R9285 on agd5f drm-next-4.15-wip head I get some display glitches, nothing really bad, just the odd lines and a bit of bounce sometimes it seems to be memclk related. Couldn't really bisect as I lock on older versions. I started close to head where I don't lock but below isn't really valid as it turned out that on what I thought were goods were probably only good because memclk is stuck usally but not always high. On head forcing memclk high or low makes the artifacts disappear. This is just the commit that re-enables auto for memclk. commit 76da74965138f4ab32113bf35b67321f4d7c3101 Author: Rex Zhu <Rex.Zhu@amd.com> Date: Thu Sep 14 21:05:18 2017 +0800 drm/amd/powerplay: Add support for CI asics to hwmgr Add support for CI asics (Bonaire, Hawaii) to the powerplay hwmgr
At least I'm not the only one seeing this. Very visible during the Xonotic start screen.
I've independently bisected it to the same commit on drm-next commit 0b6b4cbf77c995a34a4ec3d705a636434dadc51a Author: Rex Zhu <Rex.Zhu@amd.com> Date: Thu Sep 14 21:05:18 2017 +0800 drm/amd/powerplay: Add support for CI asics to hwmgr Add support for CI asics (Bonaire, Hawaii) to the powerplay hwmgr Change-Id: Ia0a31f631dfd717807c16c6c166c994566f644c9 Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Rex Zhu <Rex.Zhu@amd.com>
