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/327db12c751be0375fcfed5e44b6065bcfb75c82 Changes since v1: - The cpuset field in telemetry is now a JSON list of CPU ids. - Applications must now report their raw CPU cycles counts. The busyness ratio and rate of change is left to external monitoring tools. - Renamed show lcores -> dump_lcores in testpmd. Robin Jarry (4): eal: add lcore info in telemetry eal: allow applications to report their cpu cycles utilization testpmd: add dump_lcores command testpmd: report lcore usage app/test-pmd/5tswap.c | 5 +- app/test-pmd/cmdline.c | 3 + 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 | 39 +++++++++- app/test-pmd/testpmd.h | 14 +++- app/test-pmd/txonly.c | 7 +- lib/eal/common/eal_common_lcore.c | 123 +++++++++++++++++++++++++++++- lib/eal/include/rte_lcore.h | 29 +++++++ lib/eal/version.map | 1 + 17 files changed, 234 insertions(+), 30 deletions(-) -- 2.38.1
