 Silent mode is a special device capability which does not require the

+Enqueue / Dequeue APIs
+~~~~~~~~~~~~~~~~~~~~~~
+
+Enqueue APIs such as ``rte_dma_copy`` and ``rte_dma_fill`` can be used to
+enqueue operations to hardware. If an enqueue is successful, a ``ring_idx`` is
+returned. This ``ring_idx`` can be used by applications to track per operation
+metadata in an application-defined circular ring.
+
+The ``rte_dma_submit`` API is used to issue doorbell to hardware.
+Alternatively the ``RTE_DMA_OP_FLAG_SUBMIT`` flag can be passed to the enqueue
+APIs to also issue the doorbell to hardware.
+
+There are two dequeue APIs ``rte_dma_completed`` and
+``rte_dma_completed_status``, these are used to obtain the results of the
+enqueue requests. ``rte_dma_completed`` will return the number of successfully
+completed operations. ``rte_dma_completed_status`` will return the number of
+completed operations along with the status of each operation (filled into the
+``status`` array passed by user). These two APIs can also return the last
+completed operation's ``ring_idx`` which could help user track operations within
+their own application-defined rings.

  * Finally, an application can close a dmadev by invoking the rte_dma_close()
  * function.
  *
+ * The dataplane APIs include two parts:
+ * The first part is the submission of operation requests:
+ *     - rte_dma_copy()
+ *     - rte_dma_copy_sg()
+ *     - rte_dma_fill()
+ *     - rte_dma_submit()
+ *
+ * These APIs could work with different virtual DMA channels which have
+ * different contexts.
+ *
+ * The first three APIs are used to submit the operation request to the virtual
+ * DMA channel, if the submission is successful, a positive
+ * ring_idx <= UINT16_MAX is returned, otherwise a negative number is returned.
+ *
+ * The last API is used to issue doorbell to hardware, and also there are flags
+ * (@see RTE_DMA_OP_FLAG_SUBMIT) parameter of the first three APIs could do the
+ * same work.
+ * @note When enqueuing a set of jobs to the device, having a separate submit
+ * outside a loop makes for clearer code than having a check for the last
+ * iteration inside the loop to set a special submit flag.  However, for cases
+ * where one item alone is to be submitted or there is a small set of jobs to
+ * be submitted sequentially, having a submit flag provides a lower-overhead
+ * way of doing the submission while still keeping the code clean.
+ *
+ * The second part is to obtain the result of requests:
+ *     - rte_dma_completed()
+ *         - return the number of operation requests completed successfully.
+ *     - rte_dma_completed_status()
+ *         - return the number of operation requests completed.
+ *
+ * @note If the dmadev works in silent mode (@see RTE_DMA_CAPA_SILENT),
+ * application does not invoke the above two completed APIs.
+ *
+ * About the ring_idx which enqueue APIs (e.g. rte_dma_copy(), rte_dma_fill())
+ * return, the rules are as follows:
+ *     - ring_idx for each virtual DMA channel are independent.
+ *     - For a virtual DMA channel, the ring_idx is monotonically incremented,
+ *       when it reach UINT16_MAX, it wraps back to zero.
+ *     - This ring_idx can be used by applications to track per-operation
+ *       metadata in an application-defined circular ring.
+ *     - The initial ring_idx of a virtual DMA channel is zero, after the
+ *       device is stopped, the ring_idx needs to be reset to zero.
+ *
+ * One example:
+ *     - step-1: start one dmadev
+ *     - step-2: enqueue a copy operation, the ring_idx return is 0
+ *     - step-3: enqueue a copy operation again, the ring_idx return is 1
+ *     - ...
+ *     - step-101: stop the dmadev
+ *     - step-102: start the dmadev
+ *     - step-103: enqueue a copy operation, the ring_idx return is 0
+ *     - ...
+ *     - step-x+0: enqueue a fill operation, the ring_idx return is 65535
+ *     - step-x+1: enqueue a copy operation, the ring_idx return is 0
+ *     - ...
+ *
+ * The DMA operation address used in enqueue APIs (i.e. rte_dma_copy(),
+ * rte_dma_copy_sg(), rte_dma_fill()) is defined as rte_iova_t type.
+ *
+ * The dmadev supports two types of address: memory address and device address.
+ *
+ * - memory address: the source and destination address of the memory-to-memory
+ * transfer type, or the source address of the memory-to-device transfer type,
+ * or the destination address of the device-to-memory transfer type.
+ * @note If the device support SVA (@see RTE_DMA_CAPA_SVA), the memory address
+ * can be any VA address, otherwise it must be an IOVA address.
+ *
+ * - device address: the source and destination address of the device-to-device
+ * transfer type, or the source address of the device-to-memory transfer type,
+ * or the destination address of the memory-to-device transfer type.
+ *
  * About MT-safe, all the functions of the dmadev API exported by a PMD are
  * lock-free functions which assume to not be invoked in parallel on different
  * logical cores to work on the same target dmadev object.
