NULL	LLC_HIT.ANY_RESPONSE	0x3f803c	0,1	hit in the LLC
NULL	LLC_HIT.NO_SNOOP_NEEDED	0x01003c	0,1	hit in the LLC and sibling core snoops are not needed as either the core-valid bit is not set or the shared line is present in multiple cores
NULL	LLC_HIT.SNOOP_MISS	0x02003c	0,1	hit in the LLC and the snoops sent to sibling cores return clean response
NULL	LLC_HIT.HIT_OTHER_CORE_NO_FWD	0x04003c	0,1	hit in the LLC and the snoops to sibling cores hit in either E/S state and the line is not forwarded
NULL	LLC_HIT.HITM_OTHER_CORE	0x10003c	0,1	hit in the LLC and the snoop to one of the sibling cores hits the line in M state and the line is forwarded
