Subject: [Intel-gfx] [PATCH v3 07/10] drm/i915/guc: Apply new uC status tracking to GuC submission as well
Date: Tue, 11 Feb 2020 16:31:21 -0800	[thread overview]
Message-ID: <20200212003124.33844-8-daniele.ceraolospurio@intel.com> (raw)
In-Reply-To: <20200212003124.33844-1-daniele.ceraolospurio@intel.com>

To be able to differentiate the before and after of our commitment to
GuC submission, which will be used in follow-up patches to early set-up
the submission structures.

v2: move functions to guc_submission.h (Michal)
