# Nix packages for CachyOS Kernel
|
|
|
|
This repo contains Linux kernels with both [CachyOS patches](https://github.com/CachyOS/kernel-patches) and [CachyOS tunings](https://github.com/CachyOS/linux-cachyos).
|
|
|
|
## Which kernel versions are provided?
|
|
|
|
This repo provides the latest kernel version and the latest LTS kernel version:
|
|
|
|
```bash
|
|
└───packages
|
|
├───aarch64-linux
|
|
├───linux-cachyos-latest
|
|
├───linux-cachyos-latest-lto
|
|
├───linux-cachyos-lts
|
|
└───linux-cachyos-lts-lto
|
|
└───x86_64-linux
|
|
├───linux-cachyos-latest
|
|
├───linux-cachyos-latest-lto
|
|
├───linux-cachyos-lts
|
|
└───linux-cachyos-lts-lto
|
|
```
|
|
|
|
The kernel versions are automatically kept in sync with Nixpkgs, so once the latest/LTS kernel is updated in Nixpkgs, CachyOS kernels in this repo will automatically catch up.
|
|
|
|
The kernels ending in `-lto` has Clang+ThinLTO enabled.
|
|
|
|
For each linux kernel entry under `packages`, we have a corresponding `linuxPackages` entry under `legacyPackages` for easier use in your NixOS configuration, e.g.:
|
|
|
|
- `linux-cachyos-latest` -> `inputs.nix-cachyos-kernel.legacyPackages.x86_64-linux.linuxPackages-cachyos-latest`
|
|
- `linux-cachyos-lts-lto` -> `inputs.nix-cachyos-kernel.legacyPackages.x86_64-linux.linuxPackages-cachyos-lts-lto`
|
|
|
|
## How to use
|
|
|
|
Add this repo to the inputs section of your `flake.nix`:
|
|
|
|
```nix
|
|
{
|
|
inputs = {
|
|
nix-cachyos-kernel.url = "github:xddxdd/nix-cachyos-kernel";
|
|
}
|
|
}
|
|
```
|
|
|
|
Add the repo's overlay in your NixOS configuration, this will expose the packages in this flake as `pkgs.cachyosKernels.*`.
|
|
|
|
Then specify `pkgs.cachyosKernels.linuxPackages-cachyos-latest` (or other variants you'd like) in your `boot.kernelPackages` option.
|
|
|
|
### Example configuration
|
|
|
|
```nix
|
|
{
|
|
nixosConfigurations.example = inputs.nixpkgs.lib.nixosSystem {
|
|
system = "x86_64-linux";
|
|
modules = [
|
|
(
|
|
{ pkgs, ... }:
|
|
{
|
|
nixpkgs.overlays = [ self.overlay ];
|
|
boot.kernelPackages = pkgs.cachyosKernels.linuxPackages-cachyos-latest;
|
|
# ... your other configs
|
|
}
|
|
)
|
|
];
|
|
};
|
|
}
|
|
```
