Linux 6.19 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 6.19 on the Linux Kernel Mailing List (LKML): No big surprises anywhere last week, so 6.19 is out as expected – just as the US prepares to come to a complete standstill later today watching the latest batch of televised commercials. The betting man would expect them all to be AI-generated, but maybe some enterprising company decides to buck the trend? Doubtful, but there’s always a slight chance. But for anybody outside the US, maybe taking the newest kernel out for a spin instead is an option? I have more than three dozen pull requests for when the merge window opens tomorrow – thank you to all the early maintainers. And as people have mostly figured out, I’m getting to the point where I’m being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to […]

FOSDEM 2026 schedule – Embedded, RISC-V, Robotics, Rust, Open Hardware, and more

FOSDEM 2026 will take place on January 31-February 1, with thousands of developers meeting in Brussels to discuss open-source software & hardware projects. The free-to-attend “Free and Open Source Software Developers’ European Meeting” gets more traction every year, and in 2026, there will be at least 1,113 speakers, 1,016 events, 70 tracks, and potentially close to 10,000 attendees. As usual, I’ll create a virtual schedule with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms, including “RISC-V”, “Robotics and simulation”, and “FOSS on Mobile”, among others. I’m aware some of the talks overlap by a couple of minutes or so… FOSDEM 2026 Day 1 – Saturday, January 31 10:40 – 11:15 – RISC-V Vector optimisations in FFmpeg by Rémi Denis-Courmont FFmpeg is the most versatile multimedia codec and format support library, and was […]

SpacemiT K3 “16-core” RISC-V SoC system information and (early) benchmarks

SpacemiT K3 is an upcoming RVA23-compliant 64-bit RISC-V processor based on X100 cores clocked at up to 2.5 GHz. So far, we had limited information, but SpacemiT gave remote access to one SpacemiT K3-powered server to Sander, and he was kind enough to share some system information and early benchmarks.

Let’s start with system information reported by inxi utility:

MUSE Book laptop review – Testing an octa-core RISC-V Linux laptop in 2026

SpacemiT sent me a sample of the MUSE Book RISC-V Linux laptop for review. It’s based on the SpacemiT K1/M1 octa-core 64-bit RISC-V SoC, ships with up to 16 GB of RAM, eMMC flash and/or NVMe SSD, and features a 14.1-inch IPS display with 1920×1080 resolution, WiFi 6 connectivity, a few USB ports, and more. I won’t go through all the hardware specifications since Leo already did that when he wrote about the MUSE Book Laptop in April 2024, along with a teardown, and additional details about the SpacemiT K1/M1 SoC. I’ll still do an unboxing and quickly check the hardware, but I’ll focus on the software part to show the progress with Bianbu OS 2.3 (Ubuntu 24.04-based) on RISC-V hardware, as I just did for the low-end StarFive JH7110S-based VisionFive 2 Lite SBC. It’s quite a long review, so if you are short on time, you can jump directly […]

Year 2025 in Review, CNX Software stats, and looking ahead to 2026

Time for the last post of 2025, as the year is almost over. I’ll look back at key developments and notable products launched in 2025, share some CNX Software website traffic statistics, and look ahead to 2026. Year 2025 in Review After 22 product releases in 2024, Raspberry Pi calmed down a little bit in 2025, and the highlights of the year included the Raspberry Pi 500+ mechanical keyboard, the 5-inch variant of the Raspberry Pi Touch Display 2, and a Raspberry Pi 5 1GB RAM. What didn’t quite stop were the accessories from third parties for Raspberry Pi SBC and Raspberry Pi Pico boards. The most exciting Arm SoC release of 2025 was probably the 12-core CIX P1 Armv9 SoC found in Radxa Orion O6 SBC, MINISFORUM MS-R1 Arm mini PC, and Orange Pi 6 Plus board, but while performance was fine, it was overhyped in 2024, and software […]

Bit-Brick Cluster K1 – A 4-slot RISC-V cluster board for SpacemiT K1-based SSOM-K1 system-on-module

Bit-Brick Cluster K1 is a cluster board designed to mount up to four SSOM-K1 system-on-modules powered by a SpacemiT K1 octa-core RISC-V processor. The board targets developers, researchers, and system integrators working on edge computing, AI workloads, and high-performance embedded applications. The Cluster K1 relies on an onboard Gigabit Ethernet switch chip to interconnect four core boards, giving each board an independent network port for fast and stable inter-node communication with automatic IP assignment. Other key features include USB 3.0/2.0 ports, HDMI output (master slot only), a USB Type-C debug port, an M.2 M-Key slot for storage expansion, a 3-pin fan power header, and dedicated power, reset, and download buttons. The SSOM-K1 system-on-module features a K1 octa-core 64-bit RISC-V CPU with vector extension and AI acceleration up to 2 TOPS. It ships with up to 8GB dual-channel LPDDR4X memory, up to 64GB eMMC flash, and offers dual Gigabit Ethernet, HDMI 1.4 […]

Linux 6.18 LTS release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.18 on the Linux Kernel Mailing List (LKML), which will likely become the next LTS kernel [update: it’s now official]: So I’ll have to admit that I’d have been happier with slightly less bugfixing noise in this last week of the release, but while there’s a few more fixes than I would hope for, there was nothing that made me feel like this needs more time to cook. So 6.18 is tagged and pushed out. Most of the last-minute fixes are minor fixes to drivers, with some random noise elsewhere (bluetooth, ceph, afs..). Nothing strikes me as standing out, but hey, there’s a shortlog appended if you want to see the details. And this obviously means that the merge window will open tomorrow, and I already have three dozen pull requests pending. Thanks. And as I already mentioned a couple of […]
