From e43ff99c8deda85234e6233e0f4af6cb09566a37 Mon Sep 17 00:00:00 2001 From: Umesh Nerlige Ramappa Date: Thu, 9 Jul 2020 23:45:03 +0100 Subject: drm/i915/perf: Use GTT when saving/restoring engine GPR MI_STORE_REGISTER_MEM and MI_LOAD_REGISTER_MEM need to know which translation to use when saving restoring the engine general purpose registers to and from the GT scratch. Since GT scratch is mapped to ggtt, we need to set an additional bit in the command to use GTT.
