2010-04-26perf tools: Fix libdw-dev package name in error messageStefan Hajnoczi
The headers required for DWARF support are provided by the libdw-dev package in Debian-based distros. This patch corrects the elfutils-dev package name to libdw-dev in the Makefile error message when libdw.h is not found.

2010-04-24perf: Generalize perf lock's sample event reordering to the session layerFrederic Weisbecker
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.

2010-04-24perf lock: Fix state machine to recognize lock sequenceHitoshi Mitake
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>

2010-04-22USB: put claimed interfaces in the "suspended" stateAlan Stern
This patch (as1370) fixes a bug in the USB runtime power management code. 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.

2010-04-22USB: fix remote wakeup settings during system sleepAlan Stern
This patch (as1363) changes the way USB remote wakeup is handled during system sleeps. 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.

2010-04-22drm/i915: use PIPE_CONTROL instruction on Ironlake and Sandy BridgeJesse Barnes
Since 965, the hardware has supported the PIPE_CONTROL command, which provides fine grained GPU cache flushing control. On recent chipsets, this instruction is required for reliable interrupt and sequence number reporting in the driver. So add support for this instruction, including workarounds, on Ironlake and Sandy Bridge hardware. https://bugs.freedesktop.org/show_bug.cgi?id=27108 Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>

2010-04-22[S390] zcore: Fix reipl device detectionMichael Holzheu
The reipl device information is passed from the kernel to zfcpdump using a pointer in the lowcore (0xe00) that points to the reipl information Currently if that pointer is not zero, we copy the reipl information. If the pointer is not initialized and points outside the accessible memory, it can happen that the memory copy fails. In that case we currently stop the initialization of zcore which leads to a failing kernel dump. The correct behavior is to disable the reipl after dump and continue with zcore intialization.
