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...

Back in January AMD quietly posted an XDNA Linux kernel driver for enabling the Ryzen AI NPUs. The driver has been maintained within that GitHub repository since but without any clear effort for getting this accelerator driver reviewed and merged into the upstream Linux kernel. Today that first step is finally being taken with the Ryzen AI XDNA Linux kernel driver patches posted to the Linux kernel mailing list and dri-devel to begin facilitating the upstream review process for getting this AI accelerator driver in the mainline kernel...

Last week I published some initial benchmarks of the Amazon/AWS Graviton4 processors now available within the EC2 cloud using the new "R8g" instances. That initial comparison was a 64 vCPU comparison of Graviton4 against AMD EPYC and Intel Xeon 64 vCPU AWS instances. In today's article is a look at the 96-core Graviton4 bare metal performance using the "r8g.metal-24xl" AWS instance type. The Graviton4 r8g.metal-24xl performance was then compared in today's article against various bare metal AMD EPYC, Ampere Altra Max, and Intel Xeon processors in the lab at Phoronix.
It looks like the AMD RDNA4 "GFX12" graphics driver support is in good shape: AMD is now enabling the driver support for the next-generation graphics "out of the box" with the latest pending patches...

With the maturity of the EXT4 file-system it's not too often seeing any huge feature additions for this commonly used Linux file-system but there's still the occasional wild performance optimization to uncover... With Linux 6.11 the EXT4 file-system can see upwards of a 20% performance boost in some scenarios...
Toward the end of 2022 a GCC AArch64 compiler change was quietly made by Arm that allows "-march=native" to be handled on 64-bit ARM by treating it as the equivalent "-mcpu=native" option. The change happened to fly under my radar at that time and didn't draw much attention at large while now it's finally being officially documented in hopes of similar behavior being adopted by other compilers for AArch64...
The ROCm 6.1 series is the latest stable version currently of AMD's open-source GPU compute stack with an increasing large focus on AI. AMD has confirmed to Red Hat that ROCm 6.2 will debut before the release of Fedora 41, so the developers are now hoping to be shipping ROCm 6.2 packages with this upcoming Fedora Linux release...
While Rust is viewed as a memory safe and robust programming language, there is the "unsafe" keyword within Rust that can be used for unsafe code that grants "unsafe superpowers" for the language. As dealing with Rust at low-levels as the Linux kernel can lead to needing to use "unsafe" Rust at times, a documentation standard has been proposed for dealing with such code inside the kernel...
It's been a wild two years since NVIDIA began publishing an open-source Linux GPU kernel driver for Turing GPUs and newer. With the latest NVIDIA 555 Linux driver series that open-source kernel driver support is in great shape and NVIDIA today is out with a lengthy blog post promoting it...
Last week with delivering a number of AMD vs. NVIDIA Vulkan ray-tracing benchmarks under Linux with the current drivers and using the new "Breaking Limit" benchmark, the question was raised how well does AMD's official "AMDVLK" Vulkan driver handle ray-tracing these days compared to the more popular Mesa RADV Vulkan driver used commonly by Linux gamers and as the default driver on most Linux distributions. Here is a fresh look at the RADV versus AMDVLK Vulkan performance on Linux with a focus on ray-tracing performance.
The "x86/bugs" code has been merged for the Linux 6.11 kernel that is just three patches this go around but includes a new Spectre BHI mitigation option...
The EFI changes have been merged for the in-development Linux 6.11 kernel. Notable this cycle on the EFI side is removing support for EFI fake memory maps and then a workaround to get dual GPU support working for some of the older x86-based Apple MacBook Pros by pretending that Apple macOS is booting rather than Linux...
All of the media subsystem feature updates for the in-development Linux 6.11 kernel were sent out overnight. Arguably most notable with the media driver changes for the new kernel is introducing the Raspberry Pi "PiSP" driver for the image signal processor (ISP) found with the Raspberry Pi 5 for powering its camera system...
Wlroots 0.18 recently debuted as the newest version of this Wayland library born out of the Sway compositor project. With wlroots 0.18 is support for new Wayland protocols and other exciting features...
Installing the NVIDIA proprietary graphics driver stack on Fedora currently doesn't jive with UEFI Secure Boot systems and can lead to the OS being unbootable. As such, the NVIDIA driver option was previously removed from GNOME Software. But as the NVIDIA driver is still widely sought after on Fedora by Linux gamers and those wanting to run CUDA/AI workloads especially, Fedora 41 is now cleared to roll-out NVIDIA driver support with UEFI Secure Boot integration...
