Enable amd-pstate CPU Performance Scaling Driver

[benoe77]

Hi, I managed to enable amd-pstate CPU Performance Scaling Driver on our notebook on Ubuntu 22.04 with kernel 5.19 . You need to get into the advanced bios with any of the described method and then enable CPPC control under: Device Manager - AMD CBS - NBIO Common Options - SMU Common Options - CPPC

then you need to add "amd_pstate=passive" to the kernel parameters in /etc/default/grub
After "update-grub" and reboot you can check if it is working by issuing the following: "cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver"
It should show amd_pstates as a result
