[PATCH RESEND 0/3] cstate support for CWF, LNL and PTL

Posted by Zide Chen 3 months, 2 weeks ago

This series resends three c-state patches that have been posted for a
few months but have not yet received feedback.

On behalf of Rui, I’ve included his two patches here, so that all
outstanding Intel c-state related patches can be reviewed together.

There are no code changes in this resend. Only the changelog in
[PATCH 1/3] has been updated to note that the C1E counter can only
be read via PMT.

Zhang Rui (2):
  perf/x86/intel/cstate: Remove PC3 support from LunarLake
  perf/x86/intel/cstate: Add Pantherlake support

Zide Chen (1):
  perf/x86/intel/cstate: Add Clearwater Forest support

The whole patch series looks good to me.
