+Cross compiling 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.
+   like with x86), it is also possible to cross compile DPDK for ARM64.
+   An ARM64 cross compiler GNU toolchain or an LLVM/clang toolchain
+   may be used for cross-compilation.
 
-Obtain the cross tool chain
----------------------------
-The latest cross compile tool chain can be downloaded from:
+
+Prerequisites
+-------------
+
+NUMA 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 v2.0.13 -b v2.0.13
+   ./autogen.sh
+   autoconf -i
+   ./configure --host=aarch64-linux-gnu CC=<compiler> --prefix=<numa install dir>
+   make install
+
+.. note::
+
+   The compiler above can be either aarch64-linux-gnu-gcc or clang.
+   See below for information on how to get the compiler of your choice.
+
+The numa header files and lib file is generated in the include and lib folder respectively under <numa install dir>.
+
+Meson prerequisites
+~~~~~~~~~~~~~~~~~~~
+
+Meson depends on pkgconfig to find the dependencies.
+The package ``pkg-config-aarch64-linux-gnu`` is required for aarch64.
+To install it in Ubuntu::
+
+   sudo apt install pkg-config-aarch64-linux-gnu

-Getting the prerequisite library
---------------------------------
-
-NUMA is required by most modern machines, not needed for non-NUMA architectures.
+Augment the GNU toolchain with NUMA support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 .. note::
 
-   For compiling the NUMA lib, run libtool --version to ensure the libtool version >= 2.2,
-   otherwise the compilation will fail with errors.
+   This way is optional, an alternative is to use extra CFLAGS and LDFLAGS.
+
+Copy the NUMA header files and lib to the cross compiler's directories:
 
 .. code-block:: console
 
-   git clone https://github.com/numactl/numactl.git
-   cd numactl
-   git checkout v2.0.13 -b v2.0.13
-   ./autogen.sh
-   autoconf -i
-   ./configure --host=aarch64-linux-gnu CC=aarch64-linux-gnu-gcc --prefix=<numa install dir>
-   make install

+Cross Compiling DPDK with GNU toolchain using Meson
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+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 aarch64 we can use the following
+command::
 
-.. _augment_the_cross_toolchain_with_numa_support:
+   meson aarch64-build-gcc --cross-file config/arm/arm64_armv8_linux_gcc
+   ninja -C aarch64-build-gcc
 
-Augment the cross toolchain with NUMA support
----------------------------------------------
+
+LLVM/Clang toolchain
+--------------------
+
+Obtain the cross tool chain
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The latest LLVM/Clang cross compiler toolchain can be downloaded from:
+https://developer.arm.com/tools-and-software/open-source-software/developer-tools/llvm-toolchain.
+
+.. code-block:: console
+
+   # Ubuntu binaries

+
+The LLVM/Clang toolchain does not implement the standard c library. The GNU toolchain
+ships an implementation we can use. Refer to obtain_GNU_toolchain_ to get the
+GNU toolchain.
+
+Unzip and add into the PATH
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console

-   This way is optional, an alternative is to use extra CFLAGS and LDFLAGS.
+   To use the NUMA library follow the same steps as for
+   augment_the_gnu_toolchain_with_numa_support_.
 
-Copy the NUMA header files and lib to the cross compiler's directories:
+The paths to GNU stdlib must be specified in a cross file. Augmenting the default

-   sudo apt-get install pkg-config-aarch64-linux-gnu
+On most popular Linux distribution it's not necessary to download

+On Ubuntu 18.04, you'll need these packages:

-	meson cross-build --cross-file <target_machine_configuration>
-	ninja -C cross-build

+Use the following command to cross-compile DPDK for your target machine::
