As part of the various end-of-year benchmarking comparisons on Phoronix and with Linux 6.19 switching older AMD GCN 1.0/1.1 graphics cards to the AMDGPU driver by default, I planned for a very large AMD Radeon graphics card comparison on the latest open-source Linux driver for ending out 2025. In the end though I was thwarted by newer AMD RDNA3 / RDNA4 graphics cards regressing hard on Linux 6.19 that led to ending this testing prematurely due to a show-stopping bug. In any case in this article offers a fresh look at older GCN and RDNA graphics cards on Linux 6.19 + Mesa 26.0-devel.

Coreboot 25.12 is out today as the latest quarterly feature update to this open-source BIOS/firmware solution...

It was a very interesting year for Ubuntu Linux. Ahead of the important Ubuntu 26.04 LTS release due out this coming April, Ubuntu Linux this year was expeditiously migrating to new Rust-based system tools like sudo-rs and Rust Coreutils, new performance optimizations continued to be explored for bettering the out-of-the-box Ubuntu performance, better ARM64 support with its desktop ISO, and enhancing the Snapdragon X Elite laptop support were among the Ubuntu highlights in 2025...

An exciting post-Christmas patch series out on the Linux kernel mailing list this morning is proposing a new runtime standby ABI that is similar in nature to the "Modern Standby" functionality found with Microsoft Windows...

This year there was a lot of going on in the NVIDIA Linux world from their official driver stack seeing better Wayland support to a lot on the open-source scene from NVIDIA engineers contributing a lot directly to the Rust-based Nova open-source driver that continues taking shape, the Mesa NVK Vulkan driver becoming more performant and capable, and a lot of other happenings. Here is a look back at the most popular NVIDIA content of 2025 on Phoronix...

For those using Microsoft's exFAT file-system under Linux for the likes of flash drives and SD cards, a new patch series posted today aims to enhance the read performance. The new patches are shown to improve performance by about 10% while also having lower overhead...

The Arch Linux based CachyOS has been quite popular with Linux gamers and enthusiasts for offering leading out-of-the-box performance, especially following the shutdown of Intel's Clear Linux. CachyOS has developed quite a following on the Linux desktop while looking ahead to 2026 they will be working on a server edition...

As a wonderful Christmas gift to open-source fans, NVIDIA dropped their proprietary license on the CUDA Tile intermediate representation and has now made the IR open-source software...

One of the pleasant surprises this year was AMD ending the AMDVLK driver development with AMD dropping their proprietary OpenGL and Vulkan driver components on Linux at long last for their Radeon Software for Linux packages. This was arguably long overdue with enthusiasts and Linux gamers long preferring the RadeonSI+RADV Mesa drivers and those drivers even doing very well in recent years for workstation graphics workloads. One of the areas where AMDVLK formerly delivered better performance than RADV was with Vulkan ray-tracing. But RADV ray-tracing improved a lot in 2025 as shown in recent benchmarks. So for this Christmas 2025 benchmarking is a final look at how RADV is going up against the now-defunct AMDVLK driver.

The Linux 6.19 kernel has been a bit bumpy in the scheduler department but at least one fix is on the way for addressing fallout...

For X11/X.Org fans there is a new Christmas surprise: Phoenix as an in-development X Server written from scratch using the Zig programming language...

When it came to the most viewed AMD Linux/open-source news of 2025 there were a lot of accomplishments for the company this year both on the CPU and graphics side of the house and from consumer to server hardware. Today is a look back at the most popular Intel open-source/Linux news of the year, which unfortunately, their layoffs and other cuts to their software engineering were attracting a lot of interest...

Google's Propeller is a profile-guided, reflinking optimizer for large codebases. Propeller is built atop LLVM and can allow for whole-program optimizations. Google compiler engineers are now hoping to bring the Propeller tool into the upstream LLVM codebase...

The mainline Linux kernel already supports several different Mobileye SoCs for that company focused on self-driving tech and advanced driver assistance systems (ADAS). Consulting firm Bootlin has been working on bringing their latest SoC, the Mobileye Eyeq6Lplus, to the mainline Linux kernel...

The past several years we have seen new releases of the Ruby programming language implementation for Christmas (25 December). This year is no different with Ruby 4.0 having been released this morning...

Libreboot as the Coreboot downstream focused on free, open-source boot firmware is out with a new test release for Christmas...

As a wonderful gift to open-source Linux virtualization users this Christmas Eve is the release of the QEMU 10.2 emulator...

As part of my various end-of-year benchmarking comparison articles for looking at the performance evolution of Linux is a fresh look at the Qualcomm Snapdragon X Elite laptop experience when using Ubuntu 25.10 with the latest X1E Concept packages, which includes taking the X1 Elite optimized kernel to the latest Linux 6.18 stable series. Unfortunately, there are significant performance regressions observed compared to a few months ago that just make AMD Ryzen AI and Intel Core Ultra laptops a better choice for Linux laptop users.

One of the interesting open-source projects to come about this year was Wayback as an X11 compatibility layer using Wayland. Wayback could be used by default on Alpine Linux next year among other distributions. For ending out 2025 development, Wayback 0.3 is now available...

As part of our various "year end" articles, here is a look back at the most popular AMD Linux/open-source news and hardware reviews of 2025...

The next kernel cycle that will be known as either Linux 6.20 or Linux 7.0 depending upon how Linus Torvalds handles the versioning for this next x.20 milestone. More than likely it will be Linux 7.0 given his historical versioning scheme, but whatever the case, ahead of this next kernel cycle some initialization changes for the CXL subsystem are building up...

In LLVM Git yesterday for next year's LLVM 22 release the Qualcomm Xqci RISC-V vendor extension is no longer deemed experimental...

One of the features being worked on for a while with the read-only EROFS file-system is page cache sharing. Besides EROFS being popular on some mobile/embedded devices, this open-source read-only file-system has been quite popular for container usage and there this page cache sharing functionality can provide some significant reductions in RAM usage...

An unfortunate Linux kernel bug coming to light just ahead of Christmas may cause frustration for some server administrators, particularly public cloud providers... It turns out with the Linux kernel releases since 2022, KVM guest virtual machines making use of Intel Advanced Matrix Extensions (AMX) is possible to cause the host to experience a kernel panic...
