ABSTRACT:
Methods and apparatus to manage communication bus power states are described. In one embodiment, an apparatus comprises a bus including a master node and at least a first slave node, logic to transmit a first power state change request from the master node to the first slave node, logic to receive the first power state change request in the first slave node, and logic to designate the first slave node as the master node when the first slave node denies the first power state change request.
