Red Hat's Peter Hutterer announced the release today of xkbcomp 1.5, the CLI utility used for compiling X Keyboard Extension (XBD) keyboard descriptions for the X.Org Server. Driving this new xkbcomp release are fixes for four security issues.

In addition to new AMD CPU features being merged today for Linux 6.19, there are also some new Intel CPU features that hit Linux Git today that are worth highlighting.

Linus Torvalds just merged another set of pull requests to Git for the in-development Linux 6.19 kernel. With the latest round of merges, there are two separate AMD changes worth highlighting.

Open-source firmware consulting firm 3mdeb published a blog post today outlining their work on bringing their Coreboot-downstream Dasharo to the ASRock Rack SPC741D8/2L2T, a recent server motherboard for supporting Intel Xeon Sapphire Rapids and Emerald Rapids processors.

An important set of patches were just merged a few minutes ago to Linux Git for the ongoing Linux 6.19 kernel with some important performance implications.

Merged as part of the objtool changes for the Linux 6.19 kernel is introducing the "klp-build" script as a new solution to generate livepatch modules using a source .patch file as the input. This klp-build effort was spearheaded by Josh Poimboeuf with ideas learned from the out-of-tree Kpatch project over the past decade.

TornadoVM 2.0 is out today as the newest feature release for this OpenJDK and GraalVM plug-in that allows Java programs to run on heterogeneous hardware. TornadoVM targets continue to be OpenCL, NVIDIA PTX, and SPIR-V compatible devices for a range of accelerator support for use from conventional Java code.

Linux has maintained a default 4MB minimum writeback chunk size but with the in-development Linux 6.19 kernel it will allow file-systems to override that minimum value. This in turn can help avoid fragmentation and yield a better experience for zoned rotation media and other uses.

NVIDIA today released the 590.44.01 Linux driver build as the first beta of their R590 series driver branch for Linux customers.

Evidently Canonical has been pretty pleased with the uptake of Ubuntu on Microsoft's Windows Subsystem for Linux (WSL2) within enterprise/corporate environments as they are now offering Ubuntu Pro for WSL.

Via the openSUSE Innovator Initiative, packaging of the Intel Neural Processing Unit (NPU) driver for the openSUSE ecosystem has begun. This is helping to jump-start the Intel NPU support within the openSUSE space although user-space applications ready to leverage the Intel NPU still remains very limited.

The big set of kernel scheduler changes were merged on Monday for the in-development Linux 6.19 kernel.

Merged yesterday for the Linux 6.19 kernel were "substantial" improvements to the kernel's credential infrastructure to provide guard-based management that allows for kernel code simplification and avoiding manual reference counting across many subsystems.

The Steam Survey results are out for November 2025 and continue to be very positive for the growing adoption of Linux gaming thanks to the success of the Steam Deck, the underlying Steam Play (Proton) software, and now further excitement thanks to the upcoming Steam Machine and Steam Frame.

FreeBSD 15.0 is officially released as the newest major update to this leading BSD operating system.

SUSE engineer David Sterba submitted the Btrfs pull request for Linux 6.19 on Friday, ahead of the Linux 6.18 stable kernel release that took place on Sunday. This copy-on-write file-system continues seeing some enticing feature work and other improvements for this next version of the Linux kernel.

Fedora stakeholders have been eyeing a nicer experience for NTSYNC usage with Wine and Steam Play by being able to have the NTSYNC kernel module load when it's likely to be used. That approval has now been granted by the Fedora Engineering and Steering Committee (FESCo) for the Fedora 44 release.

When it comes to AMD Radeon/Instinct GPU compiler support much of the emphasis is on the LLVM/Clang compiler stack with their official AMDGPU LLVM shader compiler back-end as well as having the AOMP downstream compiler fork and the like. But the GNU Compiler Collection "GCC" does continue allow targeting AMD GPU targeting with its "AMDGCN" back-end and using the likes of the OpenMP API. It's not too often seeing new AMD GPU activity there for GCC but merged today is now support for managed memory.

While some Linux distributions have begun establishing AI policies, we haven't seen any communicated from the Ubuntu camp yet but will apparently be permitted at least for project infrastructure. AI is being used currently in an effort to help modernize the Ubuntu Error Tracker.

Miguel Ojeda has already submitted the core Rust programming language infrastructure updates intended for the Linux 6.19 merge window. In the pull request he also notes that moving forward the minimum supported Rust version for compiling the Linux kernel will likely follow whatever the minimum Rust version currently in use by the latest Debian stable release.
