+Please refer to :doc:`../linux_gsg/build_dpdk` for generic details on compiling DPDK with meson.

+In order to enable ``PMU`` based ``rte_rdtsc()``, user needs to configure the
+build with ``-Dc_args='-DRTE_ARM_EAL_RDTSC_USE_PMU'``.

+Example:
+
+.. code-block:: console
+
+   meson --cross config/arm/arm64_armv8_linux_gcc -Dc_args='-DRTE_ARM_EAL_RDTSC_USE_PMU' build
