AMD + Valve Working On New Linux CPU Performance Scaling Design
Along with other optimizations to benefit the Steam Deck, AMD and Valve have been jointly working on CPU frequency/power scaling improvements to enhance the Steam Play gaming experience on modern AMD platforms running Linux.
It's no secret that the ACPI CPUFreq driver code has at times been less than ideal on recent AMD processors with delivering less than expected performance/behavior 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 at large.
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 optimizing the CPU frequency scaling under Linux.
[...] AMD will be presenting more about this effort next month at [the X.Org Developers Conference (XDC)].
X.Org Developer's Conference: XDC2021, Virtual (formerly Gdask, Poland), September 15th through September 17th, 2021.
Previously: Steam Deck is Valve's Switch-Like Portable PC: Starting at $399 this December
