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: A system, method, and computer program product are provided for distributed processing of overlapping portions of pixels. In use, a plurality of pixels to be processed utilizing a plurality of display processing modules across a plurality of interfaces are identified. Additionally, the pixels are apportioned into a plurality of overlapping portions of the pixels in accordance with a number of the display processing modules and display interfaces. Further, processing of the overlapping portions of the pixels is distributed across the display processing modules and the display interfaces in such way that the portions can be recombined into a single contiguous final image by a plurality display controllers.
