Two years ago DreamWorks Animation open-sourced their MoonRay renderer that is an award-winning, state-of-the-art production MCRT renderer used for a number of feature films. Since then they have continued advancing this open-source code as OpenMoonRay and adding more features. The newest feature release of OpenMoonRay is now available with yet more capabilities for this impressive renderer...

Sound Open Firmware 2.13 debuted today as the newest feature update to this open-source audio DSP stack started by Intel. With Sound Open Firmware 2.13 comes support for new Intel platforms and other enhancements...

On top of announcing today the AMD Instinct MI350 series, ROCm 7.0, and introducing the AMD Developer Cloud, AMD also teased the next-generation Instinct MI400 / Instinct MI450 series coming in 2026...

What will likely be one of the most under-reported announcements from AMD AI Day 2025 is the AMD Developer Cloud... It's set to play a big role moving forward but today isn't as exciting itself as the likes of the Instinct MI350 series and ROCm 7.0 software...

Following the Red Hat Enterprise Linux 10.0 release going GA in May, Rocky Linux 10.0 is now available as this free alternative to RHEL 10...

Alongside announcing the AMD Instinct MI350 series at their AI day, ROCm 7.0 was also introduced and will be available today in preview form...

While OpenZFS 2.3 has been stable for several months, for those still relying on the OpenZFS 2.2 series there is a new stable point release...

AMD at its Advancing AI Day event in San Jose announced the Instinct MI350X and MI355X accelerators. Exciting open-source fans will be that the Instinct MI350 series features fully open-source driver support and that is already mainline within the Linux kernel...

Merged yesterday for Mesa 25.2 is an exciting change for those still making use of vintage Radeon GPUs... OpenGL 4.6 support is now exposed for the Radeon R600g Gallium3D driver...

While the AMD Ryzen AI Max+ PRO 395 and Ryzen AI Max+ 395 are very similar processors just as the Ryzen PRO processors are to other non-PRO parts, one of the differences with the AMD PRO Technologies come down to AMD Memory Guard providing full system memory encryption. From the HP BIOS with the ZBook Ultra G1a there is a convenient toggle for this full memory encryption support and thus I decided to carry out some benchmarks to measure the performance cost to this memory encryption feature on this AMD Strix Halo SoC.

Back in April I published Linux benchmarks of the Lenovo ThinkPad T14s Gen 6 with the AMD Ryzen AI 7 PRO 360 SoC. Some follow-up benchmarks I did back then that I have been meaning to publish is looking at the ACPI Platform Profile impact on performance and power for this ThinkPad laptop under Linux. Here are those numbers...

Over the past month I have been testing out the HP ZBook Ultra G1a powered by AMD Ryzen AI Max+ PRO Strix Halo. Simply put: WOW! I don't remember the last time I have been so fascinated by a laptop SoC from its incredible performance generationally and even compared to existing AMD SoCs within the Ryzen AI 300 series and outright dominating against the Intel Lunar Lake for its Xe2 integrated graphics. The HP ZBook Ultra G1a thanks to AMD Strix Halo offers an incredibly potent integrated GPU and allowing up to 16 cores / 32 threads offers immense CPU performance too. HP packages Strix Halo up into a very well built, mobile workstation oriented laptop design to create an amazing laptop. It's a reliable laptop with captivating performance but does carry a high price tag but with good Linux support too except for one caveat.

PCI Express 7.0 was announced back in 2022 as coming in 2025 with 128 GT/s Since then draft specifications were published while today PCI-SIG is announcing the formal PCI Express 7.0 specification release along with a new PCIe Optical Interconnect Solution...

DAMON is a nifty data access monitoring solution for the Linux kernel developed by Amazon and other parties for system monitoring and performance/efficiency optimizations and more. But it's not so ground-breaking that it's worth enabling by default in all Linux kernel builds, Linus Torvalds has decided...

The Ultra Ethernet Consortium today published the UEC Specification 1.0 release. Nearly two years ago the Ultra Ethernet Consortium was started by Intel, AMD, Meta, HPE, and others and hosted by the Linux Foundation for open and high performance networking with an emphasis on AI and HPC...

With the HP ZBook Ultra G1a Strix Halo laptop sporting the AMD Ryzen AI Max+ PRO 395 with Radeon 8060S Graphics it offers incredible performance potential as shown in my many benchmarks over the past month on Ubuntu Linux. But if wanting to push the Ryzen AI Max even further, with performance-optimized Linux distributions like CachyOS and Intel's Clear Linux it's possible to tap some additional performance out of this 16-core Zen 5 laptop.

DragonFlyBSD has updated its Direct Rendering Manager (DRM) kernel graphics/display driver code that it ports over from what's available in the upstream Linux kernel. The latest revision to the DragonFlyBSD kernel graphics driver code enables support for some new hardware platforms but remains woefully behind the latest generation dGPUs/iGPUs and what is found in the upstream Linux kernel...

In late May the Rust-written "Rusticl" OpenCL driver within Mesa landed support for Shared Virtual Memory (SVM). Following that, the Intel Iris Gallium3D driver has now seen its support merged for SVM...

With less than one year to go until the Ubuntu 26.04 LTS release and trying to get any major changes into Ubuntu 25.10 for extra baking, Ubuntu engineers have been evaluating some Ubuntu Server seed changes...

With AMD continuing to be focused on their AMDGPU LLVM compiler back-end for their GPU compiler needs from compute to graphics shaders, the AMD GPU/accelerator hardware support within the GNU Compiler Collection "GCC" has long taken a backseat and left to third-party firms to implement. Posted today was an experimental patch providing very early support for the AMD Instinct MI300 series hardware with the GCC compiler...
