Device and method for efficient transitioning to and from reduced power state

A method for performing power state transitioning in a processing device comprising a plurality of components, the method comprising:

• receiving, by a power management controller, an indication that the plurality of components are idle;
• executing, by the power management controller, a process to enter a component into a reduced power state in response to receiving an acknowledgement from the component of a request from the power management controller to remove power to the component;
• and
• executing, by the power management controller, a process to exit the component from the reduced power state in response to the component being active.

A non-transitory computer-readable medium comprising instructions that, when executed by a processing device comprising a plurality of components, cause the processing device to perform operations for performing power state transitioning, the operations comprising:

• receiving an indication that the plurality of components are idle;
• executing a process to enter a component into a reduced power state in response to receiving an acknowledgement from the component of a request to remove power to the component;
• and
• executing a process to exit the component from the reduced power state in response to the component being active.
