Abstract
To address the need for power management, the following facilitates maintaining power states in an efficient manner based at least in part on managing packets at different layers of an input/output interface that supports multiple layers. One specific example prevents a destructive event for link layer control logic because packets and information might have been lost or dropped due to a hang condition and/or a dropped packet. In yet another example of power management, this facilitates a low power platform state by preventing the loss of packets or data upon exiting a platform power state upon initiation of a link reset condition by preventing certain types of packets from reaching link layer controller logic.
