ABSTRACT:
A method, data processing system, and computer instructions for simulating direct frame buffer access. A request for access to a frame buffer memory is received from an application. A portion of system memory is allocated for use as the frame buffer memory in response to receiving the request. A pointer to the portion of system memory is returned to the application. The application writes data to the portion of system memory, treating the portion of system memory like the frame buffer memory.
