Abstract
A power state broadcast mechanism. A master device may broadcast a message through the use of a protocol to each of one or more slave devices to inform the slave devices of the power state of a computer system. The broadcast message may include a protocol header indicating the start of the broadcast transaction, a function type parameter indicating the type of broadcast transaction, and power state data indicating the power state of the computer system. Each of the slave devices may read the protocol header to detect the start of a broadcast transaction, and the function type parameter to determine the type of broadcast transaction. If the function type parameter indicates a power state broadcast transaction, each of the slave devices may read the power state data included in the broadcast message and determine whether to adjust the current power state of the slave device.
