Abstract
A method from managing power state transitions in a computing system is disclosed. A processor may initiate a change in power state from a first initial power state to a first new power state and, in response to initiating the change, send an initial notification to a system integrated circuit using a first communication channel, and deactivate the first communication based on responses to the initial notification. The processor may enter the first new power state in response to the deactivation of the first communication channel, and send a final notification to a management controller using a second communication channel. The management controller may send a message to the system integrated circuit upon receiving the final notification. The system integrated circuit may then transition from a second initial power state to a second new power state based on the message.
