From mboxrd@z Thu Jan 1 00:00:00 1970 From: Steve Muckle Subject: [PATCH 0/2] utilization changes for schedutil Date: Fri, 26 Aug 2016 11:40:46 -0700 Message-ID: <1472236848-17038-1-git-send-email-smuckle@linaro.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Peter Zijlstra , Ingo Molnar , "Rafael J . Wysocki" Cc: linux-kernel@vger.kernel.org, linux-pm@vger.kernel.org, Vincent Guittot , Morten Rasmussen , Dietmar Eggemann , Juri Lelli , Patrick Bellasi , Steve Muckle List-Id: linux-pm@vger.kernel.org The first patch (which is a re-send) corrects an issue with utilization on SMT platforms. Currently CFS utilization is being roughly doubled on these platforms due to differences in the way PELT and overall max CPU capacity are calculated. The second patch moves away from the policy of going to fmax during RT task activity, instead using rt_avg as an estimate of RT utilization. Steve Muckle (2): sched: cpufreq: ignore SMT when determining max cpu capacity sched: cpufreq: use rt_avg as estimate of required RT CPU capacity kernel/sched/cpufreq_schedutil.c | 26 ++++++++++++++++++-------- 1 file changed, 18 insertions(+), 8 deletions(-) -- 2.7.3
