Racing karts on a Rust GPU kernel driver (Collabora blog)

In July, Collabora announced the Rust-based Tyr GPU driver for Arm Mali GPUs. Daniel Almeida has posted an update on progress with a prototype of the driver running on a Rock 5B board with the Rockchip RK3588 system-on-chip: The Tyr prototype has progressed from basic GPU job execution to running GNOME, Weston, and full-screen 3D games like SuperTuxKart, demonstrating a functional, high-performance Rust driver that matches C-driver performance and paves the way for eventual upstream integration! [...] Tyr is not ready to be used as a daily-driver, and it will still take time to replicate this upstream, although it is now clear that we will surely get there. And as a mere prototype, it has a lot of shortcuts that we would not have in an upstream version, even though it can run on top of an unmodified (i.e., upstream) version of Mesa. That said, this prototype can serve as an experimental driver and as a testbed for all the Rust abstraction work taking place upstream. It will let us expe

[$] BPF and io_uring, two different ways

BPF allows programs uploaded from user space to be run, safely, within the kernel. The io_uring subsystem, too, can be thought of as a way of loading programs in the kernel, though the programs in question are mostly a sequence of I/O-related system calls. It has sometimes seemed inevitable that io_uring would, like many other parts of the kernel, gain BPF capabilities as a way of providing more flexibility to user space. That has not yet happened, but there are currently two patches sets under consideration that take different approaches to the problem.

[$] Debian debates amending architecture support stratagem

The Linux kernel supports a large number of architectures. Not all of those are supported by Linux distributions, but Debian does support many of them, officially or unofficially. On October 26, Bastian Blank opened a discussion about the minimum version of these architectures that Debian should support: in particular, raising the de-facto minimum versions in the next Debian release ("forky"). Thread participants were generally in favor of keeping support for older architecture variants, but didn't reach a firm conclusion.

Postmortem of the Xubuntu.org download site compromise

In mid-October, the Xubuntu download site was compromised and had directed users to a malicious zip file instead of the Torrent file that users expected. Elizabeth K. Joseph has published a postmortem of the incident, along with plans to avoid such a breach in the future: To be perfectly clear: this only impacted our website, and the torrent links provided there. If you downloaded or opened a file named "Xubuntu-Safe-Download.zip" from the Xubuntu downloads page during this period, you should assume it was malicious. We strongly recommend scanning your computer with a trusted antivirus or anti-malware solution and deleting the file immediately. Nothing on cdimages.ubuntu.com or any of the other official Ubuntu repositories was impacted, and our mirrors remained safe as long as they were also mirroring from official resources. None of the build systems, packages, or other components of Xubuntu itself were impacted.

Blender 5.0 released

Version 5.0 of the Blender animation system has been released. Notable improvements include improved color management, HDR capabilities, and a new storyboarding template. See the release notes for a lengthy list of new features and changes, and the bugfixes page for the 588 commits that fixed bugs in Blender 4.5 or older.

[$] The current state of Linux architecture support

There have been several recent announcements about Linux distributions changing the list of architectures they support, or adjusting how they build binaries for some versions of those architectures. Ubuntu introduced architecture variants, Fedora considered dropping support for i686 but reversed course after some pushback, and Debian developers have discussed raising its architecture baseline for the upcoming Debian 14 ("forky"). Linux supports a large number of architectures, and it's not always clear where or by whom they are used. With increasing concerns about diminishing support for legacy architectures, it's a good time to look at the overall state of architecture support on Linux.

[$] Pouring packages with Homebrew

The Homebrew project is an open-source package-management system that comes with a repository of useful packages for Linux and macOS. Even though Linux distributions have their own package management and repositories, Homebrew is often used to obtain software that is not available in a distribution's repository or to install more current versions of projects than are available from long-term-support (LTS) distributions. Homebrew 5.0.0, released on November 12, 2025, expanded Linux support to include 64-bit Arm packages in addition to x86_64, and turned on concurrent downloads by default to speed up package downloads.

Git 2.52.0 released

Version 2.52.0 of the Git source-code management system has been released. Changes include a new last-modified command to find the closest ancestor commit that touched one or more paths, a couple of git refs improvements, a new git repo command for obtaining information about the repository itself, and more. See the announcement and this GitHub blog entry for more information.

[$] Hot-page migration and specific-purpose NUMA nodes

For better or for worse, the NUMA node is the abstraction used by the kernel to keep track of different types of memory. How that abstraction is used, though, is still an active area of development. Two patch sets focused on this problem are currently under review; one addresses the perennial problem of promoting heavily used folios from slower to faster memory, while the other aims to improve the kernel's handling of nodes containing special memory installed for a specific purpose.

Josefsson: Introducing the Debian Libre Live Images

Debian developer Simon Josefsson has announced the Debian Libre Live Images project, to allow installing Debian without any non-free software: Since the 2022 decision on non-free firmware, the official images for bookworm and trixie contains non-free software. The Debian Libre Live Images project provides Live ISO images for Intel/AMD-compatible 64-bit x86 CPUs (amd64) built without any non-free software, suitable for running and installing Debian. The images are similar to the Debian Live Images distributed as Debian live images. He does warn that this is a first public release, so there may be problems. See the current list of known issues before trying the images out.
