A circuit monitors and resets a co-processor. The circuit includes a hang detector module for detecting a hang in co-processor. The circuit also includes a selective processor reset module for resetting the co-processor without resetting a processor in response to detecting a hang in the co-processor.

A method and apparatus provides for the accommodation of display migration among a plurality of physical displays. In one example, the method and apparatus detects a display migration condition from at least a second physical display to a first physical display. The method and apparatus then controls compositing of a plurality of desktop surfaces so as enable access of each one of the plurality of desktop surfaces on the first physical display. The plurality of desktop surfaces include at least a desktop surface associated with the second physical display. The desktop surface is the content in a piece of memory in a frame buffer, which represents all the display content presented on the associated physical display. In one example, the plurality of desktop surfaces may be composited into at least one three-dimensional display object. The three-dimensional display object includes but is not limited to a revolving door object or other three-dimensional shape or object (e.g., a cube object).

A circuit includes a plurality of display path circuits and a timing and frame synchronization circuit. The timing and frame synchronization circuit aligns a first blanking interval of first timing information provided by a first of the display path circuits for a first display based on a second blanking interval of second timing information provided by a second of the display path circuits for a second display.

An apparatus includes a plurality of image processing circuits. Each image processing circuit generates an image frame corresponding to a single large surface. The first image processing circuit provides a portion of the generated image frame for a first display or plurality of displays and provides a remaining portion of the image frame to the remaining image processing circuits. The next image processing circuits provides the remaining portion of the image frame for the next plurality of displays.

Embodiments of a system and method for handling interrupts are described herein. In an embodiment interrupts from various client components in a system (also referred to as clients) are processed by an interrupt handler component uniformly. The various clients signal interrupts in different manners. For example, some clients signal interrupts in a level-based manner, and some clients signal interrupts in a pulse-based manner. In an embodiment, all interrupts received by the interrupt handler are formed into an event message according to a uniform format regardless of the manner in which the interrupt is signaled. The event message includes all information necessary for a host processor interrupt service routine (ISR) to service the interrupts without reading hardware registers. Event messages are stored in an event buffer for access and handling by the host. The event buffer is managed by the interrupt handler.

An apparatus and method utilizes system memory as backing stores so that local graphics memory may be oversubscribed. Surfaces may be paged in and out of system memory based on the amount of usage of the surfaces. The apparatus and method also prioritizes surfaces among different tiers of local memory (e.g. frame buffer), non-local memory (e.g. page locked system memory), and system memory backing stores (e.g. pageable system memory) locations based on predefined criteria and runtime statistics relating to the surfaces. As such, local memory may be, for example, expanded without extra memory costs such as adding a frame buffer memory to allow graphics applications to effectively use more memory and run faster.

An apparatus includes a chrominance and luminance module. The chrominance and luminance module obtains display characteristics of each of a plurality of displays. The chrominance and luminance module selectively adjusts, on a per display basis, chrominance and luminance for each of the displays based on the display characteristics. In one example, the displays collectively display a single large surface.
