So I wanted to give you some feedback for this, from the scheduler maintainer's
POV.
Looks like there are two cpufreq modernization efforts, one is this series, the
other is Steve Muckle's:
[RFCv7 PATCH 00/10] sched: scheduler-driven CPU frequency selection
What I'd like to see from a scheduler metrics usage POV is a single central place,
kernel/sched/cpufreq.c, where all the high level ('governor') decisions are made.
This is the approach Steve's series takes.
That is a central point that has ready access to the scheduler internal
utilization metrics.
drivers/cpufreq/ would contain legacy governors plus low level drivers that do
frequency switching with a well-defined interface.
Could you guys work out a single series that implements the sum of the two series?
Looks like we are 90% 'there' already.
Thanks,
Ingo
