With the Linux 6.14 kernel Bcachefs has its last big planned on-disk format upgrade before removing the "experimental" tag on this copy-on-write file-system. Well, that's the hope at least. In addition to some early fixes last week, some additional Bcachefs fixes are now pending for merging to the mainline kernel while continuing to track down some other bugs...

NVIDIA on Thursday published their first public beta of their RTX Neural Texture Compression "RTX NTC" software development kit...

AMDVLK 2025.Q1.1 is out this morning as the first update of the year to this official AMD open-source Vulkan driver for Linux systems...

A year ago I raised attention about crypto-config as a new Ubuntu project for system-wide cryptography configuration. That crypto config tool continues being developed by Canonical engineers for a gradual roll-out into the Ubuntu Linux landscape...

Android and Chrome OS already are carrying the VirtIO Media driver as a means of enabling virtualization of host media devices into a guest while now patch review is underway in trying to get VirtIO Media upstreamed in the mainline Linux kernel...

After recently re-visiting the AMD EPYC 9005 series AVX-512 performance, I followed up with some fresh SMT benchmarks looking at the performance benefits and power of toggling Simultaneous Multi-Threading on the 5th Gen AMD EPYC "Turin" hardware. Here are some fresh numbers looking at the SMT performance with AMD Zen 5 server processors.

While the AMDXDNA driver was merged for the Linux 6.14 kernel for enabling the Ryzen AI NPUs atop a mainline kernel build, there's still the user-space software needed for making use of the neural processing units found in Ryzen AI SoCs. AMD talked more about programming Ryzen AI NPUs last weekend in Belgium at the FOSDEM 2025 developer conference...

Intel's software engineers working on the OpenVINO AI toolkit today released OpenVINO 2025.0 that brings support for the much talked about Deepseek models along with other large language models (LLMs), performance improvements to some of the existing model support, and other changes...

LibreOffice 25.2 is out this morning as the newest half-year update to this leading cross-platform, free software office suite...

Mesa 25.0-rc2 was released yesterday and it's rather boring on the changes, but that's a good thing during this bug fixing phase...

With the recent GNU Binutils 2.44 release, one of the changes is worth calling out in its own article: the GNU Gold linker is now officially deprecated and is now being segregated to its own extra Binutils package but risks being removed all together without new developer volunteers stepping up to maintain this linker...

Red Hat engineer and PipeWire lead developer Wim Taymans presented at FOSDEM 2025 last weekend around the state of the PipeWire project for this integral component to the modern Linux desktop...

The modern Intel "Xe" Linux kernel Direct Rendering Manager (DRM) driver as the clean successor to the i915 driver has been an experimental option for Tigerlake and newer but only for Xe2 graphics (Lunar Lake / Battlemage) and newer is it used by default. But Google at least for their Chromebook use-cases is entertaining the idea of switching over to the Xe driver rather than the long-used i915 kernel driver for Alder Lake era hardware...

Yesterday I showcased Linux 6.14 Git performance worse than Linux 6.13 and 6.12 in a number of multi-threaded workloads. Due to that initial discover being on the lone AMD EPYC Turin 2P server that is always busy running through new benchmarks for future content as well as I am being persistently short on time and constantly under pressure due to the state of the web/ad industry, I didn't expect to get around to digging deeper into the problem in the near-term. But as I ended up being able to reproduce some of the regressions on a System76 Thelio Major workstation at my desk with the still mighty powerful Ryzen Threadripper 7980X, I was able to turn around a quick bisect...

Merged last year for the Linux 6.12 kernel was sched_ext for allowing extensible scheduler possibilities by allowing schedulers to be implemented as eBPF code and dynamically loaded into the kernel. This allows for rapidly developing new schedulers as well as exploring other new possibilities around more intelligent kernel scheduling decisions. Meta, Google, Canonical (Ubuntu), and others have been big proponents of sched_ext and NVIDIA is also increasingly vocalizing their support for these extensible scheduler opportunities...

AMD announced today the release of Schola 1.0 as an open-source reinforcement learning library that is being made available under an MIT license and as part of their GPUOpen software collection for helping game developers...

Now that the Linux 6.14 merge window wrapped up this past weekend with the release of Linux 6.14-rc1, here is a recap of all the great new features, hardware enablement, and other improvements to find with this kernel.

One of the set of patches for the Linux kernel that we have been looking forward to but that wasn't wrapped up in time for the recent Linux v6.14 merge window was the work enabling use of the AMD INVLPGB instruction on Zen 3 CPUs and newer for broadcast TLB invalidation. This can lead to a nice performance bump in some workloads while the eighth iteration of those patches were posted overnight...

The Linux Foundation by way of their LF Energy initiative announced today the release of SEAPATH 1.0, a security-hardened real-time hypervisor...

Red Hat engineer Anirban Sinha presented at FOSDEM 2025 last weekend in Brussels on F-UKI, a new project being worked on at Red Hat as part of the confidential computing push for loading guest firmware within a Unified Kernel Image (UKI) for confidential VMs...
