While the hope remains that GPU resets are a very infrequent task, AMD Linux driver engineers have recently been working on the ability to support a per-queue GC reset capability for more precise reset capabilities when needed...
When it comes to virtualization with the Linux 6.11 kernel, in addition to the latest AMD SEV-SNP code making it upstream, for those making use of VMware virtualization products their initial "VMware Hypercall" API has been merged...
Amazon's Graviton4 server processor that recently went into GA in the AWS cloud is easily the most competitive AArch64 server processor we've seen to date and proving capable of being able to compete with Intel Xeon and AMD EPYC processors across various workloads. Since Graviton4 went GA on AWS earlier this month I've looked at the Graviton4 comparison to other instances at 64 vCPUs and also comparing the Graviton4 96-core metal performance to various Intel, Ampere, and AMD processors. Given the interest in those Graviton4 benchmarks, today's article is another look at Graviton4 looking at the metal performance compared to prior generation Graviton3, Graviton2, and Graviton1 instances for showing just how far Amazon's Graviton processor performance has evolved.
Earlier this month AMD talked more about their Unified AI Software Stack plans for debuting in the coming months to provide a unified software view where AI work can be seamlessly offloaded to Ryzen processors, AMD graphics, or AMD Ryzen AI NPU hardware. Another possible and exciting prospect came to mind when going through the LLVM/Clang 19 changes this week...

This weekend the ASUS ROG Ally X began shipping as an upgraded version of the ASUS ROG Ally handheld gaming console that launched last year. The ASUS ROG Ally X is still powered by the AMD Ryzen Z1 Extreme SoC and for the most part similar to the original model but now with 24GB of LPDDR5X-7500 memory up from 16GB of LPDDR5-6400, twice as large battery capacity, 1TB of NVMe storage rather than 512GB, improved input controls, improved cooling, and other refinements. But it still is running Microsoft Windows 11 out-of-the-box...
Following LLVM/Clang recently dropping support for AMD 3DNow! instructions, the open-source compiler stack is now pushing the MMX SIMD instruction set to a backseat. Moving forward the MMX intrinsics will not make use of MMX but rather be mapped to SSE2. This is all fine unless you are wanting to use this modern code compiler on an Intel Pentium MMX / Pentium II / Pentium III or AMD K6 / K7 processor from the late 90's...
While we have been super eager for the AMD Ryzen 9000 series "Zen 5" desktop processor launch that's been set for 31 July, AMD has issued a last minute delay. Instead the processors will launch in two stages in August...
One of the newest patch series out from AMD this week is on providing I3C HCI driver support for their MIPI I3C IP block found within their latest processors...
Going back two years has been the effort for adding getrandom() to the vDSO in order to enhance the performance. This work has yielded as much as 15x the performance in showing very fast while being secure user-space RNG needs. A few weeks back Linus Torvalds was unconvinced by adding getrandom() to the vDSO, but after going back through the patches he gave it another go. Today the work has managed to be mainlined for Linux 6.11...
Intel today released IGC 1.0.17193.4 as the newest version of the Intel Graphics Compiler that is used for their compute stack on Windows/Linux as well as by their Windows graphics driver for shader compilation...
As a follow-up to last week's AMD Zen 5 overview with the Ryzen 9000 series and Ryzen AI 300 series, today the embargo has lifted on some additional Zen 5 CPU core details.
While not as notable as the nice EXT4 performance optimization making it into Linux 6.11 or features like XFS real-time FITRIM and self-healing Bcachefs on read I/O errors, the Bcachefs, F2FS, and Btrfs file-systems saw smaller updates for the Linux 6.11 kernel cycle...
It's not too often that the ATA pull request for a new Linux kernel merge window has much worth mentioning. With Linux 6.11 there is a change to the kernel defaults worth noting over the default SATA link power management policy. In this case most Linux distributions have been setting a better default themselves and is now a case of the upstream kernel defaults catching up...
The latest video acceleration improvements to report on with the open-source AMD Radeon driver front is support in Mesa 24.3-devel for passing HDR metadata in the AV1 encoder...
The latest printk patches have been submitted and merged for the Linux 6.11 kernel. The printk updates take another step toward the long-in-development work around threaded console printing / non-blocking "NBCON" consoles as the last major step to allow the real-time "RT" kernel patches to land...
Intel's OSPRay ray-tracing engine as part of their oneAPI rendering toolkit continues to serve as a great, scalable and portable RT engine for high fidelity visualizations. With OSPRay 3.2 released today, they continue advancing this open-source engine further...
The upstream Linux 6.11 kernel is making it easier to build a Pacman package of the kernel for use on Arch Linux and other Arch derived distributions relying on Pacman...
Ahead of launch for new discrete/integrated graphics backed by open-source Linux drivers, it can often be difficult to ascertain the level of support pre-launch given the complexity of today's GPUs, we are past the days of long monolithic patch series for new hardware enablement, and also not knowing about what features may be added for the next-generation hardware. But if latest Mesa developer comments hold, it looks like for Intel Xe2 graphics the open-source Vulkan driver at least has "most" of the code now in place...
DRM subsystem lead maintainer David Airlie recently submitted the DRM-Next pull request for merging into Linux 6.11. All of that Direct Rendering Manager (DRM) feature code has landed for the many kernel graphics/display driver updates along with changes to the few AI accelerator "accel" drivers also part of the tree. As usual, the Intel Xe/i915 and AMD AMDGPU/AMDKFD kernel drivers see a bulk of the upstream open-source graphics improvements...

Way back at the start of 2023, French fabless semiconductor company Kalray posted Linux kernel patches for a "KVX" Linux kernel port to get Linux up and running on their MPPA3-80 "Coolidge" DPU SoC with the KV3-1 CPU architecture. A year and a half later this work still is outside the Linux kernel but finally a third iteration of the KVX Linux kernel port has been posted for review...

Back in March were a set of patches to the Linux kernel's XZ embedded compression implementation with the project having switched from public domain to the BSD Zero Clause License along with other changes to update that in-tree code. Since then the notorious XZ backdoor situation was discovered in the upstream XZ project. With those major issues behind, Lasse Collin today sent out an updated set of patches for updating the in-tree XZ code for the Linux kernel...
