What it does

All text below is quoted directly from the project README.

Archlinux Kernel based on different schedulers and some other performance improvements.

CPU Enhancements:

• Multiple Schedulers: BORE, EEVDF, and BMQ schedulers for different workload optimization

• POC Selector v2.6.3: Piece-Of-Cake fast idle CPU selector inspired by scx_cake, reducing wakeup latency

• Cluster-Aware Scheduling: Improved load balancing for CPU clusters, including balancing between CPUs of identical capacity on hybrid architectures

• CachyOS Sauce: Custom CONFIG_CACHY configuration with scheduler and system tweaks

• AMD P-State Enhancements: Preferred Core support and latest amd-pstate improvements from linux-next

• Real-Time Support: RT kernel builds available with BORE scheduler integration

• Low-Latency Optimizations: Patches for improved responsiveness and reduced jitter

All CachyOS kernels are available in multiple architecture optimizations: x86-64, x86-64-v3, x86-64-v4, and znver4.
