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 + "infinity" to indicate and set the highest possible value. 5.

Semantically they are somewhat like a +pthread_barriers and have similar use-cases. + +Completions are a code synchronization mechanism that is preferable to any +misuse of locks. Any time you think of using yield() or some quirky +msleep(1); loop to allow something else to proceed, you probably want to +look into using one of the wait_for_completion*() calls instead. The +advantage of using completions is clear intent of the code but also more +efficient code as both threads can continue until the result is actually +needed. + +Completions are built on top of the generic event infrastructure in Linux, +with the event reduced to a simple flag appropriately called "done" in +struct completion, that tells the waiting threads of execution if they +can continue safely. + +As completions are scheduling related the code is found in +kernel/sched/completion.c - for details on completion design and +implementation see completions-design.txt + + +Usage: +------ + +There are three parts to the using completions, the initialization of the +struct completion, the waiting part through a call to one of the variants of +wait_for_completion() and the signaling side through a call to complete(), +or complete_all(). Further there are some helper functions for checking the +state of completions. + +To use completions one needs to include and +create a variable of type struct completion. The structure used for +handling of completions is: + + struct completion { + unsigned int done; + wait_queue_head_t wait; + }; + +providing the wait queue to place tasks on for waiting and the flag for +indicating the state of affairs. + +Completions should be named to convey the intent of the waiter. A good +example is: + + wait_for_completion(&early_console_added); + + complete(&early_console_added); + +Good naming (as always) helps code readability. + + +Initializing completions: +------------------------- + +Initialization of dynamically allocated completions, often embedded in +other structures, is done with: + + void init_completion(&done); + +Initialization is accomplished by initializing the wait queue and setting +the default state to "not available", that is, "done" is set to 0. + +The re-initialization function, reinit_completion(), simply resets the +done element to "not available", thus again to 0, without touching the +wait queue. Calling init_completion() on the same completions object is +most likely a bug as it re-initializes the queue to an empty queue and +enqueued tasks could get "lost" - use reinit_completion() in that case. + +For static declaration and initialization, macros are available. These are: + + static DECLARE_COMPLETION(setup_done) + +used for static declarations in file scope. Within functions the static +initialization should always use: + + DECLARE_COMPLETION_ONSTACK(setup_done) + +suitable for automatic/local variables on the stack and will make lockdep +happy. Note also that one needs to making *sure* the completion passt to +work threads remains in-scope, and no references remain to on-stack data +when the initiating function returns. + + +Waiting for completions: +------------------------ + +For a thread of execution to wait for some concurrent work to finish, it +calls wait_for_completion() on the initialized completion structure. +A typical usage scenario is: + + structure completion setup_done; + init_completion(&setup_done); + initialze_work(...,&setup_done,...) + + /* run non-dependent code */ /* do setup */ + + wait_for_completion(&seupt_done); complete(setup_done) + +This is not implying any temporal order of wait_for_completion() and the +call to complete() - if the call to complete() happened before the call +to wait_for_completion() then the waiting side simply will continue +immediately as all dependencies are satisfied. + +Note that wait_for_completion() is calling spin_lock_irq/spin_unlock_irq +so it can only be called safely when you know that interrupts are enabled. +Calling it from hard-irq context will result in hard to detect spurious +enabling of interrupts. + +wait_for_completion(): + + void wait_for_completion(struct completion *done): + +The default behavior is to wait without a timeout and mark the task as +uninterruptible. wait_for_completion() and its variants are only safe +in soft-interrupt or process context but not in hard-irq context. +As all variants of wait_for_completion() can (obviously) block for a long +time, you probably don't want to call this with held locks - see also +try_wait_for_completion() below. + + +Variants available: +------------------- + +The below variants all return status and this status should be checked in +most(/all) cases - in cases where the status is deliberately not checked you +probably want to make a note explaining this (e.g. see +arch/arm/kernel/smp.c:__cpu_up()). + +A common problem that occurs is to have unclean assignment of return types, +so care should be taken with assigning return-values to variables of proper +type.
