Many OEM platform provide a platform profile knob that can be used to make firmware tunings to the system to allow operating in a higher or lower performance mode trading off power consumption. Software like power-profiles-daemon to expose this knob to the UI. As we know the user's intent to go into power saving or performance mode from this, we can also let amdgpu react to the change. This patch series is sent as RFC right now only to amd-gfx, and if it's a good enough idea will re-send as PATCH to linux-acpi + amd-gfx.
