A post merge-window change that landed in Linux Git overnight ahead of tomorrow's Linux 7.2-rc2 release is bumping the default limit on the number of supported CPU cores for RISC-V 64-bit. Now by default Linux will support up to 256 cores with RISC-V 64-bit kernel builds.

Along with releasing Plasma 6.7.2 this week, KDE developers continue to be quite busy working on new features and improvements for the Plasma 6.8 release while also furthering along fixes for future Plasma 6.7 point releases.

While typically quite rare encountering a GPU reset under Linux in most conditions, currently if encountering one under GNOME your session gets wiped out. But thanks to a Google Summer of Code "GSoC" project this year, GNOME's Mutter compositor is finally seeing real GPU reset recovery handling.

In working toward the stable GNOME 51 desktop release due out in September, today marks the alpha release of GNOME 51.

The UPower abstraction layer used for power management on Linux systems, especially laptops and desktops, is out with an important fix today to avoid inadvertently falling back to the laptop battery "fast" charging mode on some laptops that in turn could degrade your laptop battery faster.

Vulkan 1.4.356 is out today and it's interesting for the lone new extension debuting: VK_EXT_shader_ocp_microscaling_types. The VK_EXT_shader_ocp_microscaling_types is for enabling the Open Compute Project's Microscaling MX data types to help with machine learning workloads with Vulkan.

With 3mdeb's Dasharo port of AMD openSIL and Coreboot running on the Gigabyte EPYC motherboard, 3mdeb engineers have been devoting more time to their bring-up of Coreboot+openSIL on the MSI PRO B850-P consumer motherboard for desktop AMD Ryzen. They now even have Microsoft Windows 11 working atop this open-source firmware alternative along with other features implemented.

While the Rust Coreutils offers better memory safety than GNU Coreutils due to being written in the Rust programming language, subtle incompatibilities continue to be spotted in the Rust Coreutils implementations of the different commands. The latest coming to light this week was the Rust Coreutils cp command breaking Ubuntu image builds due to differences in argument handling.

On Thursday Intel sent out their first batch of Intel kernel graphics driver changes of new feature material targeting the Linux 7.3 kernel. This first batch of drm-intel-next for v7.3 continues to focus heavily on lining up Nova Lake's Xe3P integrated graphics/display support.

NVIDIA's latest Linux kernel mailing list patches are for providing the Device Tree for the baseboard management controller (BMC) of their Vera Rubin VR-NVL server platform. With the Linux kernel patches and also for U-Boot, it's part of the upstreaming effort for supporting the open-source OpenBMC software on their latest hardware.

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.

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.

Since May we have been benchmarking the SpacemiT K3 RISC-V SoC as one of the first to market RISC-V chips supporting the RVA23 profile. The SpacemiT K3 has shown how far RISC-V performance has come in the past half decade and one of the promising elements of this modern RISC-V SoC with its X100/A100 cores is supporting the RISC-V Vector Extension "RVV" 1.0. In this article are some initial benchmarks looking specifically at the RISC-V RVV 1.0 performance impact in different supported software.

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. The cross-vendor ACE extension is ultimately a successor to Intel's Advanced Matrix Extensions (AMX). Posted to the GCC mailing list today by Intel engineers are the initial patches in preparing the compiler support for ACE.

One month ago we reported on YSERVER as a modern X11 server written in Rust with the help of Claude Code. Since then YSERVER has continued to advance in supporting more X11 functionality thanks to the help of Claude Code (AI) and out today is version 1.3 o this display server.

A security disclosure has been made public today for a yet-to-be-patched arbitrary code execution vulnerability with the KDE Plasma desktop.
