This guide is about setting up NixOS to correctly use your Amd Graphics card if it is relatively new (aka, after the GCN architecture).
Make the kernel use the correct driver early
The kernel can load the correct driver right away (in hardware-configuration.nix):
boot.initrd.kernelModules = [ "amdgpu" ];
XServer
Make sure Xserver uses the `amdgpu` driver in your configuration.nix:
services.xserver.enable = true;
services.xserver.videoDrivers = [ "amdgpu" ];
OpenCL
From 20.09, add this to your hardware-configuration.nix:
hardware.opengl.extraPackages = with pkgs; [
rocm-opencl-icd
];
You should also install the clinfo package to verify that Open CL is correctly setup (or check in the program you use to see if it is now available, such as in Darktable).
Vulkan
Starting from 20.09, the Vulkan drivers can be used:
hardware.opengl.extraPackages = with pkgs; [
amdvlk
];
