Description
I've observed that on the Steam Deck, changes to the AMD p-state driver can have a significant impact on tail latencies and stale frame numbers. I've submitted an RFC upstream which proposes a per-CPU EPP boost heuristic: https://lore.kernel.org/all/20260728073150.54964-1-void@manifault.com/.
We should discuss gaps in the current cpufreq / AMD p-state driver, and how to best address frequency scaling for gaming workloads in general.
