Abstract:
1. A method of managing power consumption in a computing device, the method comprising: computing, at a first power manager of the computing device, a power state for a power management member; sending instructions, from the first power manager to a first power-controlling driver, to change a power state of the power management member based on the computed power state of the power management member; from the first power manager, sending the computed power state of the power management member to a second power manager; computing, at the second power manager, a power state for a power domain based on the computed power state of the power management member received from the first power manager, wherein the power domain supplies power to the power management member; and sending instructions, from the second power manager to a second power-controlling driver, to change a power state of the power domain based on the computed power state of the power domain.
