Linux 6.19's Significant ~30% Performance Boost For Old AMD Radeon GPUs

Phoronix - Mon, 12/22/2025 - 23:14
For those still using old AMD GCN 1.0 "Southern Islands" or GCN 1.1 "Sea Islands" graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy "Radeon" DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance benefit of now AMDGPU being the default as well as now enabling RADV Vulkan support out-of-the-box.

Rex: Proposed Safe Rust Kernel Extensions For The Linux Kernel, In Place Of eBPF

The upcoming Linux 7.0 kernel (unless it ends up being called Linux 6.20) will drop support for the AMD NPU2 as their second-generation neural processing unit that never ended up being released into any retail products...

NVIDIA's Quest For A "Safe" Linux Kernel For Automobiles, Robotics

Phoronix - Mon, 12/22/2025 - 19:43
NVIDIA engineer Igor Stoppa presented at the Linux Plumbers Conference (LPC) earlier this month around using Linux in safety-critical environments like automobiles and the current shortcomings of the upstream Linux kernel and the challenges on achieving Automotive Safety Integrity Level (ASIL) certifications around the Linux kernel. It's an interesting read/watch around the safety of Linux (or not) for such strict safety environments...
