摘要：
A method and apparatus determines an activity history context for each of a plurality of virtual machines sharing use of a graphics processing core. Each activity history context provides information related to a power setting of at least one engine of the graphics processing core during at least one prior use of the graphics processing core by the corresponding virtual machine. The method and apparatus controls a power setting of the at least one engine of the graphics processing core based on the activity history context corresponding to an active virtual machine using the graphics processing core.
