• Definition:
Counts the number of cycles that the AD ring is being used at this ring stop. This
includes when packets are passing by and when packets are being sunk, but does not include when
packets are being sent from the ring stop. We really have two rings in JKT -- a clockwise ring and a
counter-clockwise ring. On the left side of the ring, the "UP" direction is on the clockwise ring and
"DN" is on the counter-clockwise ring. On the right side of the ring, this is reversed. The first half
of the CBos are on the left side of the ring, and the 2nd half are on the right side of the ring. In
other words (for example), in a 4c part, Cbo 0 UP AD is NOT the same ring as CBo 2 UP AD because
they are on opposite sides of the ring.

Victimized Lines that Match NID:
The NID is programmed in
Cn_MSR_PMON_BOX_FILTER.nid. In conjunction with
STATE = I, it is possible to monitor misses to specific
NIDs in the system.

Description
RSPI_WAS_FSE
bxxxxxxx1
Silent Snoop Eviction:
Counts the number of times when a Snoop hit in FSE states and
triggered a silent eviction. This is useful because this information is
lost in the PRE encodings.
WC_ALIASING
bxxxxxx1x
Write Combining Aliasing:
Counts the number of times that a USWC write (WCIL(F)) transaction
hit in the LLC in M state, triggering a WBMtoI followed by the USWC
write. This occurs when there is WC aliasing.

RFO_HIT_S
bxxxx1xxx
RFO HitS:
Number of times that an RFO hit in S state. This is useful for
determining if it might be good for a workload to use RspIWB instead
of RspSWB.
