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
