Abstract
Machine-readable media, methods, and apparatus are described for processing coherent requests of a computing device comprising multiple cache nodes. In some embodiments, a coherent switch may receive from a requesting cache node a coherent request for a line of memory. The coherent switch may further issue snoop requests to one or more non-requesting cache nodes based upon whether a snoop filter bypass mode is enabled. In particular, the coherent switch when not in snoop filter bypass mode may obtain coherency data from a snoop filter and may issue snoop requests to zero or more non-requesting cache nodes based upon the coherency data obtained from the snoop filter. Further, the coherent switch when in snoop filter bypass mode may bypass the snoop filter and may issue snoop requests to all non-requesting cache agents.
