Average latency of read request – from
initialization until end of completions.
Estimated latency is ~5 s
Average latency of read request RTT–
from initialization until the first
completion is arrived (round trip time).
Estimated latency is 1 s
Requests that reached time out.
Completion latency above threshold
Completion Latency above Threshold –
for RTT
Dwords of the packet transmitted
(transferred to the physical layer),
include payload and header.
Dwords of packet received (transferred
to the physical layer), include payload
and header.
All types of DLLP packets transmitted
from link layer.
Flow control DLLP transmitted from link
layer.
Ack DLLP transmitted.
All types of DLLP packets received.

Software selects the client that needs to be tested.
The statistic counter counts the number of read
requests of the required client.
In addition, the accumulated time of all requests are
saved in a time accumulator.
The average time for read request is:
[Accumulated time/number of read requests].
(Event 41 is for the counter).
Software selects the client that needs to be tested.
The statistic counter counts the number of read
requests of the required client.
In addition, the accumulated time of all RTT are
saved in a time accumulator.
The average time for read request is:
[Accumulated time/number of read requests].
(Event 43 is for the counter).
Number of requests that reached time out.
Software selects the client that needs to be tested.
Software programs the required threshold (in
GSCL_4 – units of 96 ns).
One statistic counter counts the time from the
beginning of the request until end of completions.
The other counter counts the number of events.
If the time is above threshold – add 1 to the event
counter.
(Event 46 is for the counter).
Software selects the client that needs to be tested.
Software programs the required threshold (in
GSCL_4 – units of 96 ns).
One statistic counter counts the time from the
beginning of the request until first completion arrival.
The other counter counts the number of events.
If the time is above threshold – add 1 to the event
counter.
(Event 48 is for the counter).
Include DLLP (Link layer packets) and TLP
(transaction layer packets transmitted.
Each 125 MHz cycle the counter increases by 1 (1
Dword) or 2 (2 Dwords).
Include DLLP (Link layer packets) and TLP
(transaction layer packets transmitted.
Each 125 MHz cycle the counter increases by 1 (1
Dword) or 2 (2 Dwords).
Each cycle, the counter increases by 1, if DLLP packet
was transmitted.
Each cycle, the counter increases by 1, if message
was transmitted
Each cycle, the counter increases by 1, if message
was transmitted.
Each cycle, the counter increases by 1, if DLLP was
received.
