ABSTRACT:
A method, apparatus and system enable enhanced processor frequency governors to comprehend virtualized platforms and utilize predictive information to enhance performance in virtualized platforms. Specifically, in one embodiment, an enhanced frequency governor in a virtual host may run within a virtual machine on the host and interact with a virtual machine manager to collect predictive information from application(s) running within each virtual machine on the host. The enhanced frequency governor may then utilize the predictive information to determine future CPU frequency requirements and raise or lower the CPU frequency and/or voltage in anticipation of the needs of the various applications.
