  • Method & apparatus for a power management pseudo-device driver
    Patent number: 5655126
    Abstract: A power management system for conserving power in a computer system that runs the UNIX.RTM. operating system. The power management system comprises a power management pseudo-device driver, power management compatible device drivers for power manageable hardware devices, and additions to the Device Driver Interface and Driver Kernel Interface (DDI/DKI) layer. Each power management compatible device driver maintains last access times for its associated hardware device components. The power management pseudo-device driver periodically checks the last access time for all the power manageable hardware device components in the computer system. If the power management pseudo-device driver determines that a hardware device component is idle, the power management pseudo-device driver instructs the idle hardware device's associated device driver to reduce power to the idle hardware device component.
