One of the latest optimizations to the Mesa Vulkan drivers by Natalie Vock of Valve's Linux graphics team is faster and more vRAM efficient sorting for Morton code keys that are important for fast BVH construction and greater GPU parallelism...

Firefox has finally begun supporting Vulkan Video decoding to complement their long-used VA-API support on Linux. This is good news for the official NVIDIA Linux graphics driver stack as it's been the notable vendor not supporting the Video Acceleration API. But prior to Firefox rolling out its experimental Vulkan Video support, an independent implementation of VA-API built atop NVIDIA's NVDEC interface has been available for supporting GPU video acceleration in Firefox. That project is out today with its newest release...

With Linus Torvalds remarking in the Linux 7.3-rc1 release announcement of the AMD kernel graphics driver changes for amounting around a third of the -rc1 changes due to the big AMD GPU register files for DCN 6.0 and other new IP additions, here are some fresh code stats at large...

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...

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...

Canonical today published Ubuntu 26.04.1 LTS as their first point release in the long-term support series for the "Resolute Raccoon"...

Over the past year and a half a number of open-source drivers in the Linux kernel have been orphaned as a result of departures from the company. The impact has ranged from the Intel CPU "coretemp" temperature driver being orphaned without a maintainer to other lesser known Intel drivers. Another lesser known Intel driver is now being orphaned with no longer having a maintainer at the company: the Intel Specific Absorption Rate Driver...

It was back in May that the surprising event happened of AMD posting HDMI 2.1 FRL patches for their open-source AMDGPU Linux driver as part of their broader HDMI 2.1 bring-up. For years the open-source HDMI 2.1 support in AMDGPU was blocked by the HDMI Forum but whether it was due to Valve or some other event, the code was finally unblocked. While it's been part of the kernel since Linux 7.2, it's been disabled by default -- except that is now changing...

Following last week's main set of memory management "MM" related updates for Linux 7.3, another batch of MM code updates were submitted and merged today as we prepare to close out the Linux 7.3 merge window. There are a few optimization patches that stand out along with other mostly small fixes/changes...

Back in July ROCm 7.14 was announced as their new production release built atop TheRock build system and introducing Ryzen AI 400 series support. The versioning choice was a bit odd since ROCm 7.2 was the stable release at the time while ROCm 7.9+ turned into "tech preview" releases. With ROCm 7.14, it was declared stable. In clearing up that versioning mess, they have done a major version bump... to ROCm 10.0...

Earlier this week I showed off some of the very nice Btrfs performance gains on Linux 7.3. For those wondering what kernel optimizations may have carried over to other file-systems or other file-system specific enhancements, here are Linux 7.2 vs. 7.3 Git performance benchmarks across Btrfs, EXT4, F2FS, and XFS on the same system.

With the never-ending quest for greater I/O performance in the HPC space and the demands all the more relentless in the AI era, the Linux kernel block subsystem activity continues to be as vibrant as ever along with the ongoing innovations in the IO_uring space...
