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 :-)
