OpenSBI

  • Prepare for an update to v1.7 (but Debian was faster and there update was merged). Thanks to @vhaudiquet for his patches submitted to Debian.
  • Test v1.7 on boards supported by Ubuntu 24.04

U-Boot

  • Prepare update to v2025.10 in PPA
  • Enable StarFive VisionFive 2 Lite, Milk-V Mars CM (Lite and eMMC)

Milk-V Mars CM

  • Test on Raspberry Pi Compute Module 5 IO Board:
    NVMe is not usable because of missing PCIe Power Enable line on Mars CM

Resolute

  • Keeping up work for inetutils merge LP: #2130124
    • Should be solved by disabling utmp features on Ubuntu
  • OpenSBI 1.7 with compatibility patches is coming from Debian to Ubuntu!

RISC-V

  • Investigating the status of Flutter on RISC-V
    • The flutter tool needed patches for RISC-V support: PR #178711
    • Flutter engine build system needed patches for RISC-V: PR #178712
    • Depending on the outcome, we might still need to build and distribute that engine ourselves
    • With those patches, the desktop-security-center and app-center can be built for RISC-V!

Overall I’m transitioning from a focus on Rust to a focus on LLVM:

Hello,

cargo-auditable

  • Finished and presented a patch that adds opt-in cargo-auditable support to SOME packages built with rustc. It currently does not work on packages with dev-dependencies due to this exciting issue, but …
  • Worked on adding dev-dependencies support to cargo-auditable by creating fake stub packages for each dev dependency. This week I figured out some workflow improvements that genuinely increases (edit: decreases) my iteration time by 100x :slight_smile:
