This is a follow up on previous work by Kevin Laatz: http://patches.dpdk.org/project/dpdk/list/?series=24658&state=*
This is a much more basic and naive approach which leaves the busy cycles percentage completely up to the application. This series is aimed at allowing DPDK applications to expose their CPU busy cycles ratio in the DPDK telemetry under /eal/lcore/info. I have left it as RFC since calculating busy cycles can be a controversial topic. For reference, I have implemented a draft patch in OvS to use rte_lcore_register_busy_percent_cb() and report the already available busy cycles information. https://github.com/rjarry/ovs/commit/4286c0e75583075a223a67eee746084a2f3b0547 Robin Jarry (4): eal: add lcore info in telemetry eal: allow applications to report their cpu utilization testpmd: add show lcores command testpmd: report lcore usage app/test-pmd/5tswap.c | 5 +- app/test-pmd/cmdline.c | 31 ++++++++ app/test-pmd/csumonly.c | 6 +- app/test-pmd/flowgen.c | 2 +- app/test-pmd/icmpecho.c | 6 +- app/test-pmd/iofwd.c | 5 +- app/test-pmd/macfwd.c | 5 +- app/test-pmd/macswap.c | 5 +- app/test-pmd/noisy_vnf.c | 4 + app/test-pmd/rxonly.c | 5 +- app/test-pmd/shared_rxq_fwd.c | 5 +- app/test-pmd/testpmd.c | 69 +++++++++++++++- app/test-pmd/testpmd.h | 25 +++++- app/test-pmd/txonly.c | 7 +- lib/eal/common/eal_common_lcore.c | 127 +++++++++++++++++++++++++++++- lib/eal/include/rte_lcore.h | 30 +++++++ lib/eal/version.map | 1 + 17 files changed, 306 insertions(+), 32 deletions(-) -- 2.38.1
