Meeting summary

    1. Maciek Konstantynowicz (mackonstan, 15:00:10)
    2. Tibor Frank (tifrank, 15:01:58)

  2. Agenda bashing (mackonstan, 15:02:00)
    1. Vratko Polak. (vrpolak, 15:02:06)

  3. Inputs from projects - VPP (mackonstan, 15:03:30)
    1. Fan Zhang (fan_zhang, 15:03:41)
    2. Andrew, v22.02 artifacts being pushed to packagecloud (mackonstan, 15:03:59)
    3. Andrew, into rls directory, should be done in couple hours (mackonstan, 15:04:16)
    4. Andrew, few fixes came late, yday, i) vxlan fixing a crash in masterthat changed meaning of api and introduced another problem, now reverted; ii) mtu callback related for memif, virtio, may have meaningful impact on jumbo tests; (mackonstan, 15:09:06)
    5. Fan, related to above, chatted with dpdk dev who authored mtu/mfs changes in dpdk. this was done to unify mfs/mtu handing across multiple nic models and taking care of encap/decap offload in nic's (mackonstan, 15:10:37)
    6. Dave Wallace (dwallacelf, 15:12:08)
    7. Fan, re dpdk performance degradation report by Vratko in vpp-dev: this could, but because of defaulting to 1518B mfs/mtu, avx2 rx_burst functional call in linear mode (using couple of mbufs, with additional check), previously vpp was receiving 256 frames in one go, now it's 64 frames. (mackonstan, 15:15:26)
    8. Peter, looking at dpdk init debug, after interfaces go up, one can see dpdk rx_burst working with avx2 in linear mode (mackonstan, 15:17:24)
    9. Fan, need to double click if it's really the root cause behind the vpp rc2 regressions reported by Vratko on vpp-dev, 5-15% (feature-simple tests) throughput drop (mackonstan, 15:19:22)
    10. Vratko, Maciek, I/O "heavy" regression, the more features one uses, the lower the regerssion; the simpler the config the higher regression. (mackonstan, 15:20:04)

  4. Inputs from projects - TSC (mackonstan, 15:20:50)
    1. Maciek, Dave, hw budget allocation for dram for arm build servers, and mlx connectx5s for trex 100ge nics for clx testbeds (mackonstan, 15:23:02)
    2. Dave, TSC chair nomination period is coming to an end this week (mackonstan, 15:23:43)
    3. Dave, this will be followed by voting among TSC members (mackonstan, 15:23:56)

  5. New or (to be) refactored tests (mackonstan, 15:24:20)
  6. VPP RC1, RC2 hot patch(es) items (mackonstan, 15:25:28)
    1. Peter, i) jumbo frames are supported in af_xdp kernel code up to "memory alignment" ~3kB, no support for 9000B; ii) jumbo frames issue with vpp memif, bug to be tracked re support mtu; (mackonstan, 15:28:13)
    2. Vratko, iii) found the place where vpp sets default IP MTU to 9000B. (mackonstan, 15:29:46)
    3. Maciek, suggesting to discuss on csit-dev mailer how to re-design existing csit jumbo frame size tests (mackonstan, 15:31:11)

  7. Releases CSIT-2202 (mackonstan, 15:31:35)
    1. Tibor, all planned rc2 iterative tests are done; all but 2 coverage tests are done too. (mackonstan, 15:32:01)
    2. Tibor, all data is in master ver of report (mackonstan, 15:32:12)
    3. Tibor, failed tests, nothing unexpected, only known issues. Vratko working thru them, Viliam composed summary, sent to csit-report. (mackonstan, 15:34:21)
    4. Tibor, draft report dynamic content validation, still to be completed fully (mackonstan, 15:35:31)
    5. Tibor, 2n-cix and 3n-icx testbeds added (mackonstan, 15:35:50)
    6. Tibor, static content updates - rls notes, RCA (mackonstan, 15:36:08)
    7. Tibor, static content - need to update environment versions (mackonstan, 15:36:26)

    10. https://lists.fd.io/g/vpp-dev/message/20888 (mackonstan, 15:38:34)
    11. Vratko, tsh tests are affected by TRex calibration … (mackonstan, 15:38:59)
    12. Vratko, for some regressions need more then 5 iterative runs (mackonstan, 15:41:08)

  8. Physical Infrastructure (mackonstan, 15:47:13)
