AMD's Linux graphics driver engineers continue to be busy working on enabling next-generation graphics processors with their upstream open-source driver...

With Ubuntu 23.10 due for release on Thursday, I've been benchmarking a number of systems to look at the Ubuntu 23.10 performance against prior releases like Ubuntu 23.04 and Ubuntu 22.04 LTS. Besides the open-source graphics driver performance for Intel and AMD Radeon graphics always being a stand-out improvement, one area that is particularly exciting with Ubuntu 23.10 is for those with newer AMD processors where there are some nice performance gains to find with this new Ubuntu Linux release. Here are side-by-side benchmarks of an AMD Ryzen 9 7950X desktop along with an Intel Core i9 13900K desktop while testing Ubuntu 22.04.3 LTS / Ubuntu 23.04 / Ubuntu 23.10.

Today Intel software engineers released x86-simd-sort 3.0 and it also comes minutes after OpenJDK merged a modified version of this speeding sorting code into that reference JDK codebase...

This affects Linux distributions of the past two years with the likes of Ubuntu 22.04 LTS, 23.04, Fedora 38, and others vulnerable to this local privilege escalation issue...

The biggest hindrance for using Intel Arc Graphics for Linux gaming has been the lack of Vulkan sparse support as needed for running many newer Windows DirectX 12 games atop Valve's Steam Play with Proton using VKD3D-Proton. Intel recently did implement Vulkan sparse support for ANV in Mesa 23.3 but it only works with their yet-to-be-upstreamed and still-experimental Xe kernel driver. But now Intel Linux graphics driver engineers have managed to pull off a solution for getting the sparse resources supported while using the existing i915 kernel DRM driver...

It was a decade ago that a security researcher commented on X.Org Server security being even "worse than it looks" and that the GLX code for example was "80,000 lines of sheer terror" and hundreds of bugs being uncovered throughout the codebase. In 2023 new X.Org security vulnerabilities continue to be uncovered, two of which were made public today and date back to X11R2 code from the year 1988...

Today the review embargo lifts on the first AMD-powered Framework laptop.
