+DMA Device Library
+====================
+
+The DMA library provides a DMA device framework for management and provisioning
+of hardware and software DMA poll mode drivers, defining generic APIs which
+support a number of different DMA operations.
+
+
+Design Principles
+-----------------
+
+The DMA library follows the same basic principles as those used in DPDK's
+Ethernet Device framework and the RegEx framework. The DMA framework provides
+a generic DMA device framework which supports both physical (hardware)
+and virtual (software) DMA devices as well as a generic DMA API which allows
+DMA devices to be managed and configured and supports DMA operations to be
+provisioned on DMA poll mode driver.
+
+.. _figure_dmadev_i1:
+
+.. figure:: img/dmadev_i1.*
+
+   The model of the DMA framework built on
+
+ * The DMA controller could have multiple hardware DMA channels (aka. hardware
+   DMA queues), each hardware DMA channel should be represented by a dmadev.
+ * The dmadev could create multiple virtual DMA channels, each virtual DMA
+   channel represents a different transfer context. The DMA operation request
+   must be submitted to the virtual DMA channel. e.g. Application could create
+   virtual DMA channel 0 for memory-to-memory transfer scenario, and create
+   virtual DMA channel 1 for memory-to-device transfer scenario.
+
+
+Device Management
+-----------------
+
+Device Creation
+~~~~~~~~~~~~~~~
+
+Physical DMA controller is discovered during the PCI probe/enumeration of the
+EAL function which is executed at DPDK initialization, based on their PCI
+device identifier, each unique PCI BDF (bus/bridge, device, function). Specific
+physical DMA controller, like other physical devices in DPDK can be listed using
+the EAL command line options.
+
+And then dmadevs are dynamically allocated by rte_dmadev_pmd_allocate() based on
+the number of hardware DMA channels.
+
+
+Device Identification
+~~~~~~~~~~~~~~~~~~~~~
+
+Each DMA device, whether physical or virtual is uniquely designated by two
+identifiers:
+
+- A unique device index used to designate the DMA device in all functions
+  exported by the DMA API.
+
+- A device name used to designate the DMA device in console messages, for
+  administration or debugging purposes.
+
+
+Device Configuration
+~~~~~~~~~~~~~~~~~~~~
+
+The rte_dmadev_configure API is used to configure a DMA device.
+
+.. code-block:: c
+
+   int rte_dmadev_configure(uint16_t dev_id,
+                            const struct rte_dmadev_conf *dev_conf);
+
+The ``rte_dmadev_conf`` structure is used to pass the configuration parameters
+for the DMA device for example maximum number of virtual DMA channels,
+indication of whether to enable silent mode.
+
+
+Configuration of Virtual DMA Channels
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The rte_dmadev_vchan_setup API is used to configure a virtual DMA channel.
+
+.. code-block:: c
+
+   int rte_dmadev_vchan_setup(uint16_t dev_id,
+		                      const struct rte_dmadev_vchan_conf *conf);
+
+The ``rte_dmadev_vchan_conf`` structure is used to pass the configuration
+parameters for the virtual DMA channel for example transfer direction, number of
+descriptor for the virtual DMA channel, source device access port parameter,
+destination device access port parameter.
+
+
+Device Features and Capabilities
+--------------------------------
+
+DMA devices may support different feature set. In order to get the supported PMD
+features ``rte_dmadev_info_get`` API which returns the info of the device and
+it's supported features.
+
+A special device capability is silent mode which application don't required to
+invoke dequeue APIs.
+
+
+Enqueue / Dequeue APIs
+~~~~~~~~~~~~~~~~~~~~~~
+
+The enqueue APIs include like ``rte_dmadev_copy`` and ``rte_dmadev_fill``, if
+enqueue successful, an uint16_t 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_dmadev_submit`` API was used to issue doorbell to hardware, and also
+there are flags (``RTE_DMA_OP_FLAG_SUBMIT``) parameter of the enqueue APIs
+could do the same work.
+
+There are two dequeue APIs (``rte_dmadev_completed`` and
+``rte_dmadev_completed_status``) could used to obtain the result of request.
+The first API returns the number of operation requests completed successfully,
+the second API returns the number of operation requests completed which may
+successfully or failed and also with meaningful status code. Also these two
+APIs could return the last completed operation's ring_idx which will help to
+track application-defined circular ring.
