AGENDA

Getting hardware to people – Update

• There are 3 components;

  • AC922

    • Available for sale now for under $5K! Buy
    • 1 is in Rochester
    • 1 is in Australia
    • Loaner from IBM Poland to Antmicro is in process
    • Any further action on aquiring AC922s?
      • Antmicro is purchasing one and should have it soon
      • 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
    • 2 are in Rochester
    • 2 are in Australia
      • Delivered
    • 2 are en route to Antmicro
      • Reports are these have been delivered.
      • Looking for confirmation. Have not confirmed yet.
      • Todd to provide further information on tracking.

  • DC-SCM board – Need a bring-up plan

    • 4 boards, but only 3 have FPGAs
      • Update is Google is providing some to Antmicro. Shipping soon.
      • 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
    • 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

OCP Summit

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

  • Plan to ship from Rochester. Need a DC-SCM card in Rochester.
  • Likely will not have a live demo there, but we would like to have the hardware at the booth.

• LibreBMC was approved for a 5 minute “lightening” presentation.

  • Need to determine the key points to make and who will present

• Want a demo to be videotaped for display at the booth. Need to work on where/how. Australia or Antmicro would be the best options.

  • Antmicro to consider this option.
  • Antmicro will help.
  • What to show on the demo
    • BMCweb UI.
    • Lots of sensors/etc could be shown.
  • For a live demo, could just power on the DC-SCM card?
    • What could be shown without power on the board

• 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
  • Antmicro to update and co-present

Workgroup Collaboration Tools

LiteEth upstreaming

• Updates from Anton will wait until Tim A. is back

New agenda items for this week

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

  • Get to a full function FPGA
    • What is done and what remains?
    • See Paul’s list?
  • BoxArty : Presentation
  • New LPC driver being developed by Anton and Mikey
    • better intregation with OpenBMC
    • more in line with Linux and Wishbone
  • Get to a full function OpenBMC stack
    • YOCTO is functionally working on ppc64le
  • Determine if the performance of the FPGA is adequate

• What are our 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
  • Jeremy Kerr at codeconstructs is working on getting lattice parts working
