[PATCH 0/3] Fixes for uclamp and capacity inversion detection

Posted by Qais Yousef 3 years, 2 months ago

From: "Qais Yousef (Google)" <qyousef@layalina.io>

Patch 1 addresses a smatch warning reported by Dan Carpenter.

Patch 2 fixes a couple of issues reported by Dietmar in capacity inversion
logic.

Patch 3 is an RFC patch to decouple capacity inversion detection from
performance domains which is dependent on sched_energy_enabled(). I switched to
traversing cpufreq policies instead. Rafael, Viresh please check I didn't do
something stupid here.


Thanks!
