Subject: [PATCH v2 18/22] drm/xe: Add timestamp_ms to LRC snapshot
Date: Sun,  4 Jan 2026 20:02:33 -0800	[thread overview]
Message-ID: <20260105040237.1307873-19-matthew.brost@intel.com> (raw)
In-Reply-To: <20260105040237.1307873-1-matthew.brost@intel.com>

Add a timestamp in milliseconds to the LRC snapshot to make it easier to
reason about how long the LRC has been running and the average duration
of each job.
