The DPCI devices have oth Tx and Rx queues. Event devices use
DPCI Rx queues only, but CMDIF (AIOP) uses both Tx and Rx queues.
This patch enables Tx queues configuration too.

+NXP DPAA2 CMDIF Driver
+======================
+
+The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+communication between the GPP and AIOP (Firmware). This is achieved
+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.
+
+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 DPAA2 CMDIF implements following features in the rawdev API;
+
+- Getting the object ID of the device (DPCI) using attributes
+- I/O to and from the AIOP device using DPCI
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/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, DPAA2 CMDIF 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 DPAA2 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**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ 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+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+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_DPAA2_CMDIF`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Initialization
+--------------
+
+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.
+On EAL initialization, dpci devices will be probed and then vdev device
+can be created from the application code by
+
+* Invoking ``rte_vdev_init("dpaa2_dpci")`` from the application
+
+* Using ``--vdev="dpaa2_dpci"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_cmdif_application --vdev="dpaa2_dpci"
+
+Limitations
+-----------
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

I think you should put one more new line here. For all the sub-section

If already added in armv8a, why is it required in arm64-dpaa2 as well?
Rawdevices are intended to be custom and I think they should be added
only to the SoC specific configuration files.

Please move this change to common config.
We already agreed that you guys move the changes to common config in
this release.
I would like to avoid any compilation errors specific only to arm64
such as this

As I understand you suggest this to be part of only arm64-dpaa2 and not in armv8a?

The DPCI devices have oth Tx and Rx queues. Event devices use
DPCI Rx queues only, but CMDIF (AIOP) uses both Tx and Rx queues.
This patch enables Tx queues configuration too.

+NXP DPAA2 CMDIF Driver
+======================
+
+The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+communication between the GPP and AIOP (Firmware). This is achieved
+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.
+
+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 DPAA2 CMDIF implements following features in the rawdev API;
+
+- Getting the object ID of the device (DPCI) using attributes
+- I/O to and from the AIOP device using DPCI
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/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, DPAA2 CMDIF 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 DPAA2 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**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ 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+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Initialization
+--------------
+
+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.
+On EAL initialization, dpci devices will be probed and then vdev device
+can be created from the application code by
+
+* Invoking ``rte_vdev_init("dpaa2_dpci")`` from the application
+
+* Using ``--vdev="dpaa2_dpci"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_cmdif_application --vdev="dpaa2_dpci"
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

You need to remove the .rst extension from above for it to be a clickable and linked to the html version of the file.
Once it's done you can add my ack to the second version.

Just like the QDMA series, you might want to remove 'rst' from the above.

This patch set introduces DPAA2 based Command Interface
device driver.
This driver is provides communication between the GPP and
AIOP Firmware.
This patchset is based on top of:
https://dpdk.org/dev/patchwork/patch/38798/
Patches 1-3:
Makes necessary changes and fixes in the DPAA2 bus and
mempool region
Patches 4-6:
Add the DPAA2 CMDIF driver
Patches 7:
Update the respective documentation
Changes in v2:
- Move CMDIF compilation to common_linuxapp
- Support physical addressing mode
Changes in v3:
- Rebased over DPAA2 QDMA patches
- Updated logging adding Data Path logs too
- Fix up error handling in patch 3
- Merged the two separate doc patches (patch 7)
Nipun Gupta (7):
mempool/dpaa2: add functions exposed to DPDK applications
bus/fslmc: expose API to free dpci device
bus/fslmc: keep Tx queues information for DPCI devices too
raw/dpaa2_cmdif: introduce DPAA2 command interface driver
raw/dpaa2_cmdif: add attribute get functionality
raw/dpaa2_cmdif: support enqueue dequeue operations

There are two API's which are required by NXP specific Command Interface
Application (AIOP CMDIF). This patch exposes these two API's.

The DPCI devices have oth Tx and Rx queues. Event devices use
DPCI Rx queues only, but CMDIF (AIOP) uses both Tx and Rx queues.
This patch enables Tx queues configuration too.

+NXP DPAA2 CMDIF Driver
+======================
+
+The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+communication between the GPP and AIOP (Firmware). This is achieved
+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.
+
+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 DPAA2 CMDIF implements following features in the rawdev API;
+
+- Getting the object ID of the device (DPCI) using attributes
+- I/O to and from the AIOP device using DPCI
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/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, DPAA2 CMDIF 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 DPAA2 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**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ 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+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF_RAWDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Initialization
+--------------
+
+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.
+On EAL initialization, dpci devices will be probed and then vdev device
+can be created from the application code by
+
+* Invoking ``rte_vdev_init("dpaa2_dpci")`` from the application
+
+* Using ``--vdev="dpaa2_dpci"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_cmdif_application --vdev="dpaa2_dpci"
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

DPCI Rx queues only, but CMDIF (AIOP) uses both Tx and Rx queues.
This patch enables Tx queues configuration too.

+NXP DPAA2 CMDIF Driver
+======================
+
+The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+communication between the GPP and AIOP (Firmware). This is achieved
+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.
+
+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 DPAA2 CMDIF implements following features in the rawdev API;
+
+- Getting the object ID of the device (DPCI) using attributes
+- I/O to and from the AIOP device using DPCI
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/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, DPAA2 CMDIF 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 DPAA2 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**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ 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+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF_RAWDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+ ./your_cmdif_application <EAL args> --log-level=pmd.raw.dpaa2.cmdif,<level>
+
+Using ``pmd.raw.dpaa2.cmdif`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Initialization
+--------------
+
+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.
+On EAL initialization, dpci devices will be probed and then vdev device
+can be created from the application code by
+
+* Invoking ``rte_vdev_init("dpaa2_dpci")`` from the application
+
+* Using ``--vdev="dpaa2_dpci"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_cmdif_application <EAL args> --vdev="dpaa2_dpci"
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

Nipun,
Above doxygen change is appearing under 'device-specific' with 'dpaa2'
as tag. I think it should be 'dpaa2_mempool'.

There are two API's which are required by NXP specific Command Interface
Application (AIOP CMDIF). This patch exposes these two API's.

+NXP DPAA2 CMDIF Driver
+======================
+
+The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+communication between the GPP and AIOP (Firmware). This is achieved
+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.
+
+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 DPAA2 CMDIF implements following features in the rawdev API;
+
+- Getting the object ID of the device (DPCI) using attributes
+- I/O to and from the AIOP device using DPCI
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/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, DPAA2 CMDIF 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 DPAA2 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**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ 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+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF_RAWDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+ ./your_cmdif_application <EAL args> --log-level=pmd.raw.dpaa2.cmdif,<level>
+
+Using ``pmd.raw.dpaa2.cmdif`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Initialization
+--------------
+
+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.
+On EAL initialization, dpci devices will be probed and then vdev device
+can be created from the application code by
+
+* Invoking ``rte_vdev_init("dpaa2_dpci")`` from the application
+
+* Using ``--vdev="dpaa2_dpci"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_cmdif_application <EAL args> --vdev="dpaa2_dpci"
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

+NXP DPAA2 CMDIF Driver
+======================
+
+The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+communication between the GPP and AIOP (Firmware). This is achieved
+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.
+
+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 DPAA2 CMDIF implements following features in the rawdev API;
+
+- Getting the object ID of the device (DPCI) using attributes
+- I/O to and from the AIOP device using DPCI
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/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, DPAA2 CMDIF 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 DPAA2 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**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ 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+**.
+- MC Firmware version **10.0.0** and higher.
+- Supported architectures: **arm64 LE**.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+.. note::
+
+ Some part of fslmc bus code (mc flib - object library) routines are
+ dual licensed (BSD & GPLv2).
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF_RAWDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+ ./your_cmdif_application <EAL args> --log-level=pmd.raw.dpaa2.cmdif,<level>
+
+Using ``pmd.raw.dpaa2.cmdif`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+ cd <DPDK-source-directory>
+ make config T=arm64-dpaa2-linuxapp-gcc install
+
+Initialization
+--------------
+
+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.
+On EAL initialization, dpci devices will be probed and then vdev device
+can be created from the application code by
+
+* Invoking ``rte_vdev_init("dpaa2_dpci")`` from the application
+
+* Using ``--vdev="dpaa2_dpci"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_cmdif_application <EAL args> --vdev="dpaa2_dpci"
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
