Abstract: A display simulation system is provided having a flexible design for emulating and/or supporting any number of display types and/or display standards. The display simulation system may include one or more reference drivers that include a virtual graphics processing unit (GPU) and one or more virtual frame buffer drivers. In one embodiment, the display simulation system may implement a virtual display in response to a user selection input. For instance, the user selection input may initiate a simulated hot-plug event on the display simulation system. Based upon the user selection, an appropriate display profile corresponding to the selected display type or standard may be loaded by the display driver. In this manner, the display simulation system may provide for user interaction with the virtual display, such as for testing, verification, benchmarking, or development purposes.

Abstract: Methods and apparatus for managing power of a computer system. Access to a device by a process that accesses the device but does not require user interaction to continue running is prevented during power management and when the device is powered off. Memory space is allocated in the computer system prior to the device being powered off. All access to the device is directed to the allocated memory space during the power management period.

Abstract: A computer graphics system that utilizes a super-sampled sample buffer and a sample-to-pixel calculation unit for refreshing the display. The graphics system may have a graphics processor, a super-sampled sample buffer, and a sample-to-pixel calculation unit. The graphics processor renders samples into the sample buffer at computed positions or locations in the sample buffer. The graphics system may utilize a window ID that specifies attributes of pixels on a per object basis. The window ID may specify one or more of a sample mode, filter type, color attributes, or source attributes. The sample mode may include single sample per pixel mode and multiple samples per pixel mode. In implementing a single sample per pixel mode, the graphics system may be further operable to generate a single sample per pixel for certain windows of the screen in order to, for example, provide backwards compatibility with legacy systems with no multi-sampling support.
