|
|
|
|
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 OCTEON TX FPAVF MEMPOOL PMD for Linux arm64 gcc target, run the
|
|
following ``make`` command:
|
|
|
|
.. code-block:: console
|
|
|
|
cd <DPDK-source-directory>
|
|
make config T=arm64-thunderx-linux-gcc
|
|
|
|
|
|
Initialization
|
|
--------------
|
|
|
|
The OCTEON TX 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"
