An initial set of Linux kernel patches were posted this week for allowing USB Rust kernel drivers to be developed for Linux.

Introduced earlier this month with the Vulkan API 1.4.325 spec update was the introduction of the untyped pointers extension with VK_KHR_shader_untyped_pointers and SPIR-V's underlying SPV_KHR_untyped_pointers for providing an alternative option to strongly-typed pointers. As of yesterday the Mesa Radeon Vulkan driver "RADV" is now supporting this untyped pointers extension.

Generative AI "GenAI" is now being used in part to help determine the Linux kernel patches that should be back-ported to prior current stable Linux kernel releases such as the all-important Linux Long Term Support (LTS) branches.

There's a follow-up to yesterday's surprising story of Alyssa Rosenzweig stepping away from Asahi Linux and that ARM graphics driver work where she led reverse engineering and development of the Asahi Gallium3D and HoneyKrisp Vulkan drivers within Mesa. She's now working at Intel on their Linux graphics drivers.

The NOVA open-source kernel graphics driver continues getting slowly built-up for the NVIDIA RTX 20 "Turing" and newer GPUs that sport the GPU System Processor (GSP) for easing the hardware initialization and management of modern NVIDIA GPUs within the mainline kernel. This Rust-written kernel driver now has patches pending for booting up the NVIDIA GSP to its RISC-V active state.

QEMU 10.1 was released overnight as the latest iteration of this open-source machine emulator that plays an important role in the Linux virtualization stack.

As another very unfortunate setback for the Asahi Linux project moving forward after Hector Martin left the project as did Asahi Lina pausing work on open-source Apple driver development, Alyssa Rosenzweig announced today that she is stepping away from the project following the successes in bringing up Apple M1 and M2 graphics drivers for Linux.

A number of yet-to-be-completed changes/features have been delayed from Fedora 43 to Fedora 44 while permission is granted for a few features to still land late in the Fedora 43 cycle.

Earlier this month I ran some benchmarks of Mesa's Rusticl OpenCL driver against AMD ROCm on Strix Halo. Those benchmarks caught many by surprise with how well that Rust-based open-source OpenCL driver was working on AMD GPUs for being a generic OpenCL implementation built atop Mesa's Gallium3D. For those curious about the potential of Rusticl on the Intel graphics side, here are some Battlemage benchmarks for Rusticl up against Intel's official Compute Runtime driver stack.

While the Framework 13 was upgraded earlier this year with a motherboard upgrade for the AMD Ryzen AI 300 series "Strix Point", the larger Framework 16 has been stuck in the Zen 4 era. But today Framework announced a new upgrade path for this 16-inch modular laptop for the Ryzen AI 300 series as well as NVIDIA GeForce RTX 5070 discrete graphics.

LLVM 21.1 is out today as the first stable version of the LLVM 21 compiler stack. This half-year stable release to the open-source LLVM compiler software brings new hardware support, new language features, and a lot of other enhancements throughout this massive and widely-used codebase.

While the ATI Radeon 9000 / X300 / X500 / X600 series "R300" GPU support has long been unmaintained on the Microsoft Windows driver side, thanks to the open-source community the Linux driver support keeps going for the old ATI R300 GPUs with that driver also supporting the X700 / X800 "R400" and X1000 "R500" series graphics cards too. Two more OpenGL extensions are now wired up for the old R300 Gallium3D driver within Mesa.

Mir 2.22 is out today as the newest version of this Canonical project providing libraries for building Wayland-based shells/compositors. Mir 2.22 brings some notable improvements around NVIDIA GPU/driver support as well as initial preparations for Rust programming language support.

AMD and IBM announced a joint collaboration today around quantum-centric supercomputing. IBM's quantum computing expertise is to be paired with AMD's AI and HPC technology like their Instinct accelerators to help accelerate quantum-centric supercomputing.

Linux's classic initial RAM disk "initrd" support might finally be on its way out of the Linux kernel depending upon feedback from stakeholders. Long live initramfs.

Red Hat engineers have been rewriting Greenboot in the Rust programming language to replace the Bash-written version of this generic health check framework for systemd, bootc, and RPM-OSTree based Linux environments. That Rust rewrite of Greenboot is now cleared for appearing in the Fedora Linux 43 release.

GhostBSD 25.02-R14.3p2 was announced this evening as the newest incremental update to this FreeBSD 14 based operating system focused on providing a nice out-of-the-box desktop experience. Notable with this new GhostBSD release is now shipping a Gershwin community preview for this desktop environment focused on providing a Mac OS X like user experience, complete with GNUstep usage.

OpenZFS 2.4-rc1 was released a few days ago with faster encryption performance using AVX2 and other enhancements. For those just looking for bug fixes and expanded Linux kernel compatibility, OpenZFS 2.3.4 is out today as the newest stable point release.

On this 34th birthday since the Linux kernel was announced, coincidentally there's a new patch series out there for one of the oldest drivers: the floppy disk driver.

Stemming from a request by a Phoronix Premium reader wondering about some fresh historical kernel performance comparison numbers, today's benchmarking is looking at the performance of the LTS and latest stable Linux kernel versions going back to Linux 5.15 LTS in 2021. For testing an AMD EPYC Milan-X server was used for compatibility back through Linux 5.15 LTS with some rather impressive results for testing these major Linux kernel releases of the past four years.
