+UADK Crypto Poll Mode Driver
+=======================================================
+
+UADK crypto PMD provides poll mode driver
+All cryptographic operations are using UADK crypto API.
+Hardware accelerators using UADK are supposed to be supported.
+
+
+Features
+--------
+
+UADK crypto PMD has support for:
+
+
+Test steps
+----------
+
+   .. code-block:: console
+
+	1. Build UADK
+	$ git clone https://github.com/Linaro/uadk.git
+	$ cd uadk
+	$ mkdir build
+	$ ./autogen.sh
+	$ ./configure --prefix=$PWD/build
+	$ make
+	$ make install
+
+	* Without --prefix, UADK will be installed to /usr/local/lib by default
+	* If get error:"cannot find -lnuma", please install the libnuma-dev
+
+	2. Run pkg-config libwd to ensure env is setup correctly
+	$ export PKG_CONFIG_PATH=$PWD/build/lib/pkgconfig
+	$ pkg-config libwd --cflags --libs
+	-I/usr/local/include -L/usr/local/lib -lwd
+
+	* export PKG_CONFIG_PATH is required on demand,
+	  not needed if UADK is installed to /usr/local/lib
+
+	3. Build DPDK
+	$ cd dpdk
+	$ mkdir build
+	$ meson build (--reconfigure)
+	$ cd build
+	$ ninja
+	$ sudo ninja install
+
+	4. Prepare hugepage for dpdk
+	$ echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
+	$ echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
+	$ echo 1024 > /sys/devices/system/node/node2/hugepages/hugepages-2048kB/nr_hugepages
+	$ echo 1024 > /sys/devices/system/node/node3/hugepages/hugepages-2048kB/nr_hugepages
+	$ mkdir -p /mnt/huge_2mb
+	$ mount -t hugetlbfs none /mnt/huge_2mb -o pagesize=2MB
+
+	5. Run test app
+
+Dependency
+----------
+
+UADK crypto PMD relies on UADK library [1]
+
+UADK is a framework for user applications to access hardware accelerators.
+UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share
+the same page table between IOMMU and MMU.
+As a result, user application can directly use virtual address for device dma,
+which enhances the performance as well as easy usability.
