This is a note to let you know that I've just added the patch titled
cpufreq: amd-pstate: Enable amd-pstate preferred core support
to the 6.6-stable tree

No way this is a stable material. What a joke.

@oleksandr

So a ~35% performance regression on an AMD EPYC 7702 should be left unfixed?

You could have found this IMHO valid reason within seconds if you had searched for the patch title on lore.

If backporting the change that caused this regression was wise is a different question though (I did not check at all).

@kernellogger I was among the earliest tester of this feature, and all I can say it's a complex patchset, and I have doubts it's a stable material. No need to be passive aggressive.

@oleksandr Third of patches in stable don't match published rules. One solution would be updating stable-kernel-rules...
