Getting hardware to people -- Update


  • Any update?

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. Still WIP

Conference Report follow ups

  • Nothing New

Communication / Collaboration

  • From Tim Ansell Seems to be a large amount of work being done which isn't being communicated. Is there a better way to communicate what all is being worked on.

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

    • Yes, this is still an issue, we have some work-arounds planned
    • Update?
  • Everyone should be posting things into the #librebmc-sig slack channel.




Workgroup Collaboration Tools

New Topics

  • How do we get more people involved? Nothing new here

    • Need to get ready images to consume by people
    • Need LiteX-Hub support and integration
    • Add more FPGA boards supports
    • Get it running on Raspbery PI
    • Then add some documentation
    • Badges and certificates
  • 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
  • Open the software stack to the world This is not new, but worth reminding us again of the next steps

    • Step 1: Get the FPGA/DC-SCM card booting the AC922

    • Step 2: Incorporate microwatt into lite-x natively.

    • Step 3: Enable others

      • Need others to be able to re-create the results.
      • Build all pieces -- Core, peripherals, OpenBMC,etc
      • Need official OpenBMC project and a makefile, bitbake/etc
      • Need the project broken down into manageable pieces
    • Step 4: Include the firmware into the CI infrastructure

    • Step 5: Enhancements -- hoping for further industry participation

      • Full FPGA support (I2C, FSI, etc) More than just bit banging
      • Resource usage -- Shrink micro-watt to get 4 cores.
        • See requirements from Tim A. on last call
      • Full OpenBMC support expected for a standard server
  • List of opens (potential barriers) for using FPGAs as BMCs

    • Cost -- Munir to follow up
    • Soft Error Rates -- Munir to follow up
    • Performance
    • Image size
    • Todd to get more
  • IDEAS for Making Progress

  • Incremental goal? Linux on LiteX VexRISCV like repository -- IE An example for just running a POWER Linux system on as many FPGA development boards as possible?

  • Set Goals -- Where do we want to be in 3mo, 6mo, 1 year?

    • Tasks defined
    • 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
  • Have someone replicate the FPGA/OpenBMC load from scratch

    • Toshaan said he would do this with help from Anton/Mikey
    • Todd to send him the DC-SCM board and interposer
    • Mikey to send him the ROT jumper
