Abstract
In some embodiments, the invention involves reducing platform power consumption. In an embodiment, the platform may handle a predetermined set of events by the platform firmware when the platform is in sleep, or low power, mode, thereby eliminating the need to wake the processor and utilize the operating system. Other embodiments are described and claimed.
Claims23
A system comprising:
- a processor in a computing platform, the platform capable of transitioning to and from a lower power mode;
- and
- a firmware communicatively coupled to the processor and a chipset, the firmware comprising a boot portion and an event handling portion, wherein the event handling portion is to identify a plurality of wake events to be performed without transitioning the platform to a highest power mode.
A method, comprising:
- receiving a wake event, by computing platform firmware;
- determining a power level of the platform;
- if the determined power level is a low power state, then determining whether the received wake event is to be handled directly by the firmware;
- and
- handling the wake event by one of the firmware and operating system, wherein selection of the firmware and operating system is based on the determined power level and whether the wake event is to be handled directly by the firmware.
2 more elements
A machine accessible medium having instructions that when accessed cause the machine to:
- receive a wake event, by computing platform firmware;
- determine a power level of the platform;
- if the determined power level is a low power state, then determine whether the received wake event is to be handled directly by the firmware;
- and
- handle the wake event by one of the firmware and operating system, wherein selection of the firmware and operating system is based on the determined power level and whether the wake event is to be handled directly by the firmware.
