Operating system independent network event handling

摘要

Methods and apparatuses for re-instantiating a firmware environment that includes one or more firmware functions available at pre-boot time when transitioning the computing device from a wake state to a sleep state. A network event received by the computing device while in a sleep state may be handled by the firmware environment independent of the operating system and without returning the entire computing device to the wake state.

主权项

1. A computing device comprising:
one or more processors; a filter driver, coupled with the one or more processors, to:
determine hardware transition information related to a transition of a hardware device of the computing device from a first higher power consumption state to a second lower power consumption state, by monitoring input/output (I/O) signals associated with the hardware device that relate to how an operating system of the computing device transitioned the hardware device from the first higher power consumption state to the second lower power consumption state, the hardware transition information comprising information associated with how to transition the hardware device from the first higher power consumption state to the second lower power consumption state; andsave the hardware transition information for access by a firmware module; and the firmware module, coupled with the one or more processors, to:
transition, in response to a wake event, the hardware device to the first higher power consumption state from the second lower power consumption state to allow the hardware device to service the wake event; andtransition, on completion of the servicing of the wake event, the hardware device back to the second lower power consumption state utilizing the saved hardware transition information.
