From: Harry van Haaren <harry.van.haa...@intel.com> This commit adds a new counter to be displayed to the user when requesting datapath packet statistics. It counts the number of packets that are parsed and a miniflow built up from it by the optimized miniflow extract parsers.
The ovs-appctl command "dpif-netdev/pmd-perf-show" now has an extra entry indicating if the optimized MFEX was hit: - MFEX Opt hits: 6786432 (100.0 %) Signed-off-by: Harry van Haaren <harry.van.haa...@intel.com> --- v5: - fix review comments(Ian, Flavio, Eelco) --- --- lib/dpif-netdev-avx512.c | 2 ++ lib/dpif-netdev-perf.c | 3 +++ lib/dpif-netdev-perf.h | 1 + lib/dpif-netdev-unixctl.man | 1 + lib/dpif-netdev.c | 16 ++++++++++------ tests/pmd.at | 6 ++++-- 6 files changed, 21 insertions(+), 8 deletions(-) diff --git a/lib/dpif-netdev-avx512.c b/lib/dpif-netdev-avx512.c index 91fad92db..645b4c9b4 100644 --- a/lib/dpif-netdev-avx512.c +++ b/lib/dpif-netdev-avx512.c @@ -311,8 +311,10 @@ dp_netdev_input_outer_avx512(struct dp_netdev_pmd_thread *pmd, } /* At this point we don't return error anymore, so commit stats here. */ + uint32_t mfex_hit = __builtin_popcountll(mf_mask); pmd_perf_update_counter(&pmd->perf_stats, PMD_STAT_RECV, batch_size); pmd_perf_update_counter(&pmd->perf_stats, PMD_STAT_PHWOL_HIT, phwol_hits); + pmd_perf_update_counter(&pmd->perf_stats, PMD_STAT_MFEX_OPT_HIT, mfex_hit); pmd_perf_update_counter(&pmd->perf_stats, PMD_STAT_EXACT_HIT, emc_hits); pmd_perf_update_counter(&pmd->perf_stats, PMD_STAT_SMC_HIT, smc_hits); pmd_perf_update_counter(&pmd->perf_stats, PMD_STAT_MASKED_HIT, diff --git a/lib/dpif-netdev-perf.c b/lib/dpif-netdev-perf.c index 7103a2d4d..d7676ea2b 100644 --- a/lib/dpif-netdev-perf.c +++ b/lib/dpif-netdev-perf.c @@ -247,6 +247,7 @@ pmd_perf_format_overall_stats(struct ds *str, struct pmd_perf_stats *s, " Rx packets: %12"PRIu64" (%.0f Kpps, %.0f cycles/pkt)\n" " Datapath passes: %12"PRIu64" (%.2f passes/pkt)\n" " - PHWOL hits: %12"PRIu64" (%5.1f %%)\n" + " - MFEX Opt hits: %12"PRIu64" (%5.1f %%)\n" " - EMC hits: %12"PRIu64" (%5.1f %%)\n" " - SMC hits: %12"PRIu64" (%5.1f %%)\n" " - Megaflow hits: %12"PRIu64" (%5.1f %%, %.2f " @@ -258,6 +259,8 @@ pmd_perf_format_overall_stats(struct ds *str, struct pmd_perf_stats *s, passes, rx_packets ?
