One of the most notable changes is that the default kernel is now optimized using AutoFDO. Profiling workloads are run through a diverse set of tests, including sysbench, CachyOS Benchmarker, Git operations, kernel compilation, and several miscellaneous benchmarks. Currently, the profiling is done on a Zen5 machine, but in the future, we plan to support merging multiple profiles for even broader optimization. RustiCL has replaced the default OpenCL driver in the Mesa stack, bringing improved performance and compatibility. Additionally, we now use scx_loader for sched-ext scheduler management in the kernel-manager. This allows for more seamless switching between schedulers and ensures they are properly configured using a dedicated configuration file. We've also enabled Bluetooth support, enhancing the user experience for most users.
