AMD AOMP 23.0-0 was released overnight as the latest build of this LLVM/Clang downstream that continues to carry the very latest AMD patches focused on delivering the best support for GPU offloading to Radeon/Instinct hardware with the likes of the OpenMP and OpenACC APIs. AOMP continues to serve as a great leading-edge compiler for the best AMD GPU offloading experience until the patches ultimately work their way into upstream LLVM...

This week marked the release of KDE's Plasma 6.6 desktop as a very successful release that overall is in very robust shape and performing well. While Plasma 6.6 overall is in great shape, there are various bugs - including crash fixes - that have already been queued for the upcoming Plasma 6.6.1. KDE developers are also quite busy on the trek toward Plasma 6.7...

As some good news out of Intel today on the Linux/open-source side following last year's layoffs, they're hiring for some new Linux software development roles -- including for enhancing their Linux graphics driver stack that also includes a focus on Linux gaming with the likes of Valve's Proton (Steam Play)...

Drgn is the programmable debugger developed by Meta engineer Omar Sandoval that has proven quite versatile and popular with Linux kernel developers and others. After nearly two dozen releases already, Drgn v0.1 was released this week as another big step forward for this open-source debugger...

When beginning some early Linux 7.0 kernel benchmarking this week for looking at its performance in its early development state, I started off testing on Core Ultra X7 "Panther Lake" in being hopeful for better performance with the maturing Arc B390 Xe3 graphics and the like. But I ended up finding Intel Panther Lake seeing some performance regressions on Linux 7.0. So next up I turned to an AMD EPYC Turin server since if regressions existed there at least it's much faster to carry out bisecting of the kernel performance regressions. But with that initial testing wrapped up, I didn't find any regressions like with Panther Lake and standing out were some rather enticing PostgreSQL database server performance benefits when running atop Linux 7.0.

Following GNOME 50's Mutter merging sdr-native color mode support for wide color gamut displays this week, another late addition to Mutter has now been merged ahead of next month's GNOME 50 stable release...

Last year LunarG announced KosmicKrisp as a new Vulkan implementation atop Apple's Metal API. Initially targeting macOS, KosmicKrisp since was merged to Mesa and has evolved quite nicely as a modern implementation of Vulkan-on-Metal for Apple Silicon. It continues moving ahead with an eye for iOS, more performance optimizations, and completing Vulkan 1.4 support...

All of the Thunderbolt/USB driver changes were merged this week for the nearly-over Linux 7.0 merge window...

It's not too surprising but the upcoming Ubuntu 26.04 Long Term Support release will be transitioning to OpenJDK 25 as its default Java version...

Merged today to Mesa 26.1 Git is a one-line change to the Intel "ANV" Vulkan driver that is showing to deliver some slight performance benefits or up to 3% noted in some select games...

The Turbostat command-line utility for reporting processor frequency and idle statistics along with other useful information for AMD and Intel CPUs can now report some L2 cache stats for recent Intel CPUs beginning with Linux 7.0...

Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to QEMU...

The Gigabyte MZ33-AR1 is a single socket AMD EPYC 9004/9005 E-ATX server motherboard for those wanting up to 24 RDIMMs, dual 10 Gigabit LAN, and plenty of storage potential via six MCIO connectors and four PCIe Gen5 x16 slots. Beyond offering nice capabilities for this modern AMD EPYC server motherboard at a ~$700 USD price point, it's uniquely positioned for an open-source firmware future thanks to ongoing work around AMD openSIL and hopefully followed by OpenBMC.
