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.
