Re: [PATCH v2 0/2] sched/cpufreq: fix schedutil's boost frequency handling

[Oleg Keri]

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.
