Abstract
Methods and apparatus relating to improving the value of F-state by increasing a local caching agent's data forwarding are described. In one embodiment, the opportunity for forwarding from a local caching agent is improved by allowing the local caching agent to keep an F-state copy of the line while sending an S-state copy to the requestor (e.g., in response to a non-ownership read operation). Other embodiments are also disclosed.
