Subject: [Intel-gfx] [PATCH 03/51] drm/i915/guc: Add LRC descriptor context lookup array
Date: Fri, 16 Jul 2021 13:16:36 -0700 [thread overview]
Message-ID: <20210716201724.54804-4-matthew.brost@intel.com> (raw)
In-Reply-To: <20210716201724.54804-1-matthew.brost@intel.com>
Add LRC descriptor context lookup array which can resolve the
intel_context from the LRC descriptor index. In addition to lookup, it
can determine if the LRC descriptor context is currently registered with
the GuC by checking if an entry for a descriptor index is present.
Future patches in the series will make use of this array.
