 Once configured, the device can then be made ready for use by calling the
 ``rte_dmadev_start()`` API.
+
+Performing Data Copies
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To perform data copies using IOAT dmadev devices, the functions
+``rte_dmadev_copy()`` and ``rte_dmadev_submit()`` should be used. Alternatively
+``rte_dmadev_copy()`` can be called with the ``RTE_DMA_OP_FLAG_SUBMIT`` flag
+set.
+
+The ``rte_dmadev_copy()`` function enqueues a single copy to the
+device ring for copying at a later point. The parameters to the function
+include the device ID of the desired device, the virtual DMA channel required
+(always 0 for IOAT), the IOVA addresses of both the source and destination
+buffers, the length of the data to be copied and any operation flags. The
+function will return the index of the enqueued job which can be use to
+track that operation.
+
+While the ``rte_dmadev_copy()`` function enqueues a copy operation on the device
+ring, the copy will not actually be performed until after the application calls
+the ``rte_dmadev_submit()`` function. This function informs the device hardware
+of the elements enqueued on the ring, and the device will begin to process them.
+It is expected that, for efficiency reasons, a burst of operations will be
+enqueued to the device via multiple enqueue calls between calls to the
+``rte_dmadev_submit()`` function. If desired you can pass the
+``RTE_DMA_OP_FLAG_SUBMIT`` flag when calling ``rte_dmadev_copy()`` and this will
+tell the device to perform the enqueued operation and any unperformed operations
+before it. The ``RTE_DMA_OP_FLAG_SUBMIT`` flag can be passed instead of calling
+the ``rte_dmadev_submit()`` function for example on the last enqueue of the burst.
+
+The following code from demonstrates how to enqueue a burst of copies to the
+device and start the hardware processing of them:
+
+.. code-block:: C
+
+   for (i = 0; i < BURST_SIZE; i++) {
+      if (rte_dmadev_copy(dev_id, vchan, rte_mbuf_data_iova(srcs[i]),
+            rte_mbuf_data_iova(dsts[i]), COPY_LEN, 0) < 0) {
+         PRINT_ERR("Error with rte_dmadev_copy for buffer %u\n", i);
+         return -1;
+      }
+   }
+   if (rte_dmadev_submit(dev_id, vchan) < 0) {
+      PRINT_ERR("Error with performing operations\n", i);
+      return -1;
+   }
+
+Filling an Area of Memory
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The driver also has support for the ``fill`` operation, where an area
+of memory is overwritten, or filled, with a short pattern of data.
+Fill operations can be performed in much the same was as copy operations
+described above, just using the ``rte_dmadev_fill()`` function rather
+than the ``rte_dmadev_copy()`` function.
