AMD and Valve are working on CPU frequency/power scaling improvements to enhance the Steam Play gaming experience on modern AMD platforms running Linux.
There is an issue with the ACPI CPUFreq driver code has at times been less than ideal on recent AMD processors with delivering less than expected performance with being slow to ramp up to a higher performance state or otherwise coming up short of disabling the power management functionality outright.
AMD hasn't traditionally worked on the Linux CPU frequency scaling code as much as Intel does to their P-State scaling driver and other areas of power management AMD is ramping up efforts in these areas including around the Linux scheduler given their recent hiring spree while it now looks like thanks to the Steam Deck there is renewed interest in better optimising the CPU frequency scaling under Linux.
