Abstract
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.
Claims20
A method for establishing a link between a source device and a sink device, comprising:
- enabling a hot plug detect (HPD) handler;
- utilizing the HPD handler to receive a HPD interrupt from the sink device 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.
A hardware apparatus for establishing a link between a source device and a sink device, comprising:
- an enable module configured to receive an enable command from the source to enable the hardware apparatus;
- a memory for storing one or more predetermined parameters;
- and
- a control module electrically coupled to the enable module and the memory, the control module configured to receive a hot plug detect (HPD) interrupt from the sink device upon the sink device being coupled to the source device, the control module further configured to apply the one or more predetermined parameters corresponding to the HPD interrupt to establish the link between the source device and sink device;
- wherein the control module adjusts the one or more predetermined parameters if the link between the source device and sink device is not established.
