Board Updates:
Milk-V
OpenWRT can work on it , PLCT intern has tried it. But the kernel needs upstream.
Program Updates:
Arch Linux
[core] 256 / 264 (96.97%)
[extra] 12597 / 13383 (94.13%)
Fixes support of QEMU virtio block devices attached to pci bus: https://gitlab.archlinux.org/archlinux/mkinitcpio/mkinitcpio/-/merge_requests/264
Encountered a lot of new QEMU related crashes with latest QEMU 8.1.1: https://gitlab.com/qemu-project/qemu/-/issues/1913 https://gitlab.com/qemu-project/qemu/-/issues/1908 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111448 https://gitlab.com/qemu-project/qemu/-/issues/1921
Finished DDE (Deepin desktop environment) v23 packaging and it just works on Pioneer Box
Successfully run Minecraft with HMCL on Pioneer Box
119 PRs merged: ref. Some noted items:
Fedora
Fedora 38 Package number 22809/23285 [97.96%](less 440 srpms left)
The final Fedora 38 repo is under development(fixing dependencies, updating some packages), some packages(100+ rpms) can not be installed, because of dependency.
Debugging Deepin desktop, all the packages are built, install successfully, show desktop, but can not work, because of qt5 bug
Chromium can work on Fedora 38
LiveCD image is under development, you can install Fedora with LiveCD SD card. There is a issue when install kernel
RV32 bootstrap is done, New 64ILP32 is under development (PLCT intern). (Best performance for memory footprint smaller than 1 GB.)
K8s demo in RISC-V summit
Canonical
No updates on Pioneer box. Works when warm, not cold. Great for compiles.
PineTab-V looks like a good platform.
Working on updating to 6.5 kernel for VF V2 which should help PCI-e and USB support. Graphics output still not supported.
Actively participating in Profiles discussion which are presently focused on use of C extension (all 16-bit codes).
R9
Experimenting with paging and recursive page tables
Haven’t fully grasped it yet 😬
oreboot + LinuxBoot
Still working on HSM (Hart State Machine) thingies
We count on Linux getting patches in to handle unaligned access
We delegate it in oreboot, just like everything else

Discussed with others at Kernel Recipes, got this patch series to be worked on again 😀 (previous one few months prior had no reply)
See https://lore.kernel.org/linux-riscv/ for other series
Struggling with StarFive’s vs upstream Linux kernel; the latter hangs on MDIO read (ethernet MAC->PHY communication), while it works with StarFive’s kernel with a random phandle added as phy-supply in the ethernet DT nodes (whyever)
Daniel got two Milk-V Duo \o/
Ordered another Duo and 3 Duo IO boards (RPi form factor!) as well as (pre)ordered Mars (also RPi form factor) and Mars CM (CM should work in MNT Reform laptop) from https://arace.tech/collections/milk-v a month ago - no shipping confirmation yet 🙁 likely because of holidays 🏝️
would also like a Milk-V Meles (also RPi form factor), though not available (yet/anymore?); https://arace.tech/products/milk-v-meles
Firmware
Platform System Interface specification started documenting mask ROMs, loaders, and boot flows, using RISC-V in examples
