摘要： An apparatus and method are described for implementing memory management in a graphics processing system. For example, one embodiment of an apparatus comprises: a first plurality of graphics processing resources to execute graphics commands and process graphics data; a first memory management unit (MMU) to communicatively couple the first plurality of graphics processing resources to a system-level MMU to access a system memory; a second plurality of graphics processing resources to execute graphics commands and process graphics data; a second MMU to communicatively couple the second plurality of graphics processing resources to the first MMU; wherein the first MMU is configured as a master MMU having a direct connection to the system-level MMU and the second MMU comprises a slave MMU configured to send memory transactions to the first MMU, the first MMU either servicing a memory transaction or sending the memory transaction to the system-level MMU on behalf of the second MMU.

摘要： Techniques for managing a three-dimensional (3D) graphics display mode are described. In one embodiment, for example, an apparatus may comprise a processor circuit and a graphics processing module, and the graphics processing module may be operative by the processor circuit to execute a graphics context in a 3D display mode if a 3D-aware graphics context data structure includes an entry corresponding to the graphics context or to execute the graphics context in a non-3D display mode if the 3D-aware graphics context data structure does not include an entry corresponding to the graphics context. Other embodiments are described and claimed.

摘要： Methods, apparatus, and articles of manufacture to provide extended graphics processing capabilities are disclosed. A disclosed example method involves sending a display panel parameter to a shared library module. The display panel parameter is sent by a programmable driver interface in communication between the shared library module and a graphics hardware device driver. The shared library module includes a first graphics processing capability. The graphics hardware device driver includes a second graphics processing capability different from the first graphics processing capability. The example method also involves performing a render operation via the programmable driver interface on a frame buffer based on the first graphics processing capability. The first graphics processing capability is received at the programmable driver interface from the shared library module based on the display panel parameter. The frame buffer is output to a display.

摘要： A computing device including logic at least partially comprising hardware logic to set display modes is disclosed. The logic may be configured to determine if the computing device is closed, and, if so, set the computing device to a single tablet display mode in which the computing device is to render a tablet interface at a first display panel. The logic may be configured to determine if the computing device is open, and, if so, set one of two display modes comprising: a dual tablet display mode in which the computing device is to render a tablet interface at the first display panel and a second display panel; or a laptop mode in which the computing device is to render content at the first display panel and the second display panel is to receive input via a virtual input device.
