Merged today ahead of the Linux 6.18-rc5 kernel due out on Sunday is a partial fix for a performance regression observed on IBM POWER hardware.

Ryzen AI Software as AMD's collection of tools and libraries for AI inferencing on AMD Ryzen AI class PCs has Linux support with its newest point release. Though this "early access" Linux support is restricted to registered AMD customers.

AMD has begun their open-source compiler enablement upstreaming effort for Zen 6 processors! The first "Znver6" patch was sent out on Friday in preparing for new instructions to be found with these next-generation AMD Ryzen and EPYC processors.

Released one Friday was the newest version of oneDNN as this library started off by Intel and now officially under the UXL Foundation umbrella for serving as building blocks for deep learning software.

On ACPI-enabled systems Linux users can enjoy PCIe M.2 connected peripherals that "just work" without any extra fuss. But for those relying on Device Tree (DT) handling by the kernel, new patches from Qualcomm are working on representing PCIe M.2 connectors within DT files.

The Qt toolkit has merged support for Wayland's color-management-v1 protocol to replace the former xx-color-management-v4 protocol shipped by this open-source toolkit. The change was merged for Qt 6.11 development but also back-ported for the Qt 6.10 series.

KDE developers were off to a busy start for the month of November. A lot of feature activity continues happening for Plasma 6.6 while a lot of bug fixing is still going on for Plasma 6.5 and related KDE components.

FreeBSD 15.0-RC1 had been expected this weekend but instead a fifth beta release of FreeBSD 15.0 was deemed warranted.

In addition to GNOME's Mutter compositor removing its X11 back-end support to focus exclusively on Wayland while keeping around XWayland client support, another notable GNOME change this week was the GTK toolkit adding a "reduced motion" accessibility option.

It's been a while since having anything major to talk about with the NILFS2 file-system but it looks like that could be changing. NILFS2 as a reminder is a log-structured file-system with continuous snapshotting with its NILFS predecessor having been in the mainline kernel for two decades since the mid Linux 2.6 days.

Mesa 25.3-rc4 is available for testing as the latest weekly candidate as we work toward the Mesa 25.3 stable release this month.

Hyprland 0.52 is available today as the latest feature update for this alternative Wayland compositor.

It has been two years already since the Linux Containers project forked Canonical's LXD project as Incus. Now joining the Incus family is IncusOS as an immutable Linux OS built atop a Debian base with OpenZFS file-system support and designed around running containers with Incus.

DXVK is an important piece of Steam Play (Proton) that over time expanded to supporting Direct3D 9 / 10 / 11 and even D3D8 too. Meanwhile VKD3D-Proton delivers Direct3D 12 atop Vulkan. Now there is a fork of the DXVK project working to bring Direct3D 7 support atop Vulkan.

Posted last month were new Linux kernel scheduler-related patches rewriting the MM CID management code. The main takeaway for end-users from this set of 19 Linux kernel patches from an Intel engineer was seeing 14~18% improvement in a PostgreSQL database benchmark but that more benchmarks were needed. Curiosity got the best of me and I recently tested these patches on an AMD EPYC server to seeing some very enticing results for this in-development code.

New code likely to be submitted for the upcoming Linux 6.19 kernel would introduce ML-DSA/Dilithium post-quantum cryptography to be initially used for dealing with kernel module signing.

A new driver planned to be sent to the mainline Linux kernel for the upcoming Linux 6.19 merge window is yet another new contribution from Microsoft.

Vulkan 1.4.332 is out today as the latest weekly update to this high performance graphics and compute API specification. Besides a number of documentation clarifications/corrections, there is one new extension this week in the name of AI / machine learning.

Merged overnight to Mesa 26.0-devel and likely to be back-ported for the upcoming Mesa 25.3 release are a few fixes around high dynamic range (HDR) support within the common Vulkan windowing system integration (WSI) / display code.

Last week Canonical announced Ubuntu "architecture variants" with initially supporting "amd64v3" optimized packages built using the x86_64-v3 micro-architecture feature level. For this initial debut in the Ubuntu 25.10 archive an initial subset of packages are built using that higher feature level that can assume AVX/AVX2 and other more recent CPU ISA additions. More details on that and some initial desktop benchmarks can be found within the Ubuntu 25.10 amd64v3 Benchmarks article. Complementing that are some Ubuntu Server 25.10 benchmarks carried out on an AMD EPYC "Turin" server of the base amd64 packages versus amd64v3.
