ABSTRACT:
The invention is directed towards minimizing power consumption in computer systems. One embodiment of the invention is a power management system that is used for a computer system that has at least one device and one power domain. This embodiment uses two different power managers to manage the power consumption of the device and the power domain. Specifically, this embodiment has (1) a first power manager that determines when to change power state of the device, and (2) a second power manager that determines when to change power state of the power domain. Each of these power managers decides to change the power state of its corresponding device or domain based on information from several different sources. These sources can include power-management clients and power managers of related domains or devices.
