workqueue: rename cpu_workqueue to pool_workqueue

2013-02-14T03:29:12Z

workqueue has moved away from global_cwqs to worker_pools and with the scheduled custom worker pools, wforkqueues will be associated with pools which don't have anything to do with CPUs. The workqueue code went through significant amount of changes recently and mass renaming isn't likely to hurt much additionally. Let's replace 'cpu' with 'pool' so that it reflects the current design. * s/struct cpu_workqueue_struct/struct pool_workqueue/ * s/cpu_wq/pool_wq/ * s/cwq/pwq/ This patch is purely cosmetic.

workqueue: move global_cwq->cpu to worker_pool

2013-01-24T19:01:33Z

Move gcwq->cpu to pool->cpu. This introduces a couple places where gcwq->pools[0].cpu is used. These will soon go away as gcwq is further reduced. This is part of an effort to remove global_cwq and make worker_pool the top level abstraction, which in turn will help implementing worker pools with user-specified attributes.

workqueue: factor out worker_pool from global_cwq

2012-07-12T21:46:37Z

Move worklist and all worker management fields from global_cwq into the new struct worker_pool. worker_pool points back to the containing gcwq. worker and cpu_workqueue_struct are updated to point to worker_pool instead of gcwq too. This change is mechanical and doesn't introduce any functional difference other than rearranging of fields and an added level of indirection in some places. This is to prepare for multiple pools per gcwq. v2: Comment typo fixes as suggested by Namhyung. Signed-off-by: Tejun Heo Cc: Namhyung Kim

workqueue: add queue_work and activate_work trace points

2010-10-05T08:49:55Z

These two tracepoints allow tracking when and how a work is queued and activated. This patch is based on Frederic's patch to add queue_work trace point. Signed-off-by: Tejun Heo Cc: Frederic Weisbecker

workqueue: prepare for more tracepoints

2010-10-05T08:41:14Z

Define workqueue_work event class and use it for workqueue_execute_end trace point. Also, move trace/events/workqueue.h include downwards such that all struct definitions are visible to it. This is to prepare for more tracepoints and doesn't cause any functional change. Signed-off-by: Tejun Heo Cc: Frederic Weisbecker

workqueue: Add basic tracepoints to track workqueue execution

2010-08-21T20:19:37Z

With the introduction of the new unified work queue thread pools, we lost one feature: It's no longer possible to know which worker is causing the CPU to wake out of idle. The result is that PowerTOP now reports a lot of "kworker/a:b" instead of more readable results. This patch adds a pair of tracepoints to the new workqueue code, similar in style to the timer/hrtimer tracepoints. With this pair of tracepoints, the next PowerTOP can correctly report which work item caused the wakeup (and how long it took): Interrupt (43) i915 time 3.51ms wakeups 141 Work ieee80211_iface_work time 0.81ms wakeups 29 Work do_dbs_timer time 0.55ms wakeups 24 Process Xorg time 21.36ms wakeups 4 Timer sched_rt_period_timer time 0.01ms wakeups 1 Signed-off-by: Arjan van de Ven Signed-off-by: Linus Torvalds

workqueue: temporarily remove workqueue tracing

Strip tracing code from workqueue and remove workqueue tracing. This is temporary measure till concurrency managed workqueue is complete. Signed-off-by: Tejun Heo Cc: Frederic Weisbecker

tracing/workqueue: Use %pf in workqueue trace events

2009-09-22T21:14:58Z

Using %pf instead of %pF supresses printing of the function offset which will always be 0 in the case of worklet functions.
