+OCTEONTX FPAVF Mempool Driver
+=============================
+
+The OCTEONTX FPAVF PMD (**librte_mempool_octeontx**) is a mempool
+driver for offload mempool device found in **Cavium OCTEONTX** 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 OCTEONTX FPAVF PMD are:
+
+- 32 SR-IOV Virtual functions
+- 32 Pools
+- HW mempool manager
+
+Supported OCTEONTX 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.
+
+- ``CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL_DEBUG`` (default ``n``)
+
+  Toggle display of generic debugging messages
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the OCTEONTX 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 octeontx 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"
