From 7226572d8ed48f7e1aa9de5383d919490d6e9a0c Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Wed, 7 Jan 2015 17:32:39 +0000 Subject: [PATCH] drm/i915: Reserve shadow batch VMA analogue to others If not pinned VMA can become an eviction target just before it needs to be executed which breaks the internal object lifetime rules.
