My initial testing of the Linux 7.1 development kernel on various systems in the lab continues going well. Aside from one main regression in a synthetic micro-benchmark appearing on multiple systems, not seeing much in the way of Linux 7.1 performance concerns thus far and seeing some nice performance gains in select workloads.

GCC 16.1 is now available as the first stable release of GCC 16 as this year's major open-source GNU compiler feature release.

There are two exciting initiatives taking place simultaneously by the 3mdeb consulting firm: the open-source developers are working on an open-source firmware stack for a Gigabyte EPYC server motherboard and they are also working on a similar Coreboot + AMD openSIL port to a Ryzen AM5 consumer motherboard, the MSI PRO B850-P WiFi. While not yet ready for end-users, 3mdeb published their latest blog post to highlight their latest milestone achieved with the openSIL + Coreboot bring-up on the MSI PRO B850-P motherboard.

Posted to the Linux kernel mailing list this week was the newest revision of a patch series originally started in early 2025 by a NVIDIA engineer for accelerating page migration. Now being worked on by AMD engineers, this accelerated page migration via batch copies and hardware offloading continues to show promising results.

Last year with the ACPI 6.6 specification release came revised Collaborative Processor Performance Control (CPPC) support for enhancing the capabilities around this standard for OS management of the performance of CPU cores using an abstract performance scale. That CPPC v4 support is now being worked on for the acpi_cppc Linux driver by NVIDIA engineers.

Following the recent Servo 0.1 release, the Servo project has published their latest monthly status report to highlight recent development efforts around this modern open-source browser engine.

Recently I ran benchmarks looking at the Xe2 graphics performance gains on Intel Lunar Lake over the past year with what's shipped by Ubuntu and comparing against our original tests of the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition. With those Lunar Lake iGPU benchmarks out of the way, here is a look at how the Lunar Lake CPU performance has evolved on Linux since April 2025.

Just days after the Linux 7.1-rc1 kernel release, the Linux kernel's extensible scheduler class "sched_ext" is seeing a lot of bug fixes. Many of these bug fixes aren't just from the Linux 7.1 merge window but a number date back many kernel cycles. This uptick in bug fixes for sched_ext is coming due to increased AI code review.

Back in 2023 the Vulkan API introduced its initial Cooperative Matrix extension and necessary SPIR-V integration for helping with machine learning / AI inferencing use. Since then the cooperative matrix support has continued to be built upon for helping Vulkan in AI/ML areas. Now the OpenCL API is also introducing similar cooperative matrix extensions.

Zed, the cross platform, open-source text/code editor written by the developers behind the Atom editor, has finally reached version 1.0.

Merged today to the GCC Git compiler codebase, which will be for GCC 17 rather than the imminent GCC 16.1 stable release, is adding support for the Chinese-manufactured Hygon C86-4G-M4 / C86-4G-M6 / C86-4G-M7 series x86_64 processors.

Libcamera 0.7.1 released on Tuesday as the newest feature release for this open-source library for camera image signal processors (ISPs) that has grown of importance for the likes of Raspberry Pi and Chrome OS and modern desktop Linux distributions with modern laptop hardware like recent Intel Core (Ultra) laptops.

Weston 16.0 could ship by the end of June with good color management and HDR support along with other new features for this reference Wayland compositor.

A Devuan developer, the Linux distribution that provides a Debian-based operating system without dependence on systemd, is working on "gtk2-ng" for providing modern fixes and improvements to the old GTK2 toolkit.

AMD CEO Lisa Su back at CES 2026 showed off the Ryzen AI Halo box as a mini PC built around their excellent Strix Halo SoC. The Ryzen AI halo box is to serve as an AI development platform to compete with the likes of NVIDIA's DGX Spark and Dell GB10. This week is the first time I am seeing new Linux driver activity specifically referencing this exciting AMD "Halo Box" system.

Back in 2018, Valve open-sourced their Steam networking sockets library as a basic network transport layer for games. This library is used by games from Counter-Strike to Dota 2 and since its public open-source drop has been picked up elsewhere. Finally after going nearly four years without a new version, GameNetworkingSockets v1.5 dropped today.

At the start of April was the peculiar announcement of IBM collaborating with Arm on "dual architecture" hardware. The initial fruits of that collaboration at least are Linux kernel patches for enabling ARM64 virtualization acceleration on IBM Z servers. As we approach the end of the month, IBM has now posted a second iteration of those patches for enabling AArch64 software to run on IBM s390 via the Kernel-based Virtual Machine (KVM).

The past few weeks I have been testing out the new HP Z6 G5 A workstation desktop PC. It's a beast in being powered by the AMD Ryzen Threadripper PRO 9975WX, eight channels of DDR5-5600 memory, and paired with a NVIDIA RTX PRO 6000 Max-Q workstation graphics card. The full review on the HP Z6 G5 A workstation will be published on Phoronix in the next week or so but given the timing and that it shipped with WIndows 11 Pro, here is a look at how Windows 11 Pro is competing against the newly-released Ubuntu 26.04 LTS in creator/workstation workloads.

Lemonade as the open-source local AI server backed by AMD and supported across AMD CPUs / GPUs / NPUs on Windows and Linux is out with a big update.

Germany's Sovereign Tech Agency (Sovereign Tech Fund) has provided critical financial resources to open-source software projects and maintainers the past several years. This has proven to be an incredible effort and today they announced their newest initiative as the Sovereign Tech Standards.
