But for those looking at achieving even greater out-of-the-box Linux performance on Intel Panther Lake, the Arch Linux based CachyOS does a pretty fine job at further advancing the performance.

Following an April Fools' Day tease of Gentoo claiming they were going to switch to GNU Hurd as their primary kernel moving forward, they have now acknowledged the joke but in fact also announcing there are now experimental Gentoo GNU/Hurd images available.

With Linux 6.19 AMD GCN 1.1 and GCN 1.1 dGPUs now default to the AMDGPU driver rather than the legacy Radeon Linux driver. For these Southern Islands and Sea Islands graphics cards it means much better performance, RADV Vulkan support out-of-the-box, and other improved functionality in using this modern AMDGPU kernel graphics driver on Linux. One of the exceptions has been the GCN 1.1 APUs like Kaveri still defaulting to the older Radeon driver but a patch has been volleyed to make that change.

Meta's great Linux engineering team have been working through some fresh performance optimizations recently from optimizing /proc/interrupts outputs to renewing their investment in jemalloc.
