Ubuntu/Canonical has for a while now promoted the prospects of Rust programming within the Linux kernel and one of their kernel engineers, Andrea Righi, wrote a Rust-written Linux scheduler with promising results that leverages eBPF for dynamically loading it at run-time. While Ubuntu isn't yet committing to using it as part of their distribution, appearing on the Ubuntu blog today was more praise for the work and even talking about the potential for a "micro-kernel design" in the future via leveraging Rust and eBPF.
KiCad 8.0 has been released as the latest major feature release for this open-source Electronics Design Automation (EDA) software suite. KiCad supports designing PCB layouts, provides a 3D viewer for inspecting PCBs, and other functionality.
Ant Group and Alibaba have proposed PVM, the Pagetable Virtual Machine, as a new virtualization framework built upon the Kernel-based Virtual Machine (KVM) hypervisor. PVM does not require hardware-assisted virtualization while working with KVM-enabled software like Kata Containers.
Last July AMD launched the Radeon RX 7900 GRE graphics card in China with a reduced Navi 31 GPU. Beginning tomorrow, 27 February, the Radeon RX 7900 GRE is being made available worldwide. Today the review embargo expires on the Radeon RX 7900 GRE for the worldwide scope and within the US will be priced around $549 USD.
Released last June was the SDDM 0.20 display manager with experimental Wayland support and other enhancements after being in development for three years. Out this morning is SDDM 0.21 as another step toward SDDM 1.0 with improved Wayland support and other enhancements to this Qt-tooled display manager.
Longtime AMD open-source Mesa developer Marek Olšák after more than one decade working officially for AMD and years before that as an independent open-source contributor going back to the R300g days still has not run out of new performance optimizations to pursue. The most recent accomplishment for this leading Mesa contributor are some refinements to the OpenGL threading "glthread" code for lowering the memory footprint.
Intel confirmed at their MWC 2024 briefings that Granite Rapids D will debut in 2025 as the successor to Ice Lake D for Xeon D edge processors.
When it comes to neural processing unit NPU/AI accelerators for Linux there is open-source options with the likes most notably of Intel-owned Habana Labs leading the way, Intel's iVPU driver for the NPU found within Meteor Lake SoCs, AMD recently posting a Ryzen AI Linux driver, etc. When it comes to reverse-engineered efforts, the Etnaviv project has expanded its scopes from just Vivante graphics IP to also embracing the Vivante NPU IP for running workloads like TensorFlow Lite. With the latest open-source achievements, the Etnaviv NPU performance is coming incredibly close to the proprietary and official driver.
WayVNC 0.8 was released this weekend as the VNC server for wlroots-based Wayland compositors like Sway. WayVNC attaches to wlroots-using compositors and creators virtual input devices and exposes the display via the RFB protocol for the lack of Wayland having any standardized VNC-type support for remote/network computing.

Sent in this morning via the "x86/urgent" pull request ahead of the Linux 6.8-rc6 kernel later today is a set of patches from Intel to ensure clearing of CPU buffers using the VERW instruction happens at the latest possible point in the return-to-userspace code path. This is being done to better protect against CPU bugs like Microarchitectural Data Sampling (MDS).
Kent Overstreet on Saturday evening posted a set of 21 patches to overhaul the disk accounting code for the Bcachefs file-system. This change does break compatibility with the existing disk accounting on-disk format and thus will require an upgrade when moving to the new version, which may land for Linux v6.9.
Microsoft's in-house CBL-Mariner Linux distribution has routinely seen weekly-ish updates to this open-source code used within Azure, WSL, and other areas of the Redmond company. But it's been one month since the prior CBL-Mariner 2.0 release... That changed Saturday night with a shiny new release.

While the Linux 6.8 kernel merge window has been over for several weeks now, due to a busy February of new hardware releases and lots of Linux hardware reviews/benchmarking, I've been behind in writing up my Linux 6.8 feature recap. For those wanting a concise look at the many great changes coming with Linux 6.8 that will debut as stable in March, here's an overview of the interesting Linux 6.8 changes.

The Simple DirectMedia Library that is commonly used as an abstraction layer by cross-platform games and other software is now introducing a Vulkan renderer with SDL3.
As a follow-up to the news of Mesa looking at enabling Zink by default as part of the drivers to build out-of-the-box, that change has now been merged. Additionally, the D3D12 Mesa driver that sees regular contributions by Microsoft engineers is also now being compiled by default when running on Windows.

As part of the recent AMD Ryzen 5 8500G and 8600G Linux reviews I ended up picking up the Core i3 14100 and Core i5 14500 Raptor Lake Refresh processors for the similarly-priced Intel competition. It's not too often receiving review samples from Intel of the lower-end processor SKUs, so I'm back around today with even more benchmarks of these lower-tier AMD and Intel processors. In this article are 500+ benchmarks looking at the CPU and iGPU performance of the Intel Core i3 14100 and Core i5 14500 processors up against the AMD Ryzen 5 8500G and Ryzen 5 8600G processors under Ubuntu Linux.
Canonical has released the Ubuntu 22.04.4 LTS images today as the latest point release for this ongoing Long-Term Support series ahead of the Ubuntu 24.04 LTS debut in April.

With the Zink OpenGL-on-Vulkan driver implementation continuing to prove itself robust and as performant as native hardware OpenGL drivers, the Mesa developers continue exploring new opportunities for it. Given its successes, a merge request has been opened so Zink would become part of the default drivers built by Mesa out-of-the-box without needing to manually enable it for compilation.
Ardour 8.4 was released this week as the newest update to this open-source digital audio workstation (DAW) for Linux / macOS / Windows platforms.
Back in August 2022 DreamWorks Animation announced plans to open-source MoonRay as their production-grade renderer used on films like Puss In Boots: The Last Wish, How To Train Your Dragon: The Hidden World, and other animated films. Nearly one year ago in March 2023 MoonRay was open-sourced as OpenMoonRay while this week brings the latest iteration of it: OpenMoonRay 1.5.
The KDE Plasma 6 open-source desktop environment is launching next week and ahead of that the Slimbook V has been announced, the latest laptop crafted in partnership between the KDE project and Slimbook.

The first "Power11" patches were queued today into the PowerPC's "next" Git branch ahead of the upcoming Linux 6.9 kernel cycle.
Intel has released a new version of QATlib, their user-space support library for the QuickAssist Technology (QAT) via add-in hardware and recent Xeon Scalable processors.
Intel's Iris Gallium3D driver for modern OpenGL support works on hardware going back to old Broadwell processors with "Gen8" integrated graphics as does the HasVK Vulkan driver for Haswell/Broadwell. But in allowing to focus on the common Skylake "Gen9" graphics and newer/future Intel graphics architectures, pending Mesa code is working to split-off that old Broadwell/Gen8 code. The Gen8 support will continue to be in-tree but separated from the rest of the compiler code so that the code can continue to be improved for newer Intel hardware without risking regressions/breaking those still on Broadwell era processors.
WebKitGTK as the port of the WebKit rendering engine used by GNOME Web (Epipahny) and other software for displaying web content is transitioning to using Skia for its 2D rendering.
Fraunhofer on Tuesday released their latest feature update to the Versatile Video Encoder for open-source H.266/VVC encoding.
Mesa 24.1 Git has landed the initial infrastructure for allowing drivers to choose to using Zink instead for OpenGL via this OpenGL-on-Vulkan implementation. The motivating factor for this latest Mesa work is for using Zink atop the NVK Vulkan driver for newer NVIDIA GPUs.
When it comes to today's complex RGB lighting for PC peripherals and the like it's mostly been left up to user-space. With most RGB devices interfacing via USB, it's been up to Linux user-space projects like OpenRGB, OpenRazer, etc, to implement their RGB lighting controls as needed. But as RGB lighting use continues to grow in the PC space for better or worse, there's an increasing need for a kernel API to handle complex RGB devices. Such an API is currently being devised.
