+Marvell cnxk Crypto Poll Mode Driver
+====================================
+
+The cnxk crypto poll mode driver provides support for offloading
+cryptographic operations to cryptographic accelerator units on the
+**Marvell OCTEON cnxk** SoC family.
+
+The cnxk crypto PMD code is organized into different sets of files.
+The file names starting with cn9k and cn10k provides support for CN9XX
+and CN10XX respectively. The common code between the SoCs is present
+in file names starting with cnxk.
+
+More information about OCTEON cnxk SoCs may be obtained from `<https://www.marvell.com>`_
+
+Supported OCTEON cnxk SoCs
+--------------------------
+
+- CN9XX
+- CN10XX
+
+Installation
+------------
+
+The OCTEON cnxk crypto PMD may be compiled natively on an OCTEON cnxk platform
+or cross-compiled on an x86 platform.
+
+Refer to :doc:`../platform/cnxk` for instructions to build your DPDK
+application.
+
+.. note::
+
+   The OCTEON cnxk crypto PMD uses services from the kernel mode OCTEON cnxk
+   crypto PF driver in linux. This driver is included in the OCTEON TX SDK.
+
+Initialization
+--------------
+
+``CN9K Initialization``
+
+List the CPT PF devices available on cn9k platform:
+
+.. code-block:: console
+
+    lspci -d:a0fd
+
+``a0fd`` is the CPT PF device id. You should see output similar to:
+
+.. code-block:: console
+
+    0002:10:00.0 Class 1080: Device 177d:a0fd
+
+Set ``sriov_numvfs`` on the CPT PF device, to create a VF:
+
+.. code-block:: console
+
+    echo 1 > /sys/bus/pci/devices/0002:10:00.0/sriov_numvfs
+
+Bind the CPT VF device to the vfio_pci driver:
+
+.. code-block:: console
+
+    cd <dpdk directory>
+    ./usertools/dpdk-devbind.py -u 0002:10:00.1
+    ./usertools/dpdk-devbind.py -b vfio-pci 0002:10.00.1
+
+.. note::
+
+    * 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.
+
+    * Ensure that sufficient huge pages are available for your application::
+
+         dpdk-hugepages.py --setup 4G --pagesize 512M
+
+      Refer to :ref:`linux_gsg_hugepages` for more details.
+
+``CN10K Initialization``
+
+List the CPT PF devices available on cn10k platform:
+
+.. code-block:: console
+
+    lspci -d:a0f2
+
+``a0f2`` is the CPT PF device id. You should see output similar to:
+
+.. code-block:: console
+
+    0002:20:00.0 Class 1080: Device 177d:a0f2
+
+Set ``sriov_numvfs`` on the CPT PF device, to create a VF:
+
+.. code-block:: console
+
+    echo 1 > /sys/bus/pci/devices/0002:20:00.0/sriov_numvfs
+
+Bind the CPT VF device to the vfio_pci driver:
+
+.. code-block:: console
+
+    cd <dpdk directory>
+    ./usertools/dpdk-devbind.py -u 0002:20:00.1
+    ./usertools/dpdk-devbind.py -b vfio-pci 0002:20:00.1
+
+Debugging Options
+-----------------
+
+.. _table_octeon_cnxk_crypto_debug_options:
+
+.. table:: OCTEON cnxk crypto PMD debug options
+
+    +---+------------+-------------------------------------------------------+
+    | # | Component  | EAL log command                                       |
+    +===+============+=======================================================+
+    | 1 | CPT        | --log-level='pmd\.crypto\.cnxk,8'                     |
+    +---+------------+-------------------------------------------------------+
+
+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.
