Copies of the Antitrust Guidelines are available at: Antitrust Guidelines

AGENDA

New News

  • Anything new this week?

Hardware Update

  • Lattice ECP5 version of DC-SCM

    • Still missing some chips, but they do have the ECP5. Covid outbreak stopped chips.

  • Follow up on new hardware possabilities; From last meeting:

Bringup

  • AntMicro has all the HW it needs to do bring-up on the AC922.

    • Todd sent a brief guide to Antmicro showing where the code is and steps taken by Mikey/co
    • Antmicro to attempt to replicate the results and then use these instructions as a start of the README
    • Update on this? Does AM have what they need?
      • Looks like AM has what they need on this

OCP DC-SCM 2.0 Working Group -- Meets bi-weekly

  • Todd to run a call with Google and some other key players to discuss our common direction for the 3.0 standard. Still WIP. Trying to define the functions/areas that we need to go after. Lots of moving parts here in the industry.

Conference Report follow ups

  • Nothing new yet. Working on setting up meetings with microsoft and ASPEED near term.

Communication / Collaboration

  • Still seem to be issues with sending iCal meeting invites.

    • Seems to add to the calendar, but puts in limited information
    • Update?

  • Standing Reminder: Everyone should be posting things into the #librebmc-sig slack channel.

Gateware

Update?

Simulation

  • Renode looks like a good option for a simulation environment for LibreBMC.
    • Todd to send note to Piotr with information on what we would like to do with Renode and where the links are to the code/etc. WIP

Soft Cores

  • OPF is funding an FPGA optimized soft core
    • Target was "VexRISCV" resource usage and performance. Todd to schedule a readout at a future meeting

Toolchain

Software

Updates?

FPGA Usage Barriers

  • List of opens (potential barriers) for using FPGAs as BMCs Update here?
    • Cost -- Munir to follow up
    • Soft Error Rates -- Munir to follow up
      • Hard fails roughly the same as an ASIC
      • Looks like Xilinx SER FIT is reasonable (<200).
      • And detectable and fixable with an image reload
    • Performance? 8X slower than an ASPEED?
    • Image size
      • Todd to follow up with Munir from Lattice

Project Ideas -- Running list of areas where we could use help

Workgroup Collaboration Tools

Community Involvement

  • How do we generate more activity/interest

    • Engage Universities -- There are interested universities

    • Todd to start a list of universities and contacts

    • Need clear work breakdown

    • Need Mentors

    • Offer badges/certificates

    • Offer Bounties

    • Major League Hacking Interships

      • Start end of May.
      • Need to sign up by end of March
      • Must have sponsors to guide students and hold office hours
      • We missed this window, but the next one starts in Sept and we will circle back on this in a month or so. We still need to think about detailed work tasks and who can be mentors
      • To use MLH, We need BoD (Board of Directors) approval

  • Need work items clearly identified and easily understood

    • Documentation -- We need build instructions, readmes, etc

      • Need someone replicate the FPGA/OpenBMC load from scratch
        • Then document the process for others to follow so they can replicate the results
          • Build all pieces -- Core, peripherals, OpenBMC,etc
        • Antmicro working this

    • Need official OpenBMC project and a makefile, bitbake/etc

    • Need the project broken down into manageable pieces

  • It was suggested that we should have a logo for libreBMC. Any thoughts from the team. Nice to have, but should not be a focus right now.

    • I did see an offer of help for a logo. I will follow up. TBD

Goals -- Need timelines on these -- WIP

  • Tasks defined and project broken down
  • Able to generate a bitstream for an FPGA using fully open source toolchain.
  • Have RTL suitable for real production usage that has software support in the upstream OpenBMC project.
  • Someone seriously starting to do a real (non-development) LibreBMC deployment.
  • Fully functional Gateware and OpenBMC code stack for AC922
  • Determine the performance/size
