Abstract:
One embodiment of the present invention sets forth a method, which includes the steps of detecting the presence of an external graphics subsystem after the external graphics subsystem is attached to the mobile computing device, transmitting a power enable signal to the external graphics subsystem, and activating PCIe signaling channels after having received a ready signal from the external graphics subsystem to enable data communications between the mobile computing device and the external graphics subsystem.
