The OCTEON TX2 crypto PMD may be compiled natively on an OCTEON TX2 platform or
cross-compiled on an x86 platform.
-Enable OCTEON TX2 crypto PMD in your config file:
-
-* ``CONFIG_RTE_LIBRTE_PMD_OCTEONTX2_CRYPTO=y``
-
Refer to :doc:`../platform/octeontx2` for instructions to build your DPDK
application.
.. note::
- Ensure that sufficient huge pages are available for your application::
+ * For CN98xx SoC, it is recommended to use even and odd DBDF VFs to achieve
+ higher performance as even VF uses one crypto engine and odd one uses
+ another crypto engine.
- echo 8 > /sys/kernel/mm/hugepages/hugepages-524288kB/nr_hugepages
+ * Ensure that sufficient huge pages are available for your application::

Debugging Options
-----------------
.. code-block:: console
- ./test
+ ./dpdk-test
RTE>>cryptodev_octeontx2_autotest
The asymmetric crypto operations on OCTEON TX2 crypto PMD may be verified by running the test
.. code-block:: console

+
+Lookaside IPsec Support
+-----------------------
+
+The OCTEON TX2 SoC can accelerate IPsec traffic in lookaside protocol mode,
+with its **cryptographic accelerator (CPT)**. ``OCTEON TX2 crypto PMD`` implements
+this as an ``RTE_SECURITY_ACTION_TYPE_LOOKASIDE_PROTOCOL`` offload.
+
+Refer to :doc:`../prog_guide/rte_security` for more details on protocol offloads.
+
+This feature can be tested with ipsec-secgw sample application.

+Limitations
+-----------
+
+Multiple lcores may not operate on the same crypto queue pair. The lcore that
+enqueues to a queue pair is the one that must dequeue from it.
