Abstract
Particular embodiments described herein can offer a method that includes powering down a root port; initiating a first downstream cycle by a central processing unit (CPU) to the root port; identifying a power up activity for the CPU; and triggering an exit flow for a power state in conjunction with sending a second downstream cycle to the root port. In more particular embodiments, the triggering of the exit flow for the power state and the sending of the second downstream cycle to the root port occurs in a substantially parallel fashion. In addition, a prewake indicator can be sent to the root port to trigger the exit flow before the CPU is powered up and the second downstream cycle is sent.
