Hi, This patchset makes the cpufreq_cooling driver reuse the CPU utilization metric provided by the scheduler instead of depending on idle and busy times of a CPU, which aren't that accurate to measure the busyness of a CPU for the next cycle. More details can be seen in the commit log of patch 2/2.
V2->V3: - Put the scheduler helpers within ifdef CONFIG_SMP. - Keep both SMP and !SMP implementations in the cpufreq_cooling driver. - Improved commit log with testing related information. -- Viresh Viresh Kumar (2): sched/core: Rename and move schedutil_cpu_util() to core.c thermal: cpufreq_cooling: Reuse sched_cpu_util() for SMP platforms drivers/thermal/cpufreq_cooling.c | 68 ++++++++++++++---- include/linux/sched.h | 21 ++++++ kernel/sched/core.c | 115 +++++++++++++++++++++++++++++ kernel/sched/cpufreq_schedutil.c | 116 +----------------------------- kernel/sched/fair.c | 6 +- kernel/sched/sched.h | 31 +------- 6 files changed, 199 insertions(+), 158 deletions(-) base-commit: 3650b228f83adda7e5ee532e2b90429c03f7b9ec -- 2.25.0.rc1.19.g042ed3e048af
