+Querying Device Statistics
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The statistics from the IDXD dmadev device can be got via the stats functions
in
+the ``rte_dmadev`` library, i.e. ``rte_dmadev_stats_get()``. The statistics
+returned for each device instance are:
+
+* ``submitted_count``
+* ``completed_fail_count``
+* ``completed_count``
