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

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

· Operating System

o BSD - FreeBSD, NetBSD

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

o 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

o Android - AOSP

o OpenEuler, seL4, NixOS, R9, Managarm

· Images

o 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

o "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

o 10xEngineers has continued to add github support

§ https://github.com/alitariq4589/nodejs-riscv

§ https://github.com/alitariq4589/dotnet-riscv

§ Latest https://github.com/alitariq4589/github-runner-riscv

o RISC-V-Runners repo for github actions

· RISC-V International

o NA Summit - registration, schedule

§ Keynote Speakers announced

o Developer Board Status
