* | | | | | power_supply: Add additional USB Type-C propertiesJack Pham2016-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the power_supply_typec_mode enum definitions which will allow a charger to indicate the type of USB Type-C connection that is established. Also add additional properties for indicating CC pin orientation, changing source/sink power role (useful for dynamic power role swap), and a flag to allow the charger to expect VBUS changes during USB Power Delivery power negotiation.

* | | | | | workqueue: implement lockup detectorTejun Heo2016-05-05

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.

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.

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).

Back to 2 -> ICE uses the key that is already invalid 5. 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 overall memory utilization because free cma pages are ignored when memory reclaim is done with gfp mask GFP_KERNEL. Since most memory reclaim is done by kswapd, which uses a gfp mask of GFP_KERNEL, by increasing cma memory utilization we are therefore ensuring that less aggressive memory reclaim takes place. 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.

LMK does not kill a task for the following reasons. 1. The free and file pages are above the LMK thresholds 2. LMK tries to pick task with an adj level corresponding to current thresholds, but fails to do so because of the absence of tasks in that level. But sometimes it is better to kill a lower adj task, than thrashing. And there are cases where the number of file pages are huge, though we dont thrash, the reclaim process becomes time consuming, since LMK triggers will be delayed because of higher number of file pages. Even in such cases, when reclaim path finds it difficult to reclaim pages, it is better to trigger lmk to free up some memory faster. The basic idea here is to make LMK more aggressive dynamically when such a thrashing scenario is detected. To detect thrashing, this patch uses vmpressure events. The values of vmpressure upon which an action has to be taken, was derived empirically. This patch also adds tracepoints to validate this feature, almk_shrink and almk_vmpressure. Two knobs are available for the user to tune adaptive lmk behaviour. /sys/module/lowmemorykiller/parameters/adaptive_lmk - Write 1 to enable the feature, 0 to disable. By default disabled. /sys/module/lowmemorykiller/parameters/vmpressure_file_min - This parameter controls the behaviour of LMK when vmpressure is in the range of 90-94. Adaptive lmk triggers based on number file pages wrt vmpressure_file_min, when vmpressure is in the range of 90-94. Usually this is a pseudo minfree value, higher than the highest configured value in minfree array.
