Amd p-state on the 6.11 kernel

General
1

There’s a new driver in the new kernel. Do we need to do something to enable proper functionality for this driver?

currently I don’t have anything in my grub config, I remeber you used to need to add something to enable it

GRUB_CMDLINE_LINUX_DEFAULT='nowatchdog nvme_load=YES zswap.enabled=0 splash quiet resume=UUID=f68c4fc7-2d63-4322-bd13-55cdd1e71973 loglevel=3'

Which Driver?

 cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
amd-pstate-epp

My Grub

GRUB_DISTRIBUTOR='CachyOS'
GRUB_CMDLINE_LINUX_DEFAULT='nowatchdog nvme_load=YES zswap.enabled=0 splash splash loglevel=3'
GRUB_CMDLINE_LINUX="lsm=landlock,lockdown,yama,integrity,apparmor,bpf"

Kernel “6.11.0-rc7-2-cachyos-rc”

I guess I should have been more specific, See @naim post below

Don’t need anything.

cpupower frequency-info in the console will tell you if you are running amd pstate driver or not.
