Iris

To use the new Gallium iris driver, you can use the following in your system configuration:

hardware.opengl.package =
  (pkgs.mesa.override {
    galliumDrivers = [
      "r300" "r600" "radeonsi" "nouveau" "virgl" "svga" "swrast"
      "iris"
    ];
  });

Note that you might want additional entries in extraPackages, for example, to enable "accelerated video playback".
