Back in May a big patch series was published for reworking the Linux kernel to make the SMP support unconditional. Right now those that happen to be running Linux in a uniprocessor (1 CPU core) configuration can build with "CONFIG_SMP" disabled but the proposed patches would make symmetric multi-processing support always present. Those patches took a step forward this week and could be merged for the Linux 6.17 cycle later in the summer...

The X.Org Server has been seeing a lot of commits this week... to revert bad code...

Prominent AMD Mesa developer Marek Olšák this week landed a number of fixes for the RadeonSI Gallium3D driver code in working to enable medium precision "mediump" support for this open-source graphics driver...

Linux 6.15 mistakenly shipped with a nasty power regression for some systems, such as those relying on the "nosmt" option to disable Simultaneous Multi-Threading / Hyper Threading. That idle power regression was fixed for Linux 6.15.2 and Linux 6.16 Git by reverting the troubled patch that introduced the regression. Now merged ahead of Linux 6.16-rc2 is a proper fix for that problematic patch so it could be re-merged without the power fallout...

Sasha Levin just sent out an initial "request for comments" patch series for the Linux kernel in aiming to establish a Kernel API Specification Framework...

Back in April at Google Cloud Next was the introduction of the new C4D family of VMs powered by AMD EPYC 9005 "Turin" processors. Back on launch day I looked at the C3D vs. C4D performance at some of the smaller, more common VM sizes. In today's article is a look at the top-end performance of the C4D family with 384 vCPUs. For those wondering about the compute potential of the c4d-standard-384, here are some benchmarks of this 192-core / 384-thread EPYC Turin configuration compared to the prior C3D AMD EPYC Genoa based instance that topped out at 360 vCPUs.

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...

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.

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...

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.

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...

The Linux 6.15 kernel cycle started off a bit rough with a heavy hitting performance regression spotted and then fixed but to only then discover another Linux 6.15 performance regression affecting modern AMD CPUs. Fortunately those issues were cleared out in time for the recent Linux 6.15 stable release. Linux 6.15 stable is looking good especially on 5th Gen AMD EPYC "Turin" servers with some recent benchmarks showing some modest gains over the Linux 6.14 kernel.

On the GNOME Foundation blog today is an interesting post how Amazon Web Services (AWS) has ended up sponsoring and powering all of the GNOME web infrastructure...
