Reuse the --record-core-cycles option to account for busy cycles. One turn of packet_fwd_t is considered "busy" if there was at least one received or transmitted packet.Add a new busy_cycles field in struct fwd_stream. Update get_end_cycles to accept an additional argument for the number of processed packets. Update fwd_stream.busy_cycles when the number of packets is greater than zero. When --record-core-cycles is specified, register a callback with rte_lcore_register_usage_cb(). In the callback, use the new lcore_id field in struct fwd_lcore to identify the correct index in fwd_lcores and return the sum of busy/total cycles of all fwd_streams. This makes the cycles counters available in rte_lcore_dump() and the lcore telemetry API: testpmd> dump_lcores lcore 3, socket 0, role RTE, cpuset 3 lcore 4, socket 0, role RTE, cpuset 4, busy cycles 1228584096/9239923140 lcore 5, socket 0, role RTE, cpuset 5, busy cycles 1255661768/9218141538 --> /eal/lcore/info,4 { "/eal/lcore/info": { "lcore_id": 4, "socket": 0, "role": "RTE", "cpuset": [ 4 ], "busy_cycles": 10623340318, "total_cycles": 55331167354 } } Signed-off-by: Robin Jarry <[email protected]> Acked-by: Morten Brørup <[email protected]> Acked-by: Konstantin Ananyev <[email protected]> --- Notes: v5 -> v6: No change. app/test-pmd/5tswap.c | 5 +++-- 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 ++++--- 13 files changed, 81 insertions(+), 27 deletions(-)
