[PATCH] cpufreq: dt: Set default policy->transition_delay_ns

by Viresh Kumar

The rate_limit_us for the schedutil governor is getting set to 500 ms by default for the ARM64 hikey board. And its way too much, even for the default value. Lets set the default transition_delay_ns to something more realistic (10 ms), while the userspace always have a chance to set something it wants.

[PATCH 0/6] sched: Minor fixes and cleanups

by Viresh Kumar

Hi, The first patch fixes a potential regression we may observe on the UP systems and the others are doing minor optimizations in the scheduler core. They are all tested on ARM 32 (exynos) and 64 (hikey) bit platforms. -- viresh Viresh Kumar (6): sched: fair: Call cpufreq update util handlers less frequently on UP sched: Reuse put_prev_task() sched: fair: Pass rq to weighted_cpuload() sched: fair: Avoid checking cfs_rq->nr_running twice sched: fair: Drop always true parameter of update_cfs_rq_load_avg() sched: cpufreq: Optimize cpufreq_update_this_cpu() a bit kernel/sched/core.c | 2 +- kernel/sched/fair.c | 107 ++++++++++++++++++++++++++------------------------- kernel/sched/sched.h | 2 +- 3 files changed, 56 insertions(+), 55 deletions(-) -- 2.13.0.70.g6367777092d9

[GIT PULL][lsk-v4.4-android] linaro-android v4.4 topic branch updates

by Amit Pundir

Hi Alex, Please consider following linaro-android pull request for "linux-linaro-lsk-v4.4-android" LSK branch. KernelCI link is down for linaro-android trees and didn't do much of local build testing either. Shamelessly relying on KernelCI build bot results for linux-linaro-lsk-v4.4-android tree for any breakage reporting. Boot tested on Qemu(vexpress defconfig + android config fragments) + Android M userspace. Regards, Amit Pundir The following changes since commit be74fd2af86d551009c7a47d4884f29349d59193: Merge branch 'linux-linaro-lsk-v4.4' into linux-linaro-lsk-v4.4-android (2017-06-08 12:11:52 +0800) are available in the git repository at: git://android.git.linaro.org/kernel/linaro-android lsk-v4.4-android for you to fetch changes up to cb41d236c7cdb4f91a1699a14a3600ec5bf4759d: ANDROID: sdcardfs:
