Performance monitor counters
If at least one event is captured in one of the interrupt indication registers, an active
PMON service request is directed towards the interrupt module.
by the time base event. The data accumulated during the previous time period
can be accessed by the indirect access scheme. The counters are cleared when
the time base expires. All counters are saturating, and will not overflow.
9.3.5 Block base 0x0A00 registers
LID associated event counters (Block_base
0x0A00 + Register_offset 0x000 to 0x17F)
interface and for each LID to or from a SPI-4 module. LID associated event
counters keep track of packets, packets not delineated by an SOP and an EOP,
or error-tagged packets.
9.3.6 Block base 0x0C00 registers
Non LID associated event counters (Block_base 0x0C00 + Register_offset 0x00
to 0x0B)
in the Offset column.

Offset
LID*6+0 SPI-3 ingress good packet counter
LID*6+1 SPI-3 ingress bad packet counter(error tagged)
LID*6+2 SPI-4 ingress good packet counter
LID*6+3 SPI-4 ingress bad packet counter(abort)
LID*6+4 SPI-3 egress packet counter
LID*6+5 SPI-4 egress packet counter
Offset
Two categories of events are captured: LID and non LID associated events.
All events and diagnostics data are accumulated during an interval defined
A set of event counters is provided for each of the 64 LIDs on each SPI-3
Non LID Associated Event Counters are associated with SPI-3 and SPI-4 physical interfaces. The register offset is shown
