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_LIBRTE_OCTEONTX_PMD`` (default ``y``)
-
- Toggle compilation of the ``librte_pmd_octeontx`` driver.
Driver compilation and testing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
for details.
-To compile the OCTEON TX 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 install
-
#. Running testpmd:
Follow instructions available in the document
.. code-block:: console
- ./arm64-thunderx-linux-gcc/app/testpmd -c 700 \
+ ./<build_dir>/app/dpdk-testpmd -c 700 \
--base-virtaddr=0x100000000000 \
--mbuf-pool-ops-name="octeontx_fpavf" \
--vdev='event_octeontx' \
is fixed and cannot be changed. So, even when the ``rxmode.max_rx_pkt_len``
member of ``struct rte_eth_conf`` is set to a value lower than 32k, frames
up to 32k bytes can still reach the host interface.
+
+Maximum mempool size
+~~~~~~~~~~~~~~~~~~~~
+
+The maximum mempool size supplied to Rx queue setup should be less than 128K.
+When running testpmd on OCTEON TX the application can limit the number of mbufs
+by using the option ``--total-num-mbufs=131072``.
