Scoped User Access In Linux 6.19 To Reduce Speculation Barriers & Its Performance Hit

3 décembre 2025 à 12:29
Merged yesterday to the Linux 6.19 Git codebase was the "core/uaccess" pull that introduces new scoped user-mode access with auto-cleanup functionality. This can reduce the number of speculation barriers encountered when needing to access user-mode memory and thereby avoiding some of the performance penalties incurred by speculation barriers...

openSUSE Begins Rolling Out Intel NPU Support

2 décembre 2025 à 12:21
Via the openSUSE Innovator Initiative, packaging of the Intel Neural Processing Unit (NPU) driver for the openSUSE ecosystem has begun. This is helping to jump-start the Intel NPU support within the openSUSE space although user-space applications ready to leverage the Intel NPU still remains very limited...

AMD GPU Managed Memory Support Merged For The GCC 16 Compiler

1 décembre 2025 à 19:49
When it comes to AMD Radeon/Instinct GPU compiler support much of the emphasis is on the LLVM/Clang compiler stack with their official AMDGPU LLVM shader compiler back-end as well as having the AOMP downstream compiler fork and the like. But the GNU Compiler Collection "GCC" does continue allow targeting AMD GPU targeting with its "AMDGCN" back-end and using the likes of the OpenMP API. It's not too often seeing new AMD GPU activity there for GCC but merged today is now support for managed memory...

Rust Updates For Linux 6.19, Rust Minimum Baseline To Likely Follow Debian Stable
