After various commits to Mesa 25.1 in recent days in preparing for a new paired context registers feature of AMD RDNA4 (GFX12 graphics), the feature today is wired up for the Radeon Vulkan driver "RADV" with the upcoming Mesa 25.1 release. This feature has the possibility of helping performance for new AMD RDNA4 hardware but the performance benefits at this time aren't clear...

Sent out as a request for comments today is a patch series implementing PCACHE, a persistent memory cache for block devices. PCACHE was born out of code originally designed for the CXL block device driver but ultimately is useful outside the context of Compute Express Link as well...

While LLVM LLD and Mold are two popular linkers on Linux systems with the latter being known for its impressive speed and much faster than GNU LD and Gold, this past week Qualcomm open-sourced a new linker: ELD...

Last year work on KDE's Amarok music player was resurrected after a six year development hiatus. With the return to Amarok development it was ported to Qt6 and KDE Frameworks 5. At the end of last year Amarok 3.2 released with initial Qt6 and KDE Frameworks 6 support while retaining Qt5/KF5 support. Now out today is the Amarok 3.3 beta to drop that prior-generation support...

While the Linux 6.15 merge window ended just one week ago and there is a month and a half until it will debut as stable, a notable feature has already been queued into a "next" branch for the follow-on Linux 6.16 cycle. For those making use of modern Intel Xeon processors with virtualization, the Trust Domain Extensions (TDX) support for KVM virtualization looks like it will finally be mainlined...

One month after GIMP 3.0 was finally released for this popular image editor ported to GTK3 and many other changes, Pinta 3.0 has now been released. Pinta as a reminder is the open-source image editing program inspired by Paint.NET. With the Pinta 3.0 release the image editor has been ported to GTK4 and libadwaita...

It's been a while since having any exciting feature development to talk about with DragonFlyBSD but merged this past week was dm_target_crypt_ng, a next-generation implementation of their DM-crypt code for disk encryption...

Originally posted back in 2022 were Linux kernel patches for Qualcomm USB audio offloading for Qualcomm SoCs with an audio DSP that can take responsibility for issuing transfers to the USB host controller to free up system resources. After going through 38 rounds of code review the past 2+ years, it looks like Linux 6.16 will finally mainline this Qualcomm USB audio offloading support...

An interesting merge this weekend to the Simple DirectMedia Library (SDL) that is widely-used by cross-platform games and other applications for software/hardware abstractions is Wayland multi-seat support. This addition also comes with a developer working on Valve's Linux graphics efforts...

The Linux 6.16 kernel this summer will likely see the new SNP SVSM vTPM driver introduced for further enhancing the AMD EPYC confidential computing capabilities atop the mainline Linux kernel...

A request for comments (RFC) patch series sent out this week for the Linux kernel is working on the notion of Virtual Swap Space support.

After several ROCm 6.3 point releases, AMD today rolled out ROCm 6.4 as the next update to their open-source GPU/accelerator compute stack and ahead of their big Advancing AI event in June where they will talk about future ROCm work...

So far my testing this week of the Linux 6.15 kernel in its early, post-RC1 state has been going well. No major upsets, yet to uncover any significant performance regressions, and overall has been going smoothly with the many new features/changes in Linux 6.15...

Intel graphics driver engineers today sent out their first batch of feature updates to DRM-Next for queuing ahead of the next Linux 6.16 kernel cycle...

With both Ubuntu 25.04 and Fedora 42 releasing this month you may be curious how these two Linux distributions are competing for performance. Well, it's a very tight race for common Intel/AMD x86_64 hardware. In this article are some benchmarks looking at clean installs of Ubuntu 25.04 and Fedora Workstation 42 on AMD Strix Point.
