- Q. Do the Intel onboard NICs support VFs via SRIOV on machiattobin boards ?
- A.[Natalie] We support it but it’s not formally released yet. Will be formally delivered in 18.09.
- BB - Kernel bypass uses UIO possible to do. [natalie] check support for VF for onboard NICs
- Q. If Yes, is it a hardware level support or supported in musdk also ?
- A.[Natalie] MUSDK is not relevant here. Intel NICs are using DPDK and ARM infrastructure directly. We support PCIE SR-IOV with both v4.4 and v4.14 kernels
- Q. Has anybody tested containers (docker) and any container orchestration system on mcbin (e.g Docker Swarm or Kubernetes) ?
- A.[Natalie] Yes.
- Q. K8s or Docker Swarn ?
- A. [Bin Arm Internal] K8s is good choice version(1.9.4). Use kubeadm to install k8s cluster.
- Q. VM inside a container works on ARM ?
- A. [Bin ARM Internal] Use Kata and Runv. Kata/Runv is the solution of hardware-virtualized containers.
- Q. Container within a Container(nested) works on ARM ?
- A.[Bin ARM Internal] ‘Docker in docker’ or ‘Docker of Docker’ can works well on Arm platform.

NXP does cross compilation most of the time.

- Dmitri Epshtein - Responsible for crypto driver expert
- fd.io lab
- Follow up on ThunderX to getting mgmt IP - IP addresses are assigned, but are not up yet.
- Release Machine to EdK as soon as ThunderX is up.
- Cavium has shipped more machines as well - Delivered a week back. Tina to follow up with Trishan.
- See the Taishan setup for any VM issue. - Sirshak is trying to reproduce the issue.
- VPP
- VPP-1064 Dave Barach rejected the patch based on the solution Damjan and Nitin had decided upon following the reason that current approach breaks cross compilation. - NXP has upstreamed the DPAA2 patch, uses a separate segment makefile (dpaa.mk) for DPAA2. NXP does cross compilation most of the time. The approach could be that all platforms create a segment makefile and combine all of them into a single ARMv8 segment makefile.
- One solution suggested was creating a platform specific Makefile for ThunderX
- Honnappa Suggested as this not just a ThunderX issue but also Qualcomm issue hence a ARM specific Makefile would be better.(Issue 128 byte Cache Line Size)
- Honnappa no update on memcpy benchmarking will do that next week
- 1019: fixed in local will upstream soon - Patch has issues and some of the issues are fixed
- 1021: Patch submitted centos env issue CSIT follow up. - This can be closed
- 1023: migrated to openssl using DPDK manual but facing failed TCs - openSSL is integrated in his local environment - VPP not stable in his environment - Updated in the ticket.
- 1043: No updates
- 990: Brian to Retry on mcbin
- 1267: l3fwd performance tuning: Marvell to upstream a patch to enable dpdk on mcbin by making changes to dpdk plugin in vpp.
- Auto-detection of memory channels: Andrew's comment no really way to do that hence to go with making it a runtime argument via startup conf instead of being hard coded.
- Sachin facing issues with build rpm currently on 1801 will open a Jira Tkt if issues persists with 1804.
- CSIT
- Adarsh stalled with failure of test cases after using openssl.
- Performance Testing Khem : NUMA node numbering issue.
- NUMA node no issue not seen in ThunderX. Khem to post the details of issue and the workaround on Taishan.
- Khem facing issues with trex installation on ARM hence he will try getting a x86 machine as TG.
- Nitin known issue with trex with arm and mellanox card.
- Khem to try L2BD and L2XC.
- brian to use cache stashing and see the results.
- Action Items - Next Week
- Nitin: Run a VPP performance test to understand if the memcpy neon version provides any benefits.
- Sirshak: Create a higher LF ticket so that it is easier for Trishan/Acton/Venessa/Mohammed to follow up on bringing up ThunderX/mcbin
- Nitin: start email discussion with Dave to address the creation of single makefile for all ARMv8 devices
