From ef79e17ccef32599f3cec3842f81d70117181291 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 31 Oct 2014 13:53:52 +0000 Subject: [PATCH] drm/i915: Only mark as map-and-fenceable when bound into the GGTT We use the obj->map_and_fenceable hint for when we already have a valid mapping of this object in the aperture. This hint can only apply to the GGTT and not to the aliasing-ppGTT. One user of the hint is execbuffer relocation, which began to fail when it tried to follow the hint and perform the relocate through the non-existent GGTT mapping.
