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\nChanges since v6:\n\n- Added release notes entry\n- Moved lcore role enum to name conversion in a function for reuse\n- Moved rte_lcore_register_usage_cb in a 23.03 block of eal/version.map\n- Style & indentation fixes\n- Use asprintf to format busy/total cycles in lcore_dump_cb\n\nChanges since v5:\n\n- Added/rephrased some inline comments to address reviews.\n- Added a new commit that adds the /eal/lcore/usage endpoint as\n suggested by Kevin and Morten.\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/5tswap.c | 5 +-\n app/test-pmd/cmdline.c | 3 +\n app/test-pmd/csumonly.c | 6 +-\n app/test-pmd/flowgen.c | 2 +-\n app/test-pmd/icmpecho.c | 6 +-\n app/test-pmd/iofwd.c | 5 +-\n app/test-pmd/macfwd.c | 5 +-\n app/test-pmd/macswap.c | 5 +-\n app/test-pmd/noisy_vnf.c | 4 +\n app/test-pmd/rxonly.c | 5 +-\n app/test-pmd/shared_rxq_fwd.c | 5 +-\n app/test-pmd/testpmd.c | 40 +++-\n app/test-pmd/testpmd.h | 14 +-\n app/test-pmd/txonly.c | 7 +-\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 | 227 ++++++++++++++++++--\n lib/eal/include/rte_lcore.h | 35 +++\n lib/eal/version.map | 3 +\n 19 files changed, 347 insertions(+), 45 deletions(-)", "diff": null, "prefixes": [ "v7", "0/5" ] }
