摘要： Disclosed are embodiments of a method, apparatus and system for a low power state for a point-to-point link. During the low power state, the signal on both conductors of a differential transmit pair are driven to electrical idle. Analog activity detectors are enabled during the low power state and are disabled during normal power state. Exit from the low power state does not require a physical layer re-initialization sequence. Other embodiments are also described and claimed.

摘要： A method for effecting an in-band reset of the physical layers of two agents interconnected through a link-based interconnection scheme. In accordance with one embodiment of the invention, a first of the two agents ceases its forwarded clock to initiate the in-band reset. Upon realization of the cessation, a second agent ceases its forwarded clock and proceeds to a reset state. The first agent then proceeds to a reset state. Subsequently, after waiting a specified period of time, both agents proceed with a re-initialization of the physical layer. In accordance with one embodiment of the invention, the re-initialization of the physical layer is effected without impacting other layers of the interconnection hierarchy.
