[PATCH] drm/radeon/kms: disable writeback on pre-R300 asics

2012-01-03 Thread alexdeuc...@gmail.com
From: Alex Deucher We often end up missing fences on older asics with writeback enabled which leads to delays in the userspace accel code, so just disable it by default on those asics. Reported-by: Helge Deller Reported-by: Dave Airlie Signed-off-by: Alex Deucher Cc: stable at vger.kernel.org
