  3. Physical labs, testbeds (mackonstan, 14:02:34)
    1. Jan/Peter: more issues with SSDs on Skx, even though FW got update, looks like a new issue. tb31 3n-skx is affected, currently operational, monitoring WIP. (mackonstan, 14:04:25)

  7. Inputs from projects - TSC (mackonstan, 14:05:16)

    1. Skx NDR issue - eno interrupts are spreading across all cores on TG TRex nodes. (mackonstan, 14:19:14)
    2. Skx NDR issue - only observed on Skx, not on Clx. TRex on Skx only, eno are mgmt interfaces could be related to ssh activity to TRex during test, but again this is not happening on Clx (same motherboard as Skx, same mgmt interface and driver) or other servers in CSIT lab. (mackonstan, 14:26:02)

  12. Operations (mackonstan, 14:41:10)
    1. Committers - Maciek has an action to update yaml file and screen contributors' work for any substantials to warrant additions to CSIT committer list (mackonstan, 14:42:34)

  13. VPP code performance (mackonstan, 14:44:17)
    1. Vratko - one regression in SRv6 most likely due to the VPP patch introducing API change, could be due to VPP or CSIT doing things differently, sent emails. (mackonstan, 14:45:32)
    2. Vratko - several false anomalies due to environment, some very fresh anomalies, waiiting to see if it's just a fluke or for real (mackonstan, 14:46:08)
    3. Jan - ip6scale tests, due to VPP change, Jakub Grajcar API changes broke VAT that is still used in CSIT for scale tests. (mackonstan, 14:47:23)
    4. Peter - vhost - open tickets for vpp, email to vpp-dev. (mackonstan, 14:47:45)
    5. Peter - avf - only skx affected, working on it. (mackonstan, 14:47:55)

  14. Developments (mackonstan, 14:48:19)
    1. CSIT - VM VHOST tests with rxq>1 failing [VPP-1853] (pmikus, 14:48:31)
    2. CSIT - VM VHOST tests with qemu mrg_rxbuf=off [VPP-1854] (pmikus, 14:48:52)
    3. Vratko - faster PAPI for scale tests, using async calls and faster method to synthetised the data to send and parse responses - progressing well, expecting slower than VAT, but much faster than today (e.g. ip4scale1m - VAT O(10sec), PAPI today O(30min), asyncPAPI O(~3min) (mackonstan, 14:51:34)
    4. Govind - having issues with moving to -72 kernel for Ubuntu 18.04 LTS, but was successful with -91. Is it okay to move to -91? (mackonstan, 14:56:25)
