  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

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.

Robin Jarry (5):
  eal: add lcore info in telemetry
  eal: report applications lcore usage
  app/testpmd: add dump command for lcores
  app/testpmd: report lcore usage
  eal: add lcore usage telemetry endpoint
