Intel's upcoming Crescent Island product as a reminder is a new inference-optimized Xe3P graphics card with 160GB of vRAM and targeting enterprise AI workloads. Intel's open-source Linux graphics driver engineers continue to be very busy enabling the driver support for Crescent Island as well as making broader Xe3P improvements...

Mike Blumenkrantz of Valve's Linux graphics team has ignited a discussion over potentially shifting some of Mesa's older GPU drivers into a new legacy Git branch in order to better support the more modern OpenGL and Vulkan drivers without having to worry about breaking the legacy drivers and to allow for better cleaning of the Mesa codebase. Among the drivers that could be impacted are the ATI/AMD R300 and R600 drivers and many smaller drivers...

A lot happened in the Linux and open-source world during the month of April. Ubuntu 26.04 LTS and Fedora 44 shipped, a lot of news around age attestation/verification laws, the Linux 7.0 kernel was released, Linux 7.1 is bringing many exciting changes as well as removing of old hardware drivers, the Ryzen 9 9950X3D2 Dual Edition CPU was released, we began testing the Intel Arc Pro B70 "BMG-G31", and much more software and hardware content that made the month interesting. Last month on Phoronix were 303 original news articles and 16 Linux hardware reviews / multi-page featured benchmark articles...

It's not too entirely surprising given the aggressive stance that the CachyOS Linux distribution has taken on out-of-the-box performance, but for those curious, it continues largely leading over the newly-released Ubuntu 26.04 LTS and Fedora Workstation 44 distributions for the leading performance on modern hardware.

AerynOS, the Linux distribution formerly known as Serpent OS, is out with a new monthly ISO refresh and details on other recent improvements to this original, from-scratch Linux distribution...

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...

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...

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...

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.

It's crazy to realize it has been ten years already since Red Hat abandoned their Btrfs plans for Red Hat Enterprise Linux and dropped it, which was a technology preview feature since RHEL6. In its place Red Hat engineers began developing Stratis for next-gen Linux storage with ZFS/Btrfs-like features but instead building atop XFS, LUKS, Device Mapper, and Clevis. After a while since the last major release, Stratis Storage 3.9 released today...

Ahead of the Linux 7.1-rc1 kernel release due out later today for closing the Linux 7.1 merge window, I was curious if all the code removals would lead to a negative change in line count over Linux 7.0. The removals were not enough and Linux 7.1 Git is fast approaching 40 million lines...

Earlier this month on Phoronix we were the first to draw attention to a new fuzzing tool / AI bot uncovering kernel bugs by Greg Kroah-Hartman, the "second in command" for Linux kernel development and stable maintainer. Greg has now shared more light on the "gregkh_clanker_t1000" for this tool that has been uncovering more Linux kernel bugs the past few weeks...
