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. A second bus agent detects a snoop error in response to that bus cycle. 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.
