Along with the many x86/x86_64 improvements and some ARM64 architecture improvements (albeit slowed down by the AI/LLM noise affecting the development pace), the RISC-V architecture changes were merged last week for the ongoing Linux 7.2 kernel development.

Following last week's major Plasma 6.7 release, Plasma 6.7.1 is now available today with an initial assortment of bug fixes.

As part of today's USB/Thunderbolt subsystem updates for the ongoing Linux 7.2 kernel merge window, USB4STREAM was merged as a nifty and exciting addition to opening up some interesting USB4 connnectivity use-cases for high speed, low latency data transfers.

Back in March Intel announced the Optimization Zone as a new initiative for helping server administrators and developers better maximize the performance of different workloads running on Intel hardware. Out today is the Intel Optimization Zone 1.1 release with more workloads now covered for squeezing out the most performance on Intel CPUs.

Valve today finally revealed pricing on their SteamOS Linux-powered Steam Machine living room PC. Given the ongoing RAM and storage pricing pressure, the Steam Machine pricing comes in at the high-end.

Released last week was Bcachefs 1.38.6 with a host of performance improvements to this out-of-tree, copy-on-write file-system. Given all the performance improvements and this being the first release since Kent Overstreet dropped the "experimental" flag on the file-system, I decided to fire up some benchmarks looking at how the Bcachefs file-system performance has changed with this new version.

Over the past half-year, Xfwl4 has been developed as a Wayland compositor for the Xfce desktop environment. Released this weekend was the first preview release of Xfwl4 in alpha form.

It's been 14 years already since Microsoft announced the Surface RT hybrid tablet as their first-generation Surface device for going up against the Apple iPad. All these years later, this NVIDIA Tegra 3 powered device is finally seeing a mainline Linux kernel driver for supporting battery and charger status.

Back in March AMD introduced ROCDXG to improve their Windows Subsystem for Linux support. This improved Windows Subsystem for Linux "WSL" support with the ROCm compute stack is a cleaneer architecture, open-source compared to their legacy WSL code having closed bits, and more robust handling. Today they issued a new ROCDXG library release to further enhance their WSL support.

Miracle-WM 0.10 released on Sunday as the newest feature release for this Mir-based Wayland compositor. With this new release is also acknowledgement they are hoping to cross the "1.0" milestone later in the year.

Merged today to Mesa 26.1 is the Ray-Tracing Inspector "RTI" as a new GUI created by developers on Valve's open-source Linux graphics team. The Ray-Tracing Inspector is designed to help in analyzing and optimizing the Vulkan ray-tracing performance as part of their continued work on further bettering the Radeon RADV RT performance for Steam Play / Linux gaming.

The HID subsystem updates have landed in the Linux 7.2 kernel with some treats that will excite Linux gamers and other desktop users.

Merged last week for the Linux 7.2 kernel were all of the sched_ext changes for this extensible scheduler support that allows loading BPF programs from user-space for handling scheduling tasks. Linux 7.2 continues building out sched_ext's sub-scheduler support.

Early AMD Radeon Graphics Core Next "GCN" GPUs are seeing work to improve the GPU recovery process in the event of hangs. This work is yet another improvement for older AMD GPUs being led by Valve's open-source Linux graphics driver team.

As a follow-up to last week's article around Firefox leveraging zlib-rs and some nice upstream improvements to this Rust-based Zlib implementation, the zlib-rs 0.6.4 release is now available to ship all of these latest enhancements.

Last month Qualcomm engineers posted patches bringing up the Lenovo Yoga Slim 7x Gen11 Snapdragon X2 laptop on Linux. Sent out this weekend were a new set of patches from Qualcomm for bringing up the HP EliteBook X G2q laptop model powered by the Snapdragon X2 Elite SoC.

Mesa's Vulkan windowing system integration (WSI) code now has support for present timing support "VK_EXT_present_timing" with X11 and XWayland.

Google Antigravity with the Gemini 3.5 Flash model helped a Linux user sort out a situation where his laptop was taking around 36 seconds to boot the kernel, which shouldn't be the case for the high-end laptop with AMD Ryzen 9 processor and 32GB of RAM. It ended up being yet another case of device firmware issues, but now a Linux kernel patch is pending for working around the issue on the ASUS ROG Strix G16 G614 laptop while discussions are ongoing in getting the vendor to provide a proper firmware fix.

KUnit as the unit testing framework for the Linux kernel and was inspired in part by Java's JUnit when originally conceived, is now finally able to output to the JUnit format for better interoperability with other CI systems and the like that standardize on that common format.

When going through the VFIO subsystem patches for the ongoing Linux 7.2 merge window, there isn't too much to get excited about for end users with these changes. But there is the first time mentioning "Blackwell-Next" enablement by NVIDIA for the Linux kernel.
