Abstract
Methods and apparatuses to create and manage volatile graphics objects in a video memory are disclosed. An object is created and marked as volatile. The volatile object is stored in a video memory of a graphics subsystem. A volatile marking indicates that data for an object is not to be paged out from the video memory to make room for other data. The video memory space occupied by the volatile object is indicated as a volatile storage, in a data structure. Another object is written into at least a portion of the video memory space, which is occupied by the volatile object, without paging out data for the volatile object. In one embodiment, at least a portion of the volatile object is referenced or used while another object is formed. The volatile object may be discarded after being referenced or used to form another object.
