Note: to get lab access, create a gpg key, upload it to keyserver, have it signed by a trusted anchor in a video call (fingerprint will be needed) and then an ARM authority (Tina) needs to send an e-mail to helpdesk@fd.io with your name, e-mail, keygrip and key fingerprint

      • https://jenkins.fd.io/view/csit/job/csit-dpdk-perf-report-iterative-2106-3n-tsh/
        • 2106 testing partial finished. 21.01.1 ongoing, should be done sometime next week. - closed
      • Leverage current spare TX2 server as 2-node topology performance test-bed.
        • Add new IPSec NULL encryption & decryption test cases - Juraj
          • Inbound IPsec: reproduced and need to investigate - Juraj
          • Flow cache with 1, 10 SPD entries slower, still investigating. Manual test local vs CSIT have different result on 1-10 SPD policies.
        • IPsec SPD input/output case ongoing
          • Adding IPsec SPD outbound test cases 64B 1, 100 and 1k SPD entries, 1, 2, 4 cores, on tx2 testbed - clarified
            • Flow cache on and off cases need to be measured.
          • L2 BD 20k test cases execute time too long, removed on taishan.
        • Steps to enable test case in CSIT https://gerrit.fd.io/r/c/csit/+/31863
        • 3n-tsh testbed unreachable, investigating right now - Juraj
          • TG firmware is under upgradation
          • Server unreachable due to firmware & driver update - resolved - update all done

    • VPP Path
      • Voting and working fine.
      • CentOS-8 jobs have been removed.
    • VPP Device
      • https://jenkins.fd.io/view/vpp/job/vpp-csit-verify-device-master-ubuntu2004-aarch64-1n-tx2/
      • VPP device testing issues may be caused by XL710 i40e fw or kernel module.
          • Try to reproduce with another set of firmware and etc but issues still exist
          • https://doc.dpdk.org/guides/nics/i40e.html
            • DPDK uses i40evf PMD and it is old and scheduled to be deprecated.
            • This is fixed in DPDK 21.05 version by making iavf PMD as default.
          • Use iavf PMD instead of i40evf on all VPP branches, waiting for the test results - not reproduced so far.
      • New issue: different error related moving VF from host to container(not involving dpdk/VPP) - just started investigating
        • /usr/bin/vpp[3789]: pci: 0000:91:02.0: open_vfio_iommu_group: open '/dev/vfio/141': Device or resource busy
          • Resulting in the same failure as before, only happen on AArch64 platform
          • Still see /dev/vfio resource busy error after linux kernel upgradation, but less frequently than before
          • Dig into the log for more details - Juraj
          • Narrow down whether some of those arguments are the reason behind this and that is indeed the case: --volume /dev/vfio:/dev/vfio causes the issue.
        • AVF interface creation issue:
          • Can't create AVF interface on VFs with configured VLAN - happens with latest i40e driver on tx2
            • race condition occur
            • try mounting a part of /dev/vfio to see if issue can be resolved
            • Run six rounds of tests with patch https://gerrit.fd.io/r/c/csit/+/34045 and looks good right now
              • Addressed comments, waiting Peter's review..
              • Will enable voting right soon after the patch gets merged
    • Shipment of new advanced server to the FD.io lab

          • Able to access FPGA platform, investigating adding vpp to buildroot filesystem - Lijian
            • Run standalone SVE test cases on FPGA
            • Ask for DMC 620 images to run for FPGA
            • Enable DMC 620 more close to real system, but performance will drop
            • Build a system using VPP memif and pktgen
    • VPP IPv6 Benchmarking and Profiling
      • VPP CLI 'ip route add ipv6_addr/mask' outputs wrong IPv6 routes with mask 123-128

        • The issue could be reproduced on Arm servers with the NIC with latest firmware version. (still reproduced, no update yet)
          • Moved the NIC from arm server to x86 server can easily update firmware, given script to reproduce, intel busy with other stuff, debugging in progress.
            • Intel folks debugged, tried updating firmware/drivers, VF driver updated, old driver: i40evf, new driver: iavf. After modified dpdk code by using iavf, issue can be fixed. Need to find proper solution of dpdk.
          • Try to reproduce with another set of firmware and etc but issues still exist

This fix will be ported to all the older VPP LTS release branches. Currently, the fix is planned only for VPP 20.09 release.
          • Use iavf PMD instead of i40evf on all VPP branches, waiting for the test results - not reproduced so far.

            • Intel folks debugged, tried updating firmware/drivers, VF driver updated, old driver: i40evf, new driver: iavf. After modified dpdk code by using iavf, issue can be fixed. Need to find proper solution of dpdk.

This fix will be ported to all the older VPP LTS release branches. Currently, the fix is planned only for VPP 20.09 release.
