+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
+	cd dpdk
+	mkdir build
+	meson build (--reconfigure)
+	cd build
+	ninja
+	sudo ninja install
+
+	2. Prepare
+	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
+
+	3. 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.
