A low-level Linux kernel improvement being worked on by engineers at Amazon Web Services (AWS) is for introducing a PCI Configuration Space Cache "PCSC" to help with dense SR-IOV deployments that can end up hitting significant overhead with the current Linux kernel.

Linux Mint Debian Edition 7 is officially out today as the latest version of this Linux Mint distribution based on upstream Debian rather than Ubuntu.

Even prior to the recent ending of the Linux 6.18 merge window and its many new features, the first "drm-misc-next" pull request of new material intended for Linux 6.19 was already submitted for inclusion to DRM-Next.

Canonical is looking to eliminate use of its Ubuntu ISO Tracker that has been relied on the past 15+ years and in turn 30+ releases. Their ISO Tracker has grown unreliable and difficult to maintain. But without any proper solution ready, for Ubuntu 26.04 LTS the ISO Tracker may be replaced by a temporary spreadsheet and Discourse thread.

Last month Arm announced the Lumex CSS platform with C1 CPUs and Mali G1 GPUs. One month later, Arm is already beginning to open-source graphics driver patches for enabling the new Mali-G1 graphics processor.

The BeOS-inspired Haiku operating system has published their September 2025 progress report to outline recent work on this open-source OS.

It's been one year already since Intel and AMD formed the x86 Ecosystem Advisory Group in cooperation with other industry stakeholders. Today both companies are marking the first anniversary while reaffirming their commitment to the group.

Problematic code dating back to 2017 has now been reverted within the Intel open-source Mesa driver code that led to various games having rendering/corruption issues as well as various hangs and crashes in other games. This affected a variety of Intel graphics hardware and software while now has finally been tracked down with the problematic code removed. This is a big improvement for Linux gamers on Intel graphics.

A big patch series was posted today for the Linux kernel that would allow enabling/disabling CPU security mitigations at run-time rather than the current handling that can only be managed at boot-time via various Linux kernel command-line arguments. Thus due to changing security needs, differing workloads mandating different CPU security concerns and the like, this proposed feature would allow Spectre, Meltdown, and other CPU security mitigations to all be toggled at run-time.

While more code enabling Apple Silicon is reaching the mainline Linux kernel, a lot of important functionality so far remains under development or out-of-tree in the downstream Asahi Linux repository. One piece that's quite important for modern computing and still working its way to the mainline kernel is enabling USB3 functionality with Apple Silicon devices on Linux.

Now that the Linux 6.18 merge window is over with Linux 6.18-rc1 having released yesterday, here is a look at all the interesting new features and changes to find with this kernel. Making Linux 6.18 all the more exciting is that it's expected to become the 2025 Linux LTS kernel once its stable release occurs in December.

Mir 2.23 is out today as the newest version of this Canonical-led library for crafting Wayland-based shells and for smaller desktops to ease the adoption of Wayland, with a focus on Ubuntu Linux platforms.

In the works the past number of months has been cache-aware load balancing / cache aware scheduling support for Linux. The latest iteration of those patches by Intel were posted this weekend and are enjoying the most uplift on AMD EPYC Genoa and newer platforms.

Box64 0.3.8 is now available for this x86_64 user-space emulator for Linux that allows ARM64 and RISC-V 64-bit and LoongArch 64-bit systems to enjoy running x86_64 games and applications. Box64 along with the likes of FEX-Emu are the leading options for those needing to run x86_64 programs on ARM64 and elsewhere.

One year ago updated Intel documentation noted AMX-TRANSPOSE as one of the new ISA additions for Diamond Rapids. But in updated Intel architecture documentation last month, it oddly removed all references to AMX-TRANSPOSE. Confirming that the Advanced Matrix Extensions (AMX) addition for TRANSPOSE is now dead, an Intel engineer posted a patch to remove AMX-TRANSPOSE from the GCC compiler.

The ReactOS project that continues striving toward being an "open-source Windows" ABI compatible operating system has been seeing some activity recently around supporting Windows Display Driver Model (WDDM) display drivers as the newer evolution of XDDM drivers.

With last month's GNOME 49 release, the 32-bit Compatibility extension for the GNOME Flatpak Runtime is no more. This is part of the broader effort of phasing out 32-bit support.

As part of Blender continuing to build out the Vulkan API capabilities for this open-source 3D modeling software, a proof of concept merge request was opened for beginning to make use of Vulkan ray queries.

Linux 6.18-rc1 is now available for testing with the Linux 6.18 merge window closed. Linux 6.18 will be out in December and is anticipated to become this year's Linux LTS kernel version.

Well, here is a weekend surprise... Red Hat engineer and Rusticl lead developer Karol Herbst has opened a Mesa merge request for "CLUDA" as a compute-only driver that implements the Gallium3D API atop the NVIDIA CUDA driver API. Wow.
