        The manifaturer/type of the primary system CPU.

        Determines which ucode services will be enabled and provides additional kernel packages.

        cpu type of the host machine.

        The manifaturer/type of the primary system GPU.

        Allows the correct GPU drivers to be loaded, potentially optimizing video output performance.

        If you're on a hybrid system (intel/amd igpu + nvidia/amd dgpu) make sure to use
        the hybrid options, only specifying the dgpu will not work properly.

        Note that if using hybrid-nvidia, you will need to set `hardware.nvidia.prime.nvidiaBusId`
        and `intelBusId` (or `amdgpuBusId`) to "PCI:x:y:z". To find the correct bus IDs, you can
        use `sudo lshw -c display`. Note that you will need to convert the bus ID format from
        hexadecimal to decimal, remove the padding (leading zeroes) and replace the dot with a
        colon (so for example 0e:00.0 -> PCI:14:0:0).

          Should bluetooth be powered on automatically during boot?

          This will worsen the battery life and is not recommended. Instead, you can
          always turn bluetooth on manually once booted, when you need it. Unless you
          have constant need for bluetooth / have some devices to connect to automatically
          you, leave this off.
