parallel or atomic mode. Patch imlmplements Rx queue
configuration and their corresponding callbacks to handle
events from respective queues.

+NXP DPAA Eventdev Driver
+=========================
+
+The dpaa eventdev is an implementation of the eventdev API, that provides a
+wide range of the eventdev features. The eventdev relies on a dpaa based
+platform to perform event scheduling.
+
+More information can be found at `NXP Official Website
+<http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-arm-processors:QORIQ-ARM>`_.
+
+Features
+--------
+
+The DPAA EVENTDEV implements many features in the eventdev API;
+
+- Hardware based event scheduler
+- 4 event ports
+- 4 event queues
+- Parallel flows
+- Atomic flows
+
+Supported DPAA SoCs
+--------------------
+
+- LS1046A
+- LS1043A
+
+Prerequisites
+-------------
+
+There are following pre-requisities for executing EVENTDEV on a DPAA compatible
+platform:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.4-2017.08/aarch64-linux-gnu/>`_.
+
+2. **Linux Kernel**
+
+ It can be obtained from `NXP's Github hosting <https://github.com/qoriq-open-source/linux>`_.
+
+3. **Rootfile system**
+
+ Any *aarch64* supporting filesystem can be used. For example,
+ Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained
+ from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_.
+
+As an alternative method, DPAA EVENTDEV can also be executed using images provided
+as part of SDK from NXP. The SDK includes all the above prerequisites necessary
+to bring up a DPAA board.
+
+The following dependencies are not part of DPDK and must be installed
+separately:
+
+- **NXP Linux SDK**
+
+ NXP Linux software development kit (SDK) includes support for family
+ of QorIQ® ARM-Architecture-based system on chip (SoC) processors
+ and corresponding boards.
+
+ It includes the Linux board support packages (BSPs) for NXP SoCs,
+ a fully operational tool chain, kernel and board specific modules.
+
+ SDK and related information can be obtained from: `NXP QorIQ SDK <http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX>`_.
+
+- **DPDK Extra Scripts**
+
+ DPAA based resources can be configured easily with the help of ready to use
+ xml files as provided in the DPDK Extra repository.
+
+ `DPDK Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.
+
+Currently supported by DPDK:
+
+- NXP SDK **2.0+** or LSDK **17.09+**
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+Please note that enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``librte_pmd_dpaa_event`` driver.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA_EVENTDEV_DEBUG`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA EVENTDEV PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console

+
+Initialization
+--------------
+
+The dpaa eventdev is exposed as a vdev device which consists of a set of channels
+and queues. On EAL initialization, dpaa components will be
+probed and then vdev device can be created from the application code by
+
+* Invoking ``rte_vdev_init("event_dpaa")`` from the application
+
+* Using ``--vdev="event_dpaa"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_eventdev_application --vdev="event_dpaa"
+
+Limitations
+-----------
+
+1. DPAA eventdev can not work with DPAA PUSH mode queues configured for ethdev.
+ Please configure export DPAA_NUM_PUSH_QUEUES=0
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA SoCs``.
+
+Port-core binding
+~~~~~~~~~~~~~~~~~
+
+DPAA EVENTDEV driver requires event port 'x' to be used on core 'x'.
