From aa58f58d9c6471a1087ede57e4ab6cc0817c949f Mon Sep 17 00:00:00 2001 From: Anusha Srivatsa Date: Fri, 22 Jun 2018 11:19:03 -0700 Subject: [PATCH] drm/i915/guc: Remove USES_GUC_SUBMISSION for ads programming In the guc_ctl_debug_flags, the ads struct is programmed only when USES_GUC_SUBMISSION is satisfied. But, this has to be programmed for all suspend/resume cases. Remove the condition and program the ads struct for both huc loading and guc submission. This issue was noticed when CI threw errors for enable_guc=2 (load huc; disable submission) v2: - Change commit title. - Correct the shifts.
