Description

CachyOS Addons for Fedora

CachyOS Settings

Settings used in CachyOS, including modprobe configurations and udev rules, specifically packaged and optimized for Fedora.

GitHub CachyOS-Settings.

scx-scheds and scx-tools

The scx-scheds package provides various sched-ext (BPF) schedulers. scx-tools includes scxctl for managing and monitoring these schedulers.

GitHub scx-scheds.

scx-manager

A simple and intuitive GUI for managing and switching between different sched-ext schedulers via scx_loader.

GitHub scx-manager.

Ananicy-cpp

An auto-nice daemon with CachyOS-specific rules to improve system responsiveness by automatically adjusting process priorities. Note: After further development of the sched-ext schedulers, it is usually okay to use alongside them, but can be disabled as a troubleshooting step if instability occurs.
