Last October I highlighted an interesting post on the Linux kernel mailing list around an x86 corporate entity other than Intel or AMD that left mysterious intrigue. The developer that detailed those x86 opcode/CPUID/MSR allocations back in July then detailed 16-tile and 32-tile AMX implementations again for something outside the current scope of Intel/AMD processors. Today another message is being relayed from that "corporate entity other than Intel/AMD."

In addition to the Union QtWidgets initial release happening this week, a number of other improvements also landed in the past few days in making Plasma 6.8 all the more exciting.

ReactOS 0.4.16 released today as the newest major update to this "open-source Windows" project providing an open-source OS with Windows driver and application compatibility.

Coming in as a late pull request ahead of the Linux 7.3 merge window closing this weekend were the Flash Friendly File-System (F2FS) updates that have now made it into Linux Git.

This week was extremely eventful in the GNOME space with GPU reset recovery for GNOME Mutter now largely wrapped up and the merge request opened to facilitate the code review. There was also the announcement of the half million Euro Sovereign Tech Agency investment into Flatpak. Plus on the application side were a few more interesting advancements this week.'

As an update to the May story about California's age verification law may end up exempting most Linux distributions, that AB-1856 bill has finally passed!

In time for the weekend Linux gamers, Valve last night released the first preview of SteamOS 3.9 for the Steam Deck, Steam Machine, and other devices. This early preview comes with some exciting software updates.

The Unsorted Block Images "UBI" layer in the Linux kernel for NAND flash memory tracking and wear leveling finally has the notion of per-device wear-leveling thresholds.

The voting is over and there is a winner now known in the much-debated Debian General Resolution voting over an AI policy for the Linux distribution.

Premiering in KDE Plasma 6.7 was Union as the new CSS-based style/theming engine for Plasma. Union ultimately aims to address KDE's fragmented ways of styling apps. As a step closer to that goal, there is now the initial release of Union for QtWidgets support.

The Trusted Platform Module (TPM) subsystem changes for the Linux 7.3 kernel are centered around code clean-ups and improvements being made as a precursor toward TrenchBoot support.

DXVK 3.1 is out today as the newest feature release for this Direct3D 8 / 9 / 10 / 11 implementation built atop the Vulkan API as a key component to Valve's Steam Play (Proton).

The past month I have been testing out the HP Z4 G6i workstation across many different workloads and grueling tasks. This HP workstation powered by the Intel Xeon 600 series "Granite Rapids WS" and NVIDIA RTX graphics offers a lot of compute power, but with the top-end configuration retailing for over $41k USD is quite pricey in today's environment. Windows 11 Pro is the default operating system of the HP Z4 Gi but Ubuntu LTS releases are supported and it's "Linux-ready" at large.

With the proliferation of AI/LLM models analyzing the Linux kernel's vast codebase, there has been a surge in the number of CVEs per kernel release. After typically being around 500 CVEs fixed per release, we are now approaching 2,000 CVEs fixed per release and perhaps will break that threshold for Linux 7.3.

Google Summer of Code 2026 featured a project working on GPU reset recovery for GNOME's Mutter compositor. GSoC has now wrapped up and the project overall was largely successful although some outstanding work remains. In this last week the merge request has been opened to conduct code review on this GPU reset recovery implementation for GNOME.

The Khronos Group is closing out the month of August with the Vulkan 1.4.361 specification update.

Longtime Linux kernel developer Chris Mason is departing Meta. In the process of doing so, he is also stepping down from his co-maintainership role of the Btrfs file-system.

The USB and Thunderbolt changes have been merged for Linux 7.3. Two changes stand out for me in the USB subsystem code with Linux 7.3. First, the kernel arguably being long overdue for checking USB-C cables capabilities whether they support alt-modes. Second, a new low-latency USB4STREAM option for lower latency data transfers between USB4-connected systems.

The char/misc changes were merged this week for the Linux 7.3 cycle. While there is a lot of IIO driver churn as usual and updates to the likes of the Google Binder drivers, there continues to be the 2026 trend of removing old hardware drivers that are rarely updated these days and likely have no active users left on the mainline Linux kernel. This trend is further pushed along by the surplus of AI/LLM-generated bug reports and patches these days causing additional maintenance burden for these obsolete drivers.

The latest beneficiary of Germany's Sovereign Tech Agency is Flatpak where more than half a million Euros will be invested over the next two years to help with app sandboxing and other functionality.
