As a very exciting improvement for the open-source PostgreSQL database server, it has merged initial support for making use of IO_uring on Linux servers for asynchronous I/O and can provide for some nice performance improvements.

Linux sound subsystem maintainer Takashi Iwai of SUSE has submitted all the feature updates slated for Linux 6.15. There is a lot of new audio hardware support and other enhancements that are now merged for this next kernel release.

Earlier this month Mesa deprecated the Clover OpenCL driver in favor of the modern Rust-written Rusticl Gallium3D state tracker. Clover is expected to be removed in Q3's Mesa 25.2 release while today the RadeonSI driver has decided to preemptively remove its Clover support.

NVIDIA has published new Vulkan beta driver builds for Windows and Linux that introduce VK_KHR_shader_bfloat16 for BFloat16 "BF16" support within shaders.

Submitted today for upstreaming into the Linux 6.15 kernel is support for the Versal NET SoC, an addition to the AMD/Xilinx Versal family that doesn't appear to have been talked about much publicly yet but should be an interesting addition to their product line-up.

Microsoft last year announced the open-source Hyperlight project as an embedded VMM for use as a micro-VM manager of sorts that can be run within Windows and Linux applications. This VM-based security for small embedded functions now has its scope expanded with the open-source release today of Hyperlight Wasm for bringing in WebAssembly to the party.

While there is a lot of exciting new x86_64 CPU features coming with Linux 6.15, there is also some of the not so fun changes too: namely the "x86/bugs" pull request to bring the latest CPU security mitigation work to the mainline kernel.

The x86 platform drivers co-maintainer Ilpo Järvinen sent out the pull request today of all the feature additions set for the in-development Linux 6.15 kernel. As usual, most of the platform-drivers-x86 material is around improvements to benefit modern Intel Core and AMD Ryzen laptops.

The Linux Error Detection And Correction (EDAC) subsystem updates have been merged for the ongoing Linux 6.15 kernel.

AerynOS 2025.03 is now available for this Linux distribution that began life as Serpent OS as a new original distribution started by Ikey Doherty of Solus Linux fame.

KDE developer David Edmundson has published a lengthy blog post today outlining the long-standing challenges they have with the SDDM display manager, unimplemented features they want out of a log-in manager, and acknowledging GNOME's GDM as a "gold standard" for display managers. While not yet an official project, they have begun working on a new KDE Login Manager for improving the situation.

The Linux 6.15 kernel is set to remove support for IBM Cell Blade servers for those server platforms from around two decades ago that used the Cell Broadband Engine Architecture processors. IBM Cell Blades at the time powered a few supercomputers but these IBM QS20 / QS21 / QS22 platforms are no longer relevant and the IBM Linux kernel maintainers no longer even have these platforms available/running. With no apparent users remaining, it's time to say goodbye to the IBM Cell Blades from the mainline kernel.

Among other Linux Virtual File-System (VFS) changes submitted and already merged for Linux 6.15 was a set of minor performance optimizations around VFS file operations.

Intel engineers today released LPMD 0.0.9, the newest version of their open-source Low Power Mode Daemon for Linux systems to optimize active idle power consumption on Intel Core processors.

With the Microsoft Hyper-V virtualization updates for the Linux 6.15 kernel there are two new features worth mentioning.

Merged today for the recently-opened Linux 6.15 merge window were all of the "x86/core" changes that are particularly heavy on new feature work for both Intel and AMD x86/x86_64 processors. This is easily quite one of the most significant Intel/AMD CPU set of updates in a given kernel cycle in quite some time.

XZ 5.8 is out today as the first notable feature release since last year's malicious backdoor in XZ 5.6 inserted by a then-co-maintainer of the project. XZ 5.6.2 was out last May while XZ 5.8.0 is now stable today for bringing new features to this lossless data compressor project.

MPV 0.40 was just released as the newest version of this open-source media player derived from MPlayer/MPlayer2. With the MPV 0.40 release there is support for HDR videos on Wayland using the new color management protocol along with a variety of other new features.

Fwupd 2.0.7 brings the newest plug-ins and expanded hardware support for being able to update a variety of system and device/peripheral firmware under Linux.

Earlier this month for launch-day there were NVIDIA GeForce RTX 5070 Linux GPU compute benchmarks. The graphics/gaming benchmarks of the GeForce RTX 5070 on Linux were held up by waiting for a new R570 Linux driver release with proper support for this new Blackwell graphics card. Last week that new Linux driver arrived in the form of the NVIDIA 570.133.07 Linux build. That new NVIDIA Linux driver is working out great with the GeForce RTX 5070 Founder's Edition and in this article are some initial Linux gaming/graphics performance benchmarks for that new graphics card competing with the AMD Radeon RX 9070 series.
