+Octeontx ZIP Compression Poll Mode Driver
+=========================================
+
+The Octeontx ZIP PMD (**librte_pmd_octeontx_zip**) provides poll mode
+compression & decompression driver for ZIP HW offload 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
+--------
+
+Octeontx ZIP PMD has support for:
+
+Compression/Decompression algorithm:
+
+* DEFLATE
+
+Huffman code type:
+
+* FIXED
+* DYNAMIC
+
+Window size support:
+
+* 2 to 16K (2^14)
+
+Limitations
+-----------
+
+* Chained mbufs are not supported.
+
+Supported OCTEONTX SoCs
+-----------------------
+
+- CN83xx
+
+Steps To Setup Platform
+-----------------------
+
+ Octeontx SDK includes kernel image which provides Octeontx ZIP PF
+ driver to manage configuration of ZIPVF device.
+ Required version of SDK is "OCTEONTX-SDK-6.2.0-build35" or above.
+
+ SDK can be install by using below command.
+ #rpm -ivh CTEONTX-SDK-6.2.0-build35.x86_64.rpm --force --nodeps
+ It will install OCTEONTX-SDK at following default location
+ /usr/local/Cavium_Networks/OCTEONTX-SDK/
+
+ For more information on building and booting linux kernel on OCTEONTX
+ please refer
/usr/local/Cavium_Networks/OCTEONTX-SDK/docs/OcteonTX-SDK-UG_6.2.0.pdf.
+
+ SDK and related information can be obtained from: `Cavium support site
<https://support.cavium.com/>`_.
+
+Installation
+------------
+
+Driver Compilation
+~~~~~~~~~~~~~~~~~~
+
+To compile the OCTEONTX ZIP 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 install
+
+
+Initialization
+--------------
+
+The octeontx zip is exposed as pci device which consists of a set of
+PCIe VF devices. On EAL initialization, ZIP PCIe VF devices will be
+probed. To use the PMD in an application, user must:
+
+* run dev_bind script to bind eight ZIP PCIe VFs to the ``vfio-pci`` driver:
+
+ .. code-block:: console
+
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.1
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.2
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.3
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.4
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.5
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.6
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:00.7
+ ./usertools/dpdk-devbind.py -b vfio-pci 0001:04:01.0
+
+* The unit test cases can be tested as below:
+
+ .. code-block:: console
+
+ reserve enough huge pages
+ cd to the top-level DPDK directory
+ export RTE_TARGET=arm64-thunderx-linuxapp-gcc
+ export RTE_SDK=`pwd`
+ cd to test/test
+ type the command "make" to compile
+ run the tests with "./test"
+ type the command "compressdev_autotest" to test
+
