There are muliple help mc object, which are not an independent
device, but they are required for dpaa2 based devices.
This framework allows registration and handling of all such
mc devices.

This patch removes the existing static call for dpio and dpbp
create and add them to object registration framework.
This patch also changes the vfio mc object processing to use

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.

qbman_get_dqrr_idx() API is required with constant dqrr entry
in the eventdev driver. Also, this routine is not updating the
dqrr. So, this patch updates its input argument to a const type.

+
+NXP DPAA2 Eventdev Driver
+==================================
+
+The dpaa2 eventdev is an implementation of the eventdev API, that provides a
+wide range of the eventdev features. The eventdev relies on a dpaa2 hw 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 DPAA2 EVENTDEV implements many features in the eventdev API;
+
+- Hardware based event scheduler
+- 8 event ports
+- 8 event queues
+- Parallel flows
+- Atomic flows
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2080A/LS2040A
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 EVENTDEV on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/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 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 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 Helper Scripts**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ as provided in the DPDK helper repository.
+
+ `DPDK Helper Scripts <https://github.com/qoriq-open-source/dpdk-helper>`_.
+
+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_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_event`` driver.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV_DEBUG`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 EVENTDEV 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 eventdev is exposed as a vdev device which consists of a set of dpcon
+devices and dpci devices. On EAL initialization, dpcon and dpci devices will be
+probed and then vdev device can be created from the application code by
+
+* Invoking ``rte_vdev_init("event_dpaa2")`` from the application
+
+* Using ``--vdev="event_dpaa2"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_eventdev_application --vdev="event_dpaa2"
+
+Limitations
+-----------
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
+
+Port-core binding
+~~~~~~~~~~~~~~~~~
+
+DPAA2 EVENTDEV driver requires event port 'x' to be used on core 'x'.

Hi Jerin,
Is there anything pending for this patch series to be merged?
Do you want me to rebase it on the dpdk main repository as dpdk-next-eventdev branch is not currently in sync with main repo?
Regards,
Nipun

There are muliple help mc object, which are not an independent
device, but they are required for dpaa2 based devices.
This framework allows registration and handling of all such
mc devices.

This patch removes the existing static call for dpio and dpbp
create and add them to object registration framework.
This patch also changes the vfio mc object processing to use
the framework.

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.

qbman_get_dqrr_idx() API is required with constant dqrr entry
in the eventdev driver. Also, this routine is not updating the
dqrr. So, this patch updates its input argument to a const type.

+
+NXP DPAA2 Eventdev Driver
+==================================
+
+The dpaa2 eventdev is an implementation of the eventdev API, that provides a
+wide range of the eventdev features. The eventdev relies on a dpaa2 hw 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 DPAA2 EVENTDEV implements many features in the eventdev API;
+
+- Hardware based event scheduler
+- 8 event ports
+- 8 event queues
+- Parallel flows
+- Atomic flows
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2080A/LS2040A
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 EVENTDEV on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/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 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 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 Helper Scripts**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ as provided in the DPDK helper repository.
+
+ `DPDK Helper Scripts <https://github.com/qoriq-open-source/dpdk-helper>`_.
+
+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_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_event`` driver.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV_DEBUG`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 EVENTDEV 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 eventdev is exposed as a vdev device which consists of a set of dpcon
+devices and dpci devices. On EAL initialization, dpcon and dpci devices will be
+probed and then vdev device can be created from the application code by
+
+* Invoking ``rte_vdev_init("event_dpaa2")`` from the application
+
+* Using ``--vdev="event_dpaa2"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_eventdev_application --vdev="event_dpaa2"
+
+Limitations
+-----------
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
+
+Port-core binding
+~~~~~~~~~~~~~~~~~
+
+DPAA2 EVENTDEV driver requires event port 'x' to be used on core 'x'.

There are muliple help mc object, which are not an independent

This framework allows registration and handling of all such
mc devices.

This patch removes the existing static call for dpio and dpbp
create and add them to object registration framework.
This patch also changes the vfio mc object processing to use
the framework.

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.

qbman_get_dqrr_idx() API is required with constant dqrr entry
in the eventdev driver. Also, this routine is not updating the
dqrr. So, this patch updates its input argument to a const type.

+
+NXP DPAA2 Eventdev Driver
+==================================
+
+The dpaa2 eventdev is an implementation of the eventdev API, that provides a
+wide range of the eventdev features. The eventdev relies on a dpaa2 hw 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 DPAA2 EVENTDEV implements many features in the eventdev API;
+
+- Hardware based event scheduler
+- 8 event ports
+- 8 event queues
+- Parallel flows
+- Atomic flows
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2080A/LS2040A
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 EVENTDEV on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/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 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 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 Helper Scripts**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ as provided in the DPDK helper repository.
+
+ `DPDK Helper Scripts <https://github.com/qoriq-open-source/dpdk-helper>`_.
+
+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_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_event`` driver.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV_DEBUG`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 EVENTDEV 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 eventdev is exposed as a vdev device which consists of a set of dpcon
+devices and dpci devices. On EAL initialization, dpcon and dpci devices will be
+probed and then vdev device can be created from the application code by
+
+* Invoking ``rte_vdev_init("event_dpaa2")`` from the application
+
+* Using ``--vdev="event_dpaa2"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_eventdev_application --vdev="event_dpaa2"
+
+Limitations
+-----------
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
+
+Port-core binding
+~~~~~~~~~~~~~~~~~
+
+DPAA2 EVENTDEV driver requires event port 'x' to be used on core 'x'.

Overall it looks good.
There are a few check-git log and check-patch errors. Please send the
next version with fixes that makes sense.
If there are no more review comments. I will pull the next version in a week for
eventdev-next.

There are muliple help mc object, which are not an independent
device, but they are required for dpaa2 based devices.
This framework allows registration and handling of all such
mc devices.

This patch removes the existing static call for dpio and dpbp
create and add them to object registration framework.
This patch also changes the vfio mc object processing to use
the framework.

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.

qbman_get_dqrr_idx() API is required with constant dqrr entry
in the eventdev driver. Also, this routine is not updating the
dqrr. So, this patch updates its input argument to a const type.

+
+NXP DPAA2 Eventdev Driver
+==================================
+
+The dpaa2 eventdev is an implementation of the eventdev API, that provides a
+wide range of the eventdev features. The eventdev relies on a dpaa2 hw 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 DPAA2 EVENTDEV implements many features in the eventdev API;
+
+- Hardware based event scheduler
+- 8 event ports
+- 8 event queues
+- Parallel flows
+- Atomic flows
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2080A/LS2040A
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 EVENTDEV on a DPAA2
+compatible board:
+
+1. **ARM 64 Tool Chain**
+
+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/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 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 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 Helper Scripts**
+
+ DPAA2 based resources can be configured easily with the help of ready scripts
+ as provided in the DPDK helper repository.
+
+ `DPDK Helper Scripts <https://github.com/qoriq-open-source/dpdk-helper>`_.
+
+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_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``lrte_pmd_dpaa2_event`` driver.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV_DEBUG`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 EVENTDEV 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 eventdev is exposed as a vdev device which consists of a set of dpcon
+devices and dpci devices. On EAL initialization, dpcon and dpci devices will be
+probed and then vdev device can be created from the application code by
+
+* Invoking ``rte_vdev_init("event_dpaa2")`` from the application
+
+* Using ``--vdev="event_dpaa2"`` in the EAL options, which will call
+ rte_vdev_init() internally
+
+Example:
+
+.. code-block:: console
+
+ ./your_eventdev_application --vdev="event_dpaa2"
+
+Limitations
+-----------
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
+
+Port-core binding
+~~~~~~~~~~~~~~~~~
+
+DPAA2 EVENTDEV driver requires event port 'x' to be used on core 'x'.

Now that this drivers got merged to next-eventdev. I think, The
inclusion of this driver can be added release notes. If you think so then
send a patch to update the release notes.
