Systems and methods for hot-plug detection recovery
One embodiment is a method for establishing a link between a source device and a sink device. The method comprises enabling a hot plug detect (HPD) handler in the source device, utilizing the HPD handler to receive an HPD interrupt upon the sink device being coupled to the source device, applying one or more predetermined parameters corresponding to the HPD interrupt to establish the link between the source device and the sink device, and adjusting the one or more predetermined parameters if the link between the source device and the sink device is not established.
