[dpdk-dev] [PATCH 0/8] Introduce DPAA2 QDMA raw driver

[Nipun Gupta]

This patch set introduces DPAA2 based QDMA device driver.

It provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction.

This patch series is based over v2 of DPAA2 CMDIF series -
https://dpdk.org/dev/patchwork/patch/35337/

Patches 1-3:
  Makes necessary changes in the DPAA2 bus
Patches 4-6:
  Add the DPAA2 QDMA driver
Patches 7-8:
  Update the respective documentation

Nipun Gupta (8):
  bus/fslmc: support MC DPDMAI object
  bus/fslmc: support scanning and probing of QDMA devices
  bus/fslmc: add macros required by QDMA for FLE and FD
  raw/dpaa2_qdma: introduce the DPAA2 QDMA driver
  raw/dpaa2_qdma: support configuration APIs
  raw/dpaa2_qdma: support enq and deq operations

I think the definition of DPAA2_QDMA_ERR also contains an inbuilt '\n' - 
so, it would be double new lines. And this is valid at various other 
places in this patch.

I think you might want to revisit this. TAILQ_FIRST will keep returning 
you the head of the list. TAILQ_FOREACH_SAFE is what you should be 
looking at.

Should dpdmai_close be called here? In case there is some state managed 
in the device which might impact its opening next time.
This would be valid for various errors generated in this function.

It is better to not add a new line here - that we we can relate the 
function below with the INIT macro above.

The string for registeration should be of format 
'pmd.raw.<driver>.<feature>'.
See SHA: 7db274b9ada2221acb7110204a3b2c6a37d2614a for documentation.

Some logs don't need to have a function name associated with them in 
output - especially the error messages. All the macros here have 
'__func__'  as part of the output. Can you rethink if this is OK with you?

This shouldn't be placed between the bus linking instructions. Maybe 
somewhere near the other rawdev PMD would be better.

Similar comment to one of the other patch - your macro definition has 
'\n' already in it. So, double new lines.

Macros like the above are compiled into the code unlike the DP_ 
variants. If this is I/O path and such conditionals impact performance, 
maybe DP_ variant would be more efficient.

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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_QDMA`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.dpaa2.qdma,<level>
+
+Using ``dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

You will have to change/confirm the log-level string above. There is a 
comment on one of the patch defining this string.

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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_QDMA`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

Re: [dpdk-dev] [PATCH 0/9 v2] Introduce DPAA2 QDMA raw driver

[Nipun Gupta]

Hi Shreyansh,

I have taken care of all your comments from the v1 series as all were appropriate :)

Also I have rebased on master branch and will rebase CMDIF series over this one.
This lead to addition of patch 4 and some more changes in patch 3 here. Please re-review these.

Thanks,
Nipun

Re: [dpdk-dev] [PATCH 0/9 v2] Introduce DPAA2 QDMA raw driver

[Nipun Gupta]

There is a compilation issue due to a recent change on master branch
http://dpdk.org/browse/dpdk/commit/?id=3ef648aa4854f53b5ad3f148dc021852157a0246

I am sending a v3 fixing the compilation issue.

[Nipun Gupta]

This patch set introduces DPAA2 based QDMA device driver.

It provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction.

This patch series is rebased on dpdk master branch

Patches 1-4:
  Makes necessary changes in the DPAA2 bus
Patches 5-7:
  Add the DPAA2 QDMA driver
Patches 8-9:
  Update the respective documentation

Changes in v2:
  - Rebased over master branch
  - Pulled in couple of changes which were in CMDIF series
    - patch 3: some updations, patch 4
  - handle failues in device init correctly
  - Updated the logging, added DP logs
  - Fixed remove_hw_queues_from_list function

Changes in v3:
  - Fix compilation issue introduced due to a very recent change
    of removal of dma_addr_t. Fix in patch 7 where dma_addr_t
    was used.

Nipun Gupta (9):
  bus/fslmc: support MC DPDMAI object
  bus/fslmc: support scanning and probing of QDMA devices
  bus/fslmc: add macros required by QDMA for FLE and FD
  bus/fslmc: fix typecasting in IOVA/virt conversion macros
  raw/dpaa2_qdma: introduce the DPAA2 QDMA driver
  raw/dpaa2_qdma: support configuration APIs
  raw/dpaa2_qdma: support enq and deq operations
  doc: add DPAA2 QDMA rawdev guide
  doc: add dpaa2 qdma rawdev to release notes

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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 **10.3.0** 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_QDMA`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

I think you must remove the .rst extension.

1/ Please compile this driver with meson.

2/ I think you should declare the new API functions as experimental.

3/ This series won't be in RC1, but is candidate for RC2. Is it OK?

[dpdk-dev] [PATCH 0/8 v4] Introduce DPAA2 QDMA raw driver

[Nipun Gupta]

This patch set introduces DPAA2 based QDMA device driver.

It provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction.

This patch series is rebased on dpdk master branch

Patch 1:
  Support meson build in raw
Patches 2-4:
  Makes necessary changes in the DPAA2 bus
Patches 5-7:
  Add the DPAA2 QDMA driver
Patch 8:
  Update the documentation

Changes in v2:
  - Rebased over master branch
  - Pulled in couple of changes which were in CMDIF series
    - patch 3: some updations, patch 4
  - handle failues in device init correctly
  - Updated the logging, added DP logs
  - Fixed remove_hw_queues_from_list function

Changes in v3:
  - Fix compilation issue introduced due to a very recent change
    of removal of dma_addr_t. Fix in patch 7 where dma_addr_t
    was used.

Changes in v4:
  - Support meson build for raw and dpaa2 qdma (patch 1 & 5)
  - Merged the two separate doc patches (patch 8)

Nipun Gupta (8):
  raw: support meson build
  bus/fslmc: support MC DPDMAI object
  bus/fslmc: support scanning and probing of QDMA devices
  bus/fslmc: add macros required by QDMA for FLE and FD
  raw/dpaa2_qdma: introduce the DPAA2 QDMA driver
  raw/dpaa2_qdma: support configuration APIs
  raw/dpaa2_qdma: support enq and deq operations
  doc: add DPAA2 QDMA rawdev guide

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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 LSDK **17.12+**.
+- MC Firmware version **10.3.0** 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_QDMA_RAWDEV`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

[dpdk-dev] [PATCH v5 0/8] Introduce DPAA2 QDMA raw driver

[Nipun Gupta]

This patch set introduces DPAA2 based QDMA device driver.

It provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction.

This patch series is rebased on dpdk master branch

Patch 1:
  Support meson build in raw
Patches 2-4:
  Makes necessary changes in the DPAA2 bus
Patches 5-7:
  Add the DPAA2 QDMA driver
Patch 8:
  Update the documentation

Changes in v2:
  - Rebased over master branch
  - Pulled in couple of changes which were in CMDIF series
    - patch 3: some updations, patch 4
  - handle failues in device init correctly
  - Updated the logging, added DP logs
  - Fixed remove_hw_queues_from_list function

Changes in v3:
  - Fix compilation issue introduced due to a very recent change
    of removal of dma_addr_t. Fix in patch 7 where dma_addr_t
    was used.

Changes in v4:
  - Support meson build for raw and dpaa2 qdma (patch 1 & 5)
  - Merged the two separate doc patches (patch 8)

Changes in v5:
  - install user header file (rte_pmd_dpaa2_qdma.h) in case of
    meson build where it is introduced (patch 6). Previously
    it was added in patch 5.

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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 Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.
+
+Currently supported by DPDK:
+
+- NXP LSDK **17.12+**.
+- MC Firmware version **10.3.0** 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_QDMA_RAWDEV`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

[dpdk-dev] [PATCH v6 0/8] Introduce DPAA2 QDMA raw driver

[Nipun Gupta]

This patch set introduces DPAA2 based QDMA device driver.

It provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction.

This patch series is rebased on dpdk master branch

Patch 1:
  Support meson build in raw
Patches 2-4:
  Makes necessary changes in the DPAA2 bus
Patches 5-7:
  Add the DPAA2 QDMA driver
Patch 8:
  Update the documentation

Changes in v2:
  - Rebased over master branch
  - Pulled in couple of changes which were in CMDIF series
    - patch 3: some updations, patch 4
  - handle failues in device init correctly
  - Updated the logging, added DP logs
  - Fixed remove_hw_queues_from_list function

Changes in v3:
  - Fix compilation issue introduced due to a very recent change
    of removal of dma_addr_t. Fix in patch 7 where dma_addr_t
    was used.

Changes in v4:
  - Support meson build for raw and dpaa2 qdma (patch 1 & 5)
  - Merged the two separate doc patches (patch 8)

Changes in v5:
  - install user header file (rte_pmd_dpaa2_qdma.h) in case of
    meson build where it is introduced (patch 6). Previously
    it was added in patch 5.

Changes in v6:
  - Fix meson shared build

Nipun Gupta (8):
  raw: support meson build
  bus/fslmc: support MC DPDMAI object
  bus/fslmc: support scanning and probing of QDMA devices
  bus/fslmc: add macros required by QDMA for FLE and FD
  raw/dpaa2_qdma: introduce the DPAA2 QDMA driver
  raw/dpaa2_qdma: support configuration APIs
  raw/dpaa2_qdma: support enq and deq operations
  doc: add DPAA2 QDMA rawdev guide

[dpdk-dev] [PATCH v6 5/8] raw/dpaa2_qdma: introduce the DPAA2 QDMA driver

[Nipun Gupta]

DPAA2 QDMA driver uses MC DPDMAI object. This driver enables
the user (app) to perform data DMA without involving CPU in
the DMA process

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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 LSDK **17.12+**.
+- MC Firmware version **10.3.0** 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_QDMA_RAWDEV`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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 LSDK **17.12+**.
+- MC Firmware version **10.3.0** 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).

+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_QDMA_RAWDEV`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.

Patch 1:
  Support meson build in raw
Patches 2-4:
  Makes necessary changes in the DPAA2 bus
Patches 5-7:
  Add the DPAA2 QDMA driver
Patch 8:
  Update the documentation

Changes in v2:
  - Rebased over master branch
  - Pulled in couple of changes which were in CMDIF series
    - patch 3: some updations, patch 4
  - handle failues in device init correctly
  - Updated the logging, added DP logs
  - Fixed remove_hw_queues_from_list function

Changes in v3:
  - Fix compilation issue introduced due to a very recent change
    of removal of dma_addr_t. Fix in patch 7 where dma_addr_t
    was used.

Changes in v4:
  - Support meson build for raw and dpaa2 qdma (patch 1 & 5)
  - Merged the two separate doc patches (patch 8)

Changes in v5:
  - install user header file (rte_pmd_dpaa2_qdma.h) in case of
    meson build where it is introduced (patch 6). Previously
    it was added in patch 5.

Changes in v6:
  - Fix meson shared build

Changes in v7:
  - Fix x86 shared build

Nipun Gupta (8):
  raw: support meson build
  bus/fslmc: support MC DPDMAI object
  bus/fslmc: support scanning and probing of QDMA devices
  bus/fslmc: add macros required by QDMA for FLE and FD
  raw/dpaa2_qdma: introduce the DPAA2 QDMA driver
  raw/dpaa2_qdma: support configuration APIs
  raw/dpaa2_qdma: support enq and deq operations
  doc: add DPAA2 QDMA rawdev guide

+NXP DPAA2 QDMA Driver
+=====================
+
+The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+to initiate a DMA transaction from CPU. The initiated DMA is performed
+without CPU being involved in the actual DMA transaction. This is achieved
+via using the DPDMAI device exposed by MC.
+
+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 QDMA implements following features in the rawdev API;
+
+- Supports issuing DMA of data within memory without hogging CPU while
+  performing DMA operation.
+- Supports configuring to optionally get status of the DMA translation on
+  per DMA operation basis.
+
+Supported DPAA2 SoCs
+--------------------
+
+- LS2084A/LS2044A
+- LS2088A/LS2048A
+- LS1088A/LS1048A
+
+Prerequisites
+-------------
+
+There are three main pre-requisities for executing DPAA2 QDMA 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 QDMA 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 LSDK **17.12+**.
+- MC Firmware version **10.3.0** 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_QDMA_RAWDEV`` (default ``y``)
+
+  Toggle compilation of the ``lrte_pmd_dpaa2_qdma`` driver.
+
+Enabling logs
+-------------
+
+For enabling logs, use the following EAL parameter:
+
+.. code-block:: console
+
+   ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
+
+Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can be
+enabled which are lower than logging ``level``.
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the DPAA2 QDMA 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 QDMA is exposed as a vdev device which consists of dpdmai devices.
+On EAL initialization, dpdmai devices will be probed and populated into the
+rawdevices. The rawdev ID of the device can be obtained using
+
+* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
+  where x is the object ID of the DPDMAI object created by MC. Use can
+  use this index for further rawdev function calls.
+
+Platform Requirement
+~~~~~~~~~~~~~~~~~~~~
+
+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
+``Supported DPAA2 SoCs``.
