For now we refrain from globally adding a snoop filter to the SystemXBar, since the latter is also used in systems without caches. In scenarios without caches the snoop filter will not see any writeback/clean evicts from the CPU ports, despite the fact that they are snooping. To avoid inadvertent use of the snoop filter in these cases we leave it out for now. A size check is added to the snoop filter, merely to ensure it does not grow beyond the total capacity of the caches above it. The size has to be set manually, and a value of 8 MByte is choosen as suitably high default. |
