No STR was given, from the lack of info I believe it's just a general case, e.g. if you run `stress-ng -c $(nproc)`, you *should* see the issue (entire= ly speculation). This regression only happens with the active driver. Both pas= sive and guided mode was reported to behave correctly. I can't reproduce this either because my laptop is a Zen3 laptop. It is lik= ely that it is limited to Zen2. > 2.

Yes, you can see the related tree https://github.com/CachyOS/linux/tree/6.14/amd-pstate. It's not 1:1 with Mario's tree but I diffed both trees and the only difference was commit 34562659110a42276d63f8b5a9d522d2400b2df2 which is from the "Dynamic ITMT co= re ranking support" series. >=20 > Thanks,=20 > Dhananjay --=20 You may reply to this email to add a comment.
