enable AMD P-state on Family 17h (threadripper zen 2)

[CountDizzy]

This is a known issue affecting a small portion of zen 2 users.

https://bugzilla.kernel.org/show_bug.cgi?id=218171

There is a series of patches that could help as well:

The patches are tentatively slated to reach mainline for the 6.9 release.

I have tested the initial patch with TKG, and can confirm that it does enable p-state.

I went to the thread and read the entirety of it. Was heartwarming to see it figured out in the end haha.

Basically AMD guy kept saying it's the Mobo guys who are at fault until he took a serious look at it and asked to right people to understand that actually that the Mobo wasn't at fault haha. Needed many people to chim in and report the same error for different Mobo vendors.

Does the patch affect every zen2 user or only zen2 thread ripper ?

only thread ripper

So I think you can submit a PR to the community repo for it, then you can add its filename in customization.cfg in the _community_patches variable
