Kernel Optimizations

To maximize system responsiveness and squeeze every ounce of performance out of the hardware, this configuration utilizes the CachyOS Kernel instead of the mainline NixOS kernel.

Features

• Flake Integration: Pulled declaratively via the nix-cachyos-kernel flake input.
• LTO and x86_64-v3: The pc-angelo host specifically uses the cachyos-latest-lto-x86_64-v3 variant. This kernel is compiled with Link-Time Optimization (LTO) and targeted specifically for processors supporting the x86_64-v3 architecture level (which includes advanced AVX2 instruction sets).
• Scheduling: The CachyOS kernel features advanced CPU schedulers (like BORE) designed for desktop responsiveness.

These kernel-level enhancements drastically improve latency for desktop usage and increase overall frame rates in gaming scenarios.
