- 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.

- 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
- /usr/bin/vpp[3789]: pci: 0000:91:02.0: open_vfio_iommu_group: open '/dev/vfio/141': Device or resource busy

- VPP community is responding this issue actively. - Juraj
- 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
- https://doc.dpdk.org/guides/nics/i40e.html
- DPDK uses i40evf PMD and it is old and scheduled to be deprecated. After using iavf PMD, the issue is not seen. This is fixed in DPDK 21.05 version by making iavf PMD as default. 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.
- New issue: different error related moving VF from host to containter(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

- vfio-pci driver may be the root cause
- 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.
- "Make Test Testcase Error or Failure" --> There was an intermittent VPP anomaly introduced last week with the change from shmem to socket transport for PAPI which causes the MAP unittests to fail [0]. The root cause is being addressed and should be fixed shortly.

- 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
- https://doc.dpdk.org/guides/nics/i40e.html

- Changes required to the servers:
- The power cable specifications will be 4 x 6ft 14 AWG C13 to C14 Power Cables.
- Need 2 Intel NICs XL710-QDA2 for each server.
- If there is space for 2 more cards, we should add 2 Mellanox cards SR-IOV capability.
- Disk size to 480G
- Both the servers should have the NICs in the same PCIe slots. It does not matter which PCIe slots the cards are in.
- Cables: N1, P1 to N2, P1 and so on
- Cables for IPMI and Management port: 2
- Will call a meeting once the ThunderX2 arrives to Dean, inviting Juraj/Vxxhost people in FD.io lab to make sure hardware ready.

- VPP Performance Test
- Performance data on Arm in official release 19.08 is available.
- Performance job is merged. https://jenkins.fd.io/view/csit/job/csit-vpp-perf-mrr-daily-master-3n-tsh
- Trending data recorded with https://docs.fd.io/csit/master/trending/introduction/introduction.html
- Trending page: https://docs.fd.io/csit/master/trending/index.html
- There's a Python API issue which affects all performance tests on Taishan server only.
- VPP Path
- Looks like it would be only build and unit test. VPP device and performance tests would run on the physical devices in the lab.
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3
- Tried cross-compiling with DPDK only.
- Initial cross-compiling is working fine.
- Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- There's issues to build vpp distros.
- what is not finished is packaging - currently we support Ubuntu's DEB packages for aarch64 architecture (make PLATFORM=aarch64-generic pkg-deb) this is what I currently am trying to sort out ...
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.
- Doesn't work, seems to be caused improper cross-building-tools. https://wiki.fd.io/view/VPP/Build_System_Deep_Dive
- https://gerrit.fd.io/r/#/c/vpp/+/21035/, VPP path cross compilation
- setup proper platform specific folder names in DEB packages
- proper architecture string included in the DEB package name
- Loop Nitin, Sachin, Honnappa, Lijian in container cross-compilation discussion.
- VPP Device
- Totally 29 VPP device test cases executed, and all passed on Arm servers.
- Currently VPP device is not executed per patch. Issue is still under investigation.
- VPP device job is running now and will be triggered per VPP patch and CSIT patch

- FD.io lab
- Confirm the power cable requirements for the Vexxhost lab Inform about the 2 servers coming to the lab - Juraj
- Current Configurations:
- RAM: 256G
- Disk: 480G SSD
- The boxes are coming with Qlogic cards which are not supported in VPP.
- Changes required to the servers:
- The power cable specifications will be 4 x 6ft 14 AWG C13 to C14 Power Cables.
- Need 2 Intel NICs XL710-QDA2 for each server.
- If there is space for 2 more cards, we should add 2 Mellanox cards SR-IOV capability.
- Disk size to 480G
- Both the servers should have the NICs in the same PCIe slots. It does not matter which PCIe slots the cards are in.
- Cables: N1, P1 to N2, P1 and so on
- Cables for IPMI and Management port: 2
- Will call a meeting once the ThunderX2 arrives to Dean, inviting Juraj/Vxxhost people in FD.io lab to make sure hardware ready.
- Require and install 1G NIC for the management port because of the 1G management switch. - Lijian
- Require two ThunderX2(currently only one thunderX2 in the lab) in FD.io lab
- Require one more ThunderX2 to form a normal cluster (1xThunderX + 2xThunderX2), to enable voting right for Arm servers in CSIT

- Looks like it would be only build and unit test. VPP device and performance tests would run on the physical devices in the lab.
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3
- Tried cross-compiling with DPDK only.
- Initial cross-compiling is working fine.
- Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- There's issues to build vpp distros.
- what is not finished is packaging - currently we support Ubuntu's DEB packages for aarch64 architecture (make PLATFORM=aarch64-generic pkg-deb) this is what I currently am trying to sort out ...
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.
- Doesn't work, seems to be caused improper cross-building-tools. https://wiki.fd.io/view/VPP/Build_System_Deep_Dive
- https://gerrit.fd.io/r/#/c/vpp/+/21035/, VPP path cross compilation

- VPP Performance Test
- Performance data on Arm in official release 19.08 is available.
- Performance job is merged. https://jenkins.fd.io/view/csit/job/csit-vpp-perf-mrr-daily-master-3n-tsh
- Trending data recorded with https://docs.fd.io/csit/master/trending/introduction/introduction.html
- Trending page: https://docs.fd.io/csit/master/trending/index.html
- If there's performance drop in CSIT performance testing, what action will be taken and who will take care of the drop?
- Currently trending data could be monitored manually only.
- https://jenkins.fd.io/job/csit-vpp-perf-verify-1908-3n-tsh/, takes a lots of time, 3 days, 61 hours (28 hours on x86)
- Daily job is running twice a day on x86; on Arm, it takes 16 hours and will run one time each day.
- Trying to fix all the failures with daily test in performance test. Basically almost all the tests passed locally.
- Some common failures due to Python bindings or something inside VPP image.
- VPP Path
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3
- Tried cross-compiling with DPDK only.
- Initial cross-compiling is working fine.
- Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- There's issues to build vpp distros.
- what is not finished is packaging - currently we support Ubuntu's DEB packages for aarch64 architecture (make PLATFORM=aarch64-generic pkg-deb) this is what I currently am trying to sort out ...
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.
- Doesn't work, seems to be caused improper cross-building-tools. https://wiki.fd.io/view/VPP/Build_System_Deep_Dive
- https://gerrit.fd.io/r/#/c/vpp/+/21035/, VPP path cross compilaion

- VPP Performance Test
- Performance job is merged. https://jenkins.fd.io/view/csit/job/csit-vpp-perf-mrr-daily-master-3n-tsh
- Trending data recorded with https://docs.fd.io/csit/master/trending/introduction/introduction.html
- Daily job is running twice a day on x86; on Arm, it takes 16 hours and will run one time each day.
- Trying to fix all the failures with daily test in performance test. Basically almost all the tests passed locally.
- Only 1 out of 199 test cases failed, 8 test cases show random 'show hardware-interfaces' failure.
- Some failures are related with 'show hardware-interfaces'/'show vhost dump', time-out.
- Juraj to send Lijian the commands/APIs in random dump failure.
- https://jira.fd.io/browse/CSIT-1453
- SFP eeprom dump is enabled with 'show hardware-interfaces detail' only. Patch is merged.
- Juraj will change CSIT script with 'show hardware-interfaces verbose', https://gerrit.fd.io/r/#/c/csit/+/21085/
- CSIT patch is merged.
- Adding Taishan test bed to CSIT Status: https://gerrit.fd.io/r/#/c/16850/
- Target: master trending job - firstly create trending graph from daily data; then create release report(require some manual work)
- Patch to generate daily data and trending graph is committed.
- VPP Path
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3
- Tried cross-compiling with DPDK only.
- Initial cross-compiling is working fine. Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.
- Doesn't work, seems to be caused improper cross-building-tools. https://wiki.fd.io/view/VPP/Build_System_Deep_Dive
- VPP Device
- VPP tap interface is not working on all Arm servers. Works on stable/1810, but not working on stable/1901.
- Have gone thru the whole patch, pmalloc module and tap interface code, but cannot identify the root-cause - Lijian
- Buffer allocate/free based pmalloc seems to be causing the problem.
- mmap() regions with normal page and huge-page have separate VA spaces.
- VPP tap interface is not working on all Arm servers. Works on stable/1810, but not working on stable/1901.
- Totally 29 VPP device test cases executed, and 26 cases passed, and only 3 tap related tests failed.
- Currently VPP device is not executed per patch. Issue is still under investigation.
- VPP device job is running now and will be triggered per VPP patch and CSIT patch

- Require two ThunderX2(currently only one thunderX2 in the lab) in FD.io lab
- Require one more ThunderX2 to form a normal cluster (1xThunderX + 2xThunderX2), to enable voting right for Arm servers in CSIT
- It’s 1RU blade ThunderX2.
- The machine will be handled by Dean’s team. Cambridge folk will set up the machine before sending it to FD.io lab.
- The machine should have a big RAM, more than 120G and 256G preferred.
- The machine should Three NICs (XL710-QDA2, 2x40G).
- The script assumes the two ThunderX2 have the same NIC type, same fiber SFP type, and NICs are plugged into same PCI slots.

- Require two ThunderX2(currently only one thunderX2 in the lab) in FD.io lab
- Require one more ThunderX2 to form a normal cluster (1xThunderX + 2xThunderX2), to enable voting right for Arm servers in CSIT
- It’s 1RU blade ThunderX2.
- The machine will be handled by Dean’s team. Cambridge folk will set up the machine before sending it to FD.io lab.
- The machine should have a big RAM, more than 120G and 256G preferred.
- The machine should Three NICs (XL710-QDA2, 2x40G).
- The script assumes the two ThunderX2 have the same NIC type, same fiber SFP type, and NICs are plugged into same PCI slots.

- VPP Hoststack
- iperf3 performance with Hoststack. - Sirshak has done some preliminary bench-marking, and compare kernel and VPP hoststack performance.
- ongoing perf analysis, two patches ongoing. Hotpots on memory copy or maybe other stuff. Will share patches with community.- Sirshak
- Sirshak is trying to set up one CSIT setup for everyone debugging VPP hoststack. Will share setup info
- Gorka is trying some optimal configs for VCL.
- VPP on both sides(iperf3 server and client) give a boost.(Reason unknown).
- Alternate test cases.
- Action Items - Last Week
- [Sachin] to introduce RFC for IPsec offload support in DPDK plugin.
- [Khem] Deployment of only L2 CSIT performance suite. Status: Working with Juraj to get scripts ready for jobs. - Need to prepare some scripts. First to understand how the script works and then add more options.
- [Lijian] Status on VPP path failures. Status: Still debugging. Still at early study stage.
- [Sirshak] Kernel Migration mcbin. Status: Sirshak to try inputs from garcia and damjan. - no progress so far.
