See 35 :doc:`../cryptodevs/armv8` for armv8 crypto driver information. 36 37.. note:: 38 39 BlueField has a variant having no armv8 crypto extension support. 40 41 42Steps To Setup Platform 43----------------------- 44 45Toolchains, OS and drivers can be downloaded and installed individually from the 46Web. But it is recommended to follow instructions at 47`Mellanox BlueField Software Website 48<http://www.mellanox.com/page/products_dyn?product_family=279&mtag=bluefield_software>`_. 49 50 51Compile DPDK 52------------ 53 54DPDK can be compiled either natively on BlueField platforms or cross-compiled on 55an x86 based platform. 56 57Native Compilation 58~~~~~~~~~~~~~~~~~~ 59 60Refer to :doc:`../nics/mlx5` for prerequisites. Either Mellanox OFED/EN or 61rdma-core library with corresponding kernel drivers is required. 62 63make build 64^^^^^^^^^^ 65 66.. code-block:: console 67 68 make config T=arm64-bluefield-linux-gcc 69 make -j 70 71meson build 72^^^^^^^^^^^ 73 74.. code-block:: console 75 76 meson build 77 ninja -C build 78 79Cross Compilation 80~~~~~~~~~~~~~~~~~ 81 82Refer to :doc:`../linux_gsg/cross_build_dpdk_for_arm64` to install the cross 83toolchain for ARM64. Base on that, additional header files and libraries are 84required: 85 86 - libibverbs 87 - libmlx5 88 - libnl-3 89 - libnl-route-3 90 91Such header files and libraries can be cross-compiled and installed on to the 92cross toolchain directory like depicted in 93:ref:`arm_cross_build_getting_the_prerequisite_library`, but those can also be 94simply copied from the filesystem of a working BlueField platform. The following 95script can be run on a BlueField platform in order to create a supplementary 96tarball for the cross toolchain. 97 98.. code-block:: console 99 100 mkdir -p aarch64-linux-gnu/libc 101 pushd $PWD 102 cd aarch64-linux-gnu/libc 103 104 # Copy libraries 105 mkdir -p lib64 106 cp -a /lib64/libibverbs* lib64/ 107 cp -a /lib64/libmlx5* lib64/ 108 cp -a /lib64/libnl-3* lib64/ 109 cp -a /lib64/libnl-route-3* lib64/ 110 111 # Copy header files 112 mkdir -p usr/include/infiniband 113 cp -a /usr/include/infiniband/ib_user_ioctl_verbs.h usr/include/infiniband/ 114 cp -a /usr/include/infiniband/mlx5*.h usr/include/infiniband/ 115 cp -a /usr/include/infiniband/tm_types.h usr/include/infiniband/ 116 cp -a /usr/include/infiniband/verbs*.h usr/include/infiniband/ 117 118 # Create supplementary tarball 119 popd 120 tar cf aarch64-linux-gnu-mlx.tar aarch64-linux-gnu/ 121 122Then, untar the tarball at the cross toolchain directory on the x86 host. 123 124.. code-block:: console 125 126 cd $(dirname $(which aarch64-linux-gnu-gcc))/.. 127 tar xf aarch64-linux-gnu-mlx.tar 128 129make build 130^^^^^^^^^^ 131 132.. code-block:: console 133 134 make config T=arm64-bluefield-linux-gcc 135 make -j CROSS=aarch64-linux-gnu- CONFIG_RTE_KNI_KMOD=n CONFIG_RTE_EAL_IGB_UIO=n 136 137meson build 138^^^^^^^^^^^ 139 140.. code-block:: console 141 142 meson build --cross-file config/arm/arm64_bluefield_linux_gcc 143 ninja -C build 144
