Abstract

A method and apparatus for handling cache snoop errors. According to one method disclosed, a snoop cycle having a snoop address is generated by a first bus agent.

As a result of the detected snoop error, the snoop error is signaled to the first bus agent, the bus agent which generated the snoop cycle.
