From: Chris Wilson Date: Fri, 20 Nov 2015 14:16:39 +0000 (+0000) Subject: drm/i915: Set the map-and-fenceable flag for preallocated objects X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d0710abbcd88b1ff17760e97d74a673e67b49ea1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Set the map-and-fenceable flag for preallocated objects As we mark the preallocated objects as bound, we should also flag them correctly as being map-and-fenceable (if appropriate!) so that later users do not get confused and try and rebind the pinned vma in order to get a map-and-fenceable binding.
