<pre>Hi, apologies for the long delay - a bad case of Man Flu has knocked me out for
the past week.
On Sunday I produced three test builds for JP based on drm-tip[1]:
"drm-tip: 2017y-11m-12d-14h-36m-14s UTC integration manifest"
The three builds were:
#1113b: drmtip only
#1113c: #1113b + Chris Wilson patch (<a href="show_bug.cgi?id=102818#c17">comment 17</a>)
#1113d: #1113b + my hack patch (<a href="show_bug.cgi?id=102818#c11">comment 11</a>)
After testing, JP has called all three builds as "GOOD", as none are exhibiting
the Z-shaped corruption. Therefore it doesn't look like any additional patches
from this bug are required.
However a different build (exact same userland but with drm-tip replaced by the
mainline 4.14 kernel released on Sunday, and no patches from this bug)
continues to show the Z-shaped corruption, so the corruption issue is still
present in the mainline 4.14 kernel.
Maybe this issue will be fixed in 4.15?
