How to enable amd_pstate for AMD Zen 2+ and Linux Kernel 5.17 or 5.18 only

  1. Edit /etc/mkinitcpio.conf to add
MODULES=(amd_pstate)

  1. sudo mkinitcpio -P linux

  2. Edit /etc/default/grub to add it in GRUB_CMDLINE_LINUX_DEFAULT:

amd_pstate.shared_mem=1

  1. sudo update-grub

  2. reboot.

  3. Enable CPPC in BIOS setting.

It works for me in Linux Kernel 5.18:

❯ sudo cpupower frequency-info                                                                                                                                                                                            
analyzing CPU 0:
  driver: amd-pstate
