Partial way hint line replacement algorithm for a snoop filter

摘要

In an embodiment, a method is provided. The method of this embodiment provides receiving a request for data from a processor of a plurality of processors, determining a cache entry location based, at least in part, on the request, storing the data in a cache corresponding to the processor at the cache entry location, and storing a coherency record corresponding to the data in a snoop filter in accordance with one of the following, if there is a cache miss: at the cache entry location of a corresponding affinity in the snoop filter if the cache entry location is found in the corresponding affinity, or at a derived cache entry location of the corresponding affinity if the cache entry location is not found in the corresponding affinity.
