A display method for use in multi-operating systems includes: in a host operating system, allocating a native window to each guest operating system; in the guest operating system, requesting a physical continuous memory (PCM) sub-region corresponding to a window from the host operating system when the window is newly created; in the host operating system, allocating the PCM sub-region to the guest operating system; in the guest operating system, storing rendered data to the PCM sub-region when the newly created window is rendered; and in the host operating system, rendering the native window corresponding to the guest operating system based on the data in the PCM sub-region when a display request from the guest operating system is monitored, and in the host operating system, displaying the native window.

Display method for use in multi-operating systems and electronic device

A video display method includes: allocating a native window to each guest operating system; receiving a request for establishing a physical contiguous memory PCM sub-region corresponding to a new window from the guest operating system; allocating a PCM sub-region to the guest operating system, returning a descriptor of the PCM sub-region to the guest operating system, the descriptor being used for instructing a corresponding hardware codec design to write display data into the PCM sub-region; receiving a display request from the guest operating system; and rendering and displaying the native window corresponding to the guest operating system based on the display request and the data in the PCM sub-region.
