Subject: [PATCH v2 0/2] cpufreq: schedutil: Optimize operations in hot path frequency switch
Date:   Wed,  7 Dec 2022 10:17:03 +0000

Hi all,

This v2 is an attempt to optimize some not needed operations in the frequency
change code path for the shared freq. domain. There was different approach
which was too aggressive and failed do to working on a state CPU capacity
information.

changes:
v2:
- split the patch into two (Viresh)
v1:
- simple approach which fetches CPU capacity every time it's needed,
  not relaying on the setup value, which was causing issues.

Regards,
Lukasz
