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.

Sched_ext as the extensible scheduler code for the Linux kernel that allows loading schedulers from user-space via eBPF code has shown a lot of interesting possibilities. Andrea Righi of NVIDIA who has been heavily involved in sched_ext development shared some of the future plans being looked at as we move into 2026.

If Linux 6.19 switching from the Radeon legacy to AMDGPU kernel drivers for the GCN 1.0/1.1 GPUs for those ~13 year old GPUs isn't nostalgic enough for you, here's something a bit more nostalgic this holiday season: fresh open-source driver commits to the Radeon R300g driver for supporting those 23 year old ATI R300 GPUs up through the 20 year old R500 class graphics processors.

With the upcoming LibreOffice 26.2 open-source office suite release, they are getting rid of the "Community Edition" branding for the standard version of this widely-used cross-platform office suite.

Very talented open-source developer Fabrice Bellard who already is well known for his work on QEMU, the Tiny C Compiler, and FFmpeg, has another accomplishment: Micro QuickJS. The Micro QuickJS JavaScript engine can compile and run JavaScript programs with as little as 10 kB of RAM.

Ahead of Intel Panther Lake laptops expected to debut next month at CES in Las Vegas, the Linux driver support for the next-gen "50xx" NPU of Panther Lake is now complete. The last piece of the driver support puzzle is now in place with the NPU firmware binaries having been upstreamed today to the linux-firmware.git repository.

As an end-of-year tradition at Phoronix for running a lot of year-over-year comparison performance benchmarks and other long-term performance evaluations, it's typically done on the higher-end hardware. That's done for a matter of time savings with maximum performance when running often 100~200+ benchmarks per article, the highest-end hardware typically being the most interesting in terms of features and capabilities, and more often than not getting flagship hardware review samples as opposed to the lower-end hardware. There have been benchmarks recently showing the big gains for AMD EPYC from a one year Linux LTS kernel upgrade, Intel Granite Rapids over the past year, and even the AMD Milan-X performance over the last four years, among other end-of-year 2025 articles. Today is a look at how the AMD Ryzen AI 5 "Krackan Point" CPU/iGPU performance has evolved simply over the last six months. It was a rather surprising twist how much better the Linux performance is over simply the past six months.

Merged ahead of the upcoming GCC 16.1 stable release of the GCC 16 compiler is initial support for the Armv9.6-A target.

The open-source Mesa PowerVR "PVR" Vulkan driver has merged multi-architecture support as part of preparing to add support for newer Imagination GPUs.

Last week a request for comments (RFC) was issued around establishing an LLVM AI Tool Use Policy. The proposed policy would allow AI-assisted contributions to be made to this open-source compiler codebase but that there would need to be a "human in the loop" and the contributor versed enough to be able to answer questions during code review. Separately, yesterday a proposal was sent out for creating an AI-assisted fixer bot to help with Bazel build system breakage.

An interesting anecdote from this month's Linux Plumbers Conference in Tokyo is that Meta (Facebook) is using the Linux scheduler originally designed for the needs of Valve's Steam Deck... On Meta Servers. Meta has found that the scheduler can actually adapt and work very well on the hyperscaler's large servers.

For those currently owning an ASUS ROG MAXIMUS X HERO or ASUS Pro WS TRX50-SAGE WIFI A motherboard, Linux sensor monitoring support will be in place for the next kernel release.
