+Cavium OCTEON TX Crypto Poll Mode Driver
+========================================
+
+The OCTEON TX crypto poll mode driver provides support for offloading
+cryptographic operations to cryptographic accelerator units on
+**OCTEON TX** :sup:`®` family of processors (CN8XXX). The OCTEON TX crypto
+poll mode driver enqueues the crypto request to this accelerator and dequeues
+the response once the operation is completed.

+Compilation
+-----------
+
+The **OCTEON TX** :sup:`®` board must be running the linux kernel based on
+sdk-6.2.0 patch 3. In this, the OCTEON TX crypto PF driver is already built in.
+
+For compiling the OCTEON TX crypto poll mode driver, please check if the
+CONFIG_RTE_LIBRTE_PMD_OCTEONTX_CRYPTO setting is set to `y` in
+config/common_base file.
+
+* ``CONFIG_RTE_LIBRTE_PMD_OCTEONTX_CRYPTO=y``
+
+The following are the steps to compile the OCTEON TX crypto poll mode driver:
+
+.. code-block:: console
+
+        cd <dpdk directory>
+        make config T=arm64-thunderx-linuxapp-gcc
+        make
+
+The example applications can be compiled using the following:
+
+.. code-block:: console
+
+        cd <dpdk directory>
+        export RTE_SDK=$PWD
+        export RTE_TARGET=build
+        cd examples/<application>
+        make
+
+Execution
+---------
+
+The number of crypto VFs to be enabled can be controlled by setting sysfs entry,
+`sriov_numvfs`, for the corresponding PF driver.
+
+.. code-block:: console
+
+        echo <num_vfs> > /sys/bus/pci/devices/<dev_bus_id>/sriov_numvfs
+
+The device bus ID, `dev_bus_id`, to be used in the above step can be found out
+by using dpdk-devbind.py script. The OCTEON TX crypto PF device need to be
+identified and the corresponding device number can be used to tune various PF
+properties.
+
+
+Once the required VFs are enabled, dpdk-devbind.py script can be used to
+identify the VFs. To be accessible from DPDK, VFs need to be bound to vfio-pci
+driver:
+
+.. code-block:: console
+
+        cd <dpdk directory>
+        ./usertools/dpdk-devbind.py -u <vf device no>
+        ./usertools/dpdk-devbind.py -b vfio-pci <vf device no>
+
+Appropriate huge page need to be setup in order to run the DPDK example
+applications.
+
+.. code-block:: console
+
+        echo 8 > /sys/kernel/mm/hugepages/hugepages-524288kB/nr_hugepages
+        mkdir /mnt/huge
+        mount -t hugetlbfs nodev /mnt/huge
+
+Example applications can now be executed with crypto operations offloaded to
+OCTEON TX crypto PMD.
+
+.. code-block:: console
+
+        ./build/ipsec-secgw --log-level=8 -c 0xff -- -P -p 0x3 -u 0x2 --config
+        "(1,0,0),(0,0,0)" -f ep1.cfg
