Some packages are harder to use, I'll go into details in the following paragraphs.
- Since sched-ext patches have been added to linux-cachyos, you can just use that kernel.
From version 6.12 onwards, sched-ext support is officially available on the upstream kernel. You can use the latest kernel (pkgs.linuxPackages_latest) or our provided CachyOS kernel (pkgs.linuxPackages_cachyos).
First, add this to your configuration:
+Just add this to your configuration:
{
boot.kernelPackages = pkgs.linuxPackages_cachyos;
- chaotic.scx.enable = true; # by default uses scx_rustland scheduler
+ services.scx.enable = true; # by default uses scx_rustland scheduler
}
Then, with the new kernel booted, check if the correct kernel booted:
+Then, reboot with the new configuration, check if the scheduler is running:

If the scheduler is not working for some reason, you can manually start it like:
