Abstract
A manner for judiciously snooping or otherwise monitoring bus operations associated with maintaining cache or other memory coherency in a computing system. A bus snoop information storage mode is established that identifies information pertaining to the bus snoop operations used to maintain memory coherency. The bus snoop information storage mode is selectable, relative to possible other modes. When the bus snoop information storage mode is activated, the information pertaining to the bus snoop operations occurring in connection with bus snoop stall cycles is disregarded, while the current state of the information pertaining to the bus snoop operations upon completion of the bus snoop operations is stored.
