Five years after releasing Lua 5.4, Lua 5.5 debuted today as the newest version of this lightweight and embeddable scripting language.

For those still using old AMD GCN 1.0 "Southern Islands" or GCN 1.1 "Sea Islands" graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy "Radeon" DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance benefit of now AMDGPU being the default as well as now enabling RADV Vulkan support out-of-the-box.

University researchers presented Rex at this month's Linux Plumbers Conference 2025 in Tokyo. Rex is designed for "safe and usable" Rust-based kernel extensions that could serve in place of eBPF programs for extending the Linux kernel functionality.

The upcoming Linux 7.0 kernel (unless it ends up being called Linux 6.20) will drop support for the AMD NPU2 as their second-generation neural processing unit that never ended up being released into any retail products.

NVIDIA engineer Igor Stoppa presented at the Linux Plumbers Conference (LPC) earlier this month around using Linux in safety-critical environments like automobiles and the current shortcomings of the upstream Linux kernel and the challenges on achieving Automotive Safety Integrity Level (ASIL) certifications around the Linux kernel. It's an interesting read/watch around the safety of Linux (or not) for such strict safety environments.

After being delayed by three months to allow additional time for new features to land, Weston 15.0 Alpha 1 is out today as a big feature release for this reference Wayland compositor.

Intel engineers as part of the OPEA Project today released the Generative AI Examples v1.5 update. This "GenAIExamples" open-source project is a collection of GenAI examples as part of showing the capabilities of the Open Platform for Enterprise AI (OPEA) and also highlighting Intel's hardware strengths for generative AI.

Intel today released libva 2.23 as the newest feature release for this Video Acceleration API "VA-API" reference library implementation. Most significant with libva 2.23 is adding AV1 Profile 2 support.

The second weekly release candidate of Linux 6.19 is now available for testing in leading up to the stable release in early February.

MPV 0.41 is out today as the newest feature release for this MPlayer/mplayer2-derived open-source video player. With MPV 0.41 there is a big focus on improving Wayland support as well as now preferring Vulkan Video acceleration over alternative video decode APIs.

One of the features that sadly didn't make it into the recent Linux 6.19 merge window was the long-awaited AMD ISP4 driver for supporting the web camera found with the high-end HP ZBook Ultra G1a and also expected to be used by future flagship AMD Ryzen laptops.

Since Linux 6.16 the Intel APX support has been ready for the kernel infrastructure and goes along with the compiler toolchain support for Advanced Performance Extensions with the likes of GCC and LLVM/Clang. The latest element being worked on for APX enablement in the open-source/Linux world is for allowing KVM guest virtual machines (VMs) to make use of APX.

Most notable with the input subsystem updates sent out today ahead of the Linux 6.19-rc2 release is some new hardware support. New this week is adding support for CRKD Guitars for those into musical gaming/apps.

Open-source developer Armin Wolf has been working most recently on marshalling support for the Windows Management Instrumentation (WMI) platform code within the Linux kernel. This WMI marshalling support is to better match the behavior of Microsoft Windows' WMI ACPI driver and ultimately to allow for better compatibility with some ACPI firmware and enhancing some WMI drivers.

It's not often getting to talk about hard drives on Phoronix these days, but there's an important fix merged to the Linux 6.19 kernel today ahead of Linux 6.19-rc2. If you happen to be using a Seagate ST2000DM008 Barracuda 2TB HDD, an important fix was merged to avoid it taking down the systems' SATA bus and/or potentially other issues.

Darktable 5.4 is out today as the newest feature release to this open-source RAW photography software. Besides improving camera support, UI enhancements, and more the Wayland support has been improved with Darktable. With today's Darktable 5.4 release, the Wayland support should be on par with the X11 support.

The Swedish VPN service Mullvad announced this week GotaTun, an open-source Rust-based WireGuard implementation that is forked from Cloudflare's BoringTun.

In addition to this week's drm-intel-next pull request to DRM-Next adding Nova Lake display support, a drm-xe-next pull request was also sent out on Friday that prepares a new multi-queue feature for Xe3P_XPC -- initially just the "Crescent Island" AI inference accelerator card. Plus other new features too for this Xe kernel driver in the upcoming Linux 7.0~6.20 kernel version.

With the Arch Linux packages for the NVIDIA official graphics driver moving to the now-stable NVIDIA 590 driver series that drops the GeForce GTX 900 and GTX 1000 series GPU support, Arch Linux users with those old Maxwell and Pascal graphics cards will need to transition to using the NVIDIA legacy driver packages from the Arch Linux AUR. Meanwhile for those on Turing and newer with the NVIDIA 590 driver will enjoy the open-source kernel modules by default being used.

The GNU Debugger "GDB" 17.1 is out today with a number of new features for enhancing the open-source debugging experience.
