| | | | | | | | | | | | | | | | | | Use the new generic sample events reordering from perf trace.

* perf: Generalize perf lock's sample event reordering to the session layerFrederic Weisbecker2010-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sample events recorded by perf record are not time ordered because we have one buffer per cpu for each event (even demultiplexed per task/per cpu for task bound events). But when we read trace events we want them to be ordered by time because many state machines are involved. There are currently two ways perf tools deal with that: - use -M to multiplex every buffers (perf sched, perf kmem) But this creates a lot of contention in SMP machines on record time. - use a post-processing time reordering (perf timechart, perf lock) The reordering used by timechart is simple but doesn't scale well with huge flow of events, in terms of performance and memory use (unusable with perf lock for example). Perf lock has its own samples reordering that flushes its memory use in a regular basis and that uses a sorting based on the previous event queued (a new event to be queued is close to the previous one most of the time). This patch proposes to export perf lock's samples reordering facility to the session layer that reads the events. So if a tool wants to get ordered sample events, it needs to set its struct perf_event_ops::ordered_samples to true and that's it. This prepares tracing based perf tools to get rid of the need to use buffers multiplexing (-M) or to implement their own reordering. Also lower the flush period to 2 as it's sufficient already.

* perf lock: Fix state machine to recognize lock sequenceHitoshi Mitake2010-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous state machine of perf lock was really broken. This patch improves it a little. This patch prepares the list of state machine that represents lock sequences for each threads. These state machines can be one of these sequences: 1) acquire -> acquired -> release 2) acquire -> contended -> acquired -> release 3) acquire (w/ try) -> release 4) acquire (w/ read) -> release The case of 4) is a little special. Double acquire of read lock is allowed, so the state machine counts read lock number, and permits double acquire and release. But, things are not so simple. Something in my model is still wrong. I counted the number of lock instances with bad sequence, and ratio is like this (case of tracing whoami): bad:233, total:2279 version 2: * threads are now identified with tid, not pid * prepared SEQ_STATE_READ_ACQUIRED for read lock. * bunch of struct lock_seq_stat is now linked list * debug information enhanced (this have to be removed someday) e.g. | === output for debug=== | | bad:233, total:2279 | bad rate:0.000000 | histogram of events caused bad sequence | acquire: 165 | acquired: 0 | contended: 0 | release: 68 Signed-off-by: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jens Axboe <jens.axboe@oracle.com> Cc: Jason Baron <jbaron@redhat.com> Cc: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Cc: Ingo Molnar <mingo@elte.hu> LKML-Reference: <1271852634-9351-1-git-send-email-mitake@dcl.info.waseda.ac.jp> [rename SEQ_STATE_UNINITED to SEQ_STATE_UNINITIALIZED] Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds mappings from the register numbers from DWARF to the register names used in the PowerPC Regs and Stack Access API. This allows perf probe to be used to record variable contents on PowerPC. This requires the functionality represented by the config symbol HAVE_REGS_AND_STACK_ACCESS_API in order to function, although it will compile without it.

When a driver claims an interface, it doesn't expect to need to call usb_autopm_get_interface() or usb_autopm_put_interface() for runtime PM to work. Runtime PM can be controlled by the driver's primary interface; the additional interfaces it claims shouldn't interfere. As things stand, the claimed interfaces will prevent the device from autosuspending. To fix this problem, the patch sets interfaces to the suspended state when they are claimed. Also, although in theory this shouldn't matter, the patch changes the suspend code so that interfaces are suspended in reverse order from detection and resuming. This is how the PM core works, and we ought to use the same approach.

It won't be enabled unless an interface driver specifically needs it. Also, it won't be enabled during the FREEZE or QUIESCE phases of hibernation, when the system doesn't respond to wakeup events anyway. Finally, if the device is already runtime-suspended with remote wakeup enabled, but wakeup is supposed to be disabled for the system sleep, the device gets woken up so that it can be suspended again with the proper wakeup setting. This will fix problems people have reported with certain USB webcams that generate wakeup requests when they shouldn't, and as a result cause system suspends to fail.

This is supported by an otherwise totally misleading XXX comment. This bug mostly resulted in tiling-corrupted pixmaps because the kernel allowed too wide buffers to be tiled. Bug brought to the light by the xf86-video-intel 2.11 release because that unconditionally enabled tiling for pixmaps, relying on the kernel to check things. Tiling for the framebuffer was not affected because the ddx does some additional checks there ensure the buffer is within hw-limits. v2: Instead of computing the value that would be written into the hw fence registers and then checking the limits simply check whether the stride is above the 8kb limit. To better document the hw, add some WARN_ONs in i915_write_fence_reg like I've done for the i830 case (using the right limits).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | we used to set the DIDL in the output device detected order. But some BIOSes requires it to be initialized in the ACPI device order. e.g. the value of the first field in DIDL stands for the first ACPI video output device in ACPI namespace. Now we initialize the DIDL using the device id, i.e. _ADR return value, of each ACPI video device, if it is not 0. https://bugzilla.kernel.org/show_bug.cgi?id=15054 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>

This also correctly handles the case where the lock operation did not finish, instead of silently returning an uninitialized value.
