@ -22,11 +22,49 @@ This configuration will **not** work with MacBook Pro 11,2 or 11,3 models.
## Graphics
The [MacBookPro11,4 and MacBookPro11,5](https://support.apple.com/kb/SP719) models ship with a discrete ATI graphics card (whereas MacBookPro11,2 and MacBookPro11,3 ship with NVidia cards). This is alongside the usual integrated Intel GPU.
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.
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
}
];
};
};
```
## Power management
You may also wish to look into dynamic switching between integrated and discrete graphics, but this config doesn't currently attempt it.
See the removed [hardware.amdHybridGraphics.disable](https://github.com/NixOS/nixpkgs/pull/33915) option for an entry point.
## Hardware probes
Hardware probes generated with `nix run nixpkgs#hw-probe -- -all -upload`:
* Probe [#305905e674](https://linux-hardware.org/?probe=305905e674) of Apple MacBookPro11,5 (with `amdgpu` driver)
DRM (Direct Rendering Manager) snapshots generated with `drm_info -j | curl -d @- https://drmdb.emersion.fr/submit`:
* Snapshot [#e8f8076f1f1b](https://drmdb.emersion.fr/snapshots/e8f8076f1f1b) (with `amdgpu` driver)
