Title: METHOD AND APPARATUS FOR ACHIEVING FRAME BUFFERING, ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT
Abstract:
Provided in the present invention are a method and an apparatus for achieving frame buffering, an electronic device and a computer program product. The method comprises: determining that a physical frame buffer address corresponding to a display device is mapped to a virtual address of a user space; and in response to a request of a client for acquiring a storage area address corresponding to a virtual frame buffer address thereof, allocating the virtual address to the client, so that the client establishes a mapping relationship between the virtual frame buffer address of the client and the virtual address. By establishing a mapping relationship between the virtual frame buffer address of a client and the virtual address of a real physical frame buffer in a user space, the present invention can send display data running on the client operating system of the client, on the basis of the address mapping relationship, to the physical frame buffer, without the need to allocate a physical storage area to the virtual frame buffer, also eliminating the time and process necessary for copying between storage areas, and therefore the present invention can reduce the occupancy of the main operation system resources and storage resources, improve the performance of the virtualized system, and shorten the execution time needed for the client operation system to display operations.
