Notes & Action Items

Board Updates:

• Beagle - blog

  •  This Week in Beagle #15: link - BB image Builder, PocketBeagle 2 Examples

• SiFive - press

  •  Unclear between SiFive, Eswin, Milk-V (for Megrez), etc… who has the appropriate kernel, they all have differences upstream and there is no merged repository at this time.

• StarFive

  •  

• RIOS - news

  •  

• Allwinner

  •  

• Microchip - news

  •  MPLAB AI Coding Assistant: Link

  • Extends maXTouch M1 Gen to support automative displays: Link

• SpacemiT - news

  •  

• Microsemi

  •  

• Milk-V - announcements

  •  

Program Updates:

• AlmaLinux

  •  

• Arch Linux

  •  Discussion on what to do on Vector enabled vs Vector not enabled packages… may have a separate repository that can give you packages compiled with Vector that overrides the non enabled packages.

• Alpine Linux

  •  

• FreeBSD

  •  

• OpenEuler

  •  

• Debian

  •  Trixie is becoming “slushy” (ie pre-freeze)

• Gentoo (Dev Images) link

  •  Updated Image posted for 02/19

  •  

• Fedora

  • Rolling Out More RISC-V Infrastructure & Ready-To-Boot Images: Link

  • Fedora Magazine announcement on support for RISC-V

  • Carl/Lance working on NA mirrors for FedoraVForce

• SUSE

  •  Got the Framework RISC-V board and running with vendor kernel.

• Canonical

  • Ubuntu 24.04.2 was published today.

• Android (AOSP)

  • People have said Builds running on SpaceMit K1, but Carl unable to find them yet. (22m boot?)

  • Banana Pi F3 build is around a 10-15m boot (debug build). link

• seL4

  •  Work on getting SiFive P550 working and upstreamed. Struggling a bit on U-Boot when handover to OS. Not passing hard id over.

• NixOS

  •  

• R9

  •  

• oreboot

  •  oreboot can run barebox just fine. Plus, it runs both in QEMU and RVVM

  • Got the platform timer on the K230 to work 

    • Needed to set a bit in a debug register that is not remotely documented to be related, someone else found it in vendor U-Boot code

  • Got SG2002 DRAM init to work, with a little hardcoding hack for now

    • Auto detection needs some fixing somewhere, complicated SBI test with timer works as well

    • Slowly getting there with Linux, currently having issues in virtual memory setup with kernel mapping

  • Working on libraries for oreboot

    • Architecture specific helpers for XuanTie platforms

    • Utilities for MMIO access dropping the unsafe (merged)

    • Memory copy and test (merged)

  • GitHub - platform-system-interface/psi-spec: Platform System Interface Specification

  • Platform System Interface

• Firmware

  •  

• Managarm

  • GitHub - managarm/managarm: Pragmatic microkernel-based OS with fully asynchronous I/O

• Linux Kernel

  • Phoronix occasionally posts kernel updates….   Linux 6.14 RISC-V Kernel Adds Support For T-Head Vector Extensions, GhostWrite

• RISC-V

  • Developer Board Status

    • Monthly Status Report

    • Final Status Report

  • Developer Experience

  • Running SAIL/ACT Tests on RISC-V Hardware?

  • Reports some people not seeing invite on their calendar

What’s cool?:

•  Ex Intel Exec raises $21.5 million for RISC-V chip startup AheadComputing: Link, Link

• U-Boot - http://github.com sg2042-dev "Das U-Boot" Source Tree. Contribute to sophgo/u-boot development by creating an account on GitHub.

Miscellaneous notes:

•  Wendell on the Premier P550, offering remote access:Checking Out The RISC V HiFive P550 from SiFive!
