For example,\n+ Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained\n+ from `<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, SSOVF PMD can also be executed using images provided\n+ as part of SDK from Cavium. The SDK includes all the above prerequisites necessary\n+ to bring up a OCTEONTX board.\n+\n+ SDK and related information can be obtained from: `Cavium support site <https://support.cavium.com/>`_.\n+\n+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.\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_MBUF_DEFAULT_MEMPOOL_OPS`` ( set to ``octeontx_fpavf``)\n+\n+ Set default mempool ops to octeontx_fpavf.\n+\n+- ``CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL`` (default ``y``)\n+\n+ Toggle compilation of the ``librte_mempool_octeontx`` driver.\n+\n+- ``CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL_DEBUG`` (default ``n``)\n+\n+ Toggle display of generic debugging messages\n+\n+Driver Compilation\n+~~~~~~~~~~~~~~~~~~\n+\n+To compile the OCTEONTX FPAVF MEMPOOL 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-thunderx-linuxapp-gcc test-build\n+\n+\n+Initialization\n+--------------\n+\n+The octeontx fpavf mempool initialization similar to other mempool\n+drivers like ring. However user need to pass --base-virtaddr as\n+command line input to application example test_mempool.c application.\n+\n+Example:\n+\n+.. code-block:: console\n+\n+ ./build/app/test -c 0xf --socket-mem=1024,0 --base-virtaddr=0x100000000000 --mbuf-pool-ops=\"octeontx_fpavf\" --log-level=8\n", "prefixes": [ "dpdk-dev", "v1", "11/11" ] }
