Abstract

A method and apparatus to reduce the idle link power in a platform. In one embodiment of the invention, the host and its coupled endpoint(s) in the platform each has a low power idle link state that allows disabling of the high speed link circuitry in both the host and its coupled endpoint(s). This allows the platform to reduce its idle power as both the host and its coupled endpoint(s) are able to turn off their high speed link circuitry in one embodiment of the invention.
