AGENDA

Procedural update

  • Todd to run the late call with the Australians
  • Karol to run the Europe time call (this call)

Getting hardware to people – Update

There are 3 components: host system (AC922), Interposer board, DC-SCM Board.

  • AC922

    • 1 is in Rochester

    • 1 is in Australia

    • 1 is in Sunnyvale, USA @ Google

    • 1 is in Seattle, USA @ Google

    • Loaner from IBM Poland to Antmicro is in process

      • Some snags remain and are being worked through
      • No timeframe yet
    • Further action on aquiring AC922s

      • Antmicro is purchasing one and should have it soon
        • Snags have been worked through and reports are it should arrive in 3 weeks
      • VanTosh will also be purchasing at least one
  • Interposer

    • 6 pieces. Parts for 4 more are in Rochester
      • Next step is to have them built
      • Todd was unable to get into the office as planned due to Covid Restrictions
      • Todd has permission for tomorrow and plans to deliver the parts to card build
    • 2 are in Rochester
    • 2 are in Australia
      • Delivered
    • 2 are at Antmicro
      • Reports are these have been delivered.
      • They have been delivered!
  • DC-SCM board

    • 4 boards, but only 3 have FPGAs

      • Update is Google is providing some to Antmicro.
        • 6 weeks out at least
      • Also attempting to get some from China
      • Plan to have 10 total when the FPGAs arrive.
      • Need to be tested
    • Update: Australia can get into the plant, so best may be to send 1 DC-SCM to Australia for bringup in parallel with the Antmicro bringup.

      • Need general smoke test, RAM, ethernet test, GPIOs
      • Once the FPGAs come, they will test and ship to Australia
        • Since we are 3 weeks out on getting the AC922s to Antmicro, can we ship a smoke tested DC-SCM to IBM Australia ASAP? Karol to check.
    • Need to start working on getting Lattice parts for the DC-SCM board. Michael will take the lead on this.

      • PCBs sent in for production for lattice FPGA
      • Still need memory and ethernet parts
      • Marshall offered to help if there are issues getting FPGAs
    • Lattice was interested in having a Crosslink-NX / Cerbra DC-SCM board designed.
      *

OCP Summit

  • Todd to show the booth location and layout

  • Want to have a “LibreBMC” setup for OCP Summit booth

    • Plan to ship from Rochester. Need a DC-SCM card in Rochester.
    • Cannot power the AC922 at the booth
    • However, could we just power the DC-SCM card
      • The booth has only 1 2ft pedestal
      • Thinking just the AC922 hardware is what we will have.
      • There will not be a screen to show the demo
  • LibreBMC was approved for a 5 minute “lightening” presentation.

    • Need to determine the key points to make and who will present
  • In addition to the 5 minute live presentation, a 20-30 minute full presentation can be shown as a part of the virtual conference

    • First Deadline for submission is Oct 11th
    • Final Deadline is Oct 25th
  • Want a demo to be videotaped for that virtual conference presentation.

    • Antmicro will help to create the demo
    • What to show on the demo
      • BMCweb UI.
      • Lots of sensors/etc could be shown.
  • Presentation of LibreBMC to the OCP DC-SCM working group has been moved to the public meeting on the first week of October.

    • Todd to create initial set of charts
      • Still in progress
    • Antmicro to update and co-present
      • Todd to re-send the info regarding the meeting details
  • Yacoub Oulad Daoud yacoub@google.com is chasing Tim about slides for “A fully open source (tooling, hardware RTL, software) BMC”

Gateware

Software

LiteEth upstreaming

Workgroup Collaboration Tools

Recap from last meeting:

  • Top priority is booting an AC922 with OpenBMC on the Antmicro DC-SCM card using microwatt and a Xylinx FPGA

    • Desire is to have a full function FPGA and full function openBMC stack running
      • Not needed near term for the demo.
      • Would like this to prove the performance is adequate.
      • Need to work through priorities and next steps.
  • Next priorities beyond the above

    • Tim A thinks linux on LiteX
    • Tim A thinks focus on soft CPU. Smaller micro-watt. Goal is a 4 Core SMP complex on an Xilinx Artix 35T
    • Support Lattice FPGA
      • Other options for next priorities
    • Open tool chain support for new FPGAs
