This is achieved\n+via using the DPCI devices exposed by MC for GPP <--> AIOP interaction.\n+\n+More information can be found at `NXP Official Website\n+<http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-arm-processors:QORIQ-ARM>`_.\n+\n+Features\n+--------\n+\n+The DPAA2 CMDIF implements following features in the rawdev API;\n+\n+- Getting the object ID of the device (DPCI) using attributes\n+- I/O to and from the AIOP device using DPCI\n+\n+Supported DPAA2 SoCs\n+--------------------\n+\n+- LS2084A/LS2044A\n+- LS2088A/LS2048A\n+- LS1088A/LS1048A\n+\n+Prerequisites\n+-------------\n+\n+There are three main pre-requisities for executing DPAA2 CMDIF on a DPAA2\n+compatible board:\n+\n+1. **ARM 64 Tool Chain**\n+\n+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/aarch64-linux-gnu>`_.\n+\n+2. **Linux Kernel**\n+\n+ It can be obtained from `NXP's Github hosting <https://github.com/qoriq-open-source/linux>`_.\n+\n+3. **Rootfile system**\n+\n+ Any *aarch64* supporting filesystem can be used. For example,\n+ Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained\n+ from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_.\n+\n+As an alternative method, DPAA2 CMDIF can also be executed using images provided\n+as part of SDK from NXP. The SDK includes all the above prerequisites necessary\n+to bring up a DPAA2 board.\n+\n+The following dependencies are not part of DPDK and must be installed\n+separately:\n+\n+- **NXP Linux SDK**\n+\n+ NXP Linux software development kit (SDK) includes support for family\n+ of QorIQ® ARM-Architecture-based system on chip (SoC) processors\n+ and corresponding boards.\n+\n+ It includes the Linux board support packages (BSPs) for NXP SoCs,\n+ a fully operational tool chain, kernel and board specific modules.\n+\n+ 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>`_.\n+\n+- **DPDK Extra Scripts**\n+\n+ DPAA2 based resources can be configured easily with the help of ready scripts\n+ as provided in the DPDK Extra repository.\n+\n+ `DPDK Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.\n+\n+Currently supported by DPDK:\n+\n+- NXP SDK **2.0+**.\n+- MC Firmware version **10.0.0** and higher.\n+- Supported architectures: **arm64 LE**.\n+\n+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.\n+\n+.. note::\n+\n+ Some part of fslmc bus code (mc flib - object library) routines are\n+ dual licensed (BSD & GPLv2).\n+\n+Pre-Installation Configuration\n+------------------------------\n+\n+Config File Options\n+~~~~~~~~~~~~~~~~~~~\n+\n+The following options can be modified in the ``config`` file.\n+Please note that enabling debugging options may affect system performance.\n+\n+- ``CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF`` (default ``y``)\n+\n+ Toggle compilation of the ``lrte_pmd_dpaa2_cmdif`` driver.\n+\n+Driver Compilation\n+~~~~~~~~~~~~~~~~~~\n+\n+To compile the DPAA2 CMDIF PMD for Linux arm64 gcc target, run the\n+following ``make`` command:\n+\n+.. code-block:: console\n+\n+ cd <DPDK-source-directory>\n+ make config T=arm64-dpaa2-linuxapp-gcc install\n+\n+Initialization\n+--------------\n+\n+The DPAA2 CMDIF is exposed as a vdev device which consists of dpci devices.\n+On EAL initialization, dpci devices will be probed and then vdev device\n+can be created from the application code by\n+\n+* Invoking ``rte_vdev_init(\"dpaa2_dpci\")`` from the application\n+\n+* Using ``--vdev=\"dpaa2_dpci\"`` in the EAL options, which will call\n+ rte_vdev_init() internally\n+\n+Example:\n+\n+.. code-block:: console\n+\n+ ./your_cmdif_application --vdev=\"dpaa2_dpci\"\n+\n+Limitations\n+-----------\n+\n+Platform Requirement\n+~~~~~~~~~~~~~~~~~~~~\n+\n+DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the\n+``Supported DPAA2 SoCs``.\n", "prefixes": [ "dpdk-dev", "8/9" ] }
