* workqueue: implement lockup detectorTejun Heo2016-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Workqueue stalls can happen from a variety of usage bugs such as missing WQ_MEM_RECLAIM flag or concurrency managed work item indefinitely staying RUNNING. These stalls can be extremely difficult to hunt down because the usual warning mechanisms can't detect workqueue stalls and the internal state is pretty opaque. To alleviate the situation, this patch implements workqueue lockup detector. It periodically monitors all worker_pools periodically and, if any pool failed to make forward progress longer than the threshold duration, triggers warning and dumps workqueue state as follows. BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck for 31s! Showing busy workqueues and worker pools: workqueue events: flags=0x0 pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=17/256 pending: monkey_wrench_fn, e1000_watchdog, cache_reap, vmstat_shepherd, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, release_one_tty, cgroup_release_agent workqueue events_power_efficient: flags=0x80 pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=2/256 pending: check_lifetime, neigh_periodic_work workqueue cgroup_pidlist_destroy: flags=0x0 pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=1/1 pending: cgroup_pidlist_destroy_work_fn ... The detection mechanism is controller through kernel parameter workqueue.watchdog_thresh and can be updated at runtime through the sysfs module parameter file. v2: Decoupled from softlockup control knobs.

* watchdog: introduce touch_softlockup_watchdog_sched()Tejun Heo2016-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | touch_softlockup_watchdog() is used to tell watchdog that scheduler stall is expected. One group of usage is from paths where the task may not be able to yield for a long time such as performing slow PIO to finicky device and coming out of suspend. The other is to account for scheduler and timer going idle. For scheduler softlockup detection, there's no reason to distinguish the two cases; however, workqueue lockup detector is planned and it can use the same signals from the former group while the latter would spuriously prevent detection. This patch introduces a new function touch_softlockup_watchdog_sched() and convert the latter group to call it instead. For now, it just calls touch_softlockup_watchdog() and there's no functional difference.

* sched: add support for CPU frequency estimation with cycle counterJoonwoo Park2016-04-27
| | | | | | | | | | | | | | | | | | At present scheduler calculates task's demand with the task's execution time weighted over CPU frequency. The CPU frequency is given by governor's CPU frequency transition notification. Such notification may not be available. Provide an API for CPU clock driver to register callback functions so in order for scheduler to access CPU's cycle counter to estimate CPU's frequency without notification. At time point scheduler assumes the cycle counter increases always even when cluster is idle which might not be true. This will be fixed by subsequent change for more accurate I/O wait time accounting.

* drivers/perf: arm_pmu: implement CPU_PM notifierLorenzo Pieralisi2016-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a CPU is suspended (either through suspend-to-RAM or CPUidle), its PMU registers content can be lost, which means that counters registers values that were initialized on power down entry have to be reprogrammed on power-up to make sure the counters set-up is preserved (ie on power-up registers take the reset values on Cold or Warm reset, which can be architecturally UNKNOWN). To guarantee seamless profiling conditions across a core power down this patch adds a CPU PM notifier to ARM pmus, that upon CPU PM entry/exit from low-power states saves/restores the pmu registers set-up (by using the ARM perf API), so that the power-down/up cycle does not affect the perf behaviour (apart from a black-out period between power-up/down CPU PM notifications that is unavoidable).

* drivers/perf: kill armpmu_registerMark Rutland2016-04-27
| | | | | | | | | | | | | | | | | | | | | | | | Nothing outside of drivers/perf/arm_pmu.c should call armpmu_register any more, so it no longer needs to be in include/linux/perf/arm_pmu.h. Additionally, by folding it in to arm_pmu_device_probe we can allow drivers to override struct pmu fields without getting blatted by the armpmu code. This patch folds armpmu_register into arm_pmu_device_probe. The logging to the console is moved to after the PMU is successfully registered with the core perf code.

Crash due to PARTIALLY_SET_KEY_USED To fix this, pfk must know when requests using some key are completed. Only then key removal shall be allowed and until then key invalidation must wait. A new callback was added to let clients inform PFK when requests end.

Increased cma memory utilization will improve performance, for example it will increase app concurrency.

If CMA pages are utilized poorly, non-movable allocations may end up getting starved if all regular movable pages are allocated and the only pages left are CMA. Always using CMA pages first creates unacceptable performance problems. As a midway alternative, use CMA pages for certain userspace allocations. The userspace pages can be migrated or dropped quickly which giving decent utilization.

* msm_serial_hs: Fix race condition blocking suspend and remove wakeup sourceGirish Mahadevan2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | The __pm_stay_awake/relax() calls were moved to runtime callbacks as a means to fix data loss due to race conditions between incoming userspace commands and executing PM related callbacks. However calling the __pm_relax (to notify wakeup event processing) as part of the runtime suspend callback could be race prone between the system suspend and the runtime framework. If the system suspend gets to run before the runtime callback, the wakeup event will block system suspend. Remove the use of the wakeup source altogether, instead do these: 1. Block system suspend based on the current clk request count and the RPM state of the device (to detect potential inbound userspace requests). 2. If the driver is in the process of executing the system suspend callback, ignore any userspace requests. 3. If the client calls a shutdown without an unvote ioctl, zero out the client_count vote forcefully to allow suspend.

| | | | | | | | | | | | | | | Since msmcobalt RUMI uses QRBTC-V2 UFS PHY, there are a few limitations that must be applied in order to be able to initialize UFS: 1. UFS should remain in PWM-G1 1-Lane and never change its gear, as other gears are not stable 2. hibern8 enter/exit should be bypassed 3. we should avoid any power change (as in runtime suspend/resume) Add "qcom,disable-lpm" property to facilitate disabling of these.

* sched: restrict sync wakee placement bias with waker's demandJoonwoo Park2016-03-23
| | | | | | | | | | | | | | | | | | Biasing sync wakee task towards waker CPU's cluster makes sense when the waker's demand is high enough so the wakee also can take advantage of high CPU frequency voted because of waker's load. Placing sync wakee on the low demand waker's CPU can lead placement imbalance which can lead unnecessary migration. Introduce a new tunable "sched_big_waker_task_load" that defines the big waker so scheduler avoid wakee on waker's cluster bias when the waker's load is below the tunable.
