Method, apparatus and system for determining an interface during a power state transition

摘要

Techniques for determining a communication interface of a computer platform. In an embodiment, a power management unit of a computer platform provides to an agent of the platform an indication of a power state. In certain embodiments, the agent determines, based on the indication of the power state, that an interface is expected to be available. The agent may designate information for transmission via the first interface-e.g. in lieu of transmitting the information via a second interface which is available prior to the first interface becoming available.
