## TODO List
|
|
|
|
|
|
- Create ToDo list (kanban)
|
|
|
- Major missing piece NCSI RMI piece (driver for LiteX)
|
|
|
- https://www.dmtf.org/sites/default/files/standards/documents/DSP0222_1.1.0.pdf
|
|
|
Built on RMII
|
|
|
- Tim has previously created [LibreBMC Open Items](https://docs.google.com/document/d/10RJUk_uXhku6FTnb-WtpIDHrkrEaWdAREF4wafYzfV4/edit)
|
|
|
- Google + Antmicro are working on getting PCI Express going on the Xilinx hardware using open source tools (symbiFlow.github.io)
|
|
|
- Currently target is to get https://github.com/timvideos/litex-buildenv/wiki/HowTo-HDMI2PCIe-on-NeTV2 working with fully open source tools.
|
|
|
- Currently deprioritized behind getting FPGA interchange work going.
|
|
|
- Seems like we can *probably* get by without PCIe initially.
|
|
|
- There is some work on Lattice PCIe stuff that was done in GSoC;

|
|
|
- https://github.com/ECP5-PCIe/ECP5-PCIe
|
|
|
- https://github.com/enjoy-digital/litepcie/blob/master/doc/architecture.png
|
|
|
- Need to understand what components are hard macro / (currently) encrypted HDL / currently open (LiteX) for both Lattice + Xilinx
|
|
|
- https://github.com/greatscottgadgets/bucatini
|
|
|
- Graphics / VGA support
|
|
|
- Currently a nice to have.
|
|
|
- Raptor has working HDMI on ECP5 via transceiver on Sparrowhawk, code upstream in LiteX
|
|
|
- Need PCIe endpoint to provide VGA controller to host
|
|
|
- Can currently display serial console via text terminal (BMC-driven)
|
|
|
- Start gateware repo (git)
|
|
|
- Create BOM for first hardware batch (git)
|
|
|
|
|
|
|
|
|
- Using HedgeDoc? Is there a folder for Meeting Notes like in Google Drive?
|
|
|
- [GoogleDrive folder for Meeting Agenda + Notes](https://drive.google.com/drive/folders/1k9F3ww5cQL30xQvUL1dt4DE5qLVLax_J)
|
|
|
- https://files.openpower.foundation/s/iZRseq3XLtRcjtX
|
|
|
- Improve SoftCore for FPGA purposes
|
|
|
- Can softcore reduce the size?
|
|
|
- http://j.mp/softcpus-on-fpgas
|
|
|
- 3 ways of core optimization : fpga / asic / education
|
|
|
- Hardware status
|
|
|
- Getting the IBM Machine (AC922)
|
|
|
- On the way, coming soon with a link
|
|
|
- Getting the Interposer for AC922
|
|
|
- Getting an interposer to Antmicro (Michael / Pieter / Karol)
|
|
|
- Getting the FPGA DC-SCM BMC boards
|
|
|
- Getting a board to IBM OzLab
|
|
|
- Currently lots of confusion between IBM and Antmicro.
|
|
|
- Need to get Antmicro hardware ASAP so they can replicate the IBM work.
|
|
|
- IBM being the only one doing hardware work is a huge roadblock here.
|
|
|
- Possible alternate (Lattice not Xilinx) Raptor has ModBMC (derived from RunBMC) product for use with Talos II/Blackbird
|
|
|
- October 2021 timeframe for retail launch
|
|
|
- Organize a discussion between Antmicro, Tim Ansell (Google), Raptor around getting Artix 7 / Xilinx board compatible with ModBMC for use with Talos hardware.
