Intel's Xe Linux Driver Ready With Multi-Device SVM To End Out 2025

Phoronix - Tue, 12/30/2025 - 23:11
Intel's open-source graphics driver engineers are ending out 2025 with a bang. Sent out today was the final drm-xe-next pull request of the year of new feature material ready for the next version of the Linux kernel. Today's pull adds support for SR-IOV scheduler groups as well as multi-device Shared Virtual Memory (SVM) support...

LLVM 22 Lands NVIDIA Olympus CPU Scheduling Model

Phoronix - Tue, 12/30/2025 - 22:46
NVIDIA's Olympus are the ARM64 cores found within the upcoming Vera CPU that will be paired with Rubin. Olympus cores are claimed to be twice as fast as NVIDIA's current CPU cores found in Grace and based on Neoverse-V2. Earlier this year the open-source compilers landed initial support for Olympus while now a proper CPU scheduling model has been upstreamed into LLVM 22...

Linux 6.19 Kernel Benchmarks With X86_NATIVE_CPU Optimization

Phoronix - Tue, 12/30/2025 - 20:27
Added to the Linux kernel earlier this year was the new X86_NATIVE_CPU Kconfig option to enable compiler optimizations for the local/native CPU in use when building the Linux kernel. In effect about ensuring that the "-march=native" compiler flag is set for the kernel build for optimizing the Linux kernel build for your processor being used. Back with Linux 6.16 I ran some benchmarks of the Linux kernel build with X86_NATIVE_CPU to gauge the impact. Now with the current Linux 6.19 kernel and some different hardware, here are some additional on/off benchmarks for evaluating the impact of the Linux kernel build with X86_NATIVE_CPU...

InputPlumber 0.70 Released With Expanded Hardware Support

Phoronix - Tue, 12/30/2025 - 19:55
InputPlumber 0.70 is out today as the newest feature update to this open-source input router and re-mapper daemon for Linux systems. With more gaming handhelds coming to market and other controllers as well as the upward trajectory of Linux gaming, InputPlumber is becoming more applicable for this daemon to combine various input devices into different virtual device formats...

XWayland Gets Patched For Incorrect Pointer Coordinates

Phoronix - Tue, 12/30/2025 - 19:40
An important fix has made it into the X.Org Server XWayland codebase ahead of the new year. XWayland has been fixed to avoid sending incorrect pointer coordinates to X11 clients on pointer enter events...

The Open-Source OpenGL & Vulkan Drivers Enjoyed A Rather Remarkable 2025

Phoronix - Tue, 12/30/2025 - 19:15
The open-source OpenGL and Vulkan drivers making up Mesa had another very successful year. Even with all the years being invested into Mesa largely by Intel, AMD, Valve, Red Hat, and others, the upward trajectory continues for Mesa on expanding the hardware support, punctually adding new Vulkan extensions, and racking up other wins...
