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.li...@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.
