Microsoft's Hyper-V virtualization support within the Linux kernel continues to be steadily enhanced and it's inched along further for Linux 6.18.

One of the exciting additions on the way for the C++26 programming language is a standardized library around Single Instruction Multiple Data (SIMD) operations. This portable SIMD implementation makes it easier to leverage SIMD and data parallelism in C++ for better performance and to work across SIMD architectures like AVX-512.

In addition to last week's HID subsystem pull that brought haptic touchpad support and other exciting additions for Linux 6.18, the input subsystem pull was merged this week to introduce a few new input drivers.

Released this evening is the first beta of the Shotcut 25.10 open-source video editor. This prominent video editing application for Linux systems is introducing yet more AI-powered functionality.

This morning while finishing up work on the concerning Intel open-source comments from Intel Tech Tour in Arizona and summing up the declining open-source contributions and departures of numerous Intel open-source/Linux developers from the company, yet another Linux engineering departure crossed my wire.

In addition to Intel talking up their Panther Lake SoC and its Xe3 integrated graphics at their Tech Tour in Arizona last week, they also hosted sessions on additional aspects of Panther Lake like the IPU 7.5 for web cams and the new NPU 5 IP for AI acceleration. For those wondering, the Intel NPU 5 support under Linux is already largely squared away.

The expanse of Rust-written kernel drivers for Linux continues. Posted to the Linux kernel mailing list is the first LED kernel driver written in the Rust programming language.

Intel Tech Tour 2025 in Arizona was primarily focused on disclosures around Xeon 6+ Clearwater Forest and Panther Lake / Xe3 but during the opening keynote was also teasing a yet-to-be-announced inference-optimized GPU.

At the Intel Tech Tour in Arizona, an entire slot was devoted to talking up their next-gen IPU to be found with upcoming high-end Panther Lake laptops. This was in addition to the main Intel Panther Lake / Xe3 presentation. IPU product marketing manager Tomer Rider presented on their IPU7.5 tech, but unfortunately like we have seen with Intel's IPU tech since Alder Lake, there are user-space binary blobs involved.

A few months back it was brought up on the Intel driver mailing list around SR-IOV support for Panther Lake's Xe3 graphics. This goes along with Intel open-source Linux driver developers being quite busy on SR-IOV support for Battlemage dGPUs as part of their Project Battlematrix. Unfortunately, I wasn't provided any answer at Intel Tech Tour in Arizona whether SR-IOV support will be found with all Panther Lake SKUs or reserved for select offerings.

In addition to announcing Clearwater Forest as Xeon 6+, Intel also used their Tech Tour 2025 Arizona event for predominantly focusing on upcoming Panther Lake SoCs for laptops shipping in 2026.

Details during the Clearwater Forest briefing at Intel Tech Tour Arizona were rather light... Especially as for what's known about the cores already from prior events like Hot Chips and other Intel disclosures around the Darkmont E-core. But we do now know the branding: Xeon 6+ for Clearwater Forest.

For the past 21+ years of running Phoronix and even longer than that being a Linux user, I have loved and consistently promoted Intel's open-source efforts and leading Linux support. Even through Intel's difficult periods of delayed and stagnate hardware launches, what had remained consistent at the company and rather legendary had been their open-source contributions. From the Linux kernel to compiler toolchains and hundreds -- if not thousands -- of different open-source projects over the past two decades have been advanced thanks to Intel's open-source leadership. It is with much sadness that my faith and confidence in Intel's open-source leadership position is being questioned and questioning the direction they are now apparently steering their open-source focus/philosophy moving forward.

Proposed last year was GL_EXT_mesh_shader as a cross-vendor mesh shading extension. That OpenGL mesh shader work led by an AMD engineer was merged today into the OpenGL Registry.

Merged overnight to the Linux 6.18 kernel were all of the perf subsystem tool updates. Notable with the perf tooling updates is a new Python application living within the kernel source tree.

PoCL 7.1 is now available for this "Portable Computing Language" implementation that brings OpenCL to CPUs and other devices/accelerators via support for the various LLVM back-ends such as NVIDIA PTX, Intel GPUs via Level Zero, etc.

FEX 2510 is out as the newest release of this open-source emulator for running x86/x86_64 applications on ARM64 (AArch64) Linux devices. Making FEX all the more popular is its continued ability for running Wine/Proton for handling Windows games on ARM64 Linux.

Canonical just officially announced the release of Ubuntu 25.10 as the newest non-LTS release of Ubuntu Linux.

So far the upstream GCC compiler hasn't seen any target enablement for Intel's future Nova Lake processors (a.k.a. -march=novalake support) but merged yesterday for the GNU C Library was initial targeting for Nova Lake as well as Wildcat Lake.

Last month the Alliance for Open Media "AOMedia" began teasing that the AV2 video codec will release later this year. They have now sent us word that later this month will be a virtual event talking more about this successor to AV1.
