There has been a lot of talk the past few days over the AMD AGESA PI 1.2.0.2 update that has begun rolling out to AMD AM5 motherboards with BIOS updates. The AGESA 1.2.0.2 is said to improve inter-core latency for Ryzen 9000 "Zen 5" processors when cores from different CCDs are cross-communicating. Some -- at least under Windows -- have reported performance improvements and thus several Phoronix readers have requested I run some of my tests with AGESA 1.2.0.2. Here are said comparison benchmarks using an AMD Ryzen 9 9950X on Ubuntu Linux.

A patch was sent out on Sunday for adding new Linux kernel configuration options for tuning the kernel build to different x86_64 micro-architecture feature levels. The intent is on generating kernel builds that are faster for use on modern Intel and AMD systems. However, this patch is likely to not be accepted in the mainline kernel and has already been criticized upstream Linux kernel developers...

The file structure is one of the most widely-used data structures by Linux kernel drivers. The file struct represents an open file and thus obviously very important and ubiquitous throughout the kernel. With the Linux 6.12 kernel the file struct has been adjusted so it's smaller than before and in turn could help with performance for file-heavy workloads...
