Abstract
The present invention is generally directed to a system and method for managing context information in a graphics system having multiple displays configured as a single logical screen (SLS). In accordance with one embodiment a system is provided comprising a single device driver coupled to directly communicate with display hardware of at least two displays, a graphics API (application program interface) for communicating graphics information to the single device driver, a memory configured to store context information, the memory in communication with the single device driver, and a mechanism configured to direct context data from the memory to the display hardware of one of the displays.
Claims13
A system for managing context information in a graphics system having multiple displays configured as a single logical screen (SLS) comprising:
- a single device driver coupled to directly communicate with display hardware of at least two displays;
- a graphics API (application program interface) for communicating graphics information to the single device driver;
- a memory configured to store context information, the memory in communication with the single device driver;
- and
- a mechanism configured to direct context data from the memory to the display hardware of one of the displays.
In a graphics system having multiple displays configured as a single logical screen (SLS), a method for managing context information comprising:
- determining which one of the multiple displays that a majority of a window occupies;
- directing context information from a memory into display hardware associated with the display that a majority of the window occupies.
A system for managing context information in a graphics system having multiple displays configured as a single logical screen (SLS) comprising:
- a single device driver coupled to communicate directly with display hardware of at least two displays;
- and
- a graphics API (application program interface) for communicating graphics information directly to the single device driver, and without communicating the graphics information through an intervening process.
