Now you can put a SpacemiT K3 RISC-V processor in a Framework Laptop 13

The DC-ROMA RISC-V Mainboard III for the Framework Laptop 13 is now available for purchase for $699 and up. First announced earlier this year, it’s the latest in a line of mainboards that are designed to fit inside of Framework’s modular laptops. But it’s the most powerful model with a RISC-V chip to date.

At the heart of the new board is a 2.5 GHz SpacemiT K3 octa-core RISC-V processor. It’s […]

I’m not saying that #MSDOS should be ported to #ARM / #RISCV, I am just saying that it’s possible ;P

(In practice it would be more like an API clone in the same way MS-DOS was a CP/M API clone)

Milk-V Jupiter2 is mini PC with a SpacemiT K3 RISC-V processor

The Milk-V Jupiter2 is a compact computer powered by a SpacemiT K3 processor with an eight-core RVA23 compliant RISC-V processor, Imagination BXM-4-64-MC1 graphics, and support for up to 60 TOPS of AI performance.

Compared with the original Milk-V Jupiter, the new model should bring big CPU, GPU, and AI performance boosts. It also supports faster wired networking. But it also features a […]

ASM-editor is a modern web application for writing, executing and learning M68K assembler code (and MIPS, RISC-V, X86), which uses the SvelteKit framework and the Rust programming language.

Since our last news item, among other things, an introductory course on general assembly languages and an AI assistant in each editor that takes control of the editor and the emulator have been added.

Specs drift. Handwritten code doesn't keep up. What if JSON, INI Mermaid diagrams, and Markdown were your source of truth - and Rust macros handled the rest?

Tao Liu demonstrates exactly that: a workflow where structured, human-readable documents are transformed at compile time into strongly typed Rust code, applied to a working RISC-V assembler and linker.

I tested the impact of disabling RVC on the SpacemiT X100 with clang.
Enabling RVC resulted in a roughly 10% performance improvement, which is higher than I expected.

AFAIK while the X100 supports a handful of fusion pairs, those aren't compressed only. (bitwise+bitwise, mul+add, add+load/store, slli+sr*i)
The fetch bandwidth is 16-byte / cycle, so enough to saturate the 4-way decode without RVC, but may struggle to keep it feed, in branchy code. Though the Cortex-A76, also has a 16-byte fetch with a 4-wide decode.

So I'm not sure what the tells us about RVC exactly.
The additional L1I misses don't feel like they'd impact perf that much on their own.

Gentoo is now available for PineTab V.

This work brings a practical Gentoo setup for the PineTab-V, with patches, scripts and documentation to make the device more useful for development, testing and experimentation.

There is also a pre built image available, so you can test it more easily on the PineTab V and continue from there.

I will keep improving the repository with scripts, fixes and documentation.

Российский Альянс RISC-V: четыре двигателя экосистемы открытой архитектуры

Представьте, что вы строите продукт на процессоре, а ключевые правила игры задает один владелец архитектуры. Хотите выпустить свой совместимый чип, добавить нужные расширения или просто не хотите зависеть от поставки конкретного изделия? Но почти везде упираетесь в лицензирование, отсутствие открытого доступа к IP-ядрам, документации и сталкиваетесь с ситуацией когда условия доступа к технологиям могут меняться быстрее, чем ваш цикл разработки. В стабильные времена это воспринимается как "стоимость входа", но в менее дружелюбные - воспринимается как риск, который внезапно становится техническим. И пусть это звучит как рекламный слоган, но RISC-V предлагает другой базовый принцип: открытый стандарт команд, который можно реализовывать без разрешения на саму основу. Не "бесплатный процессор", а открытая спецификация, вокруг которой можно строить свои ядра и SoC, добавлять расширения и при этом оставаться в рамках общего стандарта. Это дает больше пространства для маневра именно там, где обычно больнее всего: в продуктах, которые выпускаются много лет, в требованиях к безопасности и в зависимости от чужих лицензий. Но открытость не спасает от хаоса. Если каждый будет делать "почти совместимый" вариант, рынок быстро превратится в зоопарк, где интеграция того или иного решения снова становится подвигом. Российский Альянс RISC-V как раз про то, чтобы этого не случилось: он собирает участников и переводит идею открытой ISA в работающую экосистему, где софт, платы, безопасность, обучение и регуляторные ожидания не живут отдельно. Ставки тут очень практичные: кто умеет договориться о правилах и проверять их на практике, тот быстрее доводит решения до рынка и поддерживает их с наименьшими затратами. Именно о том какую роль играет Альянс в становлении целостной экосистемы RISC-V в России и будет наш очередной материал.

I've started work on my #stealthsolar page, I'll host it on Squeak (it's a very low power, low resource web host that I run - check it out https://squeak.solarcene.community).

In preparation I've upgrade #Hugo to 0.160 as wanted to use the nice 'book' theme (https://github.com/alex-shpak/hugo-book).

If you'd like to have a small website hosted just get in touch, there is still space on Squeak!

Final take for PineTab-V for this experiment with Gentoo.

No web browser seems to compile, there's an error due to RISC-V architecture.
CPU is not fully optimized for this Tablet, since it is an experimental Tablet, there's plenty of room to improve it and enable hardware accelaration on Mesa.
Core GNOME applications work out of the box, if you want a tablet for office operations this is a great Tablet for it.

I wish the cool advances in the RISC-V space jump from AI to consumer hardware. I would love to have M*-level performance in a RISC-V CPU

Pinetab-v updates to you people.

Still compilling with a lot of warnings but still good, that's webkit-gtk a large alternative Web Engine.

I've tested Gnome and is really nice but needs some features to be polished.

Gentoo is very solid and one of the only ones to have an excellent risc-v support.

PS: I couldn't upload the tablet compilling video

linux kernel question regarding #copyfail CVE-2026-31431 I just tested a c version of the exploit (https://github.com/tgies/copy-fail-c) on a riscv64 linux 5.10.4 (milkv-duo) and get
```
[+] target: /bin/su
[+] payload: 2064 bytes (516 iterations)
socket(AF_ALG): Address family not supported by protocol
patch_chunk failed at offset 0
```

I tested it on another risc64 SBC with a newer kernel which gained root but it seems like the exploit doesn't work on this kernel.

I'll do some more digging #riscv #milkv

Noting also that until the release comes out you can download a release candidate tarballs of @nodejs #NodeJS 26 from the following locations if you want to test new Node 26 functionality such as the Temporal APIs:
- https://nodejs.org/download/rc/v26.0.0-rc.2/ for the officially supported platforms
- https://unofficial-builds.nodejs.org/download/rc/v26.0.0-rc.2/ for some of the unofficial/experimental platforms (including #riscv and #Alpine/musl)
