DEVICE POWER MANAGEMENT STATE TRANSITION LATENCY ADVERTISEMENT FOR FASTER BOOT TIME

摘要

Methods and apparatus relating to device power management state transition latency advertisement for faster boot time are described. In some embodiments, a storage unit stores a value corresponding to a requisite transition delay period for a first agent to exit from a low power consumption state. The first agent writes the value to the storage unit and a second agent waits for the requisite transition delay period (after the first agent initiates its exit from the low power consumption state) before the second agent attempts to communicate with the first agent via a link. Other embodiments are also disclosed and claimed.

主权项

1. An apparatus comprising:
a wait agent coupled to a storage unit to store a value to correspond to a requisite transition delay period for an exit agent to exit from a low power consumption state, wherein the wait agent is to wait for the requisite transition delay period, in response to the wait agent determining that the exit agent has initiated its exit from the low power consumption state, before the wait agent attempts to communicate with the exit agent via a link.
