Abstract: Examples described herein relate to a graphics processing system that includes one or more integrated graphics systems and one or more discrete graphics systems. In some examples, an operating system (OS) or other software supports switching between image display data being provided from either an integrated graphics system or a discrete graphics system by configuring a multiplexer at runtime to output image data to a display. In some examples, a multiplexer is not used and interface supported messages are used to transfer image data from an integrated graphics system to a discrete graphics system and the discrete graphics system generates and outputs image data to a display. In some examples, interface supported messages are used to transfer image data from a discrete graphics system to an integrated graphics system and the integrated graphics system uses an overlay process to generate a composite image for output to a display.

Abstract: Methods, systems and apparatuses may provide for technology to receive a first video data stream from a first graphics display engine via a first video data channel, receive a second video data stream from a second graphics display engine via a second video data channel, and switch a video output from the first video data stream to the second video data stream based on a switch command to accompany the second video data stream.

Abstract: Embodiments are directed toward apparatuses, systems, and methods to implement policies for dynamically switching between an integrated graphics mode and a discrete graphics mode for providing a display signal to an external USB Type-C port. Some embodiments include a controller configured to provide signals to a first multiplexer and to a second multiplexer, and based on a platform policy, control the at least first or the second multiplexer to dynamically switch to the first graphics mode to output signals received from an integrated graphics controller to the external USB Type-C port or to switch to the second graphics mode to output signals received from a discrete graphics controller to the external USB Type-C port. Other embodiments may be described and/or claimed.
