+AMD EPYC SoC supports CPU power functions via `rte_power` API from `23.11 LTS` onwards. These are
+tested and valdiated on MILAN, GENOA, BERGAMO and SIENA using Linux kernel `6.4` and above with amd_pstate
+power driver.
+
+.. Note::
+        * Power libraries are supported on Linux only.
+        * DPDK uncore support on Linux is work in progress.
