Abstract:
Apparatus, systems and methods for handling portrait mode oriented display surfaces without requiring expensive hardware in the display sub-system are disclosed. For example, an apparatus is disclosed such that the rendering of graphics data to the portrait mode display surfaces is redirected at rendering time such that there is no need for adding complicated hardware in the display part of the graphics adapter in order to handle conventional displays—all of which have no circuitry to deal with data natively stored in a portrait mode surface. Additionally, an apparatus to handle direct surface access of a surface through a surface lock which has already been rotated is already described. This can either be done by copying of surface data or by an optimized proposed apparatus which eliminates this copy. Other implementations are also disclosed.
