The AMD GFX1250 IP is what's used by the new Instinct MI450 series accelerators. That's been around within the Linux kernel, AMDGPU LLVM compiler back-end, and related codebases the past year. Interestingly merged yesterday is a new "gfx1250-strict" target.

A SiFive engineer posted patches today for the GNU Compiler Collection (GCC) for adding -mtune=native -mcpu=native support for the compiler on RISC-V.

All of the PCI/PCIe subsystem updates for the in-development Linux 7.3 kernel were merged this week.

Google engineers responsible for the Chrome/Chromium web browser are experimenting with Flatpak packaging on Linux. They aren't yet committed to officially supporting Flatpak packages but for now are at least exploring the option.

Last year a multi-kernel architecture was proposed for the Linux kernel to allow multiple independent kernel instances to co-exist on a single physical machine. Each kernel with "multikernel" Linux can run on dedicated CPU cores whole sharing the underlying hardware resources. Linux 7.0-mk2 released today with the kernel patched for this multi-kernel behavior.

COSMIC Epoch 1.7 is out today as the newest update to this Rust-based open-source desktop environment with development led by System76.

LLVM 23.1 was released today on-schedule as the first stable release of the LLVM 23 series as the H2'2026 update to this open-source compiler stack.

The PorteuX Linux distribution focused on being a high performance, modular, and minimalist distro took to forking Xfce's xfwm4 window manager into "xfwm4-gl" for OpenGL compositing support. As part of that they developed a window manager / compositor benchmark for evaluating the performance and efficiency of typical operations. Their results are fascinating.

The latest criticism of the increased burden placed on open-source software project maintainers caused by AI / LLM agents is around too many bug reports effectively causing a "denial of service" attack on project maintainers.

With the Btrfs pull request for Linux 7.3 having delivered more performance optimizations with some ~3x and ~5x gains mentioned in specific areas, I was eager to test out the new Btrfs performance on the in-development kernel. In today's article are some benchmarks of Btrfs on Linux 7.2 stable compared to Linux 7.3 Git with some very enticing performance gains confirmed in various workloads.

Apple today unveiled the M6 as their first 2nm SoC design while also introducing the M5 Ultra as their first quad-die product.

The pull requests for the existing Paragon NTFS3 kernel driver as well as the new modern "NTFS" drivers have been submitted for the ongoing Linux 7.3 kernel cycle. Besides bug fixes, most notable among these NTFS file-system drivers are Windows System Compression "WOF" read support for the modern NTFS driver.

The Linux Device Mapper "DKM" framework for mapping block devices to higher-level virtual block devices doesn't see any major new features for Linux 7.3 but there are many bug fixes, including code clean-ups carried out by AI.

The in-development Linux 7.3 kernel is marking Nova Lake Xe3P graphics as stable in being enabled by default and no longer hidden behind the "force probe" flag. While on-by-default, there still are some features that have yet to land like the DisplayPort 2.1 ALPM functionality.

KDE developer David Edmundson is out today with a blog post around improvements that have been ongoing for the Plasma 6.8 release in improving the KDE remote desktop experience. As part of ensuring a good Wayland experience and hitting all the needs fulfilled by X11, Plasma 6.8 is seeing improvements for its remote desktop functionality.

Linux sound subsystem maintainer Takashi Iwai of SUSE submitted all of the sound feature updates last week for the Linux 7.3 kernel. Besides the continued AI/LLM-generated patch churn, the sound code for Linux 7.3 sees a lot of new hardware support.

The HID subsystem updates were recently merged for the ongoing Linux 7.3 kernel merge window. Among other hardware additions, the 2026 Valve Steam Controller is seeing initial kernel driver support.

A patch series being worked on for the ath11k mainline wireless networking driver for Qualcomm WiFi 6 / 802.11ax chipsets is yielding 7x lower latency or 2.2x throughput at identical latency.

The past few Linux kernel cycles have chipped away at AF_ALG functionality for that interface for user-space programs to access the kernel's internal cryptography API. Linux has been dropping AF_ALG features like zero-copy support and offloading. AF_ALG was quickly deprecated in Linux 7.2 while now for Linux 7.3 it's being further restricted.

While Firefox 152+ already offers experimental JPEG-XL support, Mozilla formally announced today their plans for officially shipping JPEG-XL image format support in the Firefox web browser.
