This is a much more basic and naive approach which leaves the cpu cycles accounting completely up to the application. For reference, I have implemented a draft patch in OvS to use rte_lcore_register_usage_cb() and report the already available busy cycles information. https://github.com/rjarry/ovs/commit/643e672fe388e348ea7ccbbda6f5a87a066fd919 v9: - Fixed changelog & version.map order. - Updated with 64-bit integer telemetry functions. - Refined docstrings (added notice about resetting the callback). - Fixed accounting of total cycles in testpmd. v8: - Made /eal/lcore/info lcore_id argument parsing more robust.
