Abstract:
In some embodiments, the invention involves a system and method relating to managing power utilization in partitioned systems. In at least one embodiment, the present invention is intended to control the sleeping/wakefulness of devices, as necessary, to minimize power utilization of devices whose accesses are routed away. Inter-partition communication is used to utilize devices in a sequestered partition while devices in the OS partition are put into a sleep state to save power. Other embodiments are described and claimed.
