From b755706cd726e5d465c28c2cd64c618419034981 Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Wed, 7 Dec 2011 11:47:40 -0800 Subject: [PATCH 0001/7995] ARM: OMAP2+: board-generic: Add missing handle_irq callbacks The following commit: 6b2f55d7851aa358d3a99cff344c560c4967f042, is adding the support for the CONFIG_MULTI_IRQ_HANDLER but did not update all the machine descriptors supported in the DT board-generic.c file. It thus break the DT boot on OMAP3 and OMAP4 boards. Add the proper handle_irq callbacks for OMAP3 and OMAP4 generic machine descriptors.

AFAIK only powerpc actually has a usable userspace read of the PMCs but I'm not at all sure anybody actually used that. ARM is restored to the default since it currently does not support userspace access at all. And all software events are provided with a method that reports their index as 0 (disabled).

The latch reset operation, which will be replaced with GPIO initialization, must also be moved to late_initcall for the same reason. Since there was already another, separate arch_initcall function for setting up one of those latch dependent devices, the on-board modem device, reuse that function, i.e., rename it to a name that matches the new purpose, extend with other device setup relocated from .machine_init, and move down to the late_initcall level. While being at it, add missing gpio_free() in case the modem platform device registration fails. Thanks to Tony Lindgren who suggested this approach instead of shifting up the gpio-generic driver initialization. In addition, defer registration of the Amstrad Delta ASoC and serio devices, done from their device driver files, until late_initcall time, as those drivers will depend on their GPIO pins already requested from the board late_init() function until updated to register their GPIO pins themselves.

If the original submission (or allocation) of the URBs for a SCSI command fails, the UAS driver sticks the command structure in a workqueue and schedules uas_do_work() to run. That function removes the entire queue before walking across it and attempting to resubmit. Unfortunately, if the second submission fails, we will leak memory (because an allocated URB was not submitted) and possibly leave the SCSI command partially enqueued on some of the stream rings. Fix this by checking whether the second submission failed and re-queueing the command to the UAS workqueue and scheduling it.

UAS can work with either USB 3.0 devices that support bulk streams, or USB 2.0 devices that do not support bulk streams. When we're working with a non-streams device, we need to be able to uniquely identify a SCSI command with a tag in the IU. Devices will barf and abort all queued commands if they find a duplicate tag. uas_queuecommand_lck() sets cmdinfo->stream to zero if the device doesn't support streams, which is later passed into uas_alloc_cmd_urb() as the variable stream. This means the UAS driver was setting the tag in all commands to zero for non-stream devices. So the UAS driver won't currently work with USB 2.0 devices. Use the SCSI command tag instead of the stream ID for the command IU tag. We have to add one to the SCSI command tag because SCSI tags are zero-based, but stream IDs are one-based, and the command tag must match the stream ID that we're queueing the data IUs for. Untagged SCSI commands use stream ID 1.

This patch uses scsi_host_find_tag() to obtain the correct command which is associated with the tag. The following changes are required: - don't use sdev->current_cmnd anymore Since we can have devices which don't support command queueing we must ensure that we can tell the two commands apart. Even if a device supports comand queuing we send the INQUIRY command "untagged" for LUN1 while we can send a tagged command to LUN0 at the same time. devinfo->cmnd is used for stashing the one "untagged" command. - tag number is altered. If stream support is used then the tag number must match the stream number. Therefore we can't use tag 0 and must start at tag 1. In case we have untagged commands (at least the first command) we must be able to distinguish between command tag 0 (which becomes 1) and untagged command (which becomes curently also 1). The following tag numbers are used: 0: never 1: for untagged commands (devinfo->cmnd) 2+: tagged commands.

A read/write looks the following way on a stream-less connection: - send cmd tag X, queue status - receive status, oh it is a read for tag X. queue status & read - receive read - receive status, oh I'm done for tag X. Cool call complete and free status urb. This block repeats itself 1:1 for further commands and looks great so far. Lets take a look now what happens if we do allow multiple commands: - send cmd tag X, queue statusX (belongs to the command with the X tag) - send cmd tag Y, queue statusY (belongs to the command with the Y tag) - receive statusX, oh it is a read for tag X. queue statusX & a read - receive read - receive statusY, oh I'm done for tag X. Cool call complete and free statusY. - receive statusX, oh it is a read for tag Y. queue statusY & before we queue the read the the following message can be observed: |sd 0:0:0:0: [sda] sense urb submission failure followed by a second attempt with the same result. In order to address this problem we will use only one status URB for each scsi host in case we don't have stream support (as suggested by Matthew). This URB is requeued until the device removed. Nothing changes on stream based endpoints.

Even more, some custom ams-delta only drivers can perhaps be dropped from the tree after converting selected ams-delta platform devices to follow generic GPIO based device models. The latch_gpios[] table is initially filled with all latch1 and latch2 GPIO pins in order to register and initialize them from the board file until those are handled by respective existing device drivers (leds, nand, lcd, serio, asoc, serial). That table will get almost empty after the transision process is completed, holding only pins not used by any drivers / connected to unused devices, in order to initialize them from the board file for power saving purposes. The new ams_delta_latch_write() function is a unified replacement for those removed ams_delta_latch[12]_write(), and serves as a temporary wrapper over gpio_set_value(), providing the old API for those not yet updated device drivers, and will be removed after all custom drivers are converted or replaced.

While requesting and initializing GPIO pins used, also take care of one extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs to the device and affects its functioning. Once done, move the driver initialization back to the device_initcall level, reverting the temporary chane introduced with patch 1/7 "ARM: OMAP1: ams-delta: register latch dependent devices later". That change is no longer required once the driver takes care of registering used GPIO pins, and it's better to initialize the device before others using the latch2 based GPIO pins, otherwise a garbage is reported on boot, perhaps due to random data already captured by the FIQ handler while the keyboard related latch bits are written with random values during initialization of those other latch2 dependent devices.

The lone user of memory_failure() will soon need to pass flags too. Add flags argument to the callsite in mce.c. Delete the old memory_failure() function, and then rename __memory_failure() without the leading "__". Provide clearer message when action optional memory errors are ignored.

The xHCI hub port code gets passed a zero-based port number by the USB core. It then adds one to in order to find a device slot by port number and device speed by calling xhci_find_slot_id_by_port. That function clearly states it requires a one-based port number. The xHCI port status change event handler was using a zero-based port number that it got from find_faked_portnum_from_hw_portnum, not a one-based port number. This lead to the doorbells never being rung for a device after a resume, or worse, a different device with the same speed having its doorbell rung (which could lead to bad power management in the xHCI host controller). This patch should be backported to kernels as old as 2.6.39.

Consequently, keeping all W[80] array on stack is unnecessary, only 16 values are really needed. Using W[16] instead of W[80] greatly reduces stack usage (~750 bytes to ~340 bytes on x86_64). Line by line explanation: * BLEND_OP array is "circular" now, all indexes have to be modulo 16. Round number is positive, so remainder operation should be without surprises. * initial full message scheduling is trimmed to first 16 values which come from data block, the rest is calculated before it's needed. * original loop body is unrolled version of new SHA512_0_15 and SHA512_16_79 macros, unrolling was done to not do explicit variable renaming.

There is no standard ror64, so create it. The difference is shift value being "unsigned int" instead of uint64_t (for which there is no reason). gcc starts to emit native ROR instructions which it doesn't do for some reason currently. This should make the code faster. Patch survives in-tree crypto test and ping flood with hmac(sha512) on.

To avoid underflow in the allocator loop, it simply raised the lower boundary to the requested size under the assumption that requested size would be far smaller than available memblocks. This causes early page table allocation failure under certain configurations in Xen. Fix it by checking for underflow directly instead of bumping up lower bound.

To address this, save local socket ->getname() output during iscsi login setup, and makes iscsit_build_sendtargets_response() return these TargetAddress keys when INADDR_ANY or IN6ADDR_ANY_INIT portals are in use.

But the hangcheck and error_capture code need to access registers without grabbing this mutex because we hold it while waiting for the gpu. So a new lock is required. Because currently the error_state capture is called from the error irq handler and the hangcheck code runs from a timer, it needs to be an irqsafe spinlock (note that the registers used by the irq handler (neglecting the error handling part) only uses registers that don't need the forcewake dance). We could tune this down to a normal spinlock when we rework the error_state capture and hangcheck code to run from a workqueue. But we don't have any read in a fastpath that needs forcewake, so I've decided to not care much about overhead. This prevents tests/gem_hangcheck_forcewake from i-g-t from killing my snb on recent kernels - something must have slightly changed the timings. On previous kernels it only trigger a WARN about the broken locking. v2: Drop the previous patch for the register writes. v3: Improve the commit message per Chris Wilson's suggestions.

Only the blt&bsd ring on ivb seem to be massively affected by this, but for paranoia do this dance also on the render ring and on snb (i.e. all gpus with forcewake). Tested with Eric's glCopyPixels loop which without this patch scores a missed irq every few seconds. This patch needs my forcewake rework to use a spinlock instead of dev->struct_mutex. After crawling through docs a lot I've found the following nugget: Internal doc "SNB GT PM Programming Guide", Section 4.3.1: "GT does not generate interrupts while in RC6 (by design)" So it looks like rc6 and irq generation are indeed related. v2: Improve the comment per Eugeni Dodonov's suggestion. v3: Add the documentation snipped. Also restrict the w/a to ivb only for -fixes, as suggested by Keith Packard.

We remove it and use a generic approach instead. A new ios_handler is added, the purpose of which e.g. can be to control GPIO pins to a levelshifter. Previously the vdd_handler was also used for making additional changes to the power register bits. This option is superfluous and is therefore removed.

This is needed because: When a CPU gets hotplugged, it's totally uninitialized and offline. cpuinfo_x86 struct (cpu_data(cpu)) is mostly zero (CPU feature flags, model, family,..). When a CPU gets hotplugged, struct processor is alloc'd, some sysfs files are set up but acpi_processor_add() must not try to access a MSR on this CPU or try to read out CPU feature,family, etc. This must be done in acpi_processor_start(). The next patch will delay the call of acpi_processor_start() for physically hotpluggedcores, to the time when they are onlined the first time. There it is safe then to access cpu_data(cpu) cpuinfo_x86 struct or access MSRs which is needed to set up cpuidle, throttling and other features.

ALSA allows us to set a msbits constraint which tells userspace about this in case it finds it useful (for example, in order to avoid wasting effort dithering bits that will be ignored when raising the sample size of data) so provide a mechanism for drivers to specify the number of bits that are actually significant on a DAI and add the appropriate constraints along with all the others. This is done slightly awkwardly as the constraint is specified per sample size - we loop over every possible sample size, including ones that the device doesn't support and including ones that have fewer bits than are actually used, but this is harmless as the upper layers do the right thing in these cases.

Subject: [PATCH 0282/7995] ARM: at91: Fix at91sam9g45 and at91cap9 reset As on the other sam9 we need to cleanly shutdown the DDRAM before rebooting. On those SoC the SDRAM/DDRAM controller is different. So, the assembly code ends up being not cleanly combined with previous at91sam9_alt_restart function.

This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register. --- arch/arm/mach-sa1100/assabet.c | 1 - arch/arm/mach-sa1100/cerf.c | 1 - arch/arm/mach-sa1100/collie.c | 8 +---- arch/arm/mach-sa1100/include/mach/mcp.h | 2 -- arch/arm/mach-sa1100/lart.c | 1 - arch/arm/mach-sa1100/shannon.c | 1 - arch/arm/mach-sa1100/simpad.c | 8 +---- drivers/mfd/mcp-core.c | 44 ++--------------------- drivers/mfd/mcp-sa11x0.c | 7 ++-- drivers/mfd/ucb1x00-core.c | 48 ++++++------------------- drivers/mfd/ucb1x00-ts.c | 2 +- include/linux/mfd/mcp.h | 7 ++-- include/linux/mfd/ucb1x00.h | 5 +-- include/linux/mod_devicetable.h | 11 ------ scripts/mod/file2alias.c | 10 ------ 15 files changed, 21 insertions(+), 135 deletions(-) diff --git a/arch/arm/mach-sa1100/assabet.c b/arch/arm/mach-sa1100/assabet.c index d8aa1c28353b..0c4b76ab4d8e 100644 --- a/arch/arm/mach-sa1100/assabet.c +++ b/arch/arm/mach-sa1100/assabet.c @@ -202,7 +202,6 @@ static struct irda_platform_data assabet_irda_data = { static struct mcp_plat_data assabet_mcp_data = { .mccr0 = MCCR0_ADM, .sclk_rate = 11981000, - .codec = "ucb1x00", };

This timeout happens because clk_set_rate will result in writing to the DIV bits of register HW_CLKCTRL_SAIF0 with the saif clock gated (CLKGATE bit set to one). MX28 Reference states the following about CLKGATE: "The DIV field can change ONLY when this clock gate bit field is low." So call clk_prepare_enable prior to clk_set_rate to fix this problem.

The forceful re-enablement of IRQs after pm_idle has returned can go. The warning certainly doesn't trigger for existing users. To get rid of the pm_idle calling convention oddity, let's introduce arm_pm_idle() allowing for the local_irq_enable() to be factored out from SOC specific implementations. The default pm_idle function becomes a wrapper for arm_pm_idle and it takes care of enabling IRQs closer to where they are initially disabled. And finally move the comment explaining the reason for that turning off of IRQs to a more proper location.

In the cited case, %ebx and %ecx are inputs only (don't get changed by either of the two low level implementations). This was also the case elsewhere. Further in many cases early-clobber indicators were missing. Finally, the previous implementation rolled a custom alternative instruction macro from scratch, rather than using alternative_call() (which was introduced with the commit that the description of the change in question actually refers to). Adjusting has the benefit of not hiding referenced symbols from the compiler, which however requires them to be declared not just in the exporting source file (which, as a desirable side effect, in turn allows that exporting file to become a real 5-line stub). This patch does not eliminate the overly restrictive memory clobbers, however: Doing so would occasionally make the compiler set up a second register for accessing the memory object (to satisfy the added "m" constraint), and it's not clear which of the two non-optimal alternatives is better. v2: Re-do the declaration and exporting of the internal symbols.

In the "add_unless" implementation, swapping the use of %ecx and %esi for passing arguments allows %esi to become an input only (i.e. permitting the register to be re-used to address the same object without reload). In "{add,sub}_return", doing the initial read64 through the passed in %ecx decreases a register dependency. In "inc_not_zero", a branch can be eliminated by or-ing together the two halves of the current (64-bit) value, and code size can be further reduced by adjusting the arithmetic slightly. v2: Undo the folding of "xchg" and "set".

This patch implements 64-bit read and write routines for APEI usage. This patch re-factors similar functionality introduced in commit 04c25997c97, bringing it into the ACPI subsystem in preparation for removing ./drivers/acpi/atomicio.[ch]. In the implementation I have replicated acpi_os_read_memory() and acpi_os_write_memory(), creating 64-bit versions for APEI to utilize, as opposed to something more elegant. My thinking is that we should attempt to see if we can get ACPI's CA/OSL changed so that the existing acpi_read() and acpi_write() interfaces are natively 64-bit capable and then subsequently remove the replication.

This means that if the hardware reports an error (especially one which might not stall transfer) we might miss it. Take a first pass at dealing with such errors by enabling the interrupt if we can and logging the errors if they happen. Ideally we'd report the error via the affected transfer but since we're in master mode it's very difficult to trigger errors at present and this code is much simpler.

There are two reasons for that: 1) The firmware used there didn't work for a few devices I tested here (Terratec H5, H6 and H7); 2) At least Terratec H7 doesn't seem to require a firmware for it to work. After this change, if firmware is not specified, the driver will use a rom-based firmware (this seems to be the case for Terratec H7, although I need to better check the USB dumps to be sure about that). In any case, the firmware seems to be optional, as the DRX-K driver don't return the firmware load error.

This occurs because two things happen: 1. When we suspended, we were woken up, and executed the loop. Finding that the touchscreen was not pressed, we prepare to schedule for a maximum timeout, before being stopped in try_to_freeze(). 2. an irq occurs, we disable the irq, and mark it as disabled, and wake the thread. This wake occurs while the thread is still within __refrigerator() 3. The thread is unfrozen, and __refrigerator() sets the threads state back to INTERRUPTIBLE. We then drop into schedule_timeout() with an infinite timeout and the IRQ disabled. This prevents any further screen touches activating the thread. Fix this by using kthread_freezable_should_stop() which handles the freezing issues for us outside of the hotspot where the task state matters. Include a flag to ignore the touchscreen until it is released to avoid sending unintended data to the application.

Since Cortex-A8 and Cortex-A15 have 64-byte cachelines (and it is likely that there will be future ARMv7 implementations with the same line size) then it makes sense to assume that CPU_V7 implies a 64-byte L1 cacheline size. For CPUs with smaller caches, this will result in some harmless padding but will help with single zImage work and avoid hitting subtle bugs with misaligned data structures.

This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

Support such updates by allowing drivers to register update sets with the core. These updates will be written to the device immediately and will also be rewritten when the cache is synced. The assumption is that the reason for resyncing the cache will always be that the device has been powered off. If this turns out to not be the case then a separate operation can be provided. Currently the implementation only allows a single set of updates to be specified for a device, this could be extended in future.

This however prints an annoying warning for kmod tool, that is currently replacing module-init-tools. Rather than putting another check for kmod's version, just remove it since users of 2.4.x kernel are unlikely to upgrade to 3.x, and if they do, let depmod fail in that case because they should know what they are doing.

(There seems to have been a race between him fixing that and the extra clause going in a little later). I don't actually know the dmatest code/structures, nor do I own any hardware to test it on (assuming it needs a DMA engine); but this patch builds, the existing code is almost certainly wrong and the fix is the same as the corresponding lines above it.

What we are trying to so here is map a couple of data structures that the EINJ table points to. Perhaps acpi_os_map_memory() is a better tool for this? Most importantly it works, but as a side benefit it maps the structures into kernel virtual space so we can access them with normal C memory dereferences, so instead of using: writel(param1, &v5param->apicid);

I don't think that it is might be wrong to initialize the stream capability even at HS speed. The gadget may not use this descriptor at HS speed so it should not cause any damage.

The transfer side also lacks matching of streams. This patch changes this and implements stream allocation / de-allocation support and proper urb <=> req matching. The UDC side exposes a limit of 16 streams. DWC3, the only USB3 UDC has no limitations in this regard except that it _needs_ to know that streams will be used at the ep_enable time. At the host side, there is no real limit either: XHCI can allocate any number of streams as long as it does not run out of memory. The UAS gadget currently requests 16 streams and the UAS host side fallbacks from the requested 256 down to 16 which is fine. From the UASP point of view (the only specified user), the number of used streams does not really matter. The only limitation is that the host may not use a higher stream than the gadget requested and can deal with. The dummy stream support has been modelled after current UAS + XHCI + DWC3 + UASP usage which helps me testing: - the device announces that each ep supports 16 streams (even it could more than that). - the device side looks into Companion descriptor at ep_enable time and enables them according to it. - the host side tries to enable the requested number of streams but the upper limit is the Comanion descriptor. None (zero streams) is an error condition, less is okay.

But we've already done that just a few lines above. That's a use-after-free bug. This patch restructures the code so that we always call release_firmware(fw) before leaving the function, but only ever call it once. This means that we have to initialize 'fw' to NULL since some paths may now end up calling it without having called request_firmware(), but since request_firmware() deals gracefully with NULL pointers, we are fine if we just NULL initialize it.

When a spin lock is contended and xl->spinners is modified the two bytes immediately after the spin lock would be corrupted. This is a regression caused by 84eb950db13ca40a0572ce9957e14723500943d6 (x86, ticketlock: Clean up types and accessors) which reduced the size of arch_spinlock_t. Fix this by making xl->spinners a u8 if NR_CPUS < 256. A BUILD_BUG_ON() is also added to check the sizes of the two structures are compatible. In many cases this was not noticable as there would often be padding bytes after the lock (e.g., if any of CONFIG_GENERIC_LOCKBREAK, CONFIG_DEBUG_SPINLOCK, or CONFIG_DEBUG_LOCK_ALLOC were enabled). The bnx2 driver is affected. In struct bnx2, phy_lock and indirect_lock may have no padding after them. Contention on phy_lock would corrupt indirect_lock making it appear locked and the driver would deadlock.

The current cp210x.ko driver in kernel version 3.2.0 only implements the GET/SET_BAUDDIV command. This patch implements the two new codes for the GET/SET_BAUDRATE commands. Then there is a change in the way that the baudrate is assigned or retrieved. This is done according to the CP210x USB specification in AN571. This document can be found here: http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart Sections 5.3/5.4 describe the USB packets for the old baudrate method. Sections 5.5/5.6 describe the USB packets for the new method. This patch also implements the new request scheme, and eliminates the unnecessary baudrate calculations since it uses the "actual baudrate" method. This patch solves the problem reported for the CP2104 in bug 42586, and also keeps support for all other devices (CP2101/2/3). This patchfile is also attached to the bug report on bugzilla.kernel.org. This patch has been developed and test on the 3.2.0 mainline kernel version under Ubuntu 10.11.

Biederman" Date: Fri, 13 Jan 2012 21:32:59 -0800 Subject: [PATCH 0544/7995] sysfs: Complain bitterly about attempts to remove files from nonexistent directories. Recently an OOPS was observed from the usb serial io_ti driver when it tried to remove sysfs directories. Upon investigation it turns out this driver was always buggy and that a recent sysfs change had stopped guarding itself against removing attributes from sysfs directories that had already been removed. :( Historically we have been silent about attempting to files from nonexistent sysfs directories and have politely returned error codes. That has resulted in people writing broken code that ignores the error codes. Issue a kernel WARNING and a stack backtrace to make it clear in no uncertain terms that abusing sysfs is not ok, and the callers need to fix their code. This change transforms the io_ti OOPS into a more comprehensible error message and stack backtrace. Signed-off-by: Eric W.

Because we now only use a single rbtree this reduces the size of sysfs_dirent by 2 pointers. Because we have fewer cases to deal with the code is now simpler. For now I use the simple hash that the dcache uses as that is easy to use and seems simple enough. In addition to makeing the code simpler using a hash for the file position in readdir brings sysfs in line with other filesystems that have non-trivial directory structures. Signed-off-by: Eric W.

Biederman" Date: Sun, 18 Dec 2011 20:09:31 -0800 Subject: [PATCH 0556/7995] sysfs: Kill nlink counting. Tracking the number of subdirectories requires an extra field that increases the size of sysfs_dirent. nlinks are not particularly interesting for sysfs and the nlink counts are wrong when network namespaces are involved so stop counting them, and always return nlink == 1. Userspace already knows that directories with nlink == 1 have an nlink count they can't use to count subdirectories. This reduces the size of sysfs_dirent by 8 bytes on 64bit platforms.

It splits the query string on [;\n], and calls ddebug_exec_query() on each. All queries are processed independent of errors, allowing a query to fail, for example when a module is not installed. Empty lines and comments are skipped. Errors are counted, and the last error seen (negative) or the number of callsites found (0 or positive) is returned. Return code checks are altered accordingly. With this, multiple queries can be given in ddebug_query, allowing more selective enabling of callsites. As a side effect, a set of commands can be batched in: cat cmd-file > $DBGMT/dynamic_debug/control We dont want a ddebug_query syntax error to kill the dynamic debug facility, so dynamic_debug_init() zeros ddebug_exec_queries()'s return code after logging the appropriate message, so that ddebug tables are preserved and $DBGMT/dynamic_debug/control file is created. This would be appropriate even without accepting multiple queries. This patch also alters ddebug_change() to return number of callsites matched (which typically is the same as number of callsites changed). ddebug_exec_query() also returns the number found, or a negative value if theres a parse error on the query. Splitting on [;\n] prevents their use in format-specs, but selecting callsites on punctuation is brittle anyway, meaningful and selective substrings are more typical. Note: splitting queries on ';' before handling trailing #comments means that a ';' also terminates a comment, and text after the ';' is treated as another query. This trailing query will almost certainly result in a parse error and thus have no effect other than the error message.

The serial eventually freezes while being used. It's completely unpredictable and sometimes needs a heap of traffic to happen first. To reproduce this, yast installation was used as it turned out to be pretty reliable in reproducing. Especially during installation process where one doesn't have an SSH daemon running. And no monitor as the HW is completely headless. So this was fun to find. Given the machine doesn't boot on vanilla before 2.6.36 final. (And the commits above are older.) Unless there is some bad race in the code, the hardware seems to be pretty broken. Otherwise pure MSR read should not cause such a bug, or? So to prevent the bug, revert to the old behavior. I.e. read modem status only if we really have to -- for non-CLOCAL set serials. Non-CLOCAL works on this hardware OK, I tried. See? I don't. And document that shit.

Fix this by renaming (through the pre-processor) the conflicting symbol. On my Westmere system, the glibc variant turns out to require about 4% less instructions, but 15% more cycles for the default 1Mb block size measured.

This patch restores sysctl kernel.pty.max as global limit (4096 by default), adds pty reseve for main devpts (mounted without "newinstance" argument), and new sysctl to tune it: kernel.pty.reserve (1024 by default) Also it adds devpts mount option "max=%d" to limit pty count for each devpts instance independently. (by default NR_UNIX98_PTY_MAX == 2^20) Thus devpts instances in containers cannot eat up all available pty even if we didn't set any limits, while with "max" argument we can adjust limits more precisely. Plus, now open("/dev/ptmx") return -ENOSPC in case lack of pty indexes, this is more informative than -EIO.

This appears to be a silicon bug. This means that if the MPU powerdomain is in a low-power state, the MPU will not be awakened to refill the FIFO until the next interrupt from another device. The best solution, at least for the short term, would be for the OMAP serial driver to call a OMAP subarchitecture function to prevent the MPU powerdomain from entering a low power state while the FIFO has data to transmit. However, we no longer have a clean way to do this, since patches that add platform_data function pointers have been deprecated by the OMAP maintainer. So we attempt to work around this as well. The workarounds depend on the setting of CONFIG_CPU_IDLE. When CONFIG_CPU_IDLE=n, the driver will now only transmit one byte at a time. This causes the transmit FIFO threshold interrupt to stay active until there is no more data to be sent. Thus, the MPU powerdomain stays on during transmits. Aside from that energy consumption penalty, each transmitted byte results in a huge number of UART interrupts -- about five per byte. This wastes CPU time and is quite inefficient, but is probably the most expedient workaround in this case. When CONFIG_CPU_IDLE=y, there is a slightly more direct workaround: the PM QoS constraint can be abused to keep the MPU powerdomain on. This results in a normal number of interrupts, but, similar to the above workaround, wastes power by preventing the MPU from entering WFI. Future patches are planned for the 3.4 merge window to implement more efficient, but also more disruptive, workarounds to these problems. DMA operation is unaffected by this patch.

This prevents _GNU_SOURCE in util.h from enabling the declaration of getline(), from now second inclusion of stdio.h, and the build is broken. There is another breakage in util/evsel.c caused by include ordering, but I didn't fully track down the commit that caused it. The root cause of all this is an inconsistent definition of _GNU_SOURCE, so I move the definition into the Makefile so that it is passed to all invocations of the compiler and used uniformly for all system header files. All other #define and #undef of _GNU_SOURCE are removed as they cause conflicts with the definition passed to the compiler. All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64 and _GNU_SOURCE) are needed by the python glue code too, so they are moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS are removed.

The patch also adjusts all the callers of driver_find() to remove the now unnecessary calls to put_driver(). In addition, the patch adds a warning to driver_find(): Callers must make sure the driver they are searching for does not get unloaded while they are using it. This has always been the case; driver_find() has never prevented a driver from being unregistered or unloaded. Hence the patch will not introduce any new bugs. The existing callers all seem to be okay in this respect, however I don't understand the video drivers well enough to be certain about them.

Since these additions are done by writing to the drivers' sysfs attribute files, and the attributes are removed when the drivers are unregistered, there is no reason to take an extra reference to the drivers. The one exception is the pci-stub driver, which calls pci_add_dynid() as part of its registration. But again, there's no reason to take an extra reference here, because the driver can't be unloaded while it is being registered.

But this is avoidable since it is the device_set_wakeup_enable() and then subsequence disable which causes the delay. We might as well just make the device wakeup capable but not actually enable it for wakeup until needed. Effectively the current code does this: device_set_wakeup_capable(dev, 1); device_set_wakeup_enable(dev, 1); device_set_wakeup_enable(dev, 0); We can just drop the last two lines. Before this change my boot log says: [ 0.227062] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled [ 0.702928] serial8250.0: ttyS0 at MMIO 0x70006040 (irq = 69) is a Tegra after: [ 0.227264] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled [ 0.227983] serial8250.0: ttyS0 at MMIO 0x70006040 (irq = 69) is a Tegra for saving of 450ms.

Make __register_sysctl_table the core sysctl registration operation and make it take a char * string as path. Now that binary paths have been banished into the real of backwards compatibility in kernel/binary_sysctl.c where they can be safely ignored there is no longer a need to use struct ctl_path to represent path names when registering ctl_tables. Start the transition to using normal char * strings to represent pathnames when registering sysctl tables. Normal strings are easier to deal with both in the internal sysctl implementation and for programmers registering sysctl tables. __register_sysctl_paths is turned into a backwards compatibility wrapper that converts a ctl_path array into a normal char * string.

Biederman" Date: Sun, 22 Jan 2012 18:22:05 -0800 Subject: [PATCH 0654/7995] sysctl: register only tables of sysctl files Split the registration of a complex ctl_table array which may have arbitrary numbers of directories (->child != NULL) and tables of files into a series of simpler registrations that only register tables of files. Graphically: register('dir', { + file-a + file-b + subdir1 + file-c + subdir2 + file-d + file-e }) is transformed into: wrapper->subheaders[0] = register('dir', {file1-a, file1-b}) wrapper->subheaders[1] = register('dir/subdir1', {file-c}) wrapper->subheaders[2] = register('dir/subdir2', {file-d, file-e}) return wrapper This guarantees that __register_sysctl_table will only see a simple ctl_table array with all entries having (->child == NULL). Care was taken to pass the original simple ctl_table arrays to __register_sysctl_table whenever possible. This change is derived from a similar patch written by Lucrian Grijincu.

Biederman" Date: Sat, 21 Jan 2012 13:34:05 -0800 Subject: [PATCH 0655/7995] sysctl: Improve the sysctl sanity checks - Stop validating subdirectories now that we only register leaf tables - Cleanup and improve the duplicate filename check. * Run the duplicate filename check under the sysctl_lock to guarantee we never add duplicate names. * Reduce the duplicate filename check to nearly O(M*N) where M is the number of entries in tthe table we are registering and N is the number of entries in the directory before we got there. - Move the duplicate filename check into it's own function and call it directtly from __register_sysctl_table - Kill the config option as the sanity checks are now cheap enough the config option is unnecessary. The original reason for the config option was because we had a huge table used to verify the proc filename to binary sysctl mapping. That table has now evolved into the binary_sysctl translation layer and is no longer part of the sysctl_check code. - Tighten up the permission checks. Guarnateeing that files only have read or write permissions. - Removed redudant check for parents having a procname as now everything has a procname. - Generalize the backtrace logic so that we print a backtrace from any failure of __register_sysctl_table that was not caused by a memmory allocation failure. The backtrace allows us to track down who erroneously registered a sysctl table.

Biederman" Date: Thu, 29 Dec 2011 08:24:29 -0800 Subject: [PATCH 0665/7995] sysctl: Stop requiring explicit management of sysctl directories Simplify the code and the sysctl semantics by autogenerating sysctl directories when a sysctl table is registered that needs the directories and autodeleting the directories when there are no more sysctl tables registered that need them. Autogenerating directories keeps sysctl tables from depending on each other, removing all of the arcane register/unregister ordering constraints and makes it impossible to get the order wrong when reigsering and unregistering sysctl tables. Autogenerating directories yields one unique entity that dentries can point to, retaining the current effective use of the dcache. Add struct ctl_dir as the type of these new autogenerated directories. The attached_by and attached_to fields in ctl_table_header are removed as they are no longer needed. The child field in ctl_table is no longer needed by the core of the sysctl code. ctl_table.child can be removed once all of the existing users have been updated.

Biederman" Date: Sat, 7 Jan 2012 23:24:30 -0800 Subject: [PATCH 0667/7995] sysctl: Replace root_list with links between sysctl_table_sets. Piecing together directories by looking first in one directory tree, than in another directory tree and finally in a third directory tree makes it hard to verify that some directory entries are not multiply defined and makes it hard to create efficient implementations the sysctl filesystem. Replace the sysctl wide list of roots with autogenerated links from the core sysctl directory tree to the other sysctl directory trees. This simplifies sysctl directory reading and lookups as now only entries in a single sysctl directory tree need to be considered. Benchmark before: make-dummies 0 999 -> 0.44s rmmod dummy -> 0.065s make-dummies 0 9999 -> 1m36s rmmod dummy -> 0.4s Benchmark after: make-dummies 0 999 -> 0.63s rmmod dummy -> 0.12s make-dummies 0 9999 -> 2m35s rmmod dummy -> 18s The slowdown is caused by the lookups used in insert_headers and put_links to see if we need to add links or remove links.

Biederman" Date: Wed, 18 Jan 2012 22:57:15 -0800 Subject: [PATCH 0669/7995] sysctl: Move sysctl_check_dups into insert_header Simplify the callers of insert_header by removing explicit calls to check for duplicates and instead have insert_header do the work. This makes the code slightly more maintainable by enabling changes to data structures where the insertion of new entries without duplicate suppression is not possible. There is not always a convenient path string where insert_header is called so modify sysctl_check_dups to use sysctl_print_dir when printing the full path when a duplicate is discovered.

Several of those tunables are per network device. In several instances people are running with 1000+ network devices in there network stacks, which makes the simple per directory linked list in sysctl a scaling bottleneck. Replace O(N^2) sysctl insertion and lookup times with O(NlogN) by using an rbtree to index the sysctl directories.

I have commented out the code that adds and removes files under /proc/sys/net/dev_snmp6 and taken measurments of creating and destroying 100,000 dummies to verify the sysctl continues to scale.

This is caused by the way the mappings are described on this platform (define replaced by hex values for clarity): { /* GIC CPU interface mapping */ .virtual = IO_ADDRESS(0x1F000100), .pfn = __phys_to_pfn(0x1F000100), .length = SZ_4K, .type = MT_DEVICE, }, { /* GIC distributor mapping */ .virtual = IO_ADDRESS(0x1F001000), .pfn = __phys_to_pfn(0x1F001000), .length = SZ_4K, .type = MT_DEVICE, } The first mapping ends up reserving two pages, and clashes with the second one, which triggers a BUG_ON in vm_area_add_early(). In order to solve this problem, treat the MPCore private memory region (containing the SCU, the GIC and the TWD) as a single region, as described in the TRM: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html The EB11MP is converted the same way, even if it manages to avoid the problem. Tested on both PB11MP and EB11MP.

This is because while the addresses in the mcount records do not have the zero bit set, the IP reported by the mcount call does have it set (because it is copied from the LR). This mismatch causes the ops filtering in ftrace_ops_list_func() to not call the relevant tracers. Fix this by clearing the zero bit before adjusting the LR for the mcount instruction size. Also, combine the mov+sub into a single sub instruction.

With the pending NO_IRQ cleanup, this will lead to a warning at boot time, since -1 is obviously broken. This patch updates the interrupt used for GPIO0 to match that specified by the TRM. Unfortunately, it's not clear how to trigger this interrupt so we trust that the documentation is correct.

This is done mainly in four functions: mgr_enable/disable and ovl_enable/disable. These are the functions where overlays are taken into and out of active use. The process to enable and disable fifo-merge is not simple. We need to do it in steps, waiting in between for certain settings to be taken into use, and continuing after that. The reason for this is that fifo-merge is a common thing for all managers/overlays, and its use must be synchronized. As an example, when we disable an overlay, we first set the overlay as disabled, then wait until the overlay is actually disabled in the HW, and only after that we may re-configure the fifos, possibly taking fifo-merge into use.

This should greatly increase the time between pixel data fetches from SDRAM, as the usable fifo size is much larger.

The above commit moves the call to move_notify() to after move() has been done, which means that now, sometimes, new_mem isn't the new node at all, bo->mem is, and new_mem points at a stale, possibly-just-been-killed-by-move node. This is clearly not a good situation. This patch reverts this change, and replaces it with a cleanup in the move() failure path instead. The second issue is that the call to move_notify() from cleanup_memtype_use() causes the TTM ghost objects to get passed into the driver. This is clearly bad as the driver knows nothing about these "fake" TTM BOs, and ends up accessing uninitialised memory. I worked around this in nouveau's move_notify() hook by ensuring the BO destructor was nouveau's. I don't particularly like this solution, and would rather TTM never pass the driver these objects. However, I don't clearly understand the reason why we're calling move_notify() here anyway and am happy to work around the problem in nouveau instead of breaking the behaviour expected by other drivers.

It grabs a page, zeroes out the appropriate portions, and then encrypts the page before writing it to the lower filesystem. It was unkillable and due to the lack of sparse file support could result in tying up a large portion of system resources, while encrypting pages of zeros, with no way for the truncate operation to be stopped from userspace. This patch adds the ability for ecryptfs_write() to detect a pending fatal signal and return as gracefully as possible. The intent is to leave the lower file in a useable state, while still allowing a user to break out of the encryption loop. If a pending fatal signal is detected, the eCryptfs inode size is updated to reflect the modified inode size and then -EINTR is returned.

It allowed the lower filesystem to make the call in its ->setattr() function. Then, eCryptfs would copy the appropriate inode attributes from the lower inode to the eCryptfs inode. This patch changes that and actually calls inode_change_ok() on the eCryptfs inode, fairly early in ecryptfs_setattr(). Ideally, the call would happen earlier in ecryptfs_setattr(), but there are some possible inode initialization steps that must happen first. Since the call was already being made on the lower inode, the change in functionality should be minimal, except for the case of a file extending truncate call. In that case, inode_newsize_ok() was never being called on the eCryptfs inode. Rather than inode_newsize_ok() catching maximum file size errors early on, eCryptfs would encrypt zeroed pages and write them to the lower filesystem until the lower filesystem's write path caught the error in generic_write_checks(). This patch introduces a new function, called ecryptfs_inode_newsize_ok(), which checks if the new lower file size is within the appropriate limits when the truncate operation will be growing the lower file. In summary this change prevents eCryptfs truncate operations (and the resulting page encryptions), which would exceed the lower filesystem limits or FSIZE rlimits, from ever starting.

Currently this is broken as dss_core is listed in chip/revision specific hwmod lists while other DSS hwmods are listed in common list which is registered first. This patch moves DSS hwmods (except for dss_core) to the separate list which is registered last to ensure that dss_core is already registered. This solves the problem with BUG() in L3 interrupt handler on boards with DSS enabled in bootloader. The long-term fix to this is to ensure modules are set up in dependency order in the hwmod core code.

The Huawei E392/E398 are examples of such devices. These typically cannot be fully configured using AT commands over a serial interface. It is necessary to speak the proprietary Qualcomm MSM Interface (QMI) protocol to the device to enable the ethernet proxy functionality. The devices embed the QMI protocol in CDC on the control interface, using standard CDC commands and notifications. The do not otherwise use CDC commands for the ethernet function. This driver does therefore not need access to any other aspects of the control interface than the descriptors attached to it. Another driver, cdc-wdm, will provide userspace access to the QMI protocol independently of this driver. To facilitate this, this driver avoids binding to the control interface, and uses only the associated data interface after parsing the common CDC functional descriptors on the control interface. You will want both the cdc-wdm and option drivers as companions to this driver, to have full access to all interfaces and protocols exported by the device.

Chris Wilson tracked down the issue to recursive calls to unmap. This happens because we try to optimize waiting on requests by calling retire requests after the wait, which may drop the last reference on an object and end up freeing the object (and then unmap the object from the gtt). After the last patch we can now choose to defer processing the retire list. Kudos to Chris Wilson for tracking this one down. This patch fixes gem_unref_active_buffers from i-g-t. It was tested by forcing do_idle_maps to true. This also fixes tests/gem_linear_blits in intel-gpu-tools.

Container files which include patches larger than 2KB cause different kinds of trouble with such old patch loaders.

The problem seems to be the fact that omapdss uses pm_runtime_put() functions when turning off the hardware, and when system suspend is in process only sync versions are allowed. Using non-sync versions normally and sync versions when suspending would need rather ugly hacks to convey the information of suspending/not-suspending to different functions. Optimally the driver wouldn't even need to care about this, and the PM layer would handle syncing when suspend is in process. This patch changes all omapdss's pm_runtime_put calls to pm_runtime_put_sync. This fixes the suspend problem, and probably the performance penalty of always using sync versions is negligible.

This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view.
