From ab84a110490d38d40780113a1cdfce03b1cdec13 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 19 Jul 2018 20:47:45 +0100 Subject: [PATCH] drm/i915/selftests: Use a full emulation of a user ppgtt context To test eviction from a ppgtt, we just want a ppgtt i.e. something other than the Global GTT which is shared and used by the kernel for HW features like fencing and scanout. However, we also need it to pass !i915_is_ggtt() and the simplest way is to emulate a full user context rather than the internal kernel context that is used for the GGTT.
