Frequency Scaling not Working on AMD Zen 3+ processor with amd-pstate

I have a laptop with an AMD Ryzen 7 6800HS Creator Edition cpu. I have been trying to get amd-pstate working for frequency scaling but to no avail. Currently, I am stuck using acpi-cpufreq, which does not allow for granular control. This means that the cpu is unable to enter a low enough power state to preserve battery life effectively, and is also unable to turbo properly in its highest power state.

I was successfully able to disable the acpi-cpufreq module by blacklisting it in the kernel parameters, following the instructions for my laptop here. I also set the following kernel parameter:

amd_pstate=passive

to enable frequency scaling using amd_pstate following instructions here. However when I do so, cpupower returns an error saying no frequency scaling driver was found. I checked my boot logs and could not find any relevant errors there either. Can someone tell me how to get this working?

Re: Frequency Scaling not Working on AMD Zen 3+ processor with amd-pstate

The info on that wiki page for your laptop is out of date. All you need is amd_pstate=passive, no messing with modules at all. amd_pstate doesn't even exist as a module in Arch.
