It's looking like IO_uring zero-copy receive support should be ready for the Linux 6.15 kernel cycle this spring...

Last week when RADV lead developer Samuel Pitoiset with Valve was commenting on the AMD RDNA4 state with the Mesa RADV driver it was noted that Vulkan cooperative matrix support, Vulkan Video encode/decode, and DCC support were still missing. But in the past week one of the items is now crossed off the list and another is continuing to see new patch activity...

With the GCC 15 compiler having progressed to its final stage of development prior to the GCC 15.1 stable release in the likely March~April time frame, I've begun testing the updated GNU Compiler Collection on some test systems. Overall GCC 15 is looking nice and on AMD Zen 5 "znver5" in particular seeing some solid gains over GCC 14. Here are some initial performance benchmarks of the GCC 15 compiler.

Following arguments on the Linux kernel mailing list the past few days over some Linux kernel maintainers being against the notion of Rust code in the mainline Linux kernel and trying to avoid it and very passionate views over the Linux kernel development process, Asahi Linux lead developer Hector Martin has removed himself from being an upstream maintainer of the ARM Apple code...

Despite Serpent OS development said to be slowing down to a lack of funding, they are hoping for the best and aiming to push forward with this original, from-scratch Linux distribution...

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...

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...

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...

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.

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...

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...

With Linux 6.14-rc1 released I have begun trying out the new development kernel on a few systems locally. At least for high core count hardware tested thus far, Linux 6.14 at the moment during this early testing phase is sporting some performance regressions within some multi-threaded workloads.

With Firefox 135 released, Firefox 136 is now in beta. Most notable with this next iteration of the Mozilla Firefox web browser is finally enabling hardware video acceleration by default for AMD GPUs on Linux...

Landing this week in the FFmpeg open-source library that is widely-used by multimedia applications was NVIDIA video acceleration improvements for Blackwell GPUs. Over on the AMD side, there are also some interesting changes to have been merged this week into upstream FFmpeg...

While the Linux kernel itself may not be often viewed as a bottleneck to typical high performance computing (HPC) workloads, optimizing the Linux kernel with Profile Guided Optimizations (PGO) can prove worthwhile for those seeking maximum performance potential. A presentation this past weekend at FOSDEM 2025 is highlighting around a 3% performance gain for HPC software compiled with PGO enabled...

The Rust-written Redox OS open-source operating system is out with a new status report to highlight the progress their developers made over the course of January...

The Ubuntu Mainline Kernel PPA for years has been a great feature for Ubuntu users to be able to easily fetch and run the newest upstream kernel whether it's the latest stable kernel version, one of the weekly release candidates, or even the very leading-edge daily Git kernel builds. Sadly for months now this service has been out of order...

Initially merged back for the Linux 6.13 kernel was EXECMEM_ROX support for module text on x86_64 systems. With this caching of large ROX pages it can help with lowering TLB instruction pressure and enhancing performance. But this EXECMEM_ROX support that was contributed by a Microsoft engineer ended up being reverted in the final days of Linux 6.13. The revert came due to bugs and not having any Linux x86 maintainers signing off on the code. This code has been getting into shape for trying again with the mainline kernel...

For those wondering whether Debian 13 would see the upcoming GNOME 48 desktop packages given the upcoming Debian 13 "Trixie" development freezes, it looks like this updated GNOME release will be squeezed in...

Igalia engineers Jose Maria Casanova Crespo and Maira Canal presented at FOSDEM this past weekend in Brussels around the efforts by this open-source consulting firm to further enhance the 3D performance out of the Raspberry Pi single board computers...

Serpent OS is the original Linux distribution started by Ikey Doherty of Solus Linux fame and has been pursuing its own package management system and new innovations in the Linux distribution landscape. While there has been recent success and new development builds coming out, feature development on Serpent OS is expected to slowdown now due to a lack of project funding...

In addition to the FreeBSD Foundation funding work on s0ix sleep state support as part of their initiative to improve FreeBSD's support for modern laptops, they have also been funding work on a number of other objectives, including better WiFi driver coverage. A milestone now being achieved for 2025 is getting a proof-of-concept Intel 802.11 a/b/g WiFi driver support working for this BSD operating system...

Red Hat's Kpatch, Oracle's Ksplice, and SUSE's kGraft are the most well known solutions currently for Linux kernel live-patching primarily for applying security patches to running Linux servers. It wasn't on my bingo card for insurance giant GEICO working baking their own Linux kernel live-patching solution, but they announced it this weekend and it will soon be open-source...

Cloud Hypervisor 44 is now available as the newest version of this security and cloud minded Virtual Machine Monitor (VMM) that operates atop Linux's KVM and the Microsoft MSHV Hypervisor...

Three more PCI device IDs were added today to the Intel open-source Mesa 3D graphics driver code for Battlemage that could be for future higher-end products or along the lines of Data Center GPU Flex Series or other products...

Last week I wrote about the crisis plaguing X.Org / FreeDesktop.org with losing out on their cloud/server infrastructure due to losing out on their free server resources provided by Equinix at the end of April. It's not only FreeDesktop.org and all those hosted projects now rushing to find hosting alternatives and sponsorships to cover new costs, but it turns out the Alpine Linux project is also in a similar position...
