Abstract: Providing multi-socket memory coherency using cross-socket snoop filtering in processor-based systems is disclosed. In this regard, a processor-based system provides a plurality of processor sockets, each associated with a coherency directory including a plurality of coherency directory entries each storing status indicators corresponding to memory granules of a local memory hierarchy. A point of serialization (POS) circuit of the processor-based system receives a memory access request including a local memory address, and retrieves a coherency directory entry corresponding to the local memory address. If a status indicator of the coherency directory entry corresponding to a memory granule associated with the local memory address indicates that a remote snoop is required, the POS circuit performs the remote snoop of one or more remote processor sockets indicated by the status indicator. If not, the POS circuit returns data from the local memory hierarchy for the memory access request.
