| H A D | packet.hh | 4902:bc666118c6e2 Sat Jul 21 16:45:00 EDT 2007 Steve Reinhardt <stever@eecs.umich.edu> Several more fixes for multi-level timing coherence. - Add "deferred snoop" flag to Packet so upper-level caches can distinguish whether lower-level cache request was in-service or not at the time of the original snoop. - Revamp response handling to properly handle deferred snoops on non-cache-fill requests (i.e. upgrades). - Make sure forwarded writebacks are kept in write buffer at lower-level caches so they get snooped properly. |
