mem, config: Selective use of snoop filter
Disable the default snoop filter in the SystemXBar so that the typical membus does not have a snoop filter by default. Instead, add the snoop filter only when there are caches added to the system (with the caches / l2cache options). The underlying problem is that the snoop filter grows without bounds (for now) if there are no caches to tell it that lines have been evicted. This causes slow regression runs for all the atomic regressions. This patch fixes this behaviour. --HG-- extra : source : f97c20511828209757440839ed48d741d02d428f
