The framework enables devices to reduce their energy consumption after a specified idle time interval. As part of power management, system software checks for idle devices. The Power Management framework exports interfaces that enable communication between the system software and the device driver.
The Oracle Solaris Power Management framework provides the following features for device power management:
A device-independent model for power-manageable devices.
