Subject: Re: [PATCH v2 0/2] sched/cpufreq: fix schedutil's boost frequency handling
Date: Thu, 17 Sep 2026 18:05:06 +0200 [thread overview]
Message-ID: <178966110618.2386.17602156528185920946@gmail.com> (raw)
In-Reply-To: <20260908-schedutil-boost-frequency-handling-v2-0-25312a713699@oss.qualcomm.com>
Hi Ananthu,
Tested both patches on a Lenovo Yoga Slim 7x Gen 11 (Glymur,
scmi-cpufreq) on top of next-20260915.
1/2: with boost off at boot the little cores get cpu_capacity=553,
which matches the 4723200 boost maximum as the reference (4032000
would give 647). A workload pinned to cpu6 runs at 4032000 with boost
off and 4723200 with boost on, 3.14 s against 2.50 s.
2/2:
# cat policy6/scaling_max_freq
4032000
# echo 1 > boost
# cat policy6/scaling_max_freq
4723200
# echo 0 > boost
# cat policy6/scaling_max_freq
4032000
One observation: policy6/cpuinfo_max_freq still reads 4723200 after
boost is switched off again.
