摘要: Various systems and methods for managing graphics subsystems are described herein. A system for managing graphics subsystems of a compute device includes a display controller operable to: receive an indication that a first display of the compute device has been activated; enable a power management feature in a display controller, the power management feature to reduce power consumption of the display controller and associated components, and the power management feature to reduce graphics memory bandwidth usage; receive an indication that a second display has been activated with the first display; and maintain the power management feature for at least the first display.

摘要: Particular embodiments described herein provide for an electronic device that includes two or more displays and a BIOS. On startup, before the premem state and MRC initialization of the boot process, the BIOS causes power to be enabled to two or more displays. A display engine determines if a hot plug for each display is asserted and for each display where the hot plug was not asserted, the path to the display where the hot plug was not asserted is closed. In an example, the BIOS communicates the signal to power enable the first display and the second display after general-purpose input/output initialization during the boot process. After the premem stage and MRC initialization are completed, the first display and the second display are both configured to begin to display pixels.

摘要: In one aspect, an apparatus comprises an encoder configured to encode groups of pixels of a video frame into encoded groups. The video frame comprises a plurality of tiles and each of the plurality of tiles comprises one or more of the groups. For each tile in the plurality of tiles: the encoder is configured to generate a notification based on completion of encoding an encoded tile corresponding to the tile. The apparatus comprises a packetizer configured to generate packets corresponding to the video frame simultaneous with the encoding of the video frame by the encoder. For each tile in the plurality of tiles: the packetizer is configured to generate packets from the encoded tile corresponding to the tile based on the notification.
