This is a follow up on previous work by Kevin Laatz: http://patches.dpdk.org/project/dpdk/list/?series=24658&state=*
This series is aimed at allowing DPDK applications to expose their CPU usage stats in the DPDK telemetry under /eal/lcore/info. 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 Changes since v6: - Added release notes entry - Moved lcore role enum to name conversion in a function for reuse - Moved rte_lcore_register_usage_cb in a 23.03 block of eal/version.map - Style & indentation fixes - Use asprintf to format busy/total cycles in lcore_dump_cb Changes since v5: - Added/rephrased some inline comments to address reviews. - Added a new commit that adds the /eal/lcore/usage endpoint as suggested by Kevin and Morten.
