DMND_RFO 1 (R/W). Counts the number of demand and DCU prefetch reads for
ownership (RFO) requests generated by a write to data cacheline.
Does not count L2 RFO.
DMND_IFETCH 2 (R/W). Counts the number of demand and DCU prefetch instruction
cacheline reads. Does not count L2 code read prefetches.
WB 3 (R/W). Counts the number of writeback (modified to exclusive)
transactions.
PF_DATA_RD 4 (R/W). Counts the number of data cacheline reads generated by L2
prefetchers.
PF_RFO 5 (R/W). Counts the number of RFO requests generated by L2
prefetchers.
PF_IFETCH 6 (R/W). Counts the number of code reads generated by L2
prefetchers.
OTHER 7 (R/W). Counts one of the following transaction types, including L3
invalidate, I/O, full or partial writes, WC or non-temporal stores,
CLFLUSH, Fences, lock, unlock, split lock.
UNCORE_HIT 8 (R/W). L3 Hit: local or remote home requests that hit L3 cache in the
uncore with no coherency actions required (snooping).
OTHER_CORE_HI
T_SNP
9 (R/W). L3 Hit: local or remote home requests that hit L3 cache in the
uncore and was serviced by another core with a cross core snoop
where no modified copies were found (clean).
OTHER_CORE_HI
TM
10 (R/W). L3 Hit: local or remote home requests that hit L3 cache in the
uncore and was serviced by another core with a cross core snoop
where modified copies were found (HITM).
Reserved 11 Reserved
REMOTE_CACHE_
FWD
12 (R/W). L3 Miss: local homed requests that missed the L3 cache and
was serviced by forwarded data following a cross package snoop
where no modified copies found. (Remote home requests are not
counted)
REMOTE_DRAM 13 (R/W). L3 Miss: remote home requests that missed the L3 cache and
were serviced by remote DRAM.
LOCAL_DRAM 14 (R/W). L3 Miss: local home requests that missed the L3 cache and
were serviced by local DRAM.
NON_DRAM 15 (R/W). Non-DRAM requests that were serviced by IOH.
