There the update to HEAD was delayed until after our checks. In drm-intel-nightly, there is commit 95468892fdfeef6d1004b524e35957629efdbe00 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Thu Aug 7 15:39:54 2014 +0100 drm/i915: Reset the HEAD pointer for the ring after writing START Ville found an old w/a documented for g4x that suggested that we need to reset the HEAD after writing START. This is a useful fixup for some of the g4x ring initialisation woes, but as usual, not all. v2: Do the rewrite unconditionally anyway References: <a class="bz_bug_link bz_status_REOPENED " title="REOPENED --- - [gm45] [drm:init_ring_common]: *ERROR* render ring initialization failed" href="show_bug.cgi?id=76554">https://bugs.freedesktop.org/show_bug.cgi?id=76554</a> Signed-off-by: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Cc: Ville Syrjälä <<a href="mailto:ville.syrjala@linux.intel.com">ville.syrjala@linux.intel.com</a>> Reviewed-by: Ville Syrjälä <<a href="mailto:ville.syrjala@linux.intel.com">ville.syrjala@linux.intel.com</a>> Signed-off-by: Daniel Vetter <<a href="mailto:daniel.vetter@ffwll.ch">daniel.vetter@ffwll.ch</a>> which should be the right fix.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
