METHOD, APPARATUS, AND SYSTEM FOR ENERGY EFFICIENCY AND ENERGY CONSERVATION INCLUDING NON FRAME AWARE FREQUENCY SELECTION

摘要

Systems and methods of adjusting a frequency of a graphics controller may include a logic to determine a metric associated with an input/output (I/O) queue. The metric may be used to determine whether an I/O limited condition exists. The I/O limited condition may be associated with a graphics controller. There may be a logic to cause a frequency of the graphics controller to be decreased when the I/O limited condition exists, and a logic to cause the frequency of the graphics controller to be increased when the I/O limited condition does not exist. The I/O limited condition may exist when a magnitude of the metric is equal to or greater than a first threshold. The I/O limited condition may not exist when the magnitude of the metric is equal to or less than a second threshold.
