28H
20H
UNC_QMC_ISOC_FULL.WRITE.C
H2
Counts cycles all the entries in the DRAM channel 2
high priority queue are occupied with isochronous
write requests.
29H
01H
UNC_QMC_BUSY.READ.CH0
Counts cycles where Quickpath Memory Controller has
at least 1 outstanding read request to DRAM channel
0.
29H
02H
UNC_QMC_BUSY.READ.CH1
Counts cycles where Quickpath Memory Controller has
at least 1 outstanding read request to DRAM channel
1.
29H
04H
UNC_QMC_BUSY.READ.CH2
Counts cycles where Quickpath Memory Controller has
at least 1 outstanding read request to DRAM channel
2.
29H
08H
UNC_QMC_BUSY.WRITE.CH0
Counts cycles where Quickpath Memory Controller has
at least 1 outstanding write request to DRAM channel
0.
29H
10H
UNC_QMC_BUSY.WRITE.CH1
Counts cycles where Quickpath Memory Controller has
at least 1 outstanding write request to DRAM channel
1.
29H
20H
UNC_QMC_BUSY.WRITE.CH2
Counts cycles where Quickpath Memory Controller has
at least 1 outstanding write request to DRAM channel
2.
2AH
01H
UNC_QMC_OCCUPANCY.CH0
IMC channel 0 normal read request occupancy.
2AH
02H
UNC_QMC_OCCUPANCY.CH1
IMC channel 1 normal read request occupancy.
2AH
04H
UNC_QMC_OCCUPANCY.CH2
IMC channel 2 normal read request occupancy.
2AH
07H
UNC_QMC_OCCUPANCY.ANY
Normal read request occupancy for any channel.
2BH
01H
UNC_QMC_ISSOC_OCCUPANCY.
CH0
IMC channel 0 issoc read request occupancy.
2BH
02H
UNC_QMC_ISSOC_OCCUPANCY.
CH1
IMC channel 1 issoc read request occupancy.
2BH
04H
UNC_QMC_ISSOC_OCCUPANCY.
CH2
IMC channel 2 issoc read request occupancy.
2BH
07H
UNC_QMC_ISSOC_READS.ANY IMC issoc read request occupancy.
2CH
01H
UNC_QMC_NORMAL_READS.C
H0
Counts the number of Quickpath Memory Controller
channel 0 medium and low priority read requests. The
QMC channel 0 normal read occupancy divided by this
count provides the average QMC channel 0 read
latency.
2CH
02H
UNC_QMC_NORMAL_READS.C
H1
Counts the number of Quickpath Memory Controller
channel 1 medium and low priority read requests. The
QMC channel 1 normal read occupancy divided by this
count provides the average QMC channel 1 read
latency.
2CH
04H
UNC_QMC_NORMAL_READS.C
H2
Counts the number of Quickpath Memory Controller
channel 2 medium and low priority read requests. The
QMC channel 2 normal read occupancy divided by this
count provides the average QMC channel 2 read
latency.
