More information can be found at `Cavium, Inc Official Website `_. Features -------- Features of the OCTEONTX FPAVF PMD are: - 32 SR-IOV Virtual functions - 32 Pools - HW mempool manager Supported OCTEONTX SoCs ----------------------- - CN83xx Prerequisites ------------- See :doc: `../platform/octeontx.rst` for setup information. 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_MBUF_DEFAULT_MEMPOOL_OPS`` ( set to ``octeontx_fpavf``) Set default mempool ops to octeontx_fpavf. - ``CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL`` (default ``y``) Toggle compilation of the ``librte_mempool_octeontx`` driver. Driver Compilation ~~~~~~~~~~~~~~~~~~ To compile the OCTEONTX FPAVF MEMPOOL PMD for Linux arm64 gcc target, run the following ``make`` command: .. code-block:: console cd make config T=arm64-thunderx-linuxapp-gcc test-build Initialization -------------- The octeontx fpavf mempool initialization similar to other mempool drivers like ring. However user need to pass --base-virtaddr as command line input to application example test_mempool.c application. Example: .. code-block:: console ./build/app/test -c 0xf --base-virtaddr=0x100000000000 \ --mbuf-pool-ops-name="octeontx_fpavf"
