Linux Hardware Reviews & Performance Benchmarks, Open-Source News

Timur Kristóf of Valve's Linux graphics driver team is the one that worked on improving the old AMD Radeon GCN 1.0/1.1 graphics card support by making AMDGPU driver improvements so it could become the default for these Southern Islands and Sea Islands GPUs rather than the legacy Radeon kernel driver. That meant better performance, RADV Vulkan support out-of-the-box, and other benefits. More recently he finished AMDGPU improvements for Kaveri and other GCN 1.1 era APUs. Now Timur's out with some more fixes for helping select GCN 1.0 hardware.

The sound subsystem changes were merged this week for Linux 7.1 that include some new hardware support and other useful additions.

The popular Arch Linux based CachyOS has now rolled out the Linux 7.0 kernel to its users. But beyond re-basing against the latest upstream kernel version it is also carrying some extra patches.

With the set of today's AMDGPU kernel graphics driver Display Core (DC) patches is a rather curious addition with wiring up the Linux code to a "power module" that looks like it will better match Microsoft Windows behavior with the AMD Radeon driver around display-related power savings features.

The Linux 7.1 kernel is bringing performance improvements for Sheaves, the per-CPU caching layer introduced several kernel cycles ago (Linux 6.18) for better efficiency on today's high core count hardware. Sheaves began as an opt-in feature but since Linux 7.0 is now being used for all caches.

The SDL library widely used by cross-platform games and part of the Steam Runtime has now established a policy to block code contributions made using AI / Large Language Models (LLMs).

The workqueue changes merged today for the Linux 7.1 kernel are significant for today's modern high-end processors where there can be many CPU cores per last level cache (LLC / L3 cache).

Last month I ran benchmarks showing the very positive performance impact FRED has on Intel's new Panther Lake processors while wondering why Flexible Return and Event Deliver wasn't enabled by default yet on Linux. Hours after that story was published, an Intel engineer posted the patch to enable FRED by default with the rationale they were waiting for hardware to be publicly released in order to evaluate the performance benefit. Days after that the FRED-by-default patch hit tip/tip.git and now as of yesterday that patch is merged for Linux 7.1.

Code now merged for the Linux 7.1 kernel may provide some negative performance implications for those still running modern Linux kernels on 32-bit hardware. A fundamental change can present cache line alignment and slab sizing implications for 32-bit Linux OS users but will provide for cleaner code with modern 64-bit computing.
