Chris Wilson 8b6124a633 drm/i915: Don't access snooped pages through the GTT (even for error capture) ... We want to use the GTT for reading back objects upon an error so that we have exactly the information that the GPU saw. However, it is verboten to access snoopable pages through the GTT and causes my PineView GPU to throw a page fault instead. This has not been a problem in the past as we only dumped ringbuffers and batchbuffers, both of which must be not snooped. However, the introduction of HWS page dumping leads to a read of a snooped object through the GTT. This was introduced by commit f3ce382139 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jan 23 22:40:36 2014 +0000 drm/i915: Include HW status page in error capture Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> [danvet:s/uncached/not snooped/ for one case in the commit message as requested by Chris.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2014-01-30 17:25:39 +01:00
