          Priority: medium
            Bug ID: 82201
          Assignee: dri-devel at lists.freedesktop.org
           Summary: [HAWAII] GPU doesn't reclock, poor 3D performance
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: kai at dev.carbon-project.org
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

No matter what program I run, the clock of the GPU stays:
# cat /sys/kernel/debug/dri/*/radeon_pm_info
power level avg sclk: 30000 mclk: 15000
power level avg sclk: 30000 mclk: 15000

The attached screenshot shows Portal 2 with a GALLIUM_HUD=fps overlay. The ~30
FPS are in the menu, the 8-15 FPS are in the level.

My stack is (base: Debian Testing):
