I’m having a bit of difficulty getting amd_pstate to work (again). On the previous stable update with kernel 5.17.x I got it working, but noticed on a previous testing update that a new /etc/mkinitcpio.conf change was needed, otherwise it switches back to acpi-cpufreq.
I’ve updated to today’s stable, running kernel 5.18.3, checked cpupower frequency-info, and it says acpi-cpufreq. I tried following the instructions in the testing thread for adding amd_pstate to the MODULES section of mkinitcpio.conf, but when running the “sudo mkinitcpio -P linux” command I get this: ==> ERROR: module not found: amd_pstate for each kernel. I undid the suggestions in the testing thread as a precaution.
I tried the instructions for modifying mkinitcpio.conf before updating to this stable release as a test, and had the same error results.
My processor is a Zen 2, Ryzen 7 3800X, /etc/default/grub has the amd_pstate.enable=1 and amd_pstate.shared_mem=1.
Any suggestions?
