Abstract:
A method and apparatus may provide for detecting a performance state transition in a processor core and bouncing a core snoop message on a shared interconnect ring in response to detecting the performance state transition. The core snoop message may be associated with the processor core, wherein a plurality of processor cores may be coupled to the shared interconnect ring via a distributed last level cache controller.
