Changwoo Min with Igalia presented yesterday at Open-Source Summit North America on optimizing the kernel's scheduler for Linux gaming. Of course, the motivation is around Valve's Steam Deck but for Linux gaming at large to benefit too from this scheduler work to ideally yield less stuttering during gameplay.

While we are all waiting for the NVIDIA R555 series Linux driver beta that is expected to debut as soon as next week based on prior information with Wayland improvements (explicit sync) and more, with the NVIDIA R560 series Linux driver successor is a very interesting change: NVIDIA is planning on defaulting to using their open-source GPU kernel driver by default for GeForce RTX 2000 "Turing" GPUs and newer.
Following last year Nouveau receiving support for running with the NVIDIA GSP firmware and initial GeForce RTX 40 series accelerated support, Ben Skeggs of Red Hat unexpectedly resigned as the Nouveau kernel driver maintainer. It turns out this longtime open-source Nouveau driver developer is now employed by NVIDIA Corp and continuing to work on the open-source Linux graphics driver.
Overnight systemd lead developer Lennart Poettering wrote on Mastodon around systemd's newest effort: run0 as a sudo-like command.
For those interested in some insightful Linux kernel mailing list reading this weekend, there's been a vibrant discussion on the ability for the Linux kernel to mitigate unexpected arithmetic overflows/underflows/wraparounds.
After not being ready in time for this week's early release target date, it's now been determined today that Fedora 40 is ready for release next week.
Linux Mint published their monthly status update for April 2024 where they talk about ongoing testing for faster and more reliable repository access via the Fastly CDN to other more interesting software happenings like the likelihood that they will fork more GNOME applications as well as looking to make their XApp applications more distribution agnostic.
Back in 2019 Microsoft open-sourced Cascadia Code as a font designed for terminals and code editors. The goals are similar to that of Intel's more recent One Mono as another open-source font for developers. It's been three years since the last update to the Cascadia Code open-source font while today rolled out version 2404.23.
The modular/upgradeable Framework Laptops employ an open-source embedded controller (EC) firmware derived from Google's Chrome OS EC project. This is great for open-source fans and allows re-using much of the same Chrome OS EC software support that already exists. But there is also vendor-specific commands supported by the Framework Laptop EC and thus a dedicated Linux kernel driver is now being worked on for handling those vendor/device-specific features.
While on Linux the desktop environments, graphics stack, and other application software is steadily adopting Wayland support and focusing less on X11/X.Org support, the state of Wayland support and the open-source graphics driver stack in general is less robust among the BSDs. The NetBSD project published a status report around their ongoing dependence and modifications to their X.Org stack.
After publishing open-source versions of MS-DOS years ago for versions 1.25 and 2.0, Microsoft and IBM have now announced that MS-DOS 4.0 has been open-sourced under an MIT license.
It's Fedora 40 release day! Fedora 40 is now available for download from mirrors for this leading Linux distribution.
In addition to all of the contributions Valve graphics engineers have been making to the open-source Radeon "RADV" Vulkan driver, they have also begun investing in improvements to the open-source Mesa NVIDIA "NVK" Vulkan driver too. With pending patches there is now explicit GPU synchronization support working for the NVK driver in conjunction with their Gamescope compositor.
Redox OS as the from-scratch, Rust-written open-source operating system had a successful April with now having USB keyboards and mice now working with their USB HID driver.
If your interest didn't pique enough when the former Nouveau lead developer joined NVIDIA and sent out a big patch series for this originally-reverse-engineered, open-source NVIDIA kernel driver, here's another plot twist: another NVIDIA engineer opening a merge request adding to the Mesa NVK Vulkan driver.
Systemd 256-rc1 is available this evening and it comes with many new features and improvements to existing features. It's a big one.
Linux kernel and Git creator Linus Torvalds is known for his current use of an AMD Ryzen Threadripper workstation as his main system after years of using Intel hardware. The past few years he's also been doing more ARM64 testing now that he has an Apple MacBook using Apple Silicon that serves as a nice travel device and for routinely compiling new ARM64 Linux kernel builds. More recently, his ARM64 Linux testing has increased now that he has a more powerful AArch64 system to complement his collection of routine gear.
After recently announcing they'd be working to get out Micro-Engine Scheduler (MES) firmware documentation and open-source code, AMD said they would be working to open-source more of their software stack and hardware documentation. AMD repeated those calls over the weekend.
Wine 9.8 is out today as the newest bi-weekly development release of this open-source software for enjoying Windows games/applications on Linux / Chrome OS, macOS, and other platforms.
While the Firefox web browser has long worked on AArch64 Linux and Mozilla even offers Windows ARM64/AArch64 binaries, to date Mozilla hasn't released official ARM64/AArch64 binaries for Linux. That is finally beginning to change.
The uutils' Rust-based Coreutils implementation is out with another update that further increases the drop-in replacement compatibility with GNU Coreutils.
While systemd 255 last year introduced a "blue screen of death" inspired solution with systemd-bsod for presenting logged error messages full-screen, it's not appropriate for all errors. Systemd-bsod can work out for presenting full-screen messages in case of boot failures and other problems where user-space is alive. But the user-space code does little good in case of a kernel panic and similar issues bringing the system to a halt. Set to be introduced now with Linux 6.10 is a parallel "blue screen of death" like error presenting experience with the introduction of the DRM panic handler.
The ReactOS project has posted their latest newsletter that outlines progress made during the past two months. ReactOS continues working to be an open-source operating system that offers application and driver binary compatibility with Microsoft Windows to in effect serve as a "open-source Windows" albeit the hardware support and application support are still an ongoing affair.
There's been a lot of improvements coming about in the GNOME desktop space thanks to the ongoing Sovereign Tech Fund and other initiatives toward GNOME 47.
The release ISOs for Ubuntu 24.04 "Noble Numbat" are now available! Ubuntu 24.04 is an exciting Long Term Support (LTS) update with this new Linux distribution release being powered by the Linux 6.8 kernel, making use of Netplan for networking on the desktop, features the modernized desktop OS installer, various performance optimizations, and a ton of new features.
