The extensible scheduler framework "sched_ext" that allows for custom schedulers as BPF programs has been working on sub-scheduler support in recent kernel cycles. With Linux 7.3, sub-scheduler support is now deemed feature complete.

Tuned 2.28 released this Saturday as the newest version of Red Hat's tuning profile delivery mechanism for Linux. Tuned is used notably out-of-the-box on Fedora Linux for monitoring and adaptively tuning systems.

The open-source, reverse-engineered Etnaviv driver stack that began for providing accelerated graphics support on Vivante GPU IP and since expanded to handle Vivante NPUs as well is now able to handle YOLOX object detection.

The highlight of this week's x86/mm pull request of changes for the Linux 7.3 kernel are fixes that reduce the time that the TLB flushing code has interrupts disabled. This helps significantly with latency-sensitive workloads but Intel engineer Dave Hansen noted in the pull request that "it's certainly something to keep an eye on" in looking out for any regressions.

This Week in Plasma is out with its latest issue to highlight interesting developments in the trek towards Plasma 6.8.

OpenZFS 2.4.4 is out today as the newest stable point release for this ZFS file-system implementation for Linux and FreeBSD systems.

Wine 11.16 is out today as the newest bi-weekly development release for this software enabling Windows games and applications to run on Linux and other platforms.

Just in time for those that enjoy their Linux / Steam Play gaming on weekends, Valve and CodeWeavers today released Proton 11.0-2 as the newest stable release of this Wine 11.0 downstream that powers Steam Play for running Windows games gracefully on Linux.

Whether coincidental or intentional, AMD engineers tend to drop interesting, feature patches for the open-source/Linux space on Friday afternoons. Hitting the kernel mailing list minutes ago were two patch series sent out by AMDGPU maintainer Alex Deucher for introducing UALink infrastructure.

At a time when Linux continues dropping older hardware drivers due to the influx of AI/LLM-generated bug reports and patches for hardware extremely unlikely to be used with modern versions of the mainline Linux kernel, Voodoo graphics cards and vintage Atari computers are seeing some reprieve with the upcoming Linux 7.3 kernel release.

While the past few weeks have been quite busy with the new Framework Laptop 13 Pro testing with that all-new laptop model and paired with Intel's Core Ultra Series 3 "Panther Lake", at the same time Framework Computer has begun shipping some updated components for the Framework Laptop 16 laptop. If looking for a bit more GPU compute power hor larger form factor than the 13-inch model, the Framework Laptop 16 can now be equipped with the NVIDIA GeForce RTX 5070 GPU as well as a haptic touchpad and one-piece keyboard for improving the input experience.

In early 2025 I wrote about the upstream Nginx web server rejecting dark mode support for its error pages on the basis of wanting to keep the default error pages simple and developers arguing the extra HTML tag for the dark mode styling as superfluous. Following a lot of public backlash for being against offering native dark mode handling by default, Nginx stakeholders were polled and largely came out in favor of supporting the functionality but more than one year later it remains elusive from upstream Nginx.

The main set of media subsystem updates have been merged for the ongoing Linux 7.3 merge window. Notable this round is the Intel Computer Vision Sensing "CVS" driver merged the previous cycle now supporting next-gen Nova Lake platforms.

Merged this week for the Linux 7.3 kernel was a big clean-up to the stack randomization code for better security on Linux systems and helping unify some of the architecture-specific code.

Intel today released the Compute Runtime 26.31.39395.13 open-source GPU compute stack update for Windows and Linux systems. Big ongoing trends for the Intel Compute Runtime continue to be preparing for upcoming Crescent Island and Nova Lake Xe3P graphics hardware as well as building out their new OpenCL LEO driver.

With the mainline Linux 7.2 kernel there is now the basic support in place for CXL Type-2 accelerator drivers within the CXL core subsystem code. The first in-tree Type-2 driver with the Linux kernel is for the new AMD Solarflare NIC hardware.

It's pretty rare to see Linus Torvalds author patches himself pertaining to the open-source Linux graphics drivers, but waking up this morning I was surprised to see he authored and committed an Intel Xe kernel graphics driver change himself. It ended up being after he encountered a "debug session from hell" but was ultimately helped by AI in fixing a bug that had been irking him.

Intel's open-source Mesa drivers for Iris Gallium3D (OpenGL) and ANV (Vulkan) on Linux are no longer treating next-gen Nova Lake processors with integrated graphics as experimental and off-by-default. With today's Mesa 26.3-devel code, the Intel driver code across Nova Lake's S, U, H, and HX product families are considered stable and enabled by default.

All of the networking subsystem feature updates were merged today for the Linux 7.3 kernel's merge window. There are a lot of wired and wireless networking improvements this cycle but also a ton of bug fixes -- including many not so important fixes spun up by AI/LLM agents. The networking subsystem maintainers admit now they are "completely overwhelmed" due to this code churn from the output of AI large language models.

Rust 1.98 released today and is headlined the debut of new algebraic floating-point methods.
