+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 API which
+support a number of different DMA operations.
+
+
+Design Principles
+-----------------
+
+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:
+
+.. figure:: img/dmadev.*
+
+The above figure shows the model on which the DMA framework is 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 controllers are discovered during the PCI probe/enumeration of the
+EAL function which is executed at DPDK initialization, this is based on their
+PCI BDF (bus/bridge, device, function). Specific physical DMA controllers, like
+other physical devices in DPDK can be listed using the EAL command line options.
+
+The dmadevs are dynamically allocated by using the function
+``rte_dma_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.

+ *
+ * The DMA controller could have multiple HW-DMA-channels (aka. HW-DMA-queues),
+ * each HW-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.
+ *
+ * This framework uses 'int16_t dev_id' as the device identifier of a dmadev,
+ * and 'uint16_t vchan' as the virtual DMA channel identifier in one dmadev.
