Abstract
Methods and apparatuses to control cache line coherency are described. A processor may include a first core having a cache to store a cache line, a second core to send a request for the cache line from the first core, moving logic to cause a move of the cache line between the first core and a memory and to update a tag directory of the move, and cache line coherency logic to create a chain home in the tag directory from the request to cause the cache line to be sent from the tag directory to the second core. A method to control cache line coherency may include creating a chain home in a tag directory from a request for a cache line in a first processor core from a second processor core to cause the cache line to be sent from the tag directory to the second processor core.
