Intel Xeon E5-2600 Series - Cbo Performance Monitor Event List

Intel® Xeon® Processor E5-2600 Product Family Uncore Performance Monitoring
34 Reference Number: 327043-001
Note: LLC_MPI only makes sense when measured either in the processor or at the system
level. There is no correlation between a specific CBo andthe instructions retired in a
specific core. Therefore it is necessary to add the LLC_LOOKUP term across all CBos
and divide by either all instructions retired in a core or all instructions retired across all
cores.
2.3.7 CBo Performance Monitor Event List
The section enumerates the performance monitoring events for the CBO Box.
CLOCKTICKS
• Title: Uncore Clocks
• Category: UCLK Events
• Event Code: 0x00
• Max. Inc/Cyc: 1, Register Restrictions: 0-3
• Definition:
COUNTER0_OCCUPANCY
• Title: Counter 0 Occupancy
• Category: OCCUPANCY Events
• Event Code: 0x1F
• Max. Inc/Cyc: 20, Register Restrictions: 1-3
• Definition: Since occupancy counts can only be captured in the Cbo's 0 counter, this event allows a
user to capture occupancy related information by filtering the Cb0 occupancy count captured in
Counter 0. The filtering available is found in the control register - threshold, invert and edge
detect. E.g. setting threshold to 1 can effectively monitor how many cycles the monitored queue
has an entry.
PCIE_DATA_BYTES:
Data from PCIe in Number of Bytes
(TOR_INSERTS.OPCODE

RING_THRU_DNEVEN_BYTES:
Ring throughput in the Down direction,
Even polarity in Bytes
RING_BL_USED.DN_EVEN * 32
RING_THRU_DNODD_BYTES:

RING_THRU_UPODD_BYTES:
Ring throughput in the Up direction, Odd
polarity in Bytes
RING_BL_USED.UP_ODD * 32
