+commit 389a55581e30607af0fcde6cdb4e54f189cf46cf

+
+ drm/i915: Only clear the GPU domains upon a successful finish
+
+ By clearing the GPU read domains before waiting upon the buffer, we run
+ the risk of the wait being interrupted and the domains prematurely
+ cleared. The next time we attempt to wait upon the buffer (after
+ userspace handles the signal), we believe that the buffer is idle and so
+ skip the wait.
+
+ There are a number of bugs across all generations which show signs of an
+ overly haste reuse of active buffers.
+
+ Such as:
+
+ https://bugs.freedesktop.org/show_bug.cgi?id=29046
+ https://bugs.freedesktop.org/show_bug.cgi?id=35863
+ https://bugs.freedesktop.org/show_bug.cgi?id=38952

+ https://bugs.freedesktop.org/show_bug.cgi?id=41284
+ https://bugs.freedesktop.org/show_bug.cgi?id=42141
+
+ A couple of those pre-date i915_gem_object_finish_gpu(), so may be
+ unrelated (such as a wild write from a userspace command buffer), but
+ this does look like a convincing cause for most of those bugs.
