+Cross compile DPDK for ARM64
+============================
+This chapter describes how to cross compile DPDK for ARM64 from x86 build hosts.
+
+.. note::
+
+   Whilst it is recommended to natively build DPDK on ARM64 (just
+   like with x86), it is also possible to cross-build DPDK for ARM64. An
+   ARM64 cross compile GNU toolchain is used for this.
+
+Obtain the cross tool chain
+---------------------------
+The latest cross compile tool chain can be downloaded from:
+https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-linux-gnu/.
+
+Following is the step to get the version 7.2.1, latest one at the time of this writing.
+
+.. code-block:: console
+
+   wget https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-linux-gnu/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu.tar.xz
+
+Unzip and add into the PATH
+---------------------------
+
+.. code-block:: console
+
+   tar -xvf gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu.tar.xz
+   export PATH=$PATH:<cross_install_dir>/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin
+
+.. note::
+
+   For the host requirements and other info, refer to the release note section: https://releases.linaro.org/components/toolchain/binaries/latest/
+
+Getting the prerequisite library
+--------------------------------
+
+NUMA is required by most modern machines, not needed for non-NUMA architectures.
+
+.. note::
+
+   For compiling the NUMA lib, run libtool --version to ensure the libtool version >= 2.2,
+   otherwise the compilation will fail with errors.
+
+.. code-block:: console
+
+   git clone https://github.com/numactl/numactl.git
+   cd numactl
+   git checkout v2.0.11 -b v2.0.11
+   ./autogen.sh
+   autoconf -i
+   ./configure --host=aarch64-linux-gnu CC=aarch64-linux-gnu-gcc --prefix=<numa install dir>
+   make install
+
+The numa header files and lib file is generated in the include and lib folder respectively under <numa install dir>.
+
+.. _augment_the_cross_toolchain_with_numa_support:
+
+Augment the cross toolchain with NUMA support
+---------------------------------------------
+
+.. note::
+
+   This way is optional, an alternative is to use extra CFLAGS and LDFLAGS, depicted in :ref:`configure_and_cross_compile_dpdk_build` below.
+
+Copy the NUMA header files and lib to the cross compiler's directories:
+
+.. code-block:: console
+
+   cp <numa_install_dir>/include/numa*.h <cross_install_dir>/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin/../aarch64-linux-gnu/libc/usr/include/
+   cp <numa_install_dir>/lib/libnuma.a <cross_install_dir>/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/lib/gcc/aarch64-linux-gnu/7.2.1/
+
+.. _configure_and_cross_compile_dpdk_build:
+
+Configure and cross compile DPDK Build
+--------------------------------------
+To configure a build, choose one of the target configurations, like arm64-dpaa2-linuxapp-gcc and arm64-thunderx-linuxapp-gcc.
+
+.. code-block:: console
+
+   make config T=arm64-armv8a-linuxapp-gcc
+
+To cross-compile, without compiling the kernel modules, use the following command:
+
+.. code-block:: console
+
+   make -j CROSS=aarch64-linux-gnu- CONFIG_RTE_KNI_KMOD=n CONFIG_RTE_EAL_IGB_UIO=n
+
+To cross-compile, including the kernel modules, the kernel source tree needs to be specified by setting
+RTE_KERNELDIR:
+
+.. code-block:: console
+
+   make -j CROSS=aarch64-linux-gnu- RTE_KERNELDIR=<kernel_src_rootdir> CROSS_COMPILE=aarch64-linux-gnu-
+
+To compile for non-NUMA targets, without compiling the kernel modules, use the following command:
+
+.. code-block:: console
+
+   make -j CROSS=aarch64-linux-gnu- CONFIG_RTE_KNI_KMOD=n CONFIG_RTE_EAL_IGB_UIO=n CONFIG_RTE_LIBRTE_VHOST_NUMA=n CONFIG_RTE_EAL_NUMA_AWARE_HUGEPAGES=n
+
+.. note::
+
+   1. EXTRA_CFLAGS and EXTRA_LDFLAGS should be added to include the NUMA headers and link the library respectively,
+   if the above step :ref:`augment_the_cross_toolchain_with_numa_support` was skipped therefore the toolchain was not
+   augmented with NUMA support.
+
+   2. "-isystem <numa_install_dir>/include" should be add to EXTRA_CFLAGS, otherwise the numa.h file will get a lot of compiling
+   errors of Werror=cast-qual, Werror=strict-prototypes and Werror=old-style-definition.
+
+   An example is given below:
+
+   .. code-block:: console
+
+      make -j CROSS=aarch64-linux-gnu- CONFIG_RTE_KNI_KMOD=n CONFIG_RTE_EAL_IGB_UIO=n EXTRA_CFLAGS="-isystem <numa_install_dir>/include" EXTRA_LDFLAGS="-L<numa_install_dir>/lib -lnuma"
+
+Meson Cross Compiling DPDK
+--------------------------
+
+To cross-compile DPDK on a desired target machine we can use the following
+command::
+
+	meson cross-build --cross-file <target_machine_configuration>
+	ninja -C cross-build
+
+For example if the target machine is arm64 we can use the following
+command::
+
+	meson arm64-build --cross-file config/arm/arm64_armv8_linuxapp_gcc
+	ninja -C arm64-build
