Notes & Action Items

Board Updates:

• Beagle, SiFive, StarFive, RIOS, Allwinner, Microchip, SpacemIT, Milk-V

• Ultrarisc pcb layout has been finished, the development board will come back at the end of this month and be tested. Milk-V Titan will ship this board, expected October 15th. They plan to have at least one for NA Summit.

Program Updates:

• oreboot

• U-Boot

• Firmware

  • (Wei Fu) Trying to get EDK2 running on Milk-V Jupiter.

• Operating System

  • BSD - FreeBSD, NetBSD

    • The second ALPHA build for the FreeBSD 15.0 release cycle is now available with support for riscv64 - link

  • Linux - AlmaLinux, Arch Linux, Alpine Linux, Debian, Fedora, SUSE, Canonical

    • Arch Linux

      • Chromium 140 patches updated.

      • Electron 37 patches updated.

      • Node.js 24.7 patches updated.

      • Sophgo Linux Kernel updated to 6.16.0. Thanks to RevyOS Team!

      • GCC 15.1.1 / glibc 2.42 updates still in progress. There are more GCC issues ahead:

        • https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121652

        • https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121534

      • ROCm stalled as no builder can build composable-kernel anymore.

    • Ubuntu Summit Talk - Moving to RVA23

    • Linux Patches Posted for Enabling Tenstorrent Blockhole SoC

  • Android - AOSP

  • OpenEuler, seL4, NixOS, R9, Managarm

• Images

  • Development - Gentoo, FedoraVForce (Mirror US)

    • FedoraVForce

      • All images updated to Fedora 42, and recently made live cd for RISC-V machines.

      • Making images for new RISC-V systems

        • P550 and Megrez

      • Making CentOS images as well

        • Making EPEL packages

      • Trying to incorporate with Red Hat to see what the toolchain can be for RVA23

      • Currently building Fedora 43

    • Gentoo

      • Biggest holdup is the compilers.

      • SiFive upstreamed everything except the P550, and work is held off until gcc16 (hasn’t happened for gcc15).

      • Trying to put something together for the SpacemiT K1, but having issues with the GPU stack.

      • Some discussions to get the Imagination GPU support into the kernel.

        • Downside is all based on thead1520

• Compilers

  • "are we expecting that RVA20 to RVA23 will be a hard ABI break with a different dpkg-architecture and whatever gentoo does, or will you be able to mix and match packages?

    "the most recent CFI patches posted to libc-alpha change the size of jmp_buf depending on compile time __riscv_zicfiss (despite the type having 10+ unused words), which will break every Perl XS module across an incomplete transition (Perl_Interpreter contains a jmp_buf) and probably other things, but I'm not sure if this is actually a problem or if I'm the right person to bring it up if it is"

    "looks like glibc is going with a hard ABI break for CFI by adding a new word to jmp_buf instead of using one of the existing scratch words"

    "both x86_64/SHSTK and arm64/GCS did this without an ABI break, but here we are"

• CI/CD
