Intel Xeon E5-2600 Series - Cn_Msr_Pmon_Box_Filter Register - Field Definitions

Reference Number: 327043-001 29
Intel® Xeon® Processor E5-2600 Product Family Uncore Performance Monitoring
Note: Not all transactions can be associated with a specific thread. For example, when a
snoop triggers a WB, it does not have an associated thread. Transactions that are
associated with PCIe will come from “0x1E” (b11110).
Note: Only one of these filtering criteria may be applied at a time.
Refer to Table 2-144, “Opcodes (Alphabetical Listing)” for definitions of the opcodes found in the
following table.

opc
(7b IDI Opcode?
w/top 2b 0x3)
31:23 RW 0 Match on Opcode (see
Table 2-13, “Opcode Match by
IDI Packet Type for
Cn_MSR_PMON_BOX_FILTER.opc”)
NOTE: Only tracks opcodes that come from the IRQ. It is not
possible to track snoops (from IPQ) or other transactions from
the ISMQ.
state 22:18 RW 0 Select state to monitor for LLC_LOOKUP event. Setting multiple
bits in this field will allow a user to track multiple states.
b1xxxx - ‘F’ state.
bx1xxx - ‘M’ state
bxx1xx - ‘E’ state.
bxxx1x - ‘S’ state.
bxxxx1 - ‘I’ state.
nid 17:10 0 0 Match on Target NodeID.
NID is a mask filter with each bit representing a different Node in
the system. 0x01 would filter on NID 0, 0x2 would filter on NID
1, etc
rsv 9:8 RV 0 Reserved (?)
rsv 7:5 RV 0 Reserved (?)
tid 4:0 0 0 [3:1] Core-ID
[0] Thread 1/0
When .tid_en is 0; the specified counter will count ALL events
Thread-ID 0xF is reserved for non-associated requests such as: -
LLC victims - PMSeq - External Snoops
