Fedora 43 is working its way toward release in the coming weeks and is now going through a very late change. A change was announced and accepted today for increasing the size of the /boot partition. This is driven by the ever-increasing number of firmware files needed for different devices to function under Linux with open-source drivers. A large motivator to this change was the very large and growing NVIDIA GPU firmware file sizes for Nouveau and the future Nova driver.

The NFS server (NFSD) improvements were merged today for the Linux 6.18 kernel. Most exciting is a new experimental feature that can help with scaling NFSD both for low-end/low-cost servers up through high-end larger server platforms.

A patch series posted today for Nouveau, the open-source NVIDIA kernel driver within the mainline Linux tree, can help overcome some performance obstacles currently observed with the Mesa NVK Vulkan driver.

The PCI subsystem updates were merged today for the in-development Linux 6.18 kernel. The PCI changes this cycle are mostly a random assortment of different changes to the wide assortment of PCIe drivers. Standing out is a workaround for dealing with a possible PCI Express performance issue for latest-generation Xeon 6 servers.

The Rust-written Redox operating system written from scratch is now enabling multi-threaded support by default for x86-based systems.

Ubuntu 25.10 is looking quite nice in the performance department ahead of its official release later this week. On various systems tested thus far, Ubuntu 25.10 is delivering nice gains over Ubuntu 25.04 and compared to the current Ubuntu 24.04 LTS. The latest Ubuntu 25.10 benchmarking at Phoronix is looking at the Intel Core Ultra Lunar Lake performance using the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition laptop.

While the Intel In-Memory Analytics Accelerator (IAA) so far is just found on newer Xeon server processors, prior Linux patches acknowledge IAA being found on at least select Panther Lake SoCs. New patches ready for merging to the Linux 6.18 kernel are indicating IAA accelerator(s) will also be found on at least some of the lower-cost Wildcat Lake SoCs too.

The networking subsytem updates for Linux 6.18 have been merged. There is a lot of enticing performance optimizations in different areas of the networking stack for this new kernel. Plus new wired and wireless networking hardware support and other improvements to get excited about for this LTS kernel version.

At the start of the year, a new GCC compiler front-end was proposed for the half-century old ALGOL 68 programming language. Not exactly a popular programming language in recent decades and ahead of the GCC 15 release it was decided to not merge it yet to GCC. Even with that setback, development on the ALGOL 68 GCC compiler continues.

The x86 platform drivers area of the Linux kernel continues to see a lot of code churn for supporting new laptops and enhancing support for existing laptop models. Plus the likes of AMD PMF and Intel PMC continue to see ongoing improvements too.

The Intel Trust Domain Extensions (TDX) updates for the Linux 6.18 kernel allow it to work with Kexec for being able to load and boot into a new kernel from another currently running kernel.

The VFIO subsystem updates were merged last week for the ongoing Linux 6.18 merge window.

FreeBSD 15.0 continues working its way toward a stable release in early December and out today is the fifth alpha release.

Adding to the Linux storage/file-system excitement for Linux 6.18 is enhancements to some of the core FUSE code for supporting file-systems in user-space.

The past several months has seen AMD engineers working on a new RDMA driver for Ionic hardware through which they acquired Pensando a few years ago. That AMD-Pensando Ionic RDMA driver is now part of the upstream Linux 6.18 kernel.

The Direct Rendering Manager "DRM" pull request ended up leading to Linus Torvalds complaining over text and Rust code formatting but in the end he pulled all of these kernel graphics driver updates and also the associated "accel" accelerator subsystem drivers too.

Next year's GCC 16 compiler release is continuing the trend of enhancing the compiler diagnostics support, including new features like optionally outputting compiler error/warning diagnostics to HTML format for better analysis.

The HID changes have been merged for Linux 6.18 and are headlined by initial support in the mainline kernel for haptic touchpad handling.

For benefiting container usage on Linux, support for case-folding / case insensitive files and folder support has been added to OverlayFS.

All of the crypto subsystem changes have been merged for the in-development Linux 6.18 kernel.
