OCTEON TX FPAVF Mempool Driver
==============================
The OCTEON TX FPAVF PMD (**librte_mempool_octeontx**) is a mempool
driver for offload mempool device found in **Cavium OCTEON TX** SoC
family.
More information can be found at `Cavium, Inc Official Website
<http://www.cavium.com/OCTEON-TX_ARM_Processors.html>`_.
Features
--------
Features of the OCTEON TX FPAVF PMD are:
- 32 SR-IOV Virtual functions
- 32 Pools
- HW mempool manager
Supported OCTEON TX 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 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-linuxapp-gcc test-build
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"
