Abstract
A coherence protocol message is sent corresponding to a particular cache line. A potential conflict involving the particular cache line is identified and a forward request is sent to a home agent to identify the potential conflict. A forward response can be received in response to the forward request from the home agent and a response to the conflict can be determined.
