Preliminary tests on the 6.5 RC point out that the AMD pstate in an active state is now supported on znver2. However, the parameter CONFIG_X86_AMD_PSTATE_DEFAULT_MODE=3
, which is supposed to autoenable this driver, Does not work for znver2 cpus. (it does seem to work for higher archs)
So please make sure you keep passing the amd_pstate=active
to your kernel to activate pstate on your znver2 CPU, despite of what you might have heared.
EDIT: to be clear: only pass amd_pstate=active
on linux 6.5, on linux 6.4 it is amd_pstate=passive
