  33 Pre-Installation Configuration
  34 ------------------------------
  35
  36 Config File Options
  37 ~~~~~~~~~~~~~~~~~~~
  38
  39 The following options can be modified in the ``config`` file.
  40 Please note that enabling debugging options may affect system performance.
  41
  42 - ``CONFIG_RTE_MBUF_DEFAULT_MEMPOOL_OPS`` ( set to ``octeontx_fpavf``)
  43
  44   Set default mempool ops to octeontx_fpavf.
  45
  46 - ``CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL`` (default ``y``)
  47
  48   Toggle compilation of the ``librte_mempool_octeontx`` driver.
  49
  50 Driver Compilation
  51 ~~~~~~~~~~~~~~~~~~
  52
  53 To compile the OCTEONTX FPAVF MEMPOOL PMD for Linux arm64 gcc target, run the
  54 following ``make`` command:
  55
  56 .. code-block:: console
  57
  58    cd <DPDK-source-directory>
  59    make config T=arm64-thunderx-linuxapp-gcc test-build

  61
  62 Initialization
  63 --------------
  64
  65 The octeontx fpavf mempool initialization similar to other mempool
  66 drivers like ring. However user need to pass --base-virtaddr as
  67 command line input to application example test_mempool.c application.
  68
  69 Example:
  70
  71 .. code-block:: console
  72
  73     ./build/app/test -c 0xf --base-virtaddr=0x100000000000 \
  74                         --mbuf-pool-ops-name="octeontx_fpavf"
