发明名称 Single logical screen in X windows with direct hardware access to the frame buffer for 3D rendering
摘要 Single Logical Screen and Direct Hardware Access in a 3D environment are combined by passing a single stream of protocol to the X Server, which in turn passes the information to multiple 3D rendering processes for display on individual screens (monitors). Multiple instances of a single daemon implement the rendering processes. The X Server communicates with an instance of the daemon functioning as a master daemon, which in turn controls the remaining instances functioning as slave daemons. All daemons communicate through common shared memory segments. This achieves both efficiency and performance, since duplicated distribution of commands and data is avoided. Each of the daemons is driven by the contents of the shared memory segments. To facilitate this, an X Client, the X Server and the daemons are all interconnected with separate control and data paths.
