Following a presentation at last week's Linux storage, file-system, memory management and BPF summit (LSFMM) in Croatia where Linux I/O overhead compared to the Storage Performance Development Kit (SPDK) was presented, Jens Axboe was motivated to pursue some new Linux kernel optimizations for greater per-core I/O performance. This lead IO_uring developer and Linux block maintainer has managed to achieve around a 60% increase to the per-core I/O performance with his latest patches.

With half-way through the Debian 14 "Forky" development cycle, the Debian release team is out with an update this weekend and some big news.

The newest open-source AMD Linux driver on the Linux kernel mailing list that has recently been undergoing review is prom21-xhci that exposes the temperature sensors found on the AMD Promontory 21 chipsets' xHCI controllers.

New tooling being worked on for possible mainline Linux kernel inclusion is Kconfirm as a new tool for detecting misusage and efforts stemming from Kconfig, the configuration system for kernel builds.

While since GNOME 48 Decibels is the new audio player of the GNOME desktop, there is no shortage of other GNOME/GTK-aligned music players. Last month was the big Amerbol music player update and there are Lollypop and others. The latest GNOME-aligned music player now hitting the 1.0 milestone is Nocturne.

Hyprland 0.55 is out today as a big feature update for this Wayland-based compositor.

FEX 2605 is out this weekend as the newest monthly feature release to this emulator for running Linux x86_64 binaries on ARM64 (AArch64) devices. This is the open-source project sponsored by Valve and planned for use with the upcoming Steam Frame as well as being relevant to Linux gaming on other 64-bit ARM laptops and other devices.

Ubuntu Touch 24.04-1.3 is out this week as the latest maintenance release for this tablet/smartphone-focused Ubuntu distribution.

The open-source, community-developed NVIDIA-VAAPI-Driver that provides a Video Acceleration API (VA-API) implementation built atop NVIDIA's NVDEC video decode interface is out with a new release. This is the open-source project that's motivated by getting accelerated video decoding to work within Mozilla Firefox and other apps when running with NVIDIA's packaged Linux driver.

Merged as part of the perf subsystem fixes overnight is enabling Auto Counter Reload (ACR) functionality for upcoming Intel Xeon Diamond Rapids processors. This ACR enabling for Diamond Rapids "DMR" is happening in time for Linux 7.1-rc3 on Sunday while the work is also marked for back-porting to existing stable kernels.

KDE developers continue to be quite busy in preparing additional Plasma 6.7 desktop features ahead of the stable release due out in mid-June.

FreeBSD 15.1 continues working its way toward a stable release in June. Out today is FreeBSD 15.1 Beta 2.

In late 2023 I reviewed the HP Z6 G5 A workstation that at the time was built around the AMD Ryzen Threadripper PRO 7000 series and NVIDIA RTX Ada Generation graphics. More recently, HP has revised the Z6 G5 A workstation for the latest Threadripper PRO 9000 series and NVIDIA RTX PRO Blackwell graphics. HP sent over the upgraded Z6 G5 A workstation that I've been benchmarking the past few weeks. This workstation remains Linux-friendly down to convenient LVFS/Fwupd support and delivers stellar performance with the Zen 5 Threadripper and NVIDIA Blackwell combination.

A new NVIDIA Labs project is greatly improving the capabilities of using the Rust programming language for developing CUDA kernels for NVIDIA GPUs.

Queued for merging as part of the DeviceMapper changes for the upcoming Linux 7.2 kernel cycle is the new dm-inlinecrypt target for leveraging inline block device encryption.

The Qt Group released the Qt Creator 20 Beta today for this Qt/C++ focused integrated development environment (IDE). In building off the trends of recent releases of Qt Creator and development tools at large, AI integration continues to be a big area of focus.

Last October engineers at Meta announced OpenZL as a format-aware compression framework. OpenZL aims to be speedy yet capable of delivering high compression ratios depending upon what is being compressed. OpenZL is viewed as their next leap in data compression beyond their wonderful work on Zstandard (Zstd). This week there's finally a new OpenZL software release available.

AMD software engineers continue rapidly advancing their open-source software efforts around local AI/LLM use on consumer-class Radeon and Ryzen hardware. AMD GAIA 0.17.6 was released on Thursday with more improvements for local AI processing on Windows, Linux, and even macOS. For those trusting enough in local LLM pipelines to do the right thing, there is even integration now for AMD GAIA to interface with your Gmail account.

With Intel's recently-launched Bartlett Lake P-core-only processors intended for the embedded market, there is a rather surprising oversight under Linux: the Intel P-State driver reporting a 7.0+ GHz clock speed. While many would yearn for a 7GHz CPU, the Core 9 273PE where this issue was discovered in reality can only boost up to 5.7GHz for its maximum turbo frequency.
