To override what instruction set will be used, set the ``cpu_instruction_set``
parameter to the instruction set of your choice (such as ``corei7``, ``power8``, etc.).
+To build dpdk for AMD Zen CPU based platforms, pass ``-Dcpu_instruction_set=<znverX>``
+to meson when configuring the build folder initially. Supported options are znver1,
+znver2 and znver3.

``cpu_instruction_set`` is not used in Arm builds, as setting the instruction set
without other parameters leads to inferior builds. The way to tailor Arm builds
is to build for a SoC using ``-Dplatform=<SoC>`` mentioned above.
