Amd pstate on 6.1 on 4700u

Has someone ever enabled amd pstate on lenovo ideapd slim 5 (14are05) , AMD 4700u model ?

I am trying to get it on on linux kernel 6.1
i tried this

but just this doesnt work for me

  • How did you configure?
  • Did you run $ sudo update-grub when using GRUB, then reboot?

Is CPPC available and activated in the UEFI?

yes i did run the grub update command and rebooted

i didnt find any option like that in bios
but lscpu has it in flags
