Abstract:
1. A method in a data processing system for simulating direct frame buffer access, the method comprising: receiving a request for access to a frame buffer memory located in a graphics adapter from an application, wherein direct frame buffer access is unsupported by the graphics adapter; responsive to receiving the request, allocating a portion of system memory for use as the frame buffer memory to form an allocated portion of system memory, wherein the allocated portion of system memory is used in conjunction with existing frame buffer memory located in the graphics adapter, and wherein the system memory is used by an operating system of the data processing system; returning a pointer to the allocated portion of system memory to the application, wherein the application writes data to the allocated portion of system memory, treating the allocated portion of system memory like the frame buffer memory; and sending data in the allocated portion of system memory to a screen memory on the graphics adapter and displaying the data during a selected period of time.
