Modified sleep state graphics processing system
A modified sleep state graphics processing system includes a graphics processing system coupled to a central processing system that is configured to enter different sleep states. A power management engine coupled to the graphics processing system and the central processing system determines that the graphics processing system is operating above a graphics processing activity threshold and, in response, prevents the central processing system from entering a first subset of the different sleep states. The central processing system is configured to communicate with the graphics processing system to cause the graphics processing system to render graphics while prevented from entering the first subset of the different sleep states. The power management engine may then determine that the graphics processing system is operating below the graphics processing activity threshold and, in response, allow the central processing system to enter the first subset of the different sleep states.
