[Intel-gfx] regression after: drm/i915: Warn if we run out of FIFO space for a mode
Hallo all, i have regression coused by this patch: commit b9421ae8f30958deea98d71477b4a77a066856b4 Author: Chris Wilson ch...@chris-wilson.co.uk Date: Mon Jul 19 21:46:08 2010 +0100 drm/i915: Warn if we run out of FIFO space for a mode Signed-off-by: Chris Wilson ch...@chris-wilson.co.uk Cc: Jesse Barnes jbar...@virtuousgeek.org Signed-off-by: Eric Anholt e...@anholt.net If i start openarena, i'll get black background with big mousepointer (it can be moved).
