#2 amd-cpufreq driver
Closed 4 months ago by kylegospo. Opened 4 months ago by kylegospo.

Hi, I noticed you recently added the AMD CPPC patches to this Kernel. I'm curious how we enable the amd-cpufreq scaling driver exposed by that patch set. I don't see it as one of the available drivers and I am still using acpi-cpufreq as the default in 5.15.16-201.fsync.fc35.x86_64


Got it working, for anyone else in my position:

sudo modprobe amd-pstate
sudo grubby --update-kernel=ALL --args="amd_pstate=enable"

Depending on your CPU you may also need:
sudo grubby --update-kernel=ALL --args="amd_pstate.shared_mem=1"

I also recommend changing from ondemand to schedutil if you do this.
