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. There’s one of the AMD Framework laptops in the lab for Linux testing and benchmarking but unfortunately no review for launch day due to being held up by a BIOS regression and thus unable to properly utilize accelerated graphics until a new BIOS revision is made available in the coming days…

As written about last month, AMD Linux engineers have been working on PMF Linux driver support for a “Smart PC Solutions Builder”. The AMD Smart PC Solutions Builder feature is intended to provide OEMs with more control over system power/performance policies. It looks like systems making use of this feature are already to the marketplace or imminent with AMD having already landed the PMF firmware…

Checking for the presence of Intel virtualization (VMX) support and it being enabled can be easily achieved by looking at the flags in /proc/cpuinfo. But to this point AMD virtualization (SVM) has always been shown to user-space via /proc/cpuinfo even when the BIOS/platform has disabled SVM functionality. Finally for Linux 6.7 this oversight is being corrected…

The past several Linux kernel cycles has seen Loongson engineers working on implementing more kernel features for LoongArch, the MIPS-derived and RISC-V-inspired architecture out of China for domestic PCs. The performance of LoongArch CPUs so far still aren’t competitive to x86_64 or Arm hardware but at least slowly are becoming more practical with more features being wired up. The latest milestone is the Kernel-based Virtual Machine (KVM) virtualization support appearing ready ahead of Linux 6.7…

Several months back was work to disable all Microsoft Remote Network Driver Interface Specification (RNDIS) drivers in the Linux kernel on the basis of being insecure and other factors. That plan of disabling the RNDIS drivers was faced by opposition around concerns of potentially disrupting USB tethering support and the like. It’s been months since hearing anything about updated plans for disabling or dropping the RNDIS drivers but the Git branch was updated today for disabling this class of drivers…
