    • Nitin Saxena
    • Ed Kern
  • Action Items - Last Week
    • Sirshak: Follow up with Mohammed regarding ThunderX mgmt connectivity and mcbin - IP addresses allocated cavium-2 has IPMI connectivity but console still hanging. cavium-1,3 - Not able to connect to IPMI. - Create a higher LF ticket so that it is easier for Trishan/Acton/Venessa/Mohammed to follow up.
    • Sirshak to hold a call with Khem and Adarsh to understand the Vm_vhsot issue because of nested VMs - Contact established still working on analyzing the setup.
    • Sirshak to create consolidated ARM ecosystem xls to reflect CSIT effort. (Need to add the link to the excel sheet to AArch64 page) - Not Done will do it next week.
    • Honnappa: memcpy benchmarking - Micro benchmarks run on mcbin, qualcomm - vector Load/Store usually go to the LSU unit
    • Brian : CSIT-990(buildroot) - Nitin ran on mcbin, it is failing at a different place - Brian to continue next week
    • Brian to publish a pictorial representation of rx queues and tx queues in multicore case for mcbin. - Moved to next week
    • Khem to analyze make test failure in Taishan - 1804 - Tested with the latest code (make test), all test cases passing
    • ARM - For TG for deciding connectivity - MCBin and Taishan - Sirshak/Brian working on it.

    • Natalie - responsible for network PMD DPDK driver
    • 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
