From c72c39a851d530c402936f3e6da10e402063a5c9 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 23 Dec 2016 14:57:55 +0000 Subject: [PATCH] drm/i915: Break after walking all GGTT vma in bump_inactive_ggtt Since commit 996f46aca397 ("drm/i915: Store the vma in an rbtree under the object") the vma are once again sorted into GGTT first, then ppGTT so that the typical case of walking the GGTT vma can stop as soon as we find a non-ppGTT. Apply that optimisation.
