UNC_GQ_CYCLES_FULL.READ_
TRACKER
Uncore cycles Global Queue read tracker is full.

UNC_GQ_CYCLES_FULL.WRITE
_TRACKER
Uncore cycles Global Queue write tracker is full.
00H

UNC_GQ_CYCLES_FULL.PEER_
PROBE_TRACKER
Uncore cycles Global Queue peer probe tracker is full.
The peer probe tracker queue tracks snoops from the
IOH and remote sockets.

UNC_GQ_CYCLES_NOT_EMPTY
.PEER_PROBE_TRACKER
Uncore cycles were Global Queue peer probe tracker
has at least one valid entry. The peer probe tracker
queue tracks IOH and remote socket snoops.
02H
01H
UNC_GQ_OCCUPANCY.READ_T
RACKER
Increments the number of queue entries (code read,
data read, and RFOs) in the tread tracker. The GQ read
tracker allocate to deallocate occupancy count is
divided by the count to obtain the average read tracker
latency.
03H
01H
UNC_GQ_ALLOC.READ_TRACK
ER
Counts the number of tread tracker allocate to
deallocate entries. The GQ read tracker allocate to
deallocate occupancy count is divided by the count to
obtain the average read tracker latency.
