Bug ID: 102926 Summary: Tonga agd5f drm-next-4.15-wip powerplay display artifacts. 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 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.
