Abstract
A processing system may include a first processing unit for a legacy partition and a second processing unit for a sequestered partition. In one embodiment, a first interrupt handler in the legacy partition may support power management for the first processing unit. A second interrupt handler in the sequestered partition may cause the sequestered partition to take control of power management hardware in the processing system when the legacy partition enters reduced power mode. For example, the second interrupt handler may program the power management hardware to route interrupts to the second processing unit. The sequestered partition may relinquish control of power management hardware to the legacy partition when the legacy partition exits reduced power mode. A power policy manager in the sequestered partition may support features such as wake for incoming communications, wake to record, etc. Other embodiments are described and claimed.
