Abstract: In examples, a virtual channel allocated to a virtual machine may be used to transmit image data representing a display surface to memory assigned to the display surface in a virtual address space of the virtual machine. A physical display engine may be configured to fetch the image data from the memory, perform desired transformations, and send the resulting output to the display surface to display. Privileged software may process requests from virtual machines for allocations or configurations of display surfaces and configure the physical display engine, a memory system, and/or other system components accordingly. Software running on a virtual machine may use virtual channels to submit the requests and transmit image data for display surfaces to memory using the virtual address space. A virtual channel may be provided by a virtual network adapter assigned to the virtual machine.

Abstract: Various embodiments disclose a system that includes a first source processor that generates a first stream of graphics data, a second source processor that generates a second stream of graphics data, a display device that displays at least one of the first stream of graphics data and the second stream of graphics data, and a timing controller that is coupled to the first source processor and the second source processor and receives a first control signal to enter into a self-refresh state, in response, enters into the self-refresh state, causes the display device to display a first frame stored in memory, wherein the first frame includes at least a portion of data included in the first stream of graphics data, receives a second stream of graphics data, exits the self-refresh state, and causes the display device to display the second stream of graphics data.
