This is a much\nmore basic and naive approach which leaves the cpu cycles accounting\ncompletely up to the application.\n\nFor reference, I have implemented a draft patch in OvS to use\nrte_lcore_register_usage_cb() and report the already available busy\ncycles information.\n\nhttps://github.com/rjarry/ovs/commit/643e672fe388e348ea7ccbbda6f5a87a066fd919\n\nv9:\n\n- Fixed changelog & version.map order.\n- Updated with 64-bit integer telemetry functions.\n- Refined docstrings (added notice about resetting the callback).\n- Fixed accounting of total cycles in testpmd.\n\nv8:\n\n- Made /eal/lcore/info lcore_id argument parsing more robust.\n\nRobin Jarry (5):\n eal: add lcore info in telemetry\n eal: report applications lcore usage\n app/testpmd: add dump command for lcores\n app/testpmd: report lcore usage\n eal: add lcore usage telemetry endpoint\n\n app/test-pmd/cmdline.c | 3 +\n app/test-pmd/noisy_vnf.c | 7 +-\n app/test-pmd/testpmd.c | 42 +++-\n app/test-pmd/testpmd.h | 25 ++-\n app/test-pmd/txonly.c | 2 +-\n doc/guides/rel_notes/release_23_03.rst | 8 +\n doc/guides/testpmd_app_ug/testpmd_funcs.rst | 7 +\n lib/eal/common/eal_common_lcore.c | 219 ++++++++++++++++++--\n lib/eal/include/rte_lcore.h | 48 +++++\n lib/eal/version.map | 1 +\n 10 files changed, 329 insertions(+), 33 deletions(-)" }
