I use this machine every day, all day. Ioctls define the external API. Requests from children drivers, generally in the same process, are fulfilled by device protocols corresponding to the device class. If the driver is not able to publish a functional device in bind , for example if it is initializing the full device in a thread, it should publish an invisible device, and make this device visible when initialization is completed.
