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.
