@@ -24,19 +24,34 @@ This configuration will **not** work with MacBook Pro 11,2 or 11,3 models.
The [MacBookPro11,4 and MacBookPro11,5](https://support.apple.com/kb/SP719) models ship with a discrete ATI/AMD graphics card (whereas MacBookPro11,2 and MacBookPro11,3 ship with NVidia cards). This is alongside the usual integrated Intel GPU.
You may wish to look into dynamic switching between integrated and discrete graphics, but this config doesn't attempt it.
To switch from the older `radeon` driver to the newer `amdgpu` driver (via experimental `si_support`), include `nixos-hardware.nixosModules.common-gpu-amd-southern-islands` (or `${nixos-hardware}/common/gpu/amd/southern-islands`) in your configuration. This will get you vulkan support among other benefits.
Currently this uses the experimental `si_support` to disable the older radeon driver and enable the more modern `amdgpu` driver.
For example, in your `flake.nix`:
```nix
nixosConfigurations = {
macbook-pro-11-5 = lib.nixosSystem {
system = "x86_64-linux";
modules = [
nixos-hardware.nixosModules.apple-macbook-pro-11-5
nixos-hardware.nixosModules.common-gpu-amd-southern-islands
{
# Your personal configuration
}
];
};
};
```
