AMDGPU kernel driver maintainer Alex Deucher of AMD sent out a set of 30 patches today working on clearing out all of the BUG() usage within this Linux kernel graphics driver.

That didn't take long... Mere minutes after NVIDIA confirmed some basic Rosa CPU details and its "Rigel" CPU core, merged to the upstream GNU Compiler Collection (GCC) codebase is initial enablement on the NVIDIA Rigel core.

Razer is a brand synonymous with gaming and finally in 2026 they are in the process of certifying their first laptop for Ubuntu Linux. This laptop going through Ubuntu Linux certification is the Razer Blade 18 RZ09-0582 and it offers incredible performance with the Core Ultra 9 290HX Plus processor and GeForce RTX 5090 graphics but with that also comes a very high price tag.

In a blog post today talking up the single threaded CPU performance of their Vera CPU with Olympus cores, NVIDIA confirmed a few basic details of their next-gen Rosa CPU featuring their "Rigel" core.

NVIDIA today published their latest stable driver update for Linux customers in their newest R610 release branch.

Bavarian Linux PC vendor TUXEDO Computers announced they are switching from Ubuntu to Debian as the base for their TUXEDO OS platform.

The Linux kernel's AF_ALG interface was deprecated in Linux 7.2. This interface for letting user-space programs interact directly with the Linux kernel crypto API has proven to be a "massive attack surface" due to a variety of security concerns. With its deprecation in Linux 7.2, some AF_ALG features are already removed and for Linux 7.3 this interface is being further restrained.

One of the original developers behind the work to allow the Linux kernel to be compiled using LLVM/Clang as an alternative to the GCC compiler is now back in the saddle working on LLVM Linux support. LLVM/Clang support for building the Linux kernel has been important for improving code portability and addressing GCC'isms, making use of LLVM compiler features not yet found with the GNU toolchain, evaluating the performance between GCC and Clang, and all the more important these days with the Linux kernel Rust integration.

In 2026 it's not too surprising when seeing old PCMCIA and ISA drivers being removed from the mainline Linux kernel source tree and old very low-speed network interfaces, with arguably the most surprising fast being how long they lasted in the mainline kernel. Meanwhile for the upcoming Linux 7.3 kernel, one of the first 10Gb Ethernet drivers is already set for retirement from the mainline Linux kernel.

The newest, unexpected addition to the Mesa codebase by Microsoft engineers is contributed accelerated AV1 video encoding on the GPU using a combination of DirectX 12 and the Hardware Media Foundation Transform (HMFT) support that is part of the Windows Media Foundation layer.

6 July 05:04 PM EDT - Intel - Intel Gen12.5 Graphics

Earlier this year Vulkan Video encode was disabled on newer generations of Intel graphics hardware due to insufficient testing with the Intel ANV open-source driver. That impacted Gen12.5 graphics and newer - basically Alchemist and anything newer. Now at least Gen12.5 graphics with the likes of the Arc A-Series is seeing H.264 and H.265 encoding re-enabled.

Longtime AMD Linux graphics driver expert Marek Olšák, who joined Valve earlier this year and now focusing more on RADV rather than the RadeonSI Gallium3D driver, has seen some of his latest work now merged for Mesa 26.2. Marek landed a big overhaul to the variable rate shading (VRS) code that in some cases can double the performance.

Earlier this year AMD announced the Ryzen AI Halo as their in-house mini PC offering built around their leading Ryzen AI Max+ "Strix Halo" platform. After pre-orders began last month, the Ryzen AI Halo is officially beginning to ship this week and over the past few weeks we have been testing it out at Phoronix.

With the AMD Ryzen AI Halo developer platform there is the option of ordering this Ryzen AI Max+ mini PC with either Microsoft Windows 11 or "Linux OS". When receiving a AMD Ryzen AI Halo review sample last month, I fully expected it to just be an Ubuntu LTS install with ROCm preloaded. I was quite surprised when powering it up to find that it's an OS called the AMD Ryzen AI Developer Platform 1 "Rex" and is based on Debian Linux.

Going back to early May there were patches for improving the Linux scheduler to help with gaming performance on old "potato" hardware by providing better cgroup scheduling. Those patches, referred to as the "flatten the pick" patch series, are now slated for introduction in the Linux 7.3 kernel.

6 July 08:29 AM EDT - Intel - Intel i915 + Real-Time

When it comes to the real-time "RT" patches carried outside of the Linux kernel, a number of them pertain to adjustments around the Intel i915 kernel DRM graphics driver. The mainline Linux kernel and its RT support depend upon not building "PREEMPT_RT" for the i915 driver support while patches have been worked on recently for making this Intel kernel graphics driver code play nicely with real-time Linux.

The Ubuntu Foundations Engineering Manager, Ravi Kant Sharma, with Canonical has provided an update regarding the current ARM64 state on Ubuntu Linux.

The Pioneer DJM-S11 is a professional scratch style 2-channel DJ mixer that retails for $2,269 USD. But if currently connecting this expensive piece of kit to Linux, it does nothing and is unusable. With 87 new lines of code, it will begin to work with the Linux 7.3 kernel later this year.

The Unwill laptop driver on Linux for supporting various device-specific features by that major OEM/ODM will be seeing several new features with the Linux 7.3 cycle later this year. One of the most notable users of the Unwill driver is Bavarian Linux PC vendor TUXEDO Computers.

In addition to Sunday's release of DXVK 3.0.1, D7VK 1.12 was separately released as the latest version of this implementation for Direct3D 7 and older atop the Vulkan API.

The FEX Emulator that allows running Linux x86/x86_64 software on ARM64 (AArch64) systems, including the likes of Wine / Valve's Steam Play (Proton) for Windows gaming on ARM, is out with its newest monthly feature release. The Valve-backed project for running x86_64 games and other software on ARM for the upcoming Steam Frame and other more typical ARM Linux systems has been baking more optimizations and improvements.

A set of patches to the Linux kernel's Direct Rendering Manager (DRM) scheduler that is shared among different kernel graphics drivers is showing the potential of delivering much lower job submission latency when the system is loaded with many runnable CPU processes.

One area of Linux hardware testing I haven't explored much in many years has been modern USB video capture for the lack of said hardware. The last time I did much video capturing on Linux was during the Hauppauge PCI card days. It turns out though that USB video capture of 4K 60 FPS content has been a pain point under Linux but is finally smoothing out with newer versions of the Linux kernel.

For those that missed Phoronix turning 22 years old last month when running a special to help support the site, a few readers mentioned recently they missed out on seeing the deal in time. Paired with the US Independence Day holiday and summer sales elsewhere, now through 10 July is a Phoronix Premium summer sale if wishing to view the site ad-free while supporting the daily open-source/Linux news coverage and relentless Linux hardware testing.

Some post-merge-window code changes merged overnight ahead of Linux 7.2-rc2 this weekend is hardening the kernel's BPF code against JIT spraying attacks.

Currently measuring in at 32 patches, SUSE engineer Juergen Gross has been leading the effort to end the Linux kernel's usage of their 32-bit model specific register (MSR) interfaces so the more modern 64-bit interfaces can be exclusively used. This allows for better code unification and cleaning up the MSR code.

The ReactOS project that is striving to be the "open-source Windows" with Windows driver and software binary compatibility hit another milestone today. ReactOS to date has primarily targeted Windows NT 5.2 as the architecture from Windows XP and Windows Server 2003 but with an eye toward Windows NT 6.0 for Windows Vista and later compatibility with software. ReactOS has now landed their first NT6 system call.

A change proposal under consideration for Fedora Linux 45 would enable x86_64 Shadow Stack usage by default in the name of better security on modern Intel and AMD systems.

The EFS file-system was used for non-ISO9660 CD-ROMs and disk partitions on SGI IRIX before IRIX 6.0 switched over to XFS. Inside the Linux kernel has been a read-only EFS file-system driver without a maintainer for 20+ years while for Linux 7.3 it's expected to be removed.

2 July 11:11 AM EDT - AI - AI Agent Attribution On Patches

When AI/LLM agents are used in the creation of Linux kernel patches, the policy for a while now has been that it should be specified using an "Assisted-by" tag as part of the patches/commits. But Linux kernel developers this week have been discussing whether to revise that policy or to potentially eliminate it.

2 July 09:08 AM EDT - Intel - GCC ACE Patches

The x86 Ecosystem Advisory Group led by Intel and AMD recently firmed up the AI Compute Extensions (ACE) specification for optimizing x86 for AI computation tasks around matrix multiplication and the like for machine learning workloads.
