Subject: [PATCH V2 0/3] perf/x86/intel/cstate: Update for latest client platforms
There are a couple of cstate changes on latest Intel client platforms.
Alderlake platform, followed by Raptorlake, Meteorlake and Arrowlake,
doesn't have PC7/PC9.
Lunarlake platform doesn't have PC7/PC8/PC9.
Fix current code and update support for new platforms.
Patch 1/3 fixes Alderlake/Raptorlake/Meteorlake by removing PC7/PC9
support.
Patch 2/3 adds Arrowlake support, which behaves the same as Alderlake.
Patch 3/3 adds Lunarlake support, which behaves similar to Alderlake,
but with PC8 removed.
Patch V1 has been posted at
