In addition to the proposed Hierarchical Queued NUMA-aware spinlocks for better performance, another interesting performance-enhancing patch series posted in the past 24 hours for the Linux kernel is for improving the performance of single-threaded tasks running on high core count CPU desktops / workstations / servers.

We eagerly await to see if the AMD ISP4 driver will be ready for mainlining in the imminent Linux v6.19 merge window but it's getting down to the wire and thus looking less likely it will make it unless action is taken in the coming days. Today though a sixth version of this AMD ISP4 image signal processor driver was posted for this last piece of the puzzle in enabling the web camera on the HP ZBook Ultra G1a Strix Halo laptop as well as future Ryzen high-end laptops.

The NTFSPLUS Linux kernel driver as a modern NTFS file-system driver implementation continues quickly taking shape as it aims to become the most performant and feature-rich NTFS read/write driver for Linux systems.

A Huawei engineer has sent out patches proposing HQspinlock as a Hierarchical Queued NUMA-aware spinlock for the Linux kernel. HQspinlock aims to addresss inefficiencies within the Linux kernel's spinlock on modern NUMA-systems due to frequent and costly cross-NUMA cache-line transfers.

Vulkan 1.4.335 released a few hours ago as the latest iteration of this high performance graphics and compute API. With being just a week since the prior update and given the US Thanksgiving week, it's on the lighter side in terms of issues addressed. There is one new extension though and it's a big one: VK_EXT_present_timing is finally merged.

It's been two months since there were any notable Intel Linux engineering departures to note following various layoffs and voluntary departures this year that have unfortunately impacted their Linux/open-source talent. Sadly this US Thanksgiving is a new departure to note: one of Intel's maintainers for the Xe open-source Linux kernel graphics driver is leaving the company. This is for the modern Xe driver used by default since Lunar Lake and playing a pivotal role for Intel Linux graphics moving forward.

Following up on the discussion from earlier this month among GCC developers over switching to C++20 by default for the GCC compiler as the default C++ standard when not otherwise set, that change has indeed happened. Merged now is the change defaulting to C++20 (well, the GNU++20 dialect) rather than C++17/GNU++17 when not otherwise specified when compiling C++ code.

In addition to Intel Arrow Lake desktop performance evolving nicely on Linux over the course of 2025, the Intel Arc B-Series graphics that launched last December with the Arc B580 have evolved quite nicely too with their open-source driver stack. With it coming up on one year since the Arc B580 launch, here is a look at how the GPU compute performance has evolved since that point. Similar Intel Arc B580 Linux graphics comparisons are also coming up in a follow-up comparison on Phoronix.

Zlib-ng 2.3.1 is out today as the first stable release in the v2.3 series for this Zlib replacement that carries a variety of performance optimizations for speedier compression/decompression.

For those Linux desktop users in the US needing another reason to be thankful this Thanksgiving, a huge and long-awaited accomplishment is ready for merging to the kernel: the Color Pipeline API that is important for HDR is ready for merging! As of last night the code is queued in DRM-Misc-Next for this years-in-the-making effort.

Just a few days ago I wrote about the Glibc math code seeing a 4x improvement on AMD Zen by changing the used FMA implementation. Merged overnight was a new generic FMA implementation for the GNU C Library and now yielding up to a 12.9x throughput improvement on AMD Zen 3.

Canonical announced today the Ubuntu 26.04 "Resolute Raccoon" Snapshot 1 images as their first monthly ISO snapshots of the upcoming Ubuntu 26.04 LTS release.

Two years and one week since the prior point release, Common Desktop Environment 2.5.3 is now available as the latest iteration of this Unix desktop environment built around the Motif toolkit. CDE has been open-source for more than a decade now but its development not exactly brisk. But for those resisting the likes of Wayland and other modern display tech -- especially with KDE announcing today Plasma 6.8 will be Wayland-exclusive -- CDE 2.5.3 is now available.

Originally opened in September 2020 by NVIDIA Linux engineer James Jones, tonight the Vulkan VK_EXT_present_timing extension was finally merged! Five years in the making and incorporating contributions from Google, NVIDIA, AMD, Collabora, Samsung, Unity, and Red Hat is this prominent new addition to the Vulkan API.

With the great upstream support for AMD Radeon graphics in the Linux kernel and Mesa, most desktop users / gamers / enthusiasts are best off just using the latest code shipped by their distributions or via the enthusiast-supported third-party archives/repositories. But for those on older enterprise Linux distributions, Radeon Software for Linux 25.20.3 was recently released for shipping that packaged AMD Linux graphics driver stack. This 25.20 series is the big one where they are now officially supporting the Mesa RADV Vulkan driver in place of their own former Vulkan Linux driver.

Following the release of ROCm 7.1 from just under one month ago, ROCm 7.1.1 is now available with expanded Linux operating system support, continued Instinct MI350 series work, more large language models working on RDNA4 GPUs, and other enhancements.

It's been just over one year now since the launch of the Core Ultra 9 285K and other Arrow Lake desktop processors. For those that may be considering an Arrow Lake CPU this holiday season for a Linux desktop or just curious how the power and performance has evolved one year later, here are some leading-edge benchmarks of the Intel Core Ultra 9 285K compared to the launch-day performance last October.

KDE developers announced they are going "all-in on a Wayland future" and with the Plasma 6.8 desktop it will become Wayland-exclusive. The Plasma X11 session is going away.

A Fedora special interest group is being proposed to help improve production stability of Fedora Linux and better handling incident management when problems do arise.
