This raises two more questions. 1. Booting It is possible that our only display and, worse, our source of power is a display that can be used only in an alternate mode and is connected via a type C connector. We need some kind of boot time support for alternate modes. The firmware will surely want to display something. So it is possible that we start the OS will a valid power contract. How do we deal with that? Renegotiate? 2. Multiple GPUs How do we know which GPU is connected to which port?
