Subject: [PATCH 04/13] drm/i915/guc: Support per context scheduling policies
Date: Mon, 7 Jun 2021 11:03:46 -0700 [thread overview]
Message-ID: <20210607180356.165785-5-matthew.brost@intel.com> (raw)

From: John Harrison <John.C.Harrison@Intel.com>
GuC firmware v53.0.0 introduced per context scheduling policies. This
includes changes to some of the ADS structures which are required to
load the firmware even if not using GuC submission.
