Abstract: An electronic device selectively couples a head with links in a graphics processing unit to a currently selected display port in a pair of display ports. During operation, control logic in the electronic device monitors a pair of configuration signals from the pair of display ports, where the pair of configuration signals correspond to physical connections to the pair of display ports. Then, the control logic determines a selection control signal based on the monitored pair of configuration signals, a policy setting and a default display port, where the selection control signal specifies the currently selected display port. Moreover, the control logic provides the selection control signal to a multiplexer in the electronic device. Next, the multiplexer selectively couples the head with the links in the graphics processing unit to the currently selected display port based on the selection control signal.

Abstract: Systems and methods are disclosed to enable switching of graphics processing unit (GPU) resources based on different factors. Embodiments include a virtual graphics driver as an interface between GPU drivers and the applications or graphics framework executing on an electronic device. The virtual graphics driver may switch GPU resources from a first GPU to a second GPU by routing function calls to the first GPU or the second GPU. The switching of GPU resources may be based on power management, system events such as hot-plug events, load management, user requests, any other factor, or any combination thereof. In some embodiments, a virtual frame buffer driver is provided that interfaces with the frame buffer of the GPU and provides a virtual view of the frame buffer to manage additional system application programming interfaces (APIs) during the switch.
