From 9a6bbb62161a3b7b124ecd8325a928778dfcd67e Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 14 Feb 2014 14:01:15 +0100 Subject: [PATCH] drm/i915: Don't pin the status page as mappable We access it through the cpu window. No functional difference expected atm since we default to a bottom-up allocation scheme. But that might eventually change so that we prefer the unmappable range for buffers that don't need cpu gtt access. Split out from Chris vma-bind rework. Note that this is only possible due to the split-up of the mappable pin flag into PIN_GLOBAL and PIN_MAPPABLE.
