Commit Message

Zhangfei Gao Oct. 26, 2022, 10:54 a.m. UTC
Introduce a new crypto PMD for hardware accelerators based on UADK [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.
Thereby user application can directly use virtual address for device dma,
which enhances the performance as well as easy usability.

This patch adds the basic framework.

+UADK Crypto Poll Mode Driver
+============================
+
+This code provides the initial implementation of the UADK poll mode
+driver. All cryptographic operations are using UADK library crypto API,
+which is algorithm level API, abstracting accelerators' low level
+implementations.
+
+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.
+
+
+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
