[RISC-V][Devboards Program] April 1st, Devboards Program, 2025 - East-friendly

[Greg Sterling]

Our next meeting will be tomorrow.  Local times can be found by logging into LFX at https://lfx.linuxfoundation.org/tools/ or going to the Tech Meetings calendar at https://tech.riscv.org/calendar/.

The agenda will focus on standard topics:

• Program updates from RISC-V
• Board and Project updates
• Future Board Program Discussion
• What's cool?
  
• Misc Notes

Any topics, updates, or information can as always either be raised at the beginning of the meeting or by adding it to our agenda document, Dev Board Group Minutes (moved back to Google Docs).  Please note we have migrated to Confluence for meeting minutes.  Please reach out if you have any issues viewing the meeting minutes.

Thanks, and I look forward to seeing you tomorrow!

• [Bruno] Blog posts: https://bruno.verachten.fr

• Using two BananaPi F3 boards from the Devboards Program, we've been driving a large-scale riscv64 upstream contribution campaign:

• 30+ PRs opened to add riscv64 wheel builds to top Python packages (numpy, scikit-learn, SQLAlchemy, cryptography ecosystem, cffi, and more)

• 5 PRs already merged upstream (Docker CLI, pyzmq, jiter, SQLAlchemy, wit-bindgen)

• Collaboration launched with RISE (Ludovic Henry, TSC Co-Chair); 50 native riscv64 GitHub Actions runners coming online

• These are not running on the F3!

• AI workloads tested: NanoClaw AI agent runtime, llama.cpp, PyTorch on riscv64

• The F3 boards run 24/7 as native build verification machines; every package is proven to compile on real RISC-V hardware before submitting upstream PRs.

• CI/CD

• Greg building kiwi-ng VMDK image for certification

• ACT4 runner is using “unknown” GCC vs. SUSE using “suse”

• Future: container instead of VM

• How will test suite work on actual hardware as opposed to QEMU?
