+Mellanox BlueField Board Support Package
+========================================
+
+This document has information about steps to setup Mellanox BlueField platform
+and common offload HW drivers of **Mellanox BlueField** family SoC.
+
+
+Supported BlueField family SoCs
+-------------------------------
+
+- `BlueField <http://www.mellanox.com/page/products_dyn?product_family=256&mtag=soc_overview>`_
+
+
+Supported BlueField Platforms
+-----------------------------
+
+- `BlueField SmartNIC <http://www.mellanox.com/page/products_dyn?product_family=275&mtag=bluefield_smart_nic>`_
+- `BlueField Reference Platforms <http://www.mellanox.com/page/products_dyn?product_family=286&mtag=bluefield_platforms>`_
+- `BlueField Controller Card <http://www.mellanox.com/page/products_dyn?product_family=288&mtag=bluefield_controller_card>`_
+
+
+Common Offload HW Drivers
+-------------------------
+
+1. **NIC Driver**
+
+   See :doc:`../nics/mlx5` for Mellanox mlx5 NIC driver information.
+
+2. **Cryptodev Driver**
+
+   This is based on the crypto extension support of armv8. See
+   :doc:`../cryptodevs/armv8` for armv8 crypto driver information.
+
+.. note::
+
+   BlueField has a variant having no armv8 crypto extension support.
+
+
+Steps To Setup Platform
+-----------------------
+
+Toolchains, OS and drivers can be downloaded and installed individually on the
+Web. But it is recommended to follow instructions at `Mellanox BlueField
+Software Website <http://www.mellanox.com/page/products_dyn?product_family=279&mtag=bluefield_software>`_.
+
+
+Compile DPDK
+------------
+
+DPDK can be compiled either natively on BlueField platforms or cross-compiled on
+an x86 based platform.
+
+Native Compilation
+~~~~~~~~~~~~~~~~~~
+
+Refer to :doc:`../nics/mlx5` for prerequisites. Either Mellanox OFED/EN or
+rdma-core library with corresponding kernel drivers is required.
+
+- make build
+
+.. code-block:: console
+
+        make config T=arm64-bluefield-linuxapp-gcc
+        make -j
+
+- meson build
+
+.. code-block:: console
+
+        meson build
+        ninja -C build
+
+Cross Compilation
+~~~~~~~~~~~~~~~~~
+
+Refer to :doc:`../linux_gsg/cross_build_dpdk_for_arm64` to install the cross
+toolchain for ARM64. Base on that, additional header files and libraries are
+required:
+
+   - libibverbs
+   - libmnl
+   - libmlx5
+   - libnl-3
+   - libnl-route-3
+
+Such required libraries can be cross-compiled and installed on to the cross
+toolchain directory like depicted in :ref:`getting_the_prerequisite_library`,
+but those can also be simply copied from the filesystem of a working BlueField
+platform. The following is to create such supplementary tarball on a BlueField
+platform.
+
+.. code-block:: console
+
+        mkdir -p aarch64-linux-gnu/libc
+        pushd $PWD
+        cd aarch64-linux-gnu/libc
+
+        # Copy libraries
+        mkdir -p lib64
+        cp -a /lib64/libibverbs* lib64/
+        cp -a /lib64/libmnl* lib64/
+        cp -a /lib64/libmlx5* lib64/
+        cp -a /lib64/libnl-3* lib64/
+        cp -a /lib64/libnl-route-3* lib64/
+
+        # Copy header files
+        mkdir -p usr/include/infiniband
+        mkdir -p usr/include/libmnl
+        cp -a /usr/include/infiniband/ib_user_ioctl_verbs.h usr/include/infiniband/
+        cp -a /usr/include/infiniband/mlx5*.h usr/include/infiniband/
+        cp -a /usr/include/infiniband/tm_types.h usr/include/infiniband/
+        cp -a /usr/include/infiniband/verbs*.h usr/include/infiniband/
+        cp -a /usr/include/libmnl/libmnl.h usr/include/libmnl/
+
+        # Create supplementary tarball
+        popd
+        tar cf aarch64-linux-gnu-mlx.tar aarch64-linux-gnu/
+
+Then, untar the tarball at the cross toolchain directory on the x86 host.
+
+.. code-block:: console
+
+        cd $(dirname $(which aarch64-linux-gnu-gcc))/..
+        tar xf aarch64-linux-gnu-mlx.tar
+
+- make build
+
+.. code-block:: console
+
+        make config T=arm64-bluefield-linuxapp-gcc
+        make -j CROSS=aarch64-linux-gnu- CONFIG_RTE_KNI_KMOD=n CONFIG_RTE_EAL_IGB_UIO=n
+
+- meson build
+
+.. code-block:: console
+
+        meson build --cross-file config/arm/arm64_bluefield_linux_gcc
+        ninja -C build
