Abstract: A method and apparatus for providing power state information using in-band signaling are described. In one embodiment, an integrated circuit (IC) device comprises a controller operable to receive a command from a platform control bus, the command requesting data that is unrelated to information about a power state in which the IC resides; and control logic operable to obtain data for inclusion in a response to the command, wherein the controller is operable to send the response over a bus, the response containing at least a portion of the data responsive to the command and containing power state information for the IC.
