Daniel Vetter ffd93f2480 drm/i915: Work-around garbage DR4 from UXA ... Somehow UXA submits a completely bogus DR4 value since essentially forever. It was originally introduced in commit bade7d7d2505a10a8a7d24b084aff9742e2d6d64 Author: Eric Anholt <eric@anholt.net> Date: Fri Jun 6 14:03:25 2008 -0700 Use the DRM for submitting batchbuffers when available. and dutifully copied around ever since. Since we want to keep the general dirt catching around just special case the UXA value. This regression was introduced in commit 9cb346648d Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Apr 24 08:09:11 2014 +0200 drm/i915: Catch dirt in unused execbuffer fields Comment from Chris' review: "To be fair, it is a sensible value if one supposes a Region style API to cliprects. Under that API, DR[14] define the extents of the clip region, and ((0,0), (0,0)) [DR1==DR4==0] would mean all clipped, do not draw anything." v2: Pimp commit message a bit and remove the double space.
