Abstract
Information is provided to a source device during link training regarding the state of a remote link when an intermediate device using a different protocol is connected between source and sink devices. The intermediate device includes two controllers connected by a cable, the first controller being connected to the source device and the second controller being connected to the sink device. State information regarding the remote device may be provided by a state machine that stores data to a register on the intermediate device. Based on the state of the remote link, the source device is able to generate a representation of the end to end link between the source and sink device, and to perform link training accordingly.
