soc: qcom: rq_stats: Always show idle time left The def_timer_ms file indicates how much time has passed since we wrote to the file to start the timer, but the time is only updated when the work runs, instead of on demand when the file is read. If we're poll(3)ing this file and another file and the other file wakes our process up from sleep we won't know without measuring time ourselves. Make this easier on userspace by always showing the amount of time since we wrote the file so that we can figure out how long we were asleep for.

rq_stats: Doing rq_stats calculation in the scheduler tick. With this change, we do the average run queue statistics calculation in the scheduler tick itself. This helps avoid any extra timers to do the same. Also doing this calculation in the scheduler tick avoids any bias if the calculation is done in a workqueue Change-Id: I854d90acc05cc7a7226487be5555976826d8c837 Signed-off-by: Amar Singhal <asinghal@codeaurora.org> (cherry picked from commit f49d99bc4168c7937655bb09989cc72525163b40)

msm:rq_stats: Add hotplug disable attribute Register for suspend and resume notifications from kernel. This should be done as part of core_initcall so as to receive notification as close as possible to the actual event. Add hotplug_disable attribute to rq-stats node. Set/clear this attribute based on the suspend/resume events. CRS-fixed: 452456 Change-Id: I76fee349b57f47df40785e9c2503e2e1cc6e064e Signed-off-by: Archana Sathyakumar <asathyak@codeaurora.org>
