCU read-side critical sections + to complete (because only pre-existing readers can possibly have + a reference to the newly removed data element). +
  3. At this point, only the updater has a reference to the + newly removed data element, so it can safely reclaim + the data element, for example, by passing it to kfree(). +
+ +This process is implemented by remove_gp_synchronous(): + +
+
+ 1 bool remove_gp_synchronous(void)
+ 2 {
+ 3   struct foo *p;
+ 4
+ 5   spin_lock(&gp_lock);
+ 6   p = rcu_access_pointer(gp);
+ 7   if (!p) {
+ 8     spin_unlock(&gp_lock);
+ 9     return false;
+10   }
+11   rcu_assign_pointer(gp, NULL);
+12   spin_unlock(&gp_lock);
+13   synchronize_rcu();
+14   kfree(p);
+15   return true;
+16 }
+
+
+ +

+This function is straightforward, with line 13 waiting for a grace +period before line 14 frees the old data element. +This waiting ensures that readers will reach line 7 of +do_something_gp() before the data element referenced by +p is freed. +The rcu_access_pointer() on line 6 is similar to +rcu_dereference(), except that: + +

    +
  1. The value returned by rcu_access_pointer() + cannot be dereferenced. + If you want to access the value pointed to as well as + the pointer itself, use rcu_dereference() + instead of rcu_access_pointer(). +
  2. The call to rcu_access_pointer() need not be + protected. + In contrast, rcu_dereference() must either be + within an RCU read-side critical section or in a code + segment where the pointer cannot change, for example, in + code protected by the corresponding update-side lock. +
+ +

@@QQ@@ +Without the rcu_dereference() or the +rcu_access_pointer(), what destructive optimizations +might the compiler make use of? +

@@QQA@@ +Let's start with what happens to do_something_gp() +if it fails to use rcu_dereference(). +It could reuse a value formerly fetched from this same pointer. +It could also fetch the pointer from gp in a byte-at-a-time +manner, resulting in load tearing, in turn resulting a bytewise +mash-up of two distince pointer values. +It might even use value-speculation optimizations, where it makes a wrong +guess, but by the time it gets around to checking the value, an update +has changed the pointer to match the wrong guess. +Too bad about any dereferences that returned pre-initialization garbage +in the meantime! + +

+For remove_gp_synchronous(), as long as all modifications +to gp are carried out while holding gp_lock, +the above optimizations are harmless. +However, +with CONFIG_SPARSE_RCU_POINTER=y, +sparse will complain if you +define gp with __rcu and then +access it without using +either rcu_access_pointer() or rcu_dereference(). +

@@QQE@@ + +

+In short, RCU's publish-subscribe guarantee is provided by the combination +of rcu_assign_pointer() and rcu_dereference(). +This guarantee allows data elements to be safely added to RCU-protected +linked data structures without disrupting RCU readers. +This guarantee can be used in combination with the grace-period +guarantee to also allow data elements to be removed from RCU-protected +linked data structures, again without disrupting RCU readers. + +

+This guarantee was only partially premeditated. +DYNIX/ptx used an explicit memory barrier for publication, but had nothing +resembling rcu_dereference() for subscription, nor did it +have anything resembling the smp_read_barrier_depends() +that was later subsumed into rcu_dereference(). +The need for these operations made itself known quite suddenly at a +late-1990s meeting with the DEC Alpha architects, back in the days when +DEC was still a free-standing company. +It took the Alpha architects a good hour to convince me that any sort +of barrier would ever be needed, and it then took me a good two hours +to convince them that their documentation did not make this point clear. +More recent work with the C and C++ standards committees have provided +much education on tricks and traps from the compiler. +In short, compilers were much less tricky in the early 1990s, but in +2015, don't even think about omitting rcu_dereference()! + +

Memory-Barrier Guarantees

+ +

+The previous section's simple linked-data-structure scenario clearly +demonstrates the need for RCU's stringent memory-ordering guarantees on +systems with more than one CPU: + +

    +
  1. Each CPU that has an RCU read-side critical section that + begins before synchronize_rcu() starts is + guaranteed to execute a full memory barrier between the time + that the RCU read-side critical section ends and the time that + synchronize_rcu() returns. + Without this guarantee, a pre-existing RCU read-side critical section + might hold a reference to the newly removed struct foo + after the kfree() on line 14 of + remove_gp_synchronous(). +
  2. Each CPU that has an RCU read-side critical section that ends + after synchronize_rcu() returns is guaranteed + to execute a full memory barrier between the time that + synchronize_rcu() begins and the time that the RCU + read-side critical section begins. + Without this guarantee, a later RCU read-side critical section + running after the kfree() on line 14 of + remove_gp_synchronous() might + later run do_something_gp() and find the + newly deleted struct foo. +
  3. If the task invoking synchronize_rcu() remains + on a given CPU, then that CPU is guaranteed to execute a full + memory barrier sometime during the execution of + synchronize_rcu(). + This guarantee ensures that the kfree() on + line 14 of remove_gp_synchronous() really does + execute after the removal on line 11. +
  4. If the task invoking synchronize_rcu() migrates + among a group of CPUs during that invocation, then each of the + CPUs in that group is guaranteed to execute a full memory barrier + sometime during the execution of synchronize_rcu(). + This guarantee also ensures that the kfree() on + line 14 of remove_gp_synchronous() really does + execute after the removal on + line 11, but also in the case where the thread executing the + synchronize_rcu() migrates in the meantime. +
+ +

@@QQ@@ +Given that multiple CPUs can start RCU read-side critical sections +at any time without any ordering whatsoever, how can RCU possibly tell whether +or not a given RCU read-side critical section starts before a +given instance of synchronize_rcu()? +

@@QQA@@ +If RCU cannot tell whether or not a given +RCU read-side critical section starts before a +given instance of synchronize_rcu(), +then it must assume that the RCU read-side critical section +started first. +In other words, a given instance of synchronize_rcu() +can avoid waiting on a given RCU read-side critical section only +if it can prove that synchronize_rcu() started first. +

@@QQE@@ + +

@@QQ@@ +The first and second guarantees require unbelievably strict ordering! +Are all these memory barriers really required? +

@@QQA@@ +Yes, they really are required. +To see why the first guarantee is required, consider the following +sequence of events: + +

    +
  1. CPU 1: rcu_read_lock() +
  2. CPU 1: q = rcu_dereference(gp); + /* Very likely to return p. */ +
  3. CPU 0: list_del_rcu(p); +
  4. CPU 0: synchronize_rcu() starts. +
  5. CPU 1: do_something_with(q->a); + /* No smp_mb(), so might happen after kfree(). */ +
  6. CPU 1: rcu_read_unlock() +
  7. CPU 0: synchronize_rcu() returns. +
  8. CPU 0: kfree(p); +
+ +

+Therefore, there absolutely must be a full memory barrier between the +end of the RCU read-side critical section and the end of the +grace period. + +

+The sequence of events demonstrating the necessity of the second rule +is roughly similar: + +

    +
  1. CPU 0: list_del_rcu(p); +
  2. CPU 0: synchronize_rcu() starts. +
  3. CPU 1: rcu_read_lock() +
  4. CPU 1: q = rcu_dereference(gp); + /* Might return p if no memory barrier. */ +
  5. CPU 0: synchronize_rcu() returns. +
  6. CPU 0: kfree(p); +
  7. CPU 1: do_something_with(q->a); /* Boom!!! */ +
  8. CPU 1: rcu_read_unlock() +
+ +

+And similarly, without a memory barrier between the beginning of the +grace period and the beginning of the RCU read-side critical section, +CPU 1 might end up accessing the freelist. + +

+The “as if” rule of course applies, so that any implementation +that acts as if the appropriate memory barriers were in place is a +correct implementation. +That said, it is much easier to fool yourself into believing that you have +adhered to the as-if rule than it is to actually adhere to it! +

@@QQE@@ + +

+Note that these memory-barrier requirements do not replace the fundamental +RCU requirement that a grace period wait for all pre-existing readers. +On the contrary, the memory barriers called out in this section must operate in +such a way as to enforce this fundamental requirement. +Of course, different implementations enforce this requirement in different +ways, but enforce it they must. + +

RCU Primitives Guaranteed to Execute Unconditionally

+ +

+The common-case RCU primitives are unconditional. +They are invoked, they do their job, and they return, with no possibility +of error, and no need to retry. +This is a key RCU design philosophy. + +

+However, this philosophy is pragmatic rather than pigheaded. +If someone comes up with a good justification for a particular conditional +RCU primitive, it might well be implemented and added. +After all, this guarantee was reverse-engineered, not premeditated. +The unconditional nature of the RCU primitives was initially an +accident of implementation, and later experience with synchronization +primitives with conditional primitives caused me to elevate this +accident to a guarantee. +Therefore, the justification for adding a conditional primitive to +RCU would need to be based on detailed and compelling use cases. + +

Guaranteed Read-to-Write Upgrade

+ +

+As far as RCU is concerned, it is always possible to carry out an +update within an RCU read-side critical section. +For example, that RCU read-side critical section might search for +a given data element, and then might acquire the update-side +spinlock in order to update that element, all while remaining +in that RCU read-side critical section. +Of course, it is necessary to exit the RCU read-side critical section +before invoking synchronize_rcu(), however, this +inconvenience can be avoided through use of the +call_rcu() and kfree_rcu() API members +described later in this document. + +

+RCU provides extremely lightweight readers, and its read-side guarantees, +though quite useful, are correspondingly lightweight. +It is therefore all too easy to assume that RCU is guaranteeing more +than it really is. +Of course, the list of things that RCU does not guarantee is infinitely +long, however, the following sections list a few non-guarantees that +have caused confusion. +Except where otherwise noted, these non-guarantees were premeditated. + +

Readers Impose Minimal Ordering

+ +

+Reader-side markers such as rcu_read_lock() and +rcu_read_unlock() provide absolutely no ordering guarantees +except through their interaction with the grace-period APIs such as +synchronize_rcu(). +To see this, consider the following pair of threads: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(x, 1);
+ 5   rcu_read_unlock();
+ 6   rcu_read_lock();
+ 7   WRITE_ONCE(y, 1);
+ 8   rcu_read_unlock();
+ 9 }
+10
+11 void thread1(void)
+12 {
+13   rcu_read_lock();
+14   r1 = READ_ONCE(y);
+15   rcu_read_unlock();
+16   rcu_read_lock();
+17   r2 = READ_ONCE(x);
+18   rcu_read_unlock();
+19 }
+
+
+ +

+After thread0() and thread1() execute +concurrently, it is quite possible to have + +

+
+(r1 == 1 && r2 == 0)
+
+
+ +(that is, y appears to have been assigned before x), +which would not be possible if rcu_read_lock() and +rcu_read_unlock() had much in the way of ordering +properties. +But they do not, so the CPU is within its rights +to do significant reordering. +This is by design: Any significant ordering constraints would slow down +these fast-path APIs. + +

@@QQ@@ +Can't the compiler also reorder this code? +

@@QQA@@ +No, the volatile casts in READ_ONCE() and +WRITE_ONCE() prevent the compiler from reordering in +this particular case. +

Readers Do Not Exclude Updaters

+ +

+Neither rcu_read_lock() nor rcu_read_unlock() +exclude updates. +All they do is to prevent grace periods from ending. +The following example illustrates this: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   r1 = READ_ONCE(y);
+ 5   if (r1) {
+ 6     do_something_with_nonzero_x();

+ 8     WARN_ON(!r2); /* BUG!!! */
+ 9   }
+10   rcu_read_unlock();

+12
+13 void thread1(void)
+14 {
+15   spin_lock(&my_lock);
+16   WRITE_ONCE(x, 1);
+17   WRITE_ONCE(y, 1);
+18   spin_unlock(&my_lock);
+19 }
+
+
+ +

+If the thread0() function's rcu_read_lock() +excluded the thread1() function's update, +the WARN_ON() could never fire. +But the fact is that rcu_read_lock() does not exclude +much of anything aside from subsequent grace periods, of which +thread1() has none, so the +WARN_ON() can and does fire. + +

Updaters Only Wait For Old Readers

+ +

+It might be tempting to assume that after synchronize_rcu() +completes, there are no readers executing. +This temptation must be avoided because +new readers can start immediately after synchronize_rcu() +starts, and synchronize_rcu() is under no +obligation to wait for these new readers. + +

@@QQ@@ +Suppose that synchronize_rcu() did wait until all readers had completed. +Would the updater be able to rely on this? +

+Grace Periods Don't Partition Read-Side Critical Sections

+ +

+It is tempting to assume that if any part of one RCU read-side critical +section precedes a given grace period, and if any part of another RCU +read-side critical section follows that same grace period, then all of +the first RCU read-side critical section must precede all of the second. +However, this just isn't the case: A single grace period does not +partition the set of RCU read-side critical sections. +An example of this situation can be illustrated as follows, where +x, y, and z are initially all zero: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(a, 1);
+ 5   WRITE_ONCE(b, 1);
+ 6   rcu_read_unlock();
+ 7 }
+ 8
+ 9 void thread1(void)
+10 {
+11   r1 = READ_ONCE(a);
+12   synchronize_rcu();
+13   WRITE_ONCE(c, 1);
+14 }
+15
+16 void thread2(void)
+17 {

+19   r2 = READ_ONCE(b);
+20   r3 = READ_ONCE(c);
+21   rcu_read_unlock();
+22 }
+
+
+ +

+It turns out that the outcome: + +

+
+(r1 == 1 && r2 == 0 && r3 == 1)
+
+
+ +is entirely possible. +The following figure show how this can happen, with each circled +QS indicating the point at which RCU recorded a +quiescent state for each thread, that is, a state in which +RCU knows that the thread cannot be in the midst of an RCU read-side +critical section that started before the current grace period: + +

GPpartitionReaders1.svg

+ +

+If it is necessary to partition RCU read-side critical sections in this +manner, it is necessary to use two grace periods, where the first +grace period is known to end before the second grace period starts: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(a, 1);
+ 5   WRITE_ONCE(b, 1);

+26   r3 = READ_ONCE(b);
+27   r4 = READ_ONCE(d);
+28   rcu_read_unlock();
+29 }
+
+
+ +

+Here, if (r1 == 1), then +thread0()'s write to b must happen +before the end of thread1()'s grace period. +If in addition (r4 == 1), then +thread3()'s read from b must happen +after the beginning of thread2()'s grace period. +If it is also the case that (r2 == 1), then the +end of thread1()'s grace period must precede the +beginning of thread2()'s grace period. +This mean that the two RCU read-side critical sections cannot overlap, +guaranteeing that (r3 == 1). +As a result, the outcome: + +

+
+(r1 == 1 && r2 == 1 && r3 == 0 && r4 == 1)
+
+
+ +cannot happen. + +

+This non-requirement was also non-premeditated, but became apparent +when studying RCU's interaction with memory ordering. + +

+Read-Side Critical Sections Don't Partition Grace Periods

+ +

+It is also tempting to assume that if an RCU read-side critical section +happens between a pair of grace periods, then those grace periods cannot +overlap. +However, this temptation leads nowhere good, as can be illustrated by +the following, with all variables initially zero: + +

+
+ 1 void thread0(void)
+ 2 {
+ 3   rcu_read_lock();
+ 4   WRITE_ONCE(a, 1);
+ 5   WRITE_ONCE(b, 1);

+ 9 void thread1(void)
+10 {
+11   r1 = READ_ONCE(a);
+12   synchronize_rcu();
+13   WRITE_ONCE(c, 1);
+14 }
+15
+16 void thread2(void)
+17 {
+18   rcu_read_lock();
+19   WRITE_ONCE(d, 1);
+20   r2 = READ_ONCE(c);

+24 void thread3(void)
+25 {
+26   r3 = READ_ONCE(d);

+34   r4 = READ_ONCE(b);
+35   r5 = READ_ONCE(e);
+36   rcu_read_unlock();
+37 }
+
+
+ +

+In this case, the outcome: + +

+
+(r1 == 1 && r2 == 1 && r3 == 1 && r4 == 0 && r5 == 1)
+
+
+ +is entirely possible, as illustrated below: + +

+ +

+Again, an RCU read-side critical section can overlap almost all of a +given grace period, just so long as it does not overlap the entire +grace period. +As a result, an RCU read-side critical section cannot partition a pair +of RCU grace periods. + +

+Disabling Preemption Does Not Block Grace Periods

+ +

+There was a time when disabling preemption on any given CPU would block +subsequent grace periods. +However, this was an accident of implementation and is not a requirement. +And in the current Linux-kernel implementation, disabling preemption +on a given CPU in fact does not block grace periods, as Oleg Nesterov +demonstrated. + +

+If you need a preempt-disable region to block grace periods, you need to add +rcu_read_lock() and rcu_read_unlock(), for example +as follows: + +

+
+ 1 preempt_disable();
+ 2 rcu_read_lock();
+ 3 do_something();
+ 4 rcu_read_unlock();
+ 5 preempt_enable();
+ 6
+ 7 /* Spinlocks implicitly disable preemption. */
+ 8 spin_lock(&mylock);
+ 9 rcu_read_lock();
+10 do_something();
+11 rcu_read_unlock();
+12 spin_unlock(&mylock);
+
+
+ +

+In theory, you could enter the RCU read-side critical section first, +but it is more efficient to keep the entire RCU read-side critical +section contained in the preempt-disable region as shown above. +Of course, RCU read-side critical sections that extend outside of +preempt-disable regions will work correctly, but such critical sections +can be preempted, which forces rcu_read_unlock() to do +more work. +And no, this is not an invitation to enclose all of your RCU +read-side critical sections within preempt-disable regions, because +doing so would degrade real-time response. + +

+This non-requirement appeared with preemptible RCU. +If you need a grace period that waits on non-preemptible code regions, use +RCU-sched. + +

Parallelism Facts of Life

+ +

+These parallelism facts of life are by no means specific to RCU, but +the RCU implementation must abide by them. +They therefore bear repeating: + +

    +
  1. Any CPU or task may be delayed at any time, + and any attempts to avoid these delays by disabling + preemption, interrupts, or whatever are completely futile. + This is most obvious in preemptible user-level + environments and in virtualized environments (where + a given guest OS's VCPUs can be preempted at any time by + the underlying hypervisor), but can also happen in bare-metal + environments due to ECC errors, NMIs, and other hardware + events. + Although a delay of more than about 20 seconds can result + in splats, the RCU implementation is obligated to use + algorithms that can tolerate extremely long delays, but where + “extremely long” is not long enough to allow + wrap-around when incrementing a 64-bit counter. +
  2. Both the compiler and the CPU can reorder memory accesses. + Where it matters, RCU must use compiler directives and + memory-barrier instructions to preserve ordering. +
  3. Conflicting writes to memory locations in any given cache line + will result in expensive cache misses. + Greater numbers of concurrent writes and more-frequent + concurrent writes will result in more dramatic slowdowns. + RCU is therefore obligated to use algorithms that have + sufficient locality to avoid significant performance and + scalability problems. +
  4. As a rough rule of thumb, only one CPU's worth of processing + may be carried out under the protection of any given exclusive + lock. + RCU must therefore use scalable locking designs. +
  5. Counters are finite, especially on 32-bit systems. + RCU's use of counters must therefore tolerate counter wrap, + or be designed such that counter wrap would take way more + time than a single system is likely to run. + An uptime of ten years is quite possible, a runtime + of a century much less so. + As an example of the latter, RCU's dyntick-idle nesting counter + allows 54 bits for interrupt nesting level (this counter + is 64 bits even on a 32-bit system). + Overflowing this counter requires 254 + half-interrupts on a given CPU without that CPU ever going idle. + If a half-interrupt happened every microsecond, it would take + 570 years of runtime to overflow this counter, which is currently + believed to be an acceptably long time. +
  6. Linux systems can have thousands of CPUs running a single + Linux kernel in a single shared-memory environment. + RCU must therefore pay close attention to high-end scalability. +
+ +

+This last parallelism fact of life means that RCU must pay special +attention to the preceding facts of life. +The idea that Linux might scale to systems with thousands of CPUs would +have been met with some skepticism in the 1990s, but these requirements +would have otherwise have been unsurprising, even in the early 1990s. + +

Quality-of-Implementation Requirements

+ +

+These sections list quality-of-implementation requirements. +Although an RCU implementation that ignores these requirements could +still be used, it would likely be subject to limitations that would +make it inappropriate for industrial-strength production use. +Classes of quality-of-implementation requirements are as follows: + +

    +
  1. Specialization +
  2. Performance and Scalability +
  3. Composability +
  4. Corner Cases +
+ +

+These classes is covered in the following sections. + +

Specialization

+ +

+RCU is and always has been intended primarily for read-mostly situations, as +illustrated by the following figure. +This means that RCU's read-side primitives are optimized, often at the +expense of its update-side primitives. + +

RCUApplicability.svg

+ +

+This focus on read-mostly situations means that RCU must interoperate +with other synchronization primitives. +For example, the add_gp() and remove_gp_synchronous() +examples discussed earlier use RCU to protect readers and locking to +coordinate updaters. +However, the need extends much farther, requiring that a variety of +synchronization primitives be legal within RCU read-side critical sections, +including spinlocks, sequence locks, atomic operations, reference +counters, and memory barriers. + +

@@QQ@@ +What about sleeping locks? +

@@QQA@@ +These are forbidden within Linux-kernel RCU read-side critical sections +because it is not legal to place a quiescent state (in this case, +voluntary context switch) within an RCU read-side critical section. +However, sleeping locks may be used within userspace RCU read-side critical +sections, and also within Linux-kernel sleepable RCU +(SRCU) +read-side critical sections. +In addition, the -rt patchset turns spinlocks into a sleeping locks so +that the corresponding critical sections can be preempted, which +also means that these sleeplockified spinlocks (but not other sleeping locks!) +may be acquire within -rt-Linux-kernel RCU read-side critical sections. + +

+Note that it is legal for a normal RCU read-side critical section +to conditionally acquire a sleeping locks (as in mutex_trylock()), +but only as long as it does not loop indefinitely attempting to +conditionally acquire that sleeping locks. +The key point is that things like mutex_trylock() +either return with the mutex held, or return an error indication if +the mutex was not immediately available. +Either way, mutex_trylock() returns immediately without sleeping. +

@@QQE@@ + +

+It often comes as a surprise that many algorithms do not require a +consistent view of data, but many can function in that mode, +with network routing being the poster child. +Internet routing algorithms take significant time to propagate +updates, so that by the time an update arrives at a given system, +that system has been sending network traffic the wrong way for +a considerable length of time. +Having a few threads continue to send traffic the wrong way for a +few more milliseconds is clearly not a problem: In the worst case, +TCP retransmissions will eventually get the data where it needs to go. +In general, when tracking the state of the universe outside of the +computer, some level of inconsistency must be tolerated due to +speed-of-light delays if nothing else. + +

+Furthermore, uncertainty about external state is inherent in many cases. +For example, a pair of veternarians might use heartbeat to determine +whether or not a given cat was alive. +But how long should they wait after the last heartbeat to decide that +the cat is in fact dead? +Waiting less than 400 milliseconds makes no sense because this would +mean that a relaxed cat would be considered to cycle between death +and life more than 100 times per minute. +Moreover, just as with human beings, a cat's heart might stop for +some period of time, so the exact wait period is a judgment call. +One of our pair of veternarians might wait 30 seconds before pronouncing +the cat dead, while the other might insist on waiting a full minute. +The two veternarians would then disagree on the state of the cat during +the final 30 seconds of the minute following the last heartbeat, as +fancifully illustrated below: + +

2013-08-is-it-dead.png

+ +

+Interestingly enough, this same situation applies to hardware. +When push comes to shove, how do we tell whether or not some +external server has failed? +We send messages to it periodically, and declare it failed if we +don't receive a response within a given period of time. +Policy decisions can usually tolerate short +periods of inconsistency. +The policy was decided some time ago, and is only now being put into +effect, so a few milliseconds of delay is normally inconsequential. + +

+However, there are algorithms that absolutely must see consistent data. +For example, the translation between a user-level SystemV semaphore +ID to the corresponding in-kernel data structure is protected by RCU, +but it is absolutely forbidden to update a semaphore that has just been +removed. +In the Linux kernel, this need for consistency is accommodated by acquiring +spinlocks located in the in-kernel data structure from within +the RCU read-side critical section, and this is indicated by the +green box in the figure above. +Many other techniques may be used, and are in fact used within the +Linux kernel. + +

+In short, RCU is not required to maintain consistency, and other +mechanisms may be used in concert with RCU when consistency is required. +RCU's specialization allows it to do its job extremely well, and its +ability to interoperate with other synchronization mechanisms allows +the right mix of synchronization tools to be used for a given job. + +

Performance and Scalability

+ +

+Energy efficiency is a critical component of performance today, +and Linux-kernel RCU implementations must therefore avoid unnecessarily +awakening idle CPUs. +I cannot claim that this requirement was premeditated. +In fact, I learned of it during a telephone conversation in which I +was given “frank and open” feedback on the importance +of energy efficiency in battery-powered systems and on specific +energy-efficiency shortcomings of the Linux-kernel RCU implementation. +In my experience, the battery-powered embedded community will consider +any unnecessary wakeups to be extremely unfriendly acts. +So much so that mere Linux-kernel-mailing-list posts are +insufficient to vent their ire. + +

+Memory consumption is not particularly important for in most +situations, and has become decreasingly +so as memory sizes have expanded and memory +costs have plummeted. +However, as I learned from Matt Mackall's +bloatwatch +efforts, memory footprint is critically important on single-CPU systems with +non-preemptible (CONFIG_PREEMPT=n) kernels, and thus +tiny RCU +was born. +Josh Triplett has since taken over the small-memory banner with his +Linux kernel tinification +project, which resulted in +SRCU +becoming optional for those kernels not needing it. + +

+The remaining performance requirements are, for the most part, +unsurprising. +For example, in keeping with RCU's read-side specialization, +rcu_dereference() should have negligible overhead (for +example, suppression of a few minor compiler optimizations). +Similarly, in non-preemptible environments, rcu_read_lock() and +rcu_read_unlock() should have exactly zero overhead. + +

+In preemptible environments, in the case where the RCU read-side +critical section was not preempted (as will be the case for the +highest-priority real-time process), rcu_read_lock() and +rcu_read_unlock() should have minimal overhead. +In particular, they should not contain atomic read-modify-write +operations, memory-barrier instructions, preemption disabling, +interrupt disabling, or backwards branches. +However, in the case where the RCU read-side critical section was preempted, +rcu_read_unlock() may acquire spinlocks and disable interrupts. +This is why it is better to nest an RCU read-side critical section +within a preempt-disable region than vice versa, at least in cases +where that critical section is short enough to avoid unduly degrading +real-time latencies. + +

+The synchronize_rcu() grace-period-wait primitive is +optimized for throughput. +It may therefore incur several milliseconds of latency in addition to +the duration of the longest RCU read-side critical section. +On the other hand, multiple concurrent invocations of +synchronize_rcu() are required to use batching optimizations +so that they can be satisfied by a single underlying grace-period-wait +operation. +For example, in the Linux kernel, it is not unusual for a single +grace-period-wait operation to serve more than +1,000 separate invocations +of synchronize_rcu(), thus amortizing the per-invocation +overhead down to nearly zero. +However, the grace-period optimization is also required to avoid +measurable degradation of real-time scheduling and interrupt latencies. + +

+In some cases, the multi-millisecond synchronize_rcu() +latencies are unacceptable. +In these cases, synchronize_rcu_expedited() may be used +instead, reducing the grace-period latency down to a few tens of +microseconds on small systems, at least in cases where the RCU read-side +critical sections are short. +There are currently no special latency requirements for +synchronize_rcu_expedited() on large systems, but, +consistent with the empirical nature of the RCU specification, +that is subject to change. +However, there most definitely are scalability requirements: +A storm of synchronize_rcu_expedited() invocations on 4096 +CPUs should at least make reasonable forward progress. +In return for its shorter latencies, synchronize_rcu_expedited() +is permitted to impose modest degradation of real-time latency +on non-idle online CPUs. +That said, it will likely be necessary to take further steps to reduce this +degradation, hopefully to roughly that of a scheduling-clock interrupt. + +

+There are a number of situations where even +synchronize_rcu_expedited()'s reduced grace-period +latency is unacceptable. +In these situations, the asynchronous call_rcu() can be +used in place of synchronize_rcu() as follows: + +

+
+ 1 struct foo {
+ 2   int a;
+ 3   int b;
+ 4   struct rcu_head rh;
+ 5 };

+A definition of struct foo is finally needed, and appears +on lines 1-5. +The function remove_gp_cb() is passed to call_rcu() +on line 25, and will be invoked after the end of a subsequent +grace period. +This gets the same effect as remove_gp_synchronous(), +but without forcing the updater to wait for a grace period to elapse. +The call_rcu() function may be used in a number of +situations where neither synchronize_rcu() nor +synchronize_rcu_expedited() would be legal, +including within preempt-disable code, local_bh_disable() code, +interrupt-disable code, and interrupt handlers. +However, even call_rcu() is illegal within NMI handlers. +The callback function (remove_gp_cb() in this case) will be +executed within softirq (software interrupt) environment within the +Linux kernel, +either within a real softirq handler or under the protection +of local_bh_disable(). +In both the Linux kernel and in userspace, it is bad practice to +write an RCU callback function that takes too long. +Long-running operations should be relegated to separate threads or +(in the Linux kernel) workqueues. + +

+RCU thus provides a range of tools to allow updaters to strike the +required tradeoff between latency, flexibility and CPU overhead. + +

Composability

+ +

+Composability has received much attention in recent years, perhaps in part +due to the collision of multicore hardware with object-oriented techniques +designed in single-threaded environments for single-threaded use. +And in theory, RCU read-side critical sections may be composed, and in +fact may be nested arbitrarily deeply. +In practice, as with all real-world implementations of composable +constructs, there are limitations. + +

+Implementations of RCU for which rcu_read_lock() +and rcu_read_unlock() generate no code, such as +Linux-kernel RCU when CONFIG_PREEMPT=n, can be +nested arbitrarily deeply. +After all, there is no overhead. +Except that if all these instances of rcu_read_lock() +and rcu_read_unlock() are visible to the compiler, +compilation will eventually fail due to exhausting memory, +mass storage, or user patience, whichever comes first. +If the nesting is not visible to the compiler, as is the case with +mutually recursive functions each in its own translation unit, +stack overflow will result. +If the nesting takes the form of loops, either the control variable +will overflow or (in the Linux kernel) you will get an RCU CPU stall warning. +Nevertheless, this class of RCU implementations is one +of the most composable constructs in existence. + +

+RCU implementations that explicitly track nesting depth +are limited by the nesting-depth counter. +For example, the Linux kernel's preemptible RCU limits nesting to +INT_MAX. +This should suffice for almost all practical purposes. +That said, a consecutive pair of RCU read-side critical sections +between which there is an operation that waits for a grace period +cannot be enclosed in another RCU read-side critical section. +This is because it is not legal to wait for a grace period within +an RCU read-side critical section: To do so would result either +in deadlock or +in RCU implicitly splitting the enclosing RCU read-side critical +section, neither of which is conducive to a long-lived and prosperous +kernel. + +

+It is worth noting that RCU is not alone in limiting composability. +For example, many transactional-memory implementations prohibit +composing a pair of transactions separated by an irrevocable +operation (for example, a network receive operation). +For another example, lock-based critical sections can be composed +surprisingly freely, but only if deadlock is avoided. + +

+In short, although RCU read-side critical sections are highly composable, +care is required in some situations, just as is the case for any other +composable synchronization mechanism. + +

Corner Cases

+ +

+A given RCU workload might have an endless and intense stream of +RCU read-side critical sections, perhaps even so intense that there +was never a point in time during which there was not at least one +RCU read-side critical section in flight. +RCU cannot allow this situation to block grace periods: As long as +all the RCU read-side critical sections are finite, grace periods +must also be finite. + +

+That said, preemptible RCU implementations could potentially result +in RCU read-side critical sections being preempted for long durations, +which has the effect of creating a long-duration RCU read-side +critical section. +This situation can arise only in heavily loaded systems, but systems using +real-time priorities are of course more vulnerable. +Therefore, RCU priority boosting is provided to help deal with this +case. +That said, the exact requirements on RCU priority boosting will likely +evolve as more experience accumulates. + +

+Other workloads might have very high update rates. +Although one can argue that such workloads should instead use +something other than RCU, the fact remains that RCU must +handle such workloads gracefully. +This requirement is another factor driving batching of grace periods, +but it is also the driving force behind the checks for large numbers +of queued RCU callbacks in the call_rcu() code path. +Finally, high update rates should not delay RCU read-side critical +sections, although some read-side delays can occur when using +synchronize_rcu_expedited(), courtesy of this function's use +of try_stop_cpus(). +(In the future, synchronize_rcu_expedited() will be +converted to use lighter-weight inter-processor interrupts (IPIs), +but this will still disturb readers, though to a much smaller degree.) + +

+Although all three of these corner cases were understood in the early +1990s, a simple user-level test consisting of close(open(path)) +in a tight loop +in the early 2000s suddenly provided a much deeper appreciation of the +high-update-rate corner case. +This test also motivated addition of some RCU code to react to high update +rates, for example, if a given CPU finds itself with more than 10,000 +RCU callbacks queued, it will cause RCU to take evasive action by +more aggressively starting grace periods and more aggressively forcing +completion of grace-period processing. +This evasive action causes the grace period to complete more quickly, +but at the cost of restricting RCU's batching optimizations, thus +increasing the CPU overhead incurred by that grace period. + +

+Software-Engineering Requirements

+ +

+Between Murphy's Law and “To err is human”, it is necessary to +guard against mishaps and misuse: + +

    +
  1. It is all too easy to forget to use rcu_read_lock() + everywhere that it is needed, so kernels built with + CONFIG_PROVE_RCU=y will spat if + rcu_dereference() is used outside of an + RCU read-side critical section. + Update-side code can use rcu_dereference_protected(), + which takes a + lockdep expression + to indicate what is providing the protection. + If the indicated protection is not provided, a lockdep splat + is emitted. + +

    + Code shared between readers and updaters can use + rcu_dereference_check(), which also takes a + lockdep expression, and emits a lockdep splat if neither + rcu_read_lock() nor the indicated protection + is in place. + In addition, rcu_dereference_raw() is used in those + (hopefully rare) cases where the required protection cannot + be easily described. + Finally, rcu_read_lock_held() is provided to + allow a function to verify that it has been invoked within + an RCU read-side critical section. + I was made aware of this set of requirements shortly after Thomas + Gleixner audited a number of RCU uses. +

  2. A given function might wish to check for RCU-related preconditions + upon entry, before using any other RCU API. + The rcu_lockdep_assert() does this job, + asserting the expression in kernels having lockdep enabled + and doing nothing otherwise. +
  3. It is also easy to forget to use rcu_assign_pointer() + and rcu_dereference(), perhaps (incorrectly) + substituting a simple assignment. + To catch this sort of error, a given RCU-protected pointer may be + tagged with __rcu, after which running sparse + with CONFIG_SPARSE_RCU_POINTER=y will complain + about simple-assignment accesses to that pointer. + Arnd Bergmann made me aware of this requirement, and also + supplied the needed + patch series. +
  4. Kernels built with CONFIG_DEBUG_OBJECTS_RCU_HEAD=y + will splat if a data element is passed to call_rcu() + twice in a row, without a grace period in between. + (This error is similar to a double free.) + The corresponding rcu_head structures that are + dynamically allocated are automatically tracked, but + rcu_head structures allocated on the stack + must be initialized with init_rcu_head_on_stack() + and cleaned up with destroy_rcu_head_on_stack(). + Similarly, statically allocated non-stack rcu_head + structures must be initialized with init_rcu_head() + and cleaned up with destroy_rcu_head(). + Mathieu Desnoyers made me aware of this requirement, and also + supplied the needed + patch. +
  5. An infinite loop in an RCU read-side critical section will + eventually trigger an RCU CPU stall warning splat, with + the duration of “eventually” being controlled by the + RCU_CPU_STALL_TIMEOUT Kconfig option, or, + alternatively, by the + rcupdate.rcu_cpu_stall_timeout boot/sysfs + parameter. + However, RCU is not obligated to produce this splat + unless there is a grace period waiting on that particular + RCU read-side critical section. +

    + Some extreme workloads might intentionally delay + RCU grace periods, and systems running those workloads can + be booted with rcupdate.rcu_cpu_stall_suppress + to suppress the splats. + This kernel parameter may also be set via sysfs. + Furthermore, RCU CPU stall warnings are counter-productive + during sysrq dumps and during panics. + RCU therefore supplies the rcu_sysrq_start() and + rcu_sysrq_end() API members to be called before + and after long sysrq dumps. + RCU also supplies the rcu_panic() notifier that is + automatically invoked at the beginning of a panic to suppress + further RCU CPU stall warnings. + +

    + This requirement made itself known in the early 1990s, pretty + much the first time that it was necessary to debug a CPU stall. + That said, the initial implementation in DYNIX/ptx was quite + generic in comparison with that of Linux. +

  6. Although it would be very good to detect pointers leaking out + of RCU read-side critical sections, there is currently no + good way of doing this. + One complication is the need to distinguish between pointers + leaking and pointers that have been handed off from RCU to + some other synchronization mechanism, for example, reference + counting. +
  7. In kernels built with CONFIG_RCU_TRACE=y, RCU-related + information is provided via both debugfs and event tracing. +
  8. Open-coded use of rcu_assign_pointer() and + rcu_dereference() to create typical linked + data structures can be surprisingly error-prone. + Therefore, RCU-protected + linked lists + and, more recently, RCU-protected + hash tables + are available. + Many other special-purpose RCU-protected data structures are + available in the Linux kernel and the userspace RCU library. +
  9. Some linked structures are created at compile time, but still + require __rcu checking. + The RCU_POINTER_INITIALIZER() macro serves this + purpose. +
  10. It is not necessary to use rcu_assign_pointer() + when creating linked structures that are to be published via + a single external pointer. + The RCU_INIT_POINTER() macro is provided for + this task and also for assigning NULL pointers + at runtime. +
+ +

+This not a hard-and-fast list: RCU's diagnostic capabilities will +continue to be guided by the number and type of usage bugs found +in real-world RCU usage. + +

Linux Kernel Complications

+ +

+The Linux kernel provides an interesting environment for all kinds of +software, including RCU. +Some of the relevant points of interest are as follows: + +

    +
  1. Configuration. +
  2. Firmware Interface. +
  3. Early Boot. +
  4. + Interrupts and non-maskable interrupts (NMIs). +
  5. Loadable Modules. +
  6. Hotplug CPU. +
  7. Scheduler and RCU. +
  8. Tracing and RCU. +
  9. Energy Efficiency. +
  10. Memory Efficiency. +
  11. + Performance, Scalability, Response Time, and Reliability. +
+ +

+This list is probably incomplete, but it does give a feel for the +most notable Linux-kernel complications. +Each of the following sections covers one of the above topics. + +

Configuration

+ +

+RCU's goal is automatic configuration, so that almost nobody +needs to worry about RCU's Kconfig options. +And for almost all users, RCU does in fact work well +“out of the box.” + +

+However, there are specialized use cases that are handled by +kernel boot parameters and Kconfig options. +Unfortunately, the Kconfig system will explicitly ask users +about new Kconfig options, which requires almost all of them +be hidden behind a CONFIG_RCU_EXPERT Kconfig option. + +

+This all should be quite obvious, but the fact remains that +Linus Torvalds recently had to +remind +me of this requirement. + +

Firmware Interface

+ +

+In many cases, kernel obtains information about the system from the +firmware, and sometimes things are lost in translation. +Or the translation is accurate, but the original message is bogus. + +

+For example, some systems' firmware overreports the number of CPUs, +sometimes by a large factor. +If RCU naively believed the firmware, as it used to do, +it would create too many per-CPU kthreads. +Although the resulting system will still run correctly, the extra +kthreads needlessly consume memory and can cause confusion +when they show up in ps listings. + +

+RCU must therefore wait for a given CPU to actually come online before +it can allow itself to believe that the CPU actually exists. +The resulting “ghost CPUs” (which are never going to +come online) cause a number of +interesting complications. + +

Early Boot

+ +

+The Linux kernel's boot sequence is an interesting process, +and RCU is used early, even before rcu_init() +is invoked. +In fact, a number of RCU's primitives can be used as soon as the +initial task's task_struct is available and the +boot CPU's per-CPU variables are set up. +The read-side primitives (rcu_read_lock(), +rcu_read_unlock(), rcu_dereference(), +and rcu_access_pointer()) will operate normally very early on, +as will rcu_assign_pointer(). + +

+Although call_rcu() may be invoked at any +time during boot, callbacks are not guaranteed to be invoked until after +the scheduler is fully up and running. +This delay in callback invocation is due to the fact that RCU does not +invoke callbacks until it is fully initialized, and this full initialization +cannot occur until after the scheduler has initialized itself to the +point where RCU can spawn and run its kthreads. +In theory, it would be possible to invoke callbacks earlier, +however, this is not a panacea because there would be severe restrictions +on what operations those callbacks could invoke. + +

+Perhaps surprisingly, synchronize_rcu(), +synchronize_rcu_bh() +(discussed below), +and +synchronize_sched() +will all operate normally +during very early boot, the reason being that there is only one CPU +and preemption is disabled. +This means that the call synchronize_rcu() (or friends) +itself is a quiescent +state and thus a grace period, so the early-boot implementation can +be a no-op. + +

+Both synchronize_rcu_bh() and synchronize_sched() +continue to operate normally through the remainder of boot, courtesy +of the fact that preemption is disabled across their RCU read-side +critical sections and also courtesy of the fact that there is still +only one CPU. +However, once the scheduler starts initializing, preemption is enabled. +There is still only a single CPU, but the fact that preemption is enabled +means that the no-op implementation of synchronize_rcu() no +longer works in CONFIG_PREEMPT=y kernels. +Therefore, as soon as the scheduler starts initializing, the early-boot +fastpath is disabled. +This means that synchronize_rcu() switches to its runtime +mode of operation where it posts callbacks, which in turn means that +any call to synchronize_rcu() will block until the corresponding +callback is invoked. +Unfortunately, the callback cannot be invoked until RCU's runtime +grace-period machinery is up and running, which cannot happen until +the scheduler has initialized itself sufficiently to allow RCU's +kthreads to be spawned. +Therefore, invoking synchronize_rcu() during scheduler +initialization can result in deadlock. + +

@@QQ@@ +So what happens with synchronize_rcu() during +scheduler initialization for CONFIG_PREEMPT=n +kernels? +

@@QQA@@ +In CONFIG_PREEMPT=n kernel, synchronize_rcu() +maps directly to synchronize_sched(). +Therefore, synchronize_rcu() works normally throughout +boot in CONFIG_PREEMPT=n kernels. +However, your code must also work in CONFIG_PREEMPT=y kernels, +so it is still necessary to avoid invoking synchronize_rcu() +during scheduler initialization. +

@@QQE@@ + +

+I learned of these boot-time requirements as a result of a series of +system hangs. + +

Interrupts and NMIs

+ +

+The Linux kernel has interrupts, and RCU read-side critical sections are +legal within interrupt handlers and within interrupt-disabled regions +of code, as are invocations of call_rcu(). + +

+Some Linux-kernel architectures can enter an interrupt handler from +non-idle process context, and then just never leave it, instead stealthily +transitioning back to process context. +This trick is sometimes used to invoke system calls from inside the kernel. +These “half-interrupts” mean that RCU has to be very careful +about how it counts interrupt nesting levels. +I learned of this requirement the hard way during a rewrite +of RCU's dyntick-idle code. + +

+The Linux kernel has non-maskable interrupts (NMIs), and +RCU read-side critical sections are legal within NMI handlers. +Thankfully, RCU update-side primitives, including +call_rcu(), are prohibited within NMI handlers. + +

+The name notwithstanding, some Linux-kernel architectures +can have nested NMIs, which RCU must handle correctly. +Andy Lutomirski +surprised me +with this requirement; +he also kindly surprised me with +an algorithm +that meets this requirement. + +

Loadable Modules

+ +

+The Linux kernel has loadable modules, and these modules can +also be unloaded. +After a given module has been unloaded, any attempt to call +one of its functions results in a segmentation fault. +The module-unload functions must therefore cancel any +delayed calls to loadable-module functions, for example, +any outstanding mod_timer() must be dealt with +via del_timer_sync() or similar. + +

+Unfortunately, there is no way to cancel an RCU callback; +once you invoke call_rcu(), the callback function is +going to eventually be invoked, unless the system goes down first. +Because it is normally considered socially irresponsible to crash the system +in response to a module unload request, we need some other way +to deal with in-flight RCU callbacks. + +

+RCU therefore provides +rcu_barrier(), +which waits until all in-flight RCU callbacks have been invoked. +If a module uses call_rcu(), its exit function should therefore +prevent any future invocation of call_rcu(), then invoke +rcu_barrier(). +In theory, the underlying module-unload code could invoke +rcu_barrier() unconditionally, but in practice this would +incur unacceptable latencies. + +

+Nikita Danilov noted this requirement for an analogous filesystem-unmount +situation, and Dipankar Sarma incorporated rcu_barrier() into RCU. +The need for rcu_barrier() for module unloading became +apparent later. + +

Hotplug CPU

+ +

+The Linux kernel supports CPU hotplug, which means that CPUs +can come and go. +It is of course illegal to use any RCU API member from an offline CPU. +This requirement was present from day one in DYNIX/ptx, but +on the other hand, the Linux kernel's CPU-hotplug implementation +is “interesting.” + +

+The Linux-kernel CPU-hotplug implementation has notifiers that +are used to allow the various kernel subsystems (including RCU) +to respond appropriately to a given CPU-hotplug operation. +Most RCU operations may be invoked from CPU-hotplug notifiers, +including even normal synchronous grace-period operations +such as synchronize_rcu(). +However, expedited grace-period operations such as +synchronize_rcu_expedited() are not supported, +due to the fact that current implementations block CPU-hotplug +operations, which could result in deadlock. + +

+In addition, all-callback-wait operations such as +rcu_barrier() are also not supported, due to the +fact that there are phases of CPU-hotplug operations where +the outgoing CPU's callbacks will not be invoked until after +the CPU-hotplug operation ends, which could also result in deadlock. + +

Scheduler and RCU

+ +

+RCU depends on the scheduler, and the scheduler uses RCU to +protect some of its data structures. +This means the scheduler is forbidden from acquiring +the runqueue locks and the priority-inheritance locks +in the middle of an outermost RCU read-side critical section unless either +(1) it releases them before exiting that same +RCU read-side critical section, or +(2) interrupts are disabled across +that entire RCU read-side critical section. +This same prohibition also applies (recursively!) to any lock that is acquired +while holding any lock to which this prohibition applies. +Adhering to this rule prevents preemptible RCU from invoking +rcu_read_unlock_special() while either runqueue or +priority-inheritance locks are held, thus avoiding deadlock. + +

+Prior to v4.4, it was only necessary to disable preemption across +RCU read-side critical sections that acquired scheduler locks. +In v4.4, expedited grace periods started using IPIs, and these +IPIs could force a rcu_read_unlock() to take the slowpath. +Therefore, this expedited-grace-period change required disabling of +interrupts, not just preemption. + +

+For RCU's part, the preemptible-RCU rcu_read_unlock() +implementation must be written carefully to avoid similar deadlocks. +In particular, rcu_read_unlock() must tolerate an +interrupt where the interrupt handler invokes both +rcu_read_lock() and rcu_read_unlock(). +This possibility requires rcu_read_unlock() to use +negative nesting levels to avoid destructive recursion via +interrupt handler's use of RCU. + +

+This pair of mutual scheduler-RCU requirements came as a +complete surprise. + +

+As noted above, RCU makes use of kthreads, and it is necessary to +avoid excessive CPU-time accumulation by these kthreads. +This requirement was no surprise, but RCU's violation of it +when running context-switch-heavy workloads when built with +CONFIG_NO_HZ_FULL=y +did come as a surprise [PDF]. +RCU has made good progress towards meeting this requirement, even +for context-switch-have CONFIG_NO_HZ_FULL=y workloads, +but there is room for further improvement. + +

Tracing and RCU

+ +

+It is possible to use tracing on RCU code, but tracing itself +uses RCU. +For this reason, rcu_dereference_raw_notrace() +is provided for use by tracing, which avoids the destructive +recursion that could otherwise ensue. +This API is also used by virtualization in some architectures, +where RCU readers execute in environments in which tracing +cannot be used. +The tracing folks both located the requirement and provided the +needed fix, so this surprise requirement was relatively painless. + +

Energy Efficiency

+ +

+Interrupting idle CPUs is considered socially unacceptable, +especially by people with battery-powered embedded systems. +RCU therefore conserves energy by detecting which CPUs are +idle, including tracking CPUs that have been interrupted from idle. +This is a large part of the energy-efficiency requirement, +so I learned of this via an irate phone call. + +

+Because RCU avoids interrupting idle CPUs, it is illegal to +execute an RCU read-side critical section on an idle CPU. +(Kernels built with CONFIG_PROVE_RCU=y will splat +if you try it.) +The RCU_NONIDLE() macro and _rcuidle +event tracing is provided to work around this restriction. +In addition, rcu_is_watching() may be used to +test whether or not it is currently legal to run RCU read-side +critical sections on this CPU. +I learned of the need for diagnostics on the one hand +and RCU_NONIDLE() on the other while inspecting +idle-loop code. +Steven Rostedt supplied _rcuidle event tracing, +which is used quite heavily in the idle loop. + +

+It is similarly socially unacceptable to interrupt an +nohz_full CPU running in userspace. +RCU must therefore track nohz_full userspace +execution. +And in +CONFIG_NO_HZ_FULL_SYSIDLE=y +kernels, RCU must separately track idle CPUs on the one hand and +CPUs that are either idle or executing in userspace on the other. +In both cases, RCU must be able to sample state at two points in +time, and be able to determine whether or not some other CPU spent +any time idle and/or executing in userspace. + +

+These energy-efficiency requirements have proven quite difficult to +understand and to meet, for example, there have been more than five +clean-sheet rewrites of RCU's energy-efficiency code, the last of +which was finally able to demonstrate +real energy savings running on real hardware [PDF]. +As noted earlier, +I learned of many of these requirements via angry phone calls: +Flaming me on the Linux-kernel mailing list was apparently not +sufficient to fully vent their ire at RCU's energy-efficiency bugs! + +

Memory Efficiency

+ +

+Although small-memory non-realtime systems can simply use Tiny RCU, +code size is only one aspect of memory efficiency. +Another aspect is the size of the rcu_head structure +used by call_rcu() and kfree_rcu(). +Although this structure contains nothing more than a pair of pointers, +it does appear in many RCU-protected data structures, including +some that are size critical. +The page structure is a case in point, as evidenced by +the many occurrences of the union keyword within that structure. + +

+This need for memory efficiency is one reason that RCU uses hand-crafted +singly linked lists to track the rcu_head structures that +are waiting for a grace period to elapse. +It is also the reason why rcu_head structures do not contain +debug information, such as fields tracking the file and line of the +call_rcu() or kfree_rcu() that posted them. +Although this information might appear in debug-only kernel builds at some +point, in the meantime, the ->func field will often provide +the needed debug information. + +

+However, in some cases, the need for memory efficiency leads to even +more extreme measures. +Returning to the page structure, the rcu_head field +shares storage with a great many other structures that are used at +various points in the corresponding page's lifetime. +In order to correctly resolve certain +race conditions, +the Linux kernel's memory-management subsystem needs a particular bit +to remain zero during all phases of grace-period processing, +and that bit happens to map to the bottom bit of the +rcu_head structure's ->next field. +RCU makes this guarantee as long as call_rcu() +is used to post the callback, as opposed to kfree_rcu() +or some future “lazy” +variant of call_rcu() that might one day be created for +energy-efficiency purposes. + +

+Performance, Scalability, Response Time, and Reliability

+ +

+Expanding on the +earlier discussion, +RCU is used heavily by hot code paths in performance-critical +portions of the Linux kernel's networking, security, virtualization, +and scheduling code paths. +RCU must therefore use efficient implementations, especially in its +read-side primitives. +To that end, it would be good if preemptible RCU's implementation +of rcu_read_lock() could be inlined, however, doing +this requires resolving #include issues with the +task_struct structure. + +

+The Linux kernel supports hardware configurations with up to +4096 CPUs, which means that RCU must be extremely scalable. +Algorithms that involve frequent acquisitions of global locks or +frequent atomic operations on global variables simply cannot be +tolerated within the RCU implementation. +RCU therefore makes heavy use of a combining tree based on the +rcu_node structure. +RCU is required to tolerate all CPUs continuously invoking any +combination of RCU's runtime primitives with minimal per-operation +overhead. +In fact, in many cases, increasing load must decrease the +per-operation overhead, witness the batching optimizations for +synchronize_rcu(), call_rcu(), +synchronize_rcu_expedited(), and rcu_barrier(). +As a general rule, RCU must cheerfully accept whatever the +rest of the Linux kernel decides to throw at it. + +

+The Linux kernel is used for real-time workloads, especially +in conjunction with the +-rt patchset. +The real-time-latency response requirements are such that the +traditional approach of disabling preemption across RCU +read-side critical sections is inappropriate. +Kernels built with CONFIG_PREEMPT=y therefore +use an RCU implementation that allows RCU read-side critical +sections to be preempted. +This requirement made its presence known after users made it +clear that an earlier +real-time patch +did not meet their needs, in conjunction with some +RCU issues +encountered by a very early version of the -rt patchset. + +

+In addition, RCU must make do with a sub-100-microsecond real-time latency +budget. +In fact, on smaller systems with the -rt patchset, the Linux kernel +provides sub-20-microsecond real-time latencies for the whole kernel, +including RCU. +RCU's scalability and latency must therefore be sufficient for +these sorts of configurations. +To my surprise, the sub-100-microsecond real-time latency budget + +applies to even the largest systems [PDF], +up to and including systems with 4096 CPUs. +This real-time requirement motivated the grace-period kthread, which +also simplified handling of a number of race conditions. + +

+Finally, RCU's status as a synchronization primitive means that +any RCU failure can result in arbitrary memory corruption that can be +extremely difficult to debug. +This means that RCU must be extremely reliable, which in +practice also means that RCU must have an aggressive stress-test +suite. +This stress-test suite is called rcutorture. + +

+Although the need for rcutorture was no surprise, +the current immense popularity of the Linux kernel is posing +interesting—and perhaps unprecedented—validation +challenges. +To see this, keep in mind that there are well over one billion +instances of the Linux kernel running today, given Android +smartphones, Linux-powered televisions, and servers. +This number can be expected to increase sharply with the advent of +the celebrated Internet of Things. + +

+Suppose that RCU contains a race condition that manifests on average +once per million years of runtime. +This bug will be occurring about three times per day across +the installed base. +RCU could simply hide behind hardware error rates, given that no one +should really expect their smartphone to last for a million years. +However, anyone taking too much comfort from this thought should +consider the fact that in most jurisdictions, a successful multi-year +test of a given mechanism, which might include a Linux kernel, +suffices for a number of types of safety-critical certifications. +In fact, rumor has it that the Linux kernel is already being used +in production for safety-critical applications. +I don't know about you, but I would feel quite bad if a bug in RCU +killed someone. +Which might explain my recent focus on validation and verification. + +

Other RCU Flavors

+ +

+One of the more surprising things about RCU is that there are now +no fewer than five flavors, or API families. +In addition, the primary flavor that has been the sole focus up to +this point has two different implementations, non-preemptible and +preemptible. +The other four flavors are listed below, with requirements for each +described in a separate section. + +

+The softirq-disable (AKA “bottom-half”, +hence the “_bh” abbreviations) +flavor of RCU, or RCU-bh, was developed by +Dipankar Sarma to provide a flavor of RCU that could withstand the +network-based denial-of-service attacks researched by Robert +Olsson. +These attacks placed so much networking load on the system +that some of the CPUs never exited softirq execution, +which in turn prevented those CPUs from ever executing a context switch, +which, in the RCU implementation of that time, prevented grace periods +from ever ending. +The result was an out-of-memory condition and a system hang. + +

+The solution was the creation of RCU-bh, which does +local_bh_disable() +across its read-side critical sections, and which uses the transition +from one type of softirq processing to another as a quiescent state +in addition to context switch, idle, user mode, and offline. +This means that RCU-bh grace periods can complete even when some of +the CPUs execute in softirq indefinitely, thus allowing algorithms +based on RCU-bh to withstand network-based denial-of-service attacks. + +

+Because +rcu_read_lock_bh() and rcu_read_unlock_bh() +disable and re-enable softirq handlers, any attempt to start a softirq +handlers during the +RCU-bh read-side critical section will be deferred. +In this case, rcu_read_unlock_bh() +will invoke softirq processing, which can take considerable time. +One can of course argue that this softirq overhead should be associated +with the code following the RCU-bh read-side critical section rather +than rcu_read_unlock_bh(), but the fact +is that most profiling tools cannot be expected to make this sort +of fine distinction. +For example, suppose that a three-millisecond-long RCU-bh read-side +critical section executes during a time of heavy networking load. +There will very likely be an attempt to invoke at least one softirq +handler during that three milliseconds, but any such invocation will +be delayed until the time of the rcu_read_unlock_bh(). +This can of course make it appear at first glance as if +rcu_read_unlock_bh() was executing very slowly. + +

+The +RCU-bh API +includes +rcu_read_lock_bh(), +rcu_read_unlock_bh(), +rcu_dereference_bh(), +rcu_dereference_bh_check(), +synchronize_rcu_bh(), +synchronize_rcu_bh_expedited(), +call_rcu_bh(), +rcu_barrier_bh(), and +rcu_read_lock_bh_held(). + +

Sched Flavor

+ +

+Before preemptible RCU, waiting for an RCU grace period had the +side effect of also waiting for all pre-existing interrupt +and NMI handlers. +However, there are legitimate preemptible-RCU implementations that +do not have this property, given that any point in the code outside +of an RCU read-side critical section can be a quiescent state. +Therefore, RCU-sched was created, which follows “classic” +RCU in that an RCU-sched grace period waits for for pre-existing +interrupt and NMI handlers. +In kernels built with CONFIG_PREEMPT=n, the RCU and RCU-sched +APIs have identical implementations, while kernels built with +CONFIG_PREEMPT=y provide a separate implementation for each. + +

+Note well that in CONFIG_PREEMPT=y kernels, +rcu_read_lock_sched() and rcu_read_unlock_sched() +disable and re-enable preemption, respectively. +This means that if there was a preemption attempt during the +RCU-sched read-side critical section, rcu_read_unlock_sched() +will enter the scheduler, with all the latency and overhead entailed. +Just as with rcu_read_unlock_bh(), this can make it look +as if rcu_read_unlock_sched() was executing very slowly. +However, the highest-priority task won't be preempted, so that task +will enjoy low-overhead rcu_read_unlock_sched() invocations. + +

+The +RCU-sched API +includes +rcu_read_lock_sched(), +rcu_read_unlock_sched(), +rcu_read_lock_sched_notrace(), +rcu_read_unlock_sched_notrace(), +rcu_dereference_sched(), +rcu_dereference_sched_check(), +synchronize_sched(), +synchronize_rcu_sched_expedited(), +call_rcu_sched(), +rcu_barrier_sched(), and +rcu_read_lock_sched_held(). +However, anything that disables preemption also marks an RCU-sched +read-side critical section, including +preempt_disable() and preempt_enable(), +local_irq_save() and local_irq_restore(), +and so on. + +

Sleepable RCU

+ +

+For well over a decade, someone saying “I need to block within +an RCU read-side critical section” was a reliable indication +that this someone did not understand RCU. +After all, if you are always blocking in an RCU read-side critical +section, you can probably afford to use a higher-overhead synchronization +mechanism. +However, that changed with the advent of the Linux kernel's notifiers, +whose RCU read-side critical +sections almost never sleep, but sometimes need to. +This resulted in the introduction of +sleepable RCU, +or SRCU. + +

+SRCU allows different domains to be defined, with each such domain +defined by an instance of an srcu_struct structure. +A pointer to this structure must be passed in to each SRCU function, +for example, synchronize_srcu(&ss), where +ss is the srcu_struct structure. +The key benefit of these domains is that a slow SRCU reader in one +domain does not delay an SRCU grace period in some other domain. +That said, one consequence of these domains is that read-side code +must pass a “cookie” from srcu_read_lock() +to srcu_read_unlock(), for example, as follows: + +

+
+ 1 int idx;
+ 2
+ 3 idx = srcu_read_lock(&ss);
+ 4 do_something();
+ 5 srcu_read_unlock(&ss, idx);
+
+
+ +

+As noted above, it is legal to block within SRCU read-side critical sections, +however, with great power comes great responsibility. +If you block forever in one of a given domain's SRCU read-side critical +sections, then that domain's grace periods will also be blocked forever. +Of course, one good way to block forever is to deadlock, which can +happen if any operation in a given domain's SRCU read-side critical +section can block waiting, either directly or indirectly, for that domain's +grace period to elapse. +For example, this results in a self-deadlock: + +

+
+ 1 int idx;
+ 2
+ 3 idx = srcu_read_lock(&ss);
+ 4 do_something();
+ 5 synchronize_srcu(&ss);
+ 6 srcu_read_unlock(&ss, idx);
+
+
+ +

+However, if line 5 acquired a mutex that was held across +a synchronize_srcu() for domain ss, +deadlock would still be possible. +Furthermore, if line 5 acquired a mutex that was held across +a synchronize_srcu() for some other domain ss1, +and if an ss1-domain SRCU read-side critical section +acquired another mutex that was held across as ss-domain +synchronize_srcu(), +deadlock would again be possible. +Such a deadlock cycle could extend across an arbitrarily large number +of different SRCU domains. +Again, with great power comes great responsibility. + +

+Unlike the other RCU flavors, SRCU read-side critical sections can +run on idle and even offline CPUs. +This ability requires that srcu_read_lock() and +srcu_read_unlock() contain memory barriers, which means +that SRCU readers will run a bit slower than would RCU readers. +It also motivates the smp_mb__after_srcu_read_unlock() +API, which, in combination with srcu_read_unlock(), +guarantees a full memory barrier. + +

+The +SRCU API +includes +srcu_read_lock(), +srcu_read_unlock(), +srcu_dereference(), +srcu_dereference_check(), +synchronize_srcu(), +synchronize_srcu_expedited(), +call_srcu(), +srcu_barrier(), and +srcu_read_lock_held(). +It also includes +DEFINE_SRCU(), +DEFINE_STATIC_SRCU(), and +init_srcu_struct() +APIs for defining and initializing srcu_struct structures. + +

Tasks RCU

+ +

+Some forms of tracing use “tramopolines” to handle the +binary rewriting required to install different types of probes. +It would be good to be able to free old trampolines, which sounds +like a job for some form of RCU. +However, because it is necessary to be able to install a trace +anywhere in the code, it is not possible to use read-side markers +such as rcu_read_lock() and rcu_read_unlock(). +In addition, it does not work to have these markers in the trampoline +itself, because there would need to be instructions following +rcu_read_unlock(). +Although synchronize_rcu() would guarantee that execution +reached the rcu_read_unlock(), it would not be able to +guarantee that execution had completely left the trampoline. + +

+The solution, in the form of +Tasks RCU, +is to have implicit +read-side critical sections that are delimited by voluntary context +switches, that is, calls to schedule(), +cond_resched_rcu_qs(), and +synchronize_rcu_tasks(). +In addition, transitions to and from userspace execution also delimit +tasks-RCU read-side critical sections. + +

+The tasks-RCU API is quite compact, consisting only of +call_rcu_tasks(), +synchronize_rcu_tasks(), and +rcu_barrier_tasks(). + +

Possible Future Changes

+ +

+One of the tricks that RCU uses to attain update-side scalability is +to increase grace-period latency with increasing numbers of CPUs. +If this becomes a serious problem, it will be necessary to rework the +grace-period state machine so as to avoid the need for the additional +latency. + +

+Expedited grace periods scan the CPUs, so their latency and overhead +increases with increasing numbers of CPUs. +If this becomes a serious problem on large systems, it will be necessary +to do some redesign to avoid this scalability problem. + +

+RCU disables CPU hotplug in a few places, perhaps most notably in the +expedited grace-period and rcu_barrier() operations. +If there is a strong reason to use expedited grace periods in CPU-hotplug +notifiers, it will be necessary to avoid disabling CPU hotplug. +This would introduce some complexity, so there had better be a very +good reason. + +

+The tradeoff between grace-period latency on the one hand and interruptions +of other CPUs on the other hand may need to be re-examined. +The desire is of course for zero grace-period latency as well as zero +interprocessor interrupts undertaken during an expedited grace period +operation. +While this ideal is unlikely to be achievable, it is quite possible that +further improvements can be made. + +

+The multiprocessor implementations of RCU use a combining tree that +groups CPUs so as to reduce lock contention and increase cache locality. +However, this combining tree does not spread its memory across NUMA +nodes nor does it align the CPU groups with hardware features such +as sockets or cores. +Such spreading and alignment is currently believed to be unnecessary +because the hotpath read-side primitives do not access the combining +tree, nor does call_rcu() in the common case. +If you believe that your architecture needs such spreading and alignment, +then your architecture should also benefit from the +rcutree.rcu_fanout_leaf boot parameter, which can be set +to the number of CPUs in a socket, NUMA node, or whatever. +If the number of CPUs is too large, use a fraction of the number of +CPUs. +If the number of CPUs is a large prime number, well, that certainly +is an “interesting” architectural choice! +More flexible arrangements might be considered, but only if +rcutree.rcu_fanout_leaf has proven inadequate, and only +if the inadequacy has been demonstrated by a carefully run and +realistic system-level workload. + +

+Please note that arrangements that require RCU to remap CPU numbers will +require extremely good demonstration of need and full exploration of +alternatives. + +

+There is an embarrassingly large number of flavors of RCU, and this +number has been increasing over time. +Perhaps it will be possible to combine some at some future date. + +

+RCU's various kthreads are reasonably recent additions. +It is quite likely that adjustments will be required to more gracefully +handle extreme loads. +It might also be necessary to be able to relate CPU utilization by +RCU's kthreads and softirq handlers to the code that instigated this +CPU utilization. +For example, RCU callback overhead might be charged back to the +originating call_rcu() instance, though probably not +in production kernels. + +

Summary

+ +

+This document has presented more than two decade's worth of RCU +requirements. +Given that the requirements keep changing, this will not be the last +word on this subject, but at least it serves to get an important +subset of the requirements set forth. + +

Terminology + +"cgroup" stands for "control group" and is never capitalized. The +singular form is used to designate the whole feature and also as a +qualifier as in "cgroup controllers". When explicitly referring to +multiple individual control groups, the plural form "cgroups" is used. + + +1-2. What is cgroup? + +cgroup is a mechanism to organize processes hierarchically and +distribute system resources along the hierarchy in a controlled and +configurable manner. + +cgroup is largely composed of two parts - the core and controllers. +cgroup core is primarily responsible for hierarchically organizing +processes. A cgroup controller is usually responsible for +distributing a specific type of system resource along the hierarchy +although there are utility controllers which serve purposes other than +resource distribution. + +cgroups form a tree structure and every process in the system belongs +to one and only one cgroup. All threads of a process belong to the +same cgroup. On creation, all processes are put in the cgroup that +the parent process belongs to at the time. A process can be migrated +to another cgroup. Migration of a process doesn't affect already +existing descendant processes. + +Following certain structural constraints, controllers may be enabled or +disabled selectively on a cgroup. All controller behaviors are +hierarchical - if a controller is enabled on a cgroup, it affects all +processes which belong to the cgroups consisting the inclusive +sub-hierarchy of the cgroup. When a controller is enabled on a nested +cgroup, it always restricts the resource distribution further. The +restrictions set closer to the root in the hierarchy can not be +overridden from further away. + + +2. Basic Operations + +2-1. Mounting + +Unlike v1, cgroup v2 has only single hierarchy. The cgroup v2 +hierarchy can be mounted with the following mount command. + + # mount -t cgroup2 none $MOUNT_POINT + +cgroup2 filesystem has the magic number 0x63677270 ("cgrp"). All +controllers which support v2 and are not bound to a v1 hierarchy are +automatically bound to the v2 hierarchy and show up at the root. +Controllers which are not in active use in the v2 hierarchy can be +bound to other hierarchies. This allows mixing v2 hierarchy with the +legacy v1 multiple hierarchies in a fully backward compatible way. + +A controller can be moved across hierarchies only after the controller +is no longer referenced in its current hierarchy. Because per-cgroup +controller states are destroyed asynchronously and controllers may +have lingering references, a controller may not show up immediately on +the v2 hierarchy after the final umount of the previous hierarchy. +Similarly, a controller should be fully disabled to be moved out of +the unified hierarchy and it may take some time for the disabled +controller to become available for other hierarchies; furthermore, due +to inter-controller dependencies, other controllers may need to be +disabled too. + +While useful for development and manual configurations, moving +controllers dynamically between the v2 and other hierarchies is +strongly discouraged for production use. It is recommended to decide +the hierarchies and controller associations before starting using the +controllers after system boot. + + +2-2. Organizing Processes + +Initially, only the root cgroup exists to which all processes belong. +A child cgroup can be created by creating a sub-directory. + + # mkdir $CGROUP_NAME + +A given cgroup may have multiple child cgroups forming a tree +structure. Each cgroup has a read-writable interface file +"cgroup.procs". When read, it lists the PIDs of all processes which +belong to the cgroup one-per-line. The PIDs are not ordered and the +same PID may show up more than once if the process got moved to +another cgroup and then back or the PID got recycled while reading. + +A process can be migrated into a cgroup by writing its PID to the +target cgroup's "cgroup.procs" file. Only one process can be migrated +on a single write(2) call. If a process is composed of multiple +threads, writing the PID of any thread migrates all threads of the +process. + +When a process forks a child process, the new process is born into the +cgroup that the forking process belongs to at the time of the +operation. After exit, a process stays associated with the cgroup +that it belonged to at the time of exit until it's reaped; however, a +zombie process does not appear in "cgroup.procs" and thus can't be +moved to another cgroup. + +A cgroup which doesn't have any children or live processes can be +destroyed by removing the directory. Note that a cgroup which doesn't +have any children and is associated only with zombie processes is +considered empty and can be removed. + + # rmdir $CGROUP_NAME + +"/proc/$PID/cgroup" lists a process's cgroup membership. If legacy +cgroup is in use in the system, this file may contain multiple lines, +one for each hierarchy. The entry for cgroup v2 is always in the +format "0::$PATH". + + # cat /proc/842/cgroup + ... + 0::/test-cgroup/test-cgroup-nested + +If the process becomes a zombie and the cgroup it was associated with +is removed subsequently, " (deleted)" is appended to the path. + + # cat /proc/842/cgroup + ... + 0::/test-cgroup/test-cgroup-nested (deleted) + + +2-3. [Un]populated Notification + +Each non-root cgroup has a "cgroup.events" file which contains +"populated" field indicating whether the cgroup's sub-hierarchy has +live processes in it. Its value is 0 if there is no live process in +the cgroup and its descendants; otherwise, 1. poll and [id]notify +events are triggered when the value changes. This can be used, for +example, to start a clean-up operation after all processes of a given +sub-hierarchy have exited. The populated state updates and +notifications are recursive. Consider the following sub-hierarchy +where the numbers in the parentheses represent the numbers of processes +in each cgroup. + + A(4) - B(0) - C(1) + \ D(0) + +A, B and C's "populated" fields would be 1 while D's 0. After the one +process in C exits, B and C's "populated" fields would flip to "0" and +file modified events will be generated on the "cgroup.events" files of +both cgroups. + + +2-4. Controlling Controllers + +2-4-1. Enabling and Disabling + +Each cgroup has a "cgroup.controllers" file which lists all +controllers available for the cgroup to enable. + + # cat cgroup.controllers + cpu io memory + +No controller is enabled by default. Controllers can be enabled and +disabled by writing to the "cgroup.subtree_control" file. + + # echo "+cpu +memory -io" > cgroup.subtree_control + +Only controllers which are listed in "cgroup.controllers" can be +enabled. When multiple operations are specified as above, either they +all succeed or fail. If multiple operations on the same controller +are specified, the last one is effective. + +Enabling a controller in a cgroup indicates that the distribution of +the target resource across its immediate children will be controlled. +Consider the following sub-hierarchy. The enabled controllers are +listed in parentheses. + + A(cpu,memory) - B(memory) - C() + \ D() + +As A has "cpu" and "memory" enabled, A will control the distribution +of CPU cycles and memory to its children, in this case, B. As B has +"memory" enabled but not "CPU", C and D will compete freely on CPU +cycles but their division of memory available to B will be controlled. + +As a controller regulates the distribution of the target resource to +the cgroup's children, enabling it creates the controller's interface +files in the child cgroups. In the above example, enabling "cpu" on B +would create the "cpu." prefixed controller interface files in C and +D. Likewise, disabling "memory" from B would remove the "memory." +prefixed controller interface files from C and D. This means that the +controller interface files - anything which doesn't start with +"cgroup." are owned by the parent rather than the cgroup itself. + + +2-4-2. Top-down Constraint + +Resources are distributed top-down and a cgroup can further distribute +a resource only if the resource has been distributed to it from the +parent. This means that all non-root "cgroup.subtree_control" files +can only contain controllers which are enabled in the parent's +"cgroup.subtree_control" file. A controller can be enabled only if +the parent has the controller enabled and a controller can't be +disabled if one or more children have it enabled. + + +2-4-3. No Internal Process Constraint + +Non-root cgroups can only distribute resources to their children when +they don't have any processes of their own. In other words, only +cgroups which don't contain any processes can have controllers enabled +in their "cgroup.subtree_control" files. + +This guarantees that, when a controller is looking at the part of the +hierarchy which has it enabled, processes are always only on the +leaves. This rules out situations where child cgroups compete against +internal processes of the parent. + +The root cgroup is exempt from this restriction. Root contains +processes and anonymous resource consumption which can't be associated +with any other cgroups and requires special treatment from most +controllers. How resource consumption in the root cgroup is governed +is up to each controller. + +Note that the restriction doesn't get in the way if there is no +enabled controller in the cgroup's "cgroup.subtree_control". This is +important as otherwise it wouldn't be possible to create children of a +populated cgroup. To control resource distribution of a cgroup, the +cgroup must create children and transfer all its processes to the +children before enabling controllers in its "cgroup.subtree_control" +file. + + +2-5. Delegation + +2-5-1. Model of Delegation + +A cgroup can be delegated to a less privileged user by granting write +access of the directory and its "cgroup.procs" file to the user. Note +that resource control interface files in a given directory control the +distribution of the parent's resources and thus must not be delegated +along with the directory. + +Once delegated, the user can build sub-hierarchy under the directory, +organize processes as it sees fit and further distribute the resources +it received from the parent. The limits and other settings of all +resource controllers are hierarchical and regardless of what happens +in the delegated sub-hierarchy, nothing can escape the resource +restrictions imposed by the parent. + +Currently, cgroup doesn't impose any restrictions on the number of +cgroups in or nesting depth of a delegated sub-hierarchy; however, +this may be limited explicitly in the future. + + +2-5-2. Delegation Containment + +A delegated sub-hierarchy is contained in the sense that processes +can't be moved into or out of the sub-hierarchy by the delegatee. For +a process with a non-root euid to migrate a target process into a +cgroup by writing its PID to the "cgroup.procs" file, the following +conditions must be met. + +- The writer's euid must match either uid or suid of the target process. + +- The writer must have write access to the "cgroup.procs" file. + +- The writer must have write access to the "cgroup.procs" file of the + common ancestor of the source and destination cgroups. + +The above three constraints ensure that while a delegatee may migrate +processes around freely in the delegated sub-hierarchy it can't pull +in from or push out to outside the sub-hierarchy. + +For an example, let's assume cgroups C0 and C1 have been delegated to +user U0 who created C00, C01 under C0 and C10 under C1 as follows and +all processes under C0 and C1 belong to U0. + + ~~~~~~~~~~~~~ - C0 - C00 + ~ cgroup ~ \ C01 + ~ hierarchy ~ + ~~~~~~~~~~~~~ - C1 - C10 + +Let's also say U0 wants to write the PID of a process which is +currently in C10 into "C00/cgroup.procs". U0 has write access to the +file and uid match on the process; however, the common ancestor of the +source cgroup C10 and the destination cgroup C00 is above the points +of delegation and U0 would not have write access to its "cgroup.procs" +files and thus the write will be denied with -EACCES. + + +2-6. Guidelines + +2-6-1. Organize Once and Control + +Migrating a process across cgroups is a relatively expensive operation +and stateful resources such as memory are not moved together with the +process. This is an explicit design decision as there often exist +inherent trade-offs between migration and various hot paths in terms +of synchronization cost. + +As such, migrating processes across cgroups frequently as a means to +apply different resource restrictions is discouraged. A workload +should be assigned to a cgroup according to the system's logical and +resource structure once on start-up. Dynamic adjustments to resource +distribution can be made by changing controller configuration through +the interface files. + + +2-6-2. Avoid Name Collisions + +Interface files for a cgroup and its children cgroups occupy the same +directory and it is possible to create children cgroups which collide +with interface files. + +All cgroup core interface files are prefixed with "cgroup." and each +controller's interface files are prefixed with the controller name and +a dot. A controller's name is composed of lower case alphabets and +'_'s but never begins with an '_' so it can be used as the prefix +character for collision avoidance. Also, interface file names won't +start or end with terms which are often used in categorizing workloads +such as job, service, slice, unit or workload. + +cgroup doesn't do anything to prevent name collisions and it's the +user's responsibility to avoid them. + + +3. Resource Distribution Models + +cgroup controllers implement several resource distribution schemes +depending on the resource type and expected use cases. This section +describes major schemes in use along with their expected behaviors. + + +3-1. Weights + +A parent's resource is distributed by adding up the weights of all +active children and giving each the fraction matching the ratio of its +weight against the sum. As only children which can make use of the +resource at the moment participate in the distribution, this is +work-conserving. Due to the dynamic nature, this model is usually +used for stateless resources. + +All weights are in the range [1, 10000] with the default at 100. This +allows symmetric multiplicative biases in both directions at fine +enough granularity while staying in the intuitive range. + +As long as the weight is in range, all configuration combinations are +valid and there is no reason to reject configuration changes or +process migrations. + +"cpu.weight" proportionally distributes CPU cycles to active children +and is an example of this type. + + +3-2. Limits + +A child can only consume upto the configured amount of the resource. +Limits can be over-committed - the sum of the limits of children can +exceed the amount of resource available to the parent. + +Limits are in the range [0, max] and defaults to "max", which is noop. + +As limits can be over-committed, all configuration combinations are +valid and there is no reason to reject configuration changes or +process migrations. + +"io.max" limits the maximum BPS and/or IOPS that a cgroup can consume +on an IO device and is an example of this type. + + +3-3. Protections + +A cgroup is protected to be allocated upto the configured amount of +the resource if the usages of all its ancestors are under their +protected levels. Protections can be hard guarantees or best effort +soft boundaries. Protections can also be over-committed in which case +only upto the amount available to the parent is protected among +children. + +Protections are in the range [0, max] and defaults to 0, which is +noop. + +As protections can be over-committed, all configuration combinations +are valid and there is no reason to reject configuration changes or +process migrations. + +"memory.low" implements best-effort memory protection and is an +example of this type. + + +3-4. Allocations + +A cgroup is exclusively allocated a certain amount of a finite +resource. Allocations can't be over-committed - the sum of the +allocations of children can not exceed the amount of resource +available to the parent. + +Allocations are in the range [0, max] and defaults to 0, which is no +resource. + +As allocations can't be over-committed, some configuration +combinations are invalid and should be rejected. Also, if the +resource is mandatory for execution of processes, process migrations +may be rejected. + +"cpu.rt.max" hard-allocates realtime slices and is an example of this +type. + + +4. Interface Files + +4-1. Format + +All interface files should be in one of the following formats whenever +possible. + + New-line separated values + (when only one value can be written at once) + + VAL0\n + VAL1\n + ... + + Space separated values + (when read-only or multiple values can be written at once) + + VAL0 VAL1 ...\n + + Flat keyed + + KEY0 VAL0\n + KEY1 VAL1\n + ... + + Nested keyed + + KEY0 SUB_KEY0=VAL00 SUB_KEY1=VAL01... + KEY1 SUB_KEY0=VAL10 SUB_KEY1=VAL11... + ... + +For a writable file, the format for writing should generally match +reading; however, controllers may allow omitting later fields or +implement restricted shortcuts for most common use cases. + +For both flat and nested keyed files, only the values for a single key +can be written at a time. For nested keyed files, the sub key pairs +may be specified in any order and not all pairs have to be specified. + + +4-2. Conventions + +- Settings for a single feature should be contained in a single file. + +- The root cgroup should be exempt from resource control and thus + shouldn't have resource control interface files. Also, + informational files on the root cgroup which end up showing global + information available elsewhere shouldn't exist. + +- If a controller implements weight based resource distribution, its + interface file should be named "weight" and have the range [1, + 10000] with 100 as the default. The values are chosen to allow + enough and symmetric bias in both directions while keeping it + intuitive (the default is 100%). + +- If a controller implements an absolute resource guarantee and/or + limit, the interface files should be named "min" and "max" + respectively. If a controller implements best effort resource + guarantee and/or limit, the interface files should be named "low" + and "high" respectively. + + In the above four control files, the special token "max" should be + used to represent upward infinity for both reading and writing. + +- If a setting has a configurable default value and keyed specific + overrides, the default entry should be keyed with "default" and + appear as the first entry in the file. + + The default value can be updated by writing either "default $VAL" or + "$VAL". + + When writing to update a specific override, "default" can be used as + the value to indicate removal of the override. Override entries + with "default" as the value must not appear when read. + + For example, a setting which is keyed by major:minor device numbers + with integer values may look like the following. + + # cat cgroup-example-interface-file + default 150 + 8:0 300 + + The default value can be updated by + + # echo 125 > cgroup-example-interface-file + + or + + # echo "default 125" > cgroup-example-interface-file + + An override can be set by + + # echo "8:16 170" > cgroup-example-interface-file + + and cleared by + + # echo "8:0 default" > cgroup-example-interface-file + # cat cgroup-example-interface-file + default 125 + 8:16 170 + +- For events which are not very high frequency, an interface file + "events" should be created which lists event key value pairs. + Whenever a notifiable event happens, file modified event should be + generated on the file. + + +4-3.

As long as the + high limit is used and monitored properly, this limit's + utility is limited to providing the final safety net. + + memory.events + + A read-only flat-keyed file which exists on non-root cgroups. + The following entries are defined. Unless specified + otherwise, a value change in this file generates a file + modified event. + + low + + The number of times the cgroup is reclaimed due to + high memory pressure even though its usage is under + the low boundary. This usually indicates that the low + boundary is over-committed. + + high + + The number of times processes of the cgroup are + throttled and routed to perform direct memory reclaim + because the high memory boundary was exceeded.

General Usage + +"memory.high" is the main mechanism to control memory usage. +Over-committing on high limit (sum of high limits > available memory) +and letting global memory pressure to distribute memory according to +usage is a viable strategy. + +Because breach of the high limit doesn't trigger the OOM killer but +throttles the offending cgroup, a management agent has ample +opportunities to monitor and take appropriate actions such as granting +more memory or terminating the workload. + +Determining whether a cgroup has enough memory is not trivial as +memory usage doesn't indicate whether the workload can benefit from +more memory. For example, a workload which writes data received from +network to a file can use all available memory but can also operate as +performant with a small amount of memory. A measure of memory +pressure - how much the workload is being impacted due to lack of +memory - is necessary to determine whether a workload needs more +memory; unfortunately, memory pressure monitoring mechanism isn't +implemented yet. + + +5-2-3. Memory Ownership + +A memory area is charged to the cgroup which instantiated it and stays +charged to the cgroup until the area is released. Migrating a process +to a different cgroup doesn't move the memory usages that it +instantiated while in the previous cgroup to the new cgroup. + +A memory area may be used by processes belonging to different cgroups. +To which cgroup the area will be charged is in-deterministic; however, +over time, the memory area is likely to end up in a cgroup which has +enough memory allowance to avoid high reclaim pressure. + +If a cgroup sweeps a considerable amount of memory which is expected +to be accessed repeatedly by other cgroups, it may make sense to use +POSIX_FADV_DONTNEED to relinquish the ownership of memory areas +belonging to the affected files to ensure correct memory ownership. + + +5-3. IO + +The "io" controller regulates the distribution of IO resources.

Writeback + +Page cache is dirtied through buffered writes and shared mmaps and +written asynchronously to the backing filesystem by the writeback +mechanism. Writeback sits between the memory and IO domains and +regulates the proportion of dirty memory by balancing dirtying and +write IOs. + +The io controller, in conjunction with the memory controller, +implements control of page cache writeback IOs. The memory controller +defines the memory domain that dirty memory ratio is calculated and +maintained for and the io controller defines the io domain which +writes out dirty pages for the memory domain. Both system-wide and +per-cgroup dirty memory states are examined and the more restrictive +of the two is enforced. + +cgroup writeback requires explicit support from the underlying +filesystem. Currently, cgroup writeback is implemented on ext2, ext4 +and btrfs. On other filesystems, all writeback IOs are attributed to +the root cgroup. + +There are inherent differences in memory and writeback management +which affects how cgroup ownership is tracked. Memory is tracked per +page while writeback per inode. For the purpose of writeback, an +inode is assigned to a cgroup and all IO requests to write dirty pages +from the inode are attributed to that cgroup. + +As cgroup ownership for memory is tracked per page, there can be pages +which are associated with different cgroups than the one the inode is +associated with. These are called foreign pages. The writeback +constantly keeps track of foreign pages and, if a particular foreign +cgroup becomes the majority over a certain period of time, switches +the ownership of the inode to that cgroup. + +While this model is enough for most use cases where a given inode is +mostly dirtied by a single cgroup even when the main writing cgroup +changes over time, use cases where multiple cgroups write to a single +inode simultaneously are not supported well. In such circumstances, a +significant portion of IOs are likely to be attributed incorrectly. +As memory controller assigns page ownership on the first use and +doesn't update it until the page is released, even if writeback +strictly follows page ownership, multiple cgroups dirtying overlapping +areas wouldn't work as expected. It's recommended to avoid such usage +patterns. + +The sysctl knobs which affect writeback behavior are applied to cgroup +writeback as follows. + + vm.dirty_background_ratio + vm.dirty_ratio + + These ratios apply the same to cgroup writeback with the + amount of available memory capped by limits imposed by the + memory controller and system-wide clean memory. + + vm.dirty_background_bytes + vm.dirty_bytes + + For cgroup writeback, this is calculated into ratio against + total available memory and applied the same way as + vm.dirty[_background]_ratio. + + +P. Information on Kernel Programming + +This section contains kernel programming information in the areas +where interacting with cgroup is necessary. cgroup core and +controllers are not covered. + + +P-1. Filesystem Support for Writeback + +A filesystem can support cgroup writeback by updating +address_space_operations->writepage[s]() to annotate bio's using the +following two functions. + + wbc_init_bio(@wbc, @bio) + + Should be called for each bio carrying writeback data and + associates the bio with the inode's owner cgroup. Can be + called anytime between bio allocation and submission. + + wbc_account_io(@wbc, @page, @bytes) + + Should be called for each data segment being written out. + While this function doesn't care exactly when it's called + during the writeback session, it's the easiest and most + natural to call it as data segments are added to a bio. + +With writeback bio's annotated, cgroup support can be enabled per +super_block by setting SB_I_CGROUPWB in ->s_iflags. This allows for +selective disabling of cgroup writeback support which is helpful when +certain filesystem features, e.g. journaled data mode, are +incompatible. + +wbc_init_bio() binds the specified bio to its cgroup. Depending on +the configuration, the bio may be executed at a lower priority and if +the writeback session is holding shared resources, e.g. a journal +entry, may lead to priority inversion. There is no one easy solution +for the problem. Filesystems can try to work around specific problem +cases by skipping wbc_init_bio() or using bio_associate_blkcg() +directly. + + +D. Deprecated v1 Core Features + +- Multiple hierarchies including named ones are not supported. + +- All mount options and remounting are not supported. + +- The "tasks" file is removed and "cgroup.procs" is not sorted. + +- "cgroup.clone_children" is removed. + +- /proc/cgroups is meaningless for v2. Use "cgroup.controllers" file + at the root instead. + + +R. Issues with v1 and Rationales for v2 + +R-1. Multiple Hierarchies + +cgroup v1 allowed an arbitrary number of hierarchies and each +hierarchy could host any number of controllers. While this seemed to +provide a high level of flexibility, it wasn't useful in practice. + +For example, as there is only one instance of each controller, utility +type controllers such as freezer which can be useful in all +hierarchies could only be used in one. The issue is exacerbated by +the fact that controllers couldn't be moved to another hierarchy once +hierarchies were populated. Another issue was that all controllers +bound to a hierarchy were forced to have exactly the same view of the +hierarchy. It wasn't possible to vary the granularity depending on +the specific controller. + +In practice, these issues heavily limited which controllers could be +put on the same hierarchy and most configurations resorted to putting +each controller on its own hierarchy. Only closely related ones, such +as the cpu and cpuacct controllers, made sense to be put on the same +hierarchy. This often meant that userland ended up managing multiple +similar hierarchies repeating the same steps on each hierarchy +whenever a hierarchy management operation was necessary. + +Furthermore, support for multiple hierarchies came at a steep cost. +It greatly complicated cgroup core implementation but more importantly +the support for multiple hierarchies restricted how cgroup could be +used in general and what controllers was able to do. + +There was no limit on how many hierarchies there might be, which meant +that a thread's cgroup membership couldn't be described in finite +length. The key might contain any number of entries and was unlimited +in length, which made it highly awkward to manipulate and led to +addition of controllers which existed only to identify membership, +which in turn exacerbated the original problem of proliferating number +of hierarchies. + +Also, as a controller couldn't have any expectation regarding the +topologies of hierarchies other controllers might be on, each +controller had to assume that all other controllers were attached to +completely orthogonal hierarchies. This made it impossible, or at +least very cumbersome, for controllers to cooperate with each other. + +In most use cases, putting controllers on hierarchies which are +completely orthogonal to each other isn't necessary. What usually is +called for is the ability to have differing levels of granularity +depending on the specific controller. In other words, hierarchy may +be collapsed from leaf towards root when viewed from specific +controllers. For example, a given configuration might not care about +how memory is distributed beyond a certain level while still wanting +to control how CPU cycles are distributed. + + +R-2. Thread Granularity + +cgroup v1 allowed threads of a process to belong to different cgroups. +This didn't make sense for some controllers and those controllers +ended up implementing different ways to ignore such situations but +much more importantly it blurred the line between API exposed to +individual applications and system management interface. + +Generally, in-process knowledge is available only to the process +itself; thus, unlike service-level organization of processes, +categorizing threads of a process requires active participation from +the application which owns the target process. + +cgroup v1 had an ambiguously defined delegation model which got abused +in combination with thread granularity. cgroups were delegated to +individual applications so that they can create and manage their own +sub-hierarchies and control resource distributions along them. This +effectively raised cgroup to the status of a syscall-like API exposed +to lay programs. + +First of all, cgroup has a fundamentally inadequate interface to be +exposed this way. For a process to access its own knobs, it has to +extract the path on the target hierarchy from /proc/self/cgroup, +construct the path by appending the name of the knob to the path, open +and then read and/or write to it. This is not only extremely clunky +and unusual but also inherently racy. There is no conventional way to +define transaction across the required steps and nothing can guarantee +that the process would actually be operating on its own sub-hierarchy. + +cgroup controllers implemented a number of knobs which would never be +accepted as public APIs because they were just adding control knobs to +system-management pseudo filesystem. cgroup ended up with interface +knobs which were not properly abstracted or refined and directly +revealed kernel internal details. These knobs got exposed to +individual applications through the ill-defined delegation mechanism +effectively abusing cgroup as a shortcut to implementing public APIs +without going through the required scrutiny. + +This was painful for both userland and kernel. Userland ended up with +misbehaving and poorly abstracted interfaces and kernel exposing and +locked into constructs inadvertently. + + +R-3. Competition Between Inner Nodes and Threads + +cgroup v1 allowed threads to be in any cgroups which created an +interesting problem where threads belonging to a parent cgroup and its +children cgroups competed for resources. This was nasty as two +different types of entities competed and there was no obvious way to +settle it. Different controllers did different things. + +The cpu controller considered threads and cgroups as equivalents and +mapped nice levels to cgroup weights. This worked for some cases but +fell flat when children wanted to be allocated specific ratios of CPU +cycles and the number of internal threads fluctuated - the ratios +constantly changed as the number of competing entities fluctuated. +There also were other issues. The mapping from nice level to weight +wasn't obvious or universal, and there were various other knobs which +simply weren't available for threads. + +The io controller implicitly created a hidden leaf node for each +cgroup to host the threads. The hidden leaf had its own copies of all +the knobs with "leaf_" prefixed. While this allowed equivalent +control over internal threads, it was with serious drawbacks. It +always added an extra layer of nesting which wouldn't be necessary +otherwise, made the interface messy and significantly complicated the +implementation. + +The memory controller didn't have a way to control what happened +between internal tasks and child cgroups and the behavior was not +clearly defined. There were attempts to add ad-hoc behaviors and +knobs to tailor the behavior to specific workloads which would have +led to problems extremely difficult to resolve in the long term. + +Multiple controllers struggled with internal tasks and came up with +different ways to deal with it; unfortunately, all the approaches were +severely flawed and, furthermore, the widely different behaviors +made cgroup as a whole highly inconsistent. + +This clearly is a problem which needs to be addressed from cgroup core +in a uniform way. + + +R-4. Other Interface Issues + +cgroup v1 grew without oversight and developed a large number of +idiosyncrasies and inconsistencies. One issue on the cgroup core side +was how an empty cgroup was notified - a userland helper binary was +forked and executed for each event. The event delivery wasn't +recursive or delegatable. The limitations of the mechanism also led +to in-kernel event delivery filtering mechanism further complicating +the interface. + +Controller interfaces were problematic too. An extreme example is +controllers completely ignoring hierarchical organization and treating +all cgroups as if they were all located directly under the root +cgroup. Some controllers exposed a large amount of inconsistent +implementation details to userland. + +There also was no consistency across controllers. When a new cgroup +was created, some controllers defaulted to not imposing extra +restrictions while others disallowed any resource usage until +explicitly configured. Configuration knobs for the same type of +control used widely differing naming schemes and formats. Statistics +and information knobs were named arbitrarily and used different +formats and units even in the same controller. + +cgroup v2 establishes common conventions where appropriate and updates +controllers so that they expose minimal and consistent interfaces. + + +R-5. Controller Issues and Remedies + +R-5-1. Memory + +The original lower boundary, the soft limit, is defined as a limit +that is per default unset. As a result, the set of cgroups that +global reclaim prefers is opt-in, rather than opt-out. The costs for +optimizing these mostly negative lookups are so high that the +implementation, despite its enormous size, does not even provide the +basic desirable behavior. First off, the soft limit has no +hierarchical meaning. All configured groups are organized in a global +rbtree and treated like equal peers, regardless where they are located +in the hierarchy. This makes subtree delegation impossible. Second, +the soft limit reclaim pass is so aggressive that it not just +introduces high allocation latencies into the system, but also impacts +system performance due to overreclaim, to the point where the feature +becomes self-defeating. + +The memory.low boundary on the other hand is a top-down allocated +reserve. A cgroup enjoys reclaim protection when it and all its +ancestors are below their low boundaries, which makes delegation of +subtrees possible. Secondly, new cgroups have no reserve per default +and in the common case most cgroups are eligible for the preferred +reclaim pass. This allows the new low boundary to be efficiently +implemented with just a minor addition to the generic reclaim code, +without the need for out-of-band data structures and reclaim passes. +Because the generic reclaim code considers all cgroups except for the +ones running low in the preferred first reclaim pass, overreclaim of +individual groups is eliminated as well, resulting in much better +overall workload performance. + +The original high boundary, the hard limit, is defined as a strict +limit that can not budge, even if the OOM killer has to be called. +But this generally goes against the goal of making the most out of the +available memory. The memory consumption of workloads varies during +runtime, and that requires users to overcommit. But doing that with a +strict upper limit requires either a fairly accurate prediction of the +working set size or adding slack to the limit. Since working set size +estimation is hard and error prone, and getting it wrong results in +OOM kills, most users tend to err on the side of a looser limit and +end up wasting precious resources. + +The memory.high boundary on the other hand can be set much more +conservatively. When hit, it throttles allocations by forcing them +into direct reclaim to work off the excess, but it never invokes the +OOM killer. As a result, a high boundary that is chosen too +aggressively will not terminate the processes, but instead it will +lead to gradual performance degradation. The user can monitor this +and make corrections until the minimal memory footprint that still +gives acceptable performance is found. + +In extreme cases, with many concurrent allocations and a complete +breakdown of reclaim progress within the group, the high boundary can +be exceeded. But even then it's mostly better to satisfy the +allocation from the slack available in other groups or the rest of the +system than killing the group. Otherwise, memory.max is there to +limit this type of spillover and ultimately contain buggy or even +malicious applications. + +The combined memory+swap accounting and limiting is replaced by real +control over swap space. + +The main argument for a combined memory+swap facility in the original +cgroup design was that global or parental pressure would always be +able to swap all anonymous memory of a child group, regardless of the +child's own (possibly untrusted) configuration. However, untrusted +groups can sabotage swapping by other means - such as referencing its +anonymous memory in a tight loop - and an admin can not assume full +swappability when overcommitting untrusted jobs. + +For trusted jobs, on the other hand, a combined counter is not an +intuitive userspace interface, and it flies in the face of the idea +that cgroup controllers should account and limit specific physical +resources. Swap space is a resource like all others in the system, +and that's why unified hierarchy allows distributing it separately. diff --git a/Documentation/cgroups/unified-hierarchy.txt b/Documentation/cgroups/unified-hierarchy.txt deleted file mode 100644 index 781b1d475bcfc9666d0d3dad80832c74adb48b22..0000000000000000000000000000000000000000 --- a/Documentation/cgroups/unified-hierarchy.txt +++ /dev/null @@ -1,647 +0,0 @@ - -Cgroup unified hierarchy - -April, 2014 Tejun Heo - -This document describes the changes made by unified hierarchy and -their rationales.

For example, a given configuration might not care about -how memory is distributed beyond a certain level while still wanting -to control how CPU cycles are distributed. - -Unified hierarchy is the next version of cgroup interface. It aims to -address the aforementioned issues by having more structure while -retaining enough flexibility for most use cases. Various other -general and controller-specific interface issues are also addressed in -the process. - - -2. Basic Operation - -2-1. Mounting - -Currently, unified hierarchy can be mounted with the following mount -command. Note that this is still under development and scheduled to -change soon. - - mount -t cgroup -o __DEVEL__sane_behavior cgroup $MOUNT_POINT - -All controllers which support the unified hierarchy and are not bound -to other hierarchies are automatically bound to unified hierarchy and -show up at the root of it. Controllers which are enabled only in the -root of unified hierarchy can be bound to other hierarchies. This -allows mixing unified hierarchy with the traditional multiple -hierarchies in a fully backward compatible way. - -A controller can be moved across hierarchies only after the controller -is no longer referenced in its current hierarchy. Because per-cgroup -controller states are destroyed asynchronously and controllers may -have lingering references, a controller may not show up immediately on -the unified hierarchy after the final umount of the previous -hierarchy. Similarly, a controller should be fully disabled to be -moved out of the unified hierarchy and it may take some time for the -disabled controller to become available for other hierarchies; -furthermore, due to dependencies among controllers, other controllers -may need to be disabled too. - -While useful for development and manual configurations, dynamically -moving controllers between the unified and other hierarchies is -strongly discouraged for production use. It is recommended to decide -the hierarchies and controller associations before starting using the -controllers. - - -2-2. cgroup.subtree_control - -All cgroups on unified hierarchy have a "cgroup.subtree_control" file -which governs which controllers are enabled on the children of the -cgroup. Let's assume a hierarchy like the following. - - root - A - B - C - \ D - -root's "cgroup.subtree_control" file determines which controllers are -enabled on A. A's on B. B's on C and D. This coincides with the -fact that controllers on the immediate sub-level are used to -distribute the resources of the parent. In fact, it's natural to -assume that resource control knobs of a child belong to its parent. -Enabling a controller in a "cgroup.subtree_control" file declares that -distribution of the respective resources of the cgroup will be -controlled. Note that this means that controller enable states are -shared among siblings. - -When read, the file contains a space-separated list of currently -enabled controllers. A write to the file should contain a -space-separated list of controllers with '+' or '-' prefixed (without -the quotes). Controllers prefixed with '+' are enabled and '-' -disabled. If a controller is listed multiple times, the last entry -wins. The specific operations are executed atomically - either all -succeed or fail. - - -2-3. cgroup.controllers - -Read-only "cgroup.controllers" file contains a space-separated list of -controllers which can be enabled in the cgroup's -"cgroup.subtree_control" file. - -In the root cgroup, this lists controllers which are not bound to -other hierarchies and the content changes as controllers are bound to -and unbound from other hierarchies. - -In non-root cgroups, the content of this file equals that of the -parent's "cgroup.subtree_control" file as only controllers enabled -from the parent can be used in its children. - - -3. Structural Constraints - -3-1. Top-down - -As it doesn't make sense to nest control of an uncontrolled resource, -all non-root "cgroup.subtree_control" files can only contain -controllers which are enabled in the parent's "cgroup.subtree_control" -file. A controller can be enabled only if the parent has the -controller enabled and a controller can't be disabled if one or more -children have it enabled. - - -3-2. No internal tasks - -One long-standing issue that cgroup faces is the competition between -tasks belonging to the parent cgroup and its children cgroups. This -is inherently nasty as two different types of entities compete and -there is no agreed-upon obvious way to handle it. Different -controllers are doing different things. - -The cpu controller considers tasks and cgroups as equivalents and maps -nice levels to cgroup weights. This works for some cases but falls -flat when children should be allocated specific ratios of CPU cycles -and the number of internal tasks fluctuates - the ratios constantly -change as the number of competing entities fluctuates. There also are -other issues. The mapping from nice level to weight isn't obvious or -universal, and there are various other knobs which simply aren't -available for tasks. - -The io controller implicitly creates a hidden leaf node for each -cgroup to host the tasks. The hidden leaf has its own copies of all -the knobs with "leaf_" prefixed. While this allows equivalent control -over internal tasks, it's with serious drawbacks. It always adds an -extra layer of nesting which may not be necessary, makes the interface -messy and significantly complicates the implementation. - -The memory controller currently doesn't have a way to control what -happens between internal tasks and child cgroups and the behavior is -not clearly defined. There have been attempts to add ad-hoc behaviors -and knobs to tailor the behavior to specific workloads. Continuing -this direction will lead to problems which will be extremely difficult -to resolve in the long term. - -Multiple controllers struggle with internal tasks and came up with -different ways to deal with it; unfortunately, all the approaches in -use now are severely flawed and, furthermore, the widely different -behaviors make cgroup as whole highly inconsistent. - -It is clear that this is something which needs to be addressed from -cgroup core proper in a uniform way so that controllers don't need to -worry about it and cgroup as a whole shows a consistent and logical -behavior. To achieve that, unified hierarchy enforces the following -structural constraint: - - Except for the root, only cgroups which don't contain any task may - have controllers enabled in their "cgroup.subtree_control" files. - -Combined with other properties, this guarantees that, when a -controller is looking at the part of the hierarchy which has it -enabled, tasks are always only on the leaves. This rules out -situations where child cgroups compete against internal tasks of the -parent. - -There are two things to note. Firstly, the root cgroup is exempt from -the restriction. Root contains tasks and anonymous resource -consumption which can't be associated with any other cgroup and -requires special treatment from most controllers. How resource -consumption in the root cgroup is governed is up to each controller. - -Secondly, the restriction doesn't take effect if there is no enabled -controller in the cgroup's "cgroup.subtree_control" file. This is -important as otherwise it wouldn't be possible to create children of a -populated cgroup. To control resource distribution of a cgroup, the -cgroup must create children and transfer all its tasks to the children -before enabling controllers in its "cgroup.subtree_control" file. - - -4. Delegation - -4-1. Model of delegation - -A cgroup can be delegated to a less privileged user by granting write -access of the directory and its "cgroup.procs" file to the user. Note -that the resource control knobs in a given directory concern the -resources of the parent and thus must not be delegated along with the -directory. - -Once delegated, the user can build sub-hierarchy under the directory, -organize processes as it sees fit and further distribute the resources -it got from the parent. The limits and other settings of all resource -controllers are hierarchical and regardless of what happens in the -delegated sub-hierarchy, nothing can escape the resource restrictions -imposed by the parent. - -Currently, cgroup doesn't impose any restrictions on the number of -cgroups in or nesting depth of a delegated sub-hierarchy; however, -this may in the future be limited explicitly. - - -4-2. Common ancestor rule - -On the unified hierarchy, to write to a "cgroup.procs" file, in -addition to the usual write permission to the file and uid match, the -writer must also have write access to the "cgroup.procs" file of the -common ancestor of the source and destination cgroups. This prevents -delegatees from smuggling processes across disjoint sub-hierarchies. - -Let's say cgroups C0 and C1 have been delegated to user U0 who created -C00, C01 under C0 and C10 under C1 as follows. - - ~~~~~~~~~~~~~ - C0 - C00 - ~ cgroup ~ \ C01 - ~ hierarchy ~ - ~~~~~~~~~~~~~ - C1 - C10 - -C0 and C1 are separate entities in terms of resource distribution -regardless of their relative positions in the hierarchy. The -resources the processes under C0 are entitled to are controlled by -C0's ancestors and may be completely different from C1. It's clear -that the intention of delegating C0 to U0 is allowing U0 to organize -the processes under C0 and further control the distribution of C0's -resources. - -On traditional hierarchies, if a task has write access to "tasks" or -"cgroup.procs" file of a cgroup and its uid agrees with the target, it -can move the target to the cgroup. In the above example, U0 will not -only be able to move processes in each sub-hierarchy but also across -the two sub-hierarchies, effectively allowing it to violate the -organizational and resource restrictions implied by the hierarchical -structure above C0 and C1. - -On the unified hierarchy, let's say U0 wants to write the pid of a -process which has a matching uid and is currently in C10 into -"C00/cgroup.procs". U0 obviously has write access to the file and -migration permission on the process; however, the common ancestor of -the source cgroup C10 and the destination cgroup C00 is above the -points of delegation and U0 would not have write access to its -"cgroup.procs" and thus be denied with -EACCES. - - -5. Other Changes - -5-1. [Un]populated Notification - -cgroup users often need a way to determine when a cgroup's -subhierarchy becomes empty so that it can be cleaned up. cgroup -currently provides release_agent for it; unfortunately, this mechanism -is riddled with issues. - -- It delivers events by forking and execing a userland binary - specified as the release_agent. This is a long deprecated method of - notification delivery. It's extremely heavy, slow and cumbersome to - integrate with larger infrastructure. - -- There is single monitoring point at the root. There's no way to - delegate management of a subtree. - -- The event isn't recursive. It triggers when a cgroup doesn't have - any tasks or child cgroups. Events for internal nodes trigger only - after all children are removed. This again makes it impossible to - delegate management of a subtree. - -- Events are filtered from the kernel side. A "notify_on_release" - file is used to subscribe to or suppress release events. This is - unnecessarily complicated and probably done this way because event - delivery itself was expensive. - -Unified hierarchy implements "populated" field in "cgroup.events" -interface file which can be used to monitor whether the cgroup's -subhierarchy has tasks in it or not. Its value is 0 if there is no -task in the cgroup and its descendants; otherwise, 1. poll and -[id]notify events are triggered when the value changes. - -This is significantly lighter and simpler and trivially allows -delegating management of subhierarchy - subhierarchy monitoring can -block further propagation simply by putting itself or another process -in the subhierarchy and monitor events that it's interested in from -there without interfering with monitoring higher in the tree. - -In unified hierarchy, the release_agent mechanism is no longer -supported and the interface files "release_agent" and -"notify_on_release" do not exist. - - -5-2. Other Core Changes - -- None of the mount options is allowed. - -- remount is disallowed. - -- rename(2) is disallowed. - -- The "tasks" file is removed. Everything should at process - granularity. Use the "cgroup.procs" file instead. - -- The "cgroup.procs" file is not sorted. pids will be unique unless - they got recycled in-between reads. - -- The "cgroup.clone_children" file is removed. - -- /proc/PID/cgroup keeps reporting the cgroup that a zombie belonged - to before exiting. If the cgroup is removed before the zombie is - reaped, " (deleted)" is appeneded to the path. - - -5-3. Controller File Conventions - -5-3-1. Format - -In general, all controller files should be in one of the following -formats whenever possible. - -- Values only files - - VAL0 VAL1...\n - -- Flat keyed files - - KEY0 VAL0\n - KEY1 VAL1\n - ... - -- Nested keyed files - - KEY0 SUB_KEY0=VAL00 SUB_KEY1=VAL01... - KEY1 SUB_KEY0=VAL10 SUB_KEY1=VAL11... - ... - -For a writeable file, the format for writing should generally match -reading; however, controllers may allow omitting later fields or -implement restricted shortcuts for most common use cases. - -For both flat and nested keyed files, only the values for a single key -can be written at a time. For nested keyed files, the sub key pairs -may be specified in any order and not all pairs have to be specified. - - -5-3-2. Control Knobs - -- Settings for a single feature should generally be implemented in a - single file. - -- In general, the root cgroup should be exempt from resource control - and thus shouldn't have resource control knobs. - -- If a controller implements ratio based resource distribution, the - control knob should be named "weight" and have the range [1, 10000] - and 100 should be the default value. The values are chosen to allow - enough and symmetric bias in both directions while keeping it - intuitive (the default is 100%). - -- If a controller implements an absolute resource guarantee and/or - limit, the control knobs should be named "min" and "max" - respectively. If a controller implements best effort resource - gurantee and/or limit, the control knobs should be named "low" and - "high" respectively. - - In the above four control files, the special token "max" should be - used to represent upward infinity for both reading and writing. - -- If a setting has configurable default value and specific overrides, - the default settings should be keyed with "default" and appear as - the first entry in the file. Specific entries can use "default" as - its value to indicate inheritance of the default value. - -- For events which are not very high frequency, an interface file - "events" should be created which lists event key value pairs. - Whenever a notifiable event happens, file modified event should be - generated on the file. - - -5-4. Per-Controller Changes - -5-4-1. io - -- blkio is renamed to io. The interface is overhauled anyway. The - new name is more in line with the other two major controllers, cpu - and memory, and better suited given that it may be used for cgroup - writeback without involving block layer. - -- Everything including stat is always hierarchical making separate - recursive stat files pointless and, as no internal node can have - tasks, leaf weights are meaningless. The operation model is - simplified and the interface is overhauled accordingly. - - io.stat - - The stat file. The reported stats are from the point where - bio's are issued to request_queue. The stats are counted - independent of which policies are enabled. Each line in the - file follows the following format. More fields may later be - added at the end. - - $MAJ:$MIN rbytes=$RBYTES wbytes=$WBYTES rios=$RIOS wrios=$WIOS - - io.weight - - The weight setting, currently only available and effective if - cfq-iosched is in use for the target device. The weight is - between 1 and 10000 and defaults to 100. The first line - always contains the default weight in the following format to - use when per-device setting is missing. - - default $WEIGHT - - Subsequent lines list per-device weights of the following - format. - - $MAJ:$MIN $WEIGHT - - Writing "$WEIGHT" or "default $WEIGHT" changes the default - setting. Writing "$MAJ:$MIN $WEIGHT" sets per-device weight - while "$MAJ:$MIN default" clears it. - - This file is available only on non-root cgroups. - - io.max - - The maximum bandwidth and/or iops setting, only available if - blk-throttle is enabled. The file is of the following format. - - $MAJ:$MIN rbps=$RBPS wbps=$WBPS riops=$RIOPS wiops=$WIOPS - - ${R|W}BPS are read/write bytes per second and ${R|W}IOPS are - read/write IOs per second. "max" indicates no limit. Writing - to the file follows the same format but the individual - settings may be omitted or specified in any order. - - This file is available only on non-root cgroups. - - -5-4-2. cpuset - -- Tasks are kept in empty cpusets after hotplug and take on the masks - of the nearest non-empty ancestor, instead of being moved to it. - -- A task can be moved into an empty cpuset, and again it takes on the - masks of the nearest non-empty ancestor. - - -5-4-3. memory - -- use_hierarchy is on by default and the cgroup file for the flag is - not created. - -- The original lower boundary, the soft limit, is defined as a limit - that is per default unset. As a result, the set of cgroups that - global reclaim prefers is opt-in, rather than opt-out. The costs - for optimizing these mostly negative lookups are so high that the - implementation, despite its enormous size, does not even provide the - basic desirable behavior. First off, the soft limit has no - hierarchical meaning. All configured groups are organized in a - global rbtree and treated like equal peers, regardless where they - are located in the hierarchy. This makes subtree delegation - impossible. Second, the soft limit reclaim pass is so aggressive - that it not just introduces high allocation latencies into the - system, but also impacts system performance due to overreclaim, to - the point where the feature becomes self-defeating. - - The memory.low boundary on the other hand is a top-down allocated - reserve. A cgroup enjoys reclaim protection when it and all its - ancestors are below their low boundaries, which makes delegation of - subtrees possible. Secondly, new cgroups have no reserve per - default and in the common case most cgroups are eligible for the - preferred reclaim pass. This allows the new low boundary to be - efficiently implemented with just a minor addition to the generic - reclaim code, without the need for out-of-band data structures and - reclaim passes. Because the generic reclaim code considers all - cgroups except for the ones running low in the preferred first - reclaim pass, overreclaim of individual groups is eliminated as - well, resulting in much better overall workload performance. - -- The original high boundary, the hard limit, is defined as a strict - limit that can not budge, even if the OOM killer has to be called. - But this generally goes against the goal of making the most out of - the available memory. The memory consumption of workloads varies - during runtime, and that requires users to overcommit. But doing - that with a strict upper limit requires either a fairly accurate - prediction of the working set size or adding slack to the limit. - Since working set size estimation is hard and error prone, and - getting it wrong results in OOM kills, most users tend to err on the - side of a looser limit and end up wasting precious resources. - - The memory.high boundary on the other hand can be set much more - conservatively. When hit, it throttles allocations by forcing them - into direct reclaim to work off the excess, but it never invokes the - OOM killer. As a result, a high boundary that is chosen too - aggressively will not terminate the processes, but instead it will - lead to gradual performance degradation. The user can monitor this - and make corrections until the minimal memory footprint that still - gives acceptable performance is found. - - In extreme cases, with many concurrent allocations and a complete - breakdown of reclaim progress within the group, the high boundary - can be exceeded. But even then it's mostly better to satisfy the - allocation from the slack available in other groups or the rest of - the system than killing the group. Otherwise, memory.max is there - to limit this type of spillover and ultimately contain buggy or even - malicious applications. - -- The original control file names are unwieldy and inconsistent in - many different ways. For example, the upper boundary hit count is - exported in the memory.failcnt file, but an OOM event count has to - be manually counted by listening to memory.oom_control events, and - lower boundary / soft limit events have to be counted by first - setting a threshold for that value and then counting those events. - Also, usage and limit files encode their units in the filename. - That makes the filenames very long, even though this is not - information that a user needs to be reminded of every time they type - out those names. - - To address these naming issues, as well as to signal clearly that - the new interface carries a new configuration model, the naming - conventions in it necessarily differ from the old interface. - -- The original limit files indicate the state of an unset limit with a - Very High Number, and a configured limit can be unset by echoing -1 - into those files. But that very high number is implementation and - architecture dependent and not very descriptive. And while -1 can - be understood as an underflow into the highest possible value, -2 or - -10M etc. do not work, so it's not consistent. - - memory.low, memory.high, and memory.max will use the string "max" to - indicate and set the highest possible value. - -6. Planned Changes - -6-1. CAP for resource control - -Unified hierarchy will require one of the capabilities(7), which is -yet to be decided, for all resource control related knobs. Process -organization operations - creation of sub-cgroups and migration of -processes in sub-hierarchies may be delegated by changing the -ownership and/or permissions on the cgroup directory and -"cgroup.procs" interface file; however, all operations which affect -resource control - writes to a "cgroup.subtree_control" file or any -controller-specific knobs - will require an explicit CAP privilege. - -This, in part, is to prevent the cgroup interface from being -inadvertently promoted to programmable API used by non-privileged -binaries. cgroup exposes various aspects of the system in ways which -aren't properly abstracted for direct consumption by regular programs. -This is an administration interface much closer to sysctl knobs than -system calls. Even the basic access model, being filesystem path -based, isn't suitable for direct consumption. There's no way to -access "my cgroup" in a race-free way or make multiple operations -atomic against migration to another cgroup. - -Another aspect is that, for better or for worse, the cgroup interface -goes through far less scrutiny than regular interfaces for -unprivileged userland. The upside is that cgroup is able to expose -useful features which may not be suitable for general consumption in a -reasonable time frame. It provides a relatively short path between -internal details and userland-visible interface. Of course, this -shortcut comes with high risk. We go through what we go through for -general kernel APIs for good reasons. It may end up leaking internal -details in a way which can exert significant pain by locking the -kernel into a contract that can't be maintained in a reasonable -manner. - -Also, due to the specific nature, cgroup and its controllers don't -tend to attract attention from a wide scope of developers. cgroup's -short history is already fraught with severely mis-designed -interfaces, unnecessary commitments to and exposing of internal -details, broken and dangerous implementations of various features. - -Keeping cgroup as an administration interface is both advantageous for -its role and imperative given its nature. Some of the cgroup features -may make sense for unprivileged access. If deemed justified, those -must be further abstracted and implemented as a different interface, -be it a system call or process-private filesystem, and survive through -the scrutiny that any interface for general consumption is required to -go through. - -Requiring CAP is not a complete solution but should serve as a -significant deterrent against spraying cgroup usages in non-privileged -programs. diff --git a/Documentation/cpu-freq/intel-pstate.txt b/Documentation/cpu-freq/intel-pstate.txt index be8d4006bf767d37b7b1882ba962363abb1f81d3..f7b12c071d5356ceed76231a07b4e49f59e9f8d8 100644 --- a/Documentation/cpu-freq/intel-pstate.txt +++ b/Documentation/cpu-freq/intel-pstate.txt @@ -1,61 +1,131 @@ -Intel P-state driver +Intel P-State driver -------------------- -This driver provides an interface to control the P state selection for -SandyBridge+ Intel processors.

For example: a platform with hierarchy of three levels + of versions (A, B and C), this field should be like , where X + corresponds to Version hierarchy A, Y corresponds to version hierarchy B and Z + corresponds to version hierarchy C. + + Each level of hierarchy is represented by a 32 bit value, and so there can be + only 32 different supported version per hierarchy. i.e. 1 bit per version. A + value of 0xFFFFFFFF will enable the OPP for all versions for that hierarchy + level. And a value of 0x00000000 will disable the OPP completely, and so we + never want that to happen. + + If 32 values aren't sufficient for a version hierarchy, than that version + hierarchy can be contained in multiple 32 bit values. i.e. in the + above example, Z1 & Z2 refer to the version hierarchy Z. + - status: Marks the node enabled/disabled.

Allocation of the structure is handled by the -media device driver, usually by embedding the media_device instance in a -larger driver-specific structure. - -Drivers register media device instances by calling - - media_device_register(struct media_device *mdev); - -The caller is responsible for initializing the media_device structure before -registration. The following fields must be set: - - - dev must point to the parent device (usually a pci_dev, usb_interface or - platform_device instance). - - - model must be filled with the device model name as a NUL-terminated UTF-8 - string. The device/model revision must not be stored in this field. - -The following fields are optional: - - - serial is a unique serial number stored as a NUL-terminated ASCII string. - The field is big enough to store a GUID in text form. If the hardware - doesn't provide a unique serial number this field must be left empty. - - - bus_info represents the location of the device in the system as a - NUL-terminated ASCII string. For PCI/PCIe devices bus_info must be set to - "PCI:" (or "PCIe:") followed by the value of pci_name(). For USB devices, - the usb_make_path() function must be used. This field is used by - applications to distinguish between otherwise identical devices that don't - provide a serial number. - - - hw_revision is the hardware device revision in a driver-specific format. - When possible the revision should be formatted with the KERNEL_VERSION - macro. - - - driver_version is formatted with the KERNEL_VERSION macro. The version - minor must be incremented when new features are added to the userspace API - without breaking binary compatibility. The version major must be - incremented when binary compatibility is broken. - -Upon successful registration a character device named media[0-9]+ is created. -The device major and minor numbers are dynamic. The model name is exported as -a sysfs attribute. - -Drivers unregister media device instances by calling - - media_device_unregister(struct media_device *mdev); - -Unregistering a media device that hasn't been registered is *NOT* safe. - - -Entities, pads and links ------------------------- - -- Entities - -Entities are represented by a struct media_entity instance, defined in -include/media/media-entity.h. The structure is usually embedded into a -higher-level structure, such as a v4l2_subdev or video_device instance, -although drivers can allocate entities directly. - -Drivers initialize entities by calling - - media_entity_init(struct media_entity *entity, u16 num_pads, - struct media_pad *pads, u16 extra_links); - -The media_entity name, type, flags, revision and group_id fields can be -initialized before or after calling media_entity_init. Entities embedded in -higher-level standard structures can have some of those fields set by the -higher-level framework. - -As the number of pads is known in advance, the pads array is not allocated -dynamically but is managed by the entity driver. Most drivers will embed the -pads array in a driver-specific structure, avoiding dynamic allocation. - -Drivers must set the direction of every pad in the pads array before calling -media_entity_init. The function will initialize the other pads fields. - -Unlike the number of pads, the total number of links isn't always known in -advance by the entity driver. As an initial estimate, media_entity_init -pre-allocates a number of links equal to the number of pads plus an optional -number of extra links. The links array will be reallocated if it grows beyond -the initial estimate. - -Drivers register entities with a media device by calling - - media_device_register_entity(struct media_device *mdev, - struct media_entity *entity); - -Entities are identified by a unique positive integer ID. Drivers can provide an -ID by filling the media_entity id field prior to registration, or request the -media controller framework to assign an ID automatically. Drivers that provide -IDs manually must ensure that all IDs are unique. IDs are not guaranteed to be -contiguous even when they are all assigned automatically by the framework. - -Drivers unregister entities by calling - - media_device_unregister_entity(struct media_entity *entity); - -Unregistering an entity will not change the IDs of the other entities, and the -ID will never be reused for a newly registered entity. - -When a media device is unregistered, all its entities are unregistered -automatically. No manual entities unregistration is then required. - -Drivers free resources associated with an entity by calling - - media_entity_cleanup(struct media_entity *entity); - -This function must be called during the cleanup phase after unregistering the -entity. Note that the media_entity instance itself must be freed explicitly by -the driver if required. - -Entities have flags that describe the entity capabilities and state. - - MEDIA_ENT_FL_DEFAULT indicates the default entity for a given type. - This can be used to report the default audio and video devices or the - default camera sensor. - -Logical entity groups can be defined by setting the group ID of all member -entities to the same non-zero value. An entity group serves no purpose in the -kernel, but is reported to userspace during entities enumeration. The group_id -field belongs to the media device driver and must not by touched by entity -drivers. - -Media device drivers should define groups if several entities are logically -bound together. Example usages include reporting - - - ALSA, VBI and video nodes that carry the same media stream - - lens and flash controllers associated with a sensor - -- Pads - -Pads are represented by a struct media_pad instance, defined in -include/media/media-entity.h. Each entity stores its pads in a pads array -managed by the entity driver. Drivers usually embed the array in a -driver-specific structure. - -Pads are identified by their entity and their 0-based index in the pads array. -Both information are stored in the media_pad structure, making the media_pad -pointer the canonical way to store and pass link references. - -Pads have flags that describe the pad capabilities and state. - - MEDIA_PAD_FL_SINK indicates that the pad supports sinking data. - MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data. - -One and only one of MEDIA_PAD_FL_SINK and MEDIA_PAD_FL_SOURCE must be set for -each pad. - -- Links - -Links are represented by a struct media_link instance, defined in -include/media/media-entity.h. Each entity stores all links originating at or -targeting any of its pads in a links array. A given link is thus stored -twice, once in the source entity and once in the target entity. The array is -pre-allocated and grows dynamically as needed. - -Drivers create links by calling - - media_entity_create_link(struct media_entity *source, u16 source_pad, - struct media_entity *sink, u16 sink_pad, - u32 flags); - -An entry in the link array of each entity is allocated and stores pointers -to source and sink pads. - -Links have flags that describe the link capabilities and state. - - MEDIA_LNK_FL_ENABLED indicates that the link is enabled and can be used - to transfer media data. When two or more links target a sink pad, only - one of them can be enabled at a time. - MEDIA_LNK_FL_IMMUTABLE indicates that the link enabled state can't be - modified at runtime. If MEDIA_LNK_FL_IMMUTABLE is set, then - MEDIA_LNK_FL_ENABLED must also be set since an immutable link is always - enabled. - - -Graph traversal ---------------- - -The media framework provides APIs to iterate over entities in a graph. - -To iterate over all entities belonging to a media device, drivers can use the -media_device_for_each_entity macro, defined in include/media/media-device.h. - - struct media_entity *entity; - - media_device_for_each_entity(entity, mdev) { - /* entity will point to each entity in turn */ - ... - } - -Drivers might also need to iterate over all entities in a graph that can be -reached only through enabled links starting at a given entity. The media -framework provides a depth-first graph traversal API for that purpose. - -Note that graphs with cycles (whether directed or undirected) are *NOT* -supported by the graph traversal API. To prevent infinite loops, the graph -traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH, -currently defined as 16. - -Drivers initiate a graph traversal by calling - - media_entity_graph_walk_start(struct media_entity_graph *graph, - struct media_entity *entity); - -The graph structure, provided by the caller, is initialized to start graph -traversal at the given entity. - -Drivers can then retrieve the next entity by calling - - media_entity_graph_walk_next(struct media_entity_graph *graph); - -When the graph traversal is complete the function will return NULL. - -Graph traversal can be interrupted at any moment. No cleanup function call is -required and the graph structure can be freed normally. - -Helper functions can be used to find a link between two given pads, or a pad -connected to another pad through an enabled link - - media_entity_find_link(struct media_pad *source, - struct media_pad *sink); - - media_entity_remote_pad(struct media_pad *pad); - -Refer to the kerneldoc documentation for more information. - - -Use count and power handling ----------------------------- - -Due to the wide differences between drivers regarding power management needs, -the media controller does not implement power management. However, the -media_entity structure includes a use_count field that media drivers can use to -track the number of users of every entity for power management needs. - -The use_count field is owned by media drivers and must not be touched by entity -drivers. Access to the field must be protected by the media device graph_mutex -lock. - - -Links setup ------------ - -Link properties can be modified at runtime by calling - - media_entity_setup_link(struct media_link *link, u32 flags); - -The flags argument contains the requested new link flags. - -The only configurable property is the ENABLED link flag to enable/disable a -link. Links marked with the IMMUTABLE link flag can not be enabled or disabled. - -When a link is enabled or disabled, the media framework calls the -link_setup operation for the two entities at the source and sink of the link, -in that order. If the second link_setup call fails, another link_setup call is -made on the first entity to restore the original link flags. - -Media device drivers can be notified of link setup operations by setting the -media_device::link_notify pointer to a callback function. If provided, the -notification callback will be called before enabling and after disabling -links. - -Entity drivers must implement the link_setup operation if any of their links -is non-immutable. The operation must either configure the hardware or store -the configuration information to be applied later. - -Link configuration must not have any side effect on other links. If an enabled -link at a sink pad prevents another link at the same pad from being enabled, -the link_setup operation must return -EBUSY and can't implicitly disable the -first enabled link. - - -Pipelines and media streams ---------------------------- - -When starting streaming, drivers must notify all entities in the pipeline to -prevent link states from being modified during streaming by calling - - media_entity_pipeline_start(struct media_entity *entity, - struct media_pipeline *pipe); - -The function will mark all entities connected to the given entity through -enabled links, either directly or indirectly, as streaming. - -The media_pipeline instance pointed to by the pipe argument will be stored in -every entity in the pipeline. Drivers should embed the media_pipeline structure -in higher-level pipeline structures and can then access the pipeline through -the media_entity pipe field. - -Calls to media_entity_pipeline_start() can be nested. The pipeline pointer must -be identical for all nested calls to the function. - -media_entity_pipeline_start() may return an error. In that case, it will -clean up any of the changes it did by itself. - -When stopping the stream, drivers must notify the entities with - - media_entity_pipeline_stop(struct media_entity *entity); - -If multiple calls to media_entity_pipeline_start() have been made the same -number of media_entity_pipeline_stop() calls are required to stop streaming. The -media_entity pipe field is reset to NULL on the last nested stop call. - -Link configuration will fail with -EBUSY by default if either end of the link is -a streaming entity. Links that can be modified while streaming must be marked -with the MEDIA_LNK_FL_DYNAMIC flag. - -If other operations need to be disallowed on streaming entities (such as -changing entities configuration parameters) drivers can explicitly check the -media_entity stream_count field to find out if an entity is streaming. This -operation must be done with the media_device graph_mutex held. - - -Link validation ---------------- - -Link validation is performed by media_entity_pipeline_start() for any -entity which has sink pads in the pipeline. The -media_entity::link_validate() callback is used for that purpose. In -link_validate() callback, entity driver should check that the properties of -the source pad of the connected entity and its own sink pad match.
