From d8a4424839eead6da07835e7d2f8b8f54ad6c6b0 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:08:06 +0100 Subject: [PATCH] drm/i915: Store ggtt pointer in intel_gt This will become useful in the following patch. v2: * Assign the pointer through a helper on the top level to work around the layering violation. (Chris) v3: * Handle selftests. v4: * Move call to intel_gt_init_hw into mock_init_ggtt.
