Subject: [PATCH v2 2/9] drm/xe: Add timestamp_ms to LRC snapshot
Date: Fri,  1 May 2026 17:53:35 -0700	[thread overview]
Message-ID: <20260502005332.3135977-13-umesh.nerlige.ramappa@intel.com> (raw)
In-Reply-To: <20260502005332.3135977-11-umesh.nerlige.ramappa@intel.com>

From: Matthew Brost <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.
