amd pstate

[farchanjo]

Guys,

I'm running a 7950x virtualized (proxmox) at my home with kernel 6.2.13 and amd_pstate=passive. I'm getting good frequencies from processor, someone is running a higher kernel where amd_pstate=active?

Active is only supported since 6.3 . I m currently running passive since 1month, pretty stable.

is possible compile vanilla kernel for testing this feature? I'd like to do some performance test using this scaling.
