Subject: [RFC PATCH 86/97] drm/i915/guc: Add golden context to GuC ADS
Date: Thu, 6 May 2021 12:14:40 -0700 [thread overview]
Message-ID: <20210506191451.77768-87-matthew.brost@intel.com> (raw)
In-Reply-To: <20210506191451.77768-1-matthew.brost@intel.com>
From: John Harrison <John.C.Harrison@Intel.com>
The media watchdog mechanism involves GuC doing a silent reset and
continue of the hung context. This requires the i915 driver provide a
golden context to GuC in the ADS.
