X.Org package wrangler Alan Coopersmith at Oracle announced today the release of imake 1.0.11, the newest version of this utility that 20+ years ago was used extensively as part of the X Window System build process for generating Makefiles from a template. With this first imake point release in two years, imake itself can now be built via Meson and there is now support for RISC-V and LoongArch architectures...

Some Meaningful Performance Benefits For Clang + LTO Built Linux Kernels

Phoronix - Wed, 12/31/2025 - 02:50
Over the past few years building the Linux kernel with Clang has matured a lot thanks to upstream improvements to both LLVM/Clang and the Linux kernel. As it's been a while since our last comparison for GCC vs. Clang built kernels on the resulting system performance, our latest year-end 2025 benchmarking is providing a fresh look at the Linux 6.19 upstream Git kernel built under the latest stable GCC 15 and LLVM Clang 21 compilers. Plus with the Clang-built kernel is also the option of the Link-Time Optimized (LTO) kernel for even greater performance.

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

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...
