Subject: drm/i915/guc: Remove USES_GUC_SUBMISSION for ads programming
Git-commit: aa58f58d9c6471a1087ede57e4ab6cc0817c949f
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
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. (Daniele)
