            Bug ID: 100395
           Summary: DC, Powerplay, Tonga, top screen flicker with current
                    amd-staging-4.9
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: adf.lists@gmail.com

R9285 Tonga with current agd5f amd-staging-4.9 I am seeing the top few lines of
single DVI-D 1920x1080 monitor flicker when scrolling in eg, a maximised xterm,
browser also affected but less so.

Forcing clocks high fixes.

Bisect was a failure, I got as far as -

# good: [38eabe8ecaf5fed9e8122091b27b406563daa2ad] drm/amdgpu: add the HDP 4.0
register headers

# bad: [e2f744ea6cba6a2a7d938ec89def196a59dbdd2d] drm/amdgpu/gfx9: correct wptr
pointer value

IIRC said 40 something commits to go.

The next 20 or so are all skips because I got either build fails or startx
hangs.

Gave up with the intention of doing git reset --hard
e2f744ea6cba6a2a7d938ec89def196a59dbdd2d and going backwards, but as the
history after doing that was totally different from as seen from head I didn't
bother :-)
