            Bug ID: 221004
           Summary: After some hours FPS drop to half while gaming using
                    amdgpu driver with wayland
           Product: Drivers
           Version: 2.5
          Hardware: AMD
                OS: Linux
            Status: NEW
          Severity: high
          Priority: P3
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: quanticcpu2100@gmail.com
        Regression: No

For some reason, in the Wayland session, after a few hours, the frame rate
drops by half in all games using the amdgpu driver. It seems that after playing
for a long time, the amdgpu driver changes the GPU clock to the minimum
profile, and the memory goes into idle or has a low clock speed. I ran the
command below now when the problem is occurring during the game to help provide
some information related to the problem.
