Subject: [PATCH v2 2/6] drm/xe: Add helper to capture engine timestamp
Date: Tue, 23 Apr 2024 16:56:47 -0700 [thread overview]
Message-ID: <20240423235652.1959945-3-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20240423235652.1959945-1-lucas.demarchi@intel.com>
Just like CTX_TIMESTAMP is used to calculate runtime, add a helper to
get the timestamp for the engine so it can be used to calculate the
"engine time" with the same unit as the runtime is recorded.
