[dpdk-users] DPDK-PKTGEN- Did not find any ports to use

[Vamsi Kommana]

Hi Team,

I was trying to install DPDK-Pktgen(Pktgen version 2.7.7 using
DPDK-1.7.1) for testing 10G Ethernet ports using NIC card, with 4
cores(1: Kernel 1:logs for pktgen 2:for Tx Rx of traffic).

But i was ending up with "*** Did not find any ports to use ***" while I was using the below mentioned command

Command:
--------
./app/build/pktgen -c 0x0c -n 3 --proc-type auto -m 512 --file-prefix pg
-- -T -P -m "2.0,3.1"
collected logs are as below...

On googling i found the issues might be due to binding and when i tried the below steps i was ending up with binding failed and logs are as below

[root@localhost tools]# ./dpdk_nic_bind.py --status

Hi,

Try with --bind or just -b (but not with -bind, i.e., not with a single dash).

See the usage:

   ./tools/dpdk_nic_bind.py --help

Hi John,

Thanks for the reply, sorted out the issue.
I was successfully able to run pktgen.

Thanks,

The performance may mean you have the NIC plugged into a PCIex4 slot and not a PCIex8 or the performance of the PCIe slot is not able to reach the performance of the NIC. I am just guessing here as Pktgen appears to be running and somewhat out of scope for debugging Pktgen issues.

Some NIC’s do not record the correct number of packets send or sent for some reason or another. Sorry you need to look at the data sheet for the NIC.

>2. Also, in case there are Rx errors, should these be interpreted as Buffer overruns ? How to debug such a case.

Yes, RX errors are handled by the NIC and you need to read the data sheet to understand how they handle RX errors.

>3. I believe, to run a test for a particular duration, we should be setting the packet counts to Tx ( set <portlist> count <value > ). Is this correct ? On setting this, I sometimes see, that Tx stops before the actual number of packets are sent out. On repeating this a couple of times, correct behavior is seen.

Using a Lua script is the best way to send for a specific time, have a look at the rfc2544.lua or the traffic-profile.lua script in Pktgen.

Also you need to make sure the PCIe bus is directly connected to the socket you are running Pktgen. In some systems the PCIe bus for the second socket is on a bridge, which can cause some problems in performance. The other issue is pktgen maybe going across the QPI bus between sockets and that is a huge performance hit.

Re: [dpdk-users] DPDK-PKTGEN- Did not find any ports to use

[Mudit Simlote]

Hello Keith,

Thanks for your reply !!

We have moved to Intel Sandy Bridge ( Intel Xeon ) with 24 logical cores ( with hyperthreading enabled )

I have picked up logical cores from the same CPU socket ( now, pktgen stats and others run on one of the cores, and 4 cores are used for Rx / Tx processing ), basically Rx and Tx separated out on a different logical cores per port.
With this configuration, I see for small packets ( 64 bytes ) best packet transmission we have reached thus far is close to 7.2 gbps ( less than 14.88 Mpps ).

How do I verify whether pktgen goes through a QPI bus between sockets ( as per my understanding, since all cores selected are from the same socket , this would not matter  ? )

Also, would like a couple of clarifications with the Rx and Tx counters ( like, sometimes Tx value lesser than Rx ).
1. As, I understand counters are read from the NIC , could there be a situation where the packet count ( to transmit ) is over, and the last batch of counter updation ignored etc.
2. Also, in case there are Rx errors, should these be interpreted as Buffer overruns ? How to debug such a case.
3. I believe, to run a test for a particular duration, we should be setting the packet counts to Tx ( set <portlist> count <value > ). Is this correct ? On setting this, I sometimes see, that Tx stops before the actual number of packets are sent out. On repeating this a couple of times, correct behavior is seen.

I will get back to you on the PCI setup ( whether our socket connects directly to the PCIe or not ).

Appreciate your help.

Thanks,
Mudit.

Hi All,

What is the system CPU’s you are using I did not find that listed, but I expect it is not the issue here.

The performance with one core should be fine as long as they are two different physical cores on the same socket. Also you need to make sure the PCIe bus is directly connected to the socket you are running Pktgen. In some systems the PCIe bus for the second socket is on a bridge, which can cause some problems in performance. The other issue is pktgen maybe going across the QPI bus between sockets and that is a huge performance hit.

Using the cpu_layout.py tool to verify you are using two different physical cores, then make sure they are on the socket connected to the PCIe bus.

BTW, the ‘-p 0x03’ option is no longer needed for Pktgen, I updated the docs a while back, but it seems to be used :-( this is not a problem for pktgen I just ignore the option.

The next thing is to loop back the cable from one port to the other on the Pktgen machine and make sure you can the performance at wire rate. Then you can debug the other machine.

Re: [dpdk-users] DPDK-PKTGEN- Did not find any ports to use

[Wiles, Keith]

Hi All,

What is the system CPU’s you are using I did not find that listed, but I expect it is not the issue here.

The performance with one core should be fine as long as they are two different physical cores on the same socket. Also you need to make sure the PCIe bus is directly connected to the socket you are running Pktgen. In some systems the PCIe bus for the second socket is on a bridge, which can cause some problems in performance. The other issue is pktgen maybe going across the QPI bus between sockets and that is a huge performance hit.

Using the cpu_layout.py tool to verify you are using two different physical cores, then make sure they are on the socket connected to the PCIe bus.

BTW, the ‘-p 0x03’ option is no longer needed for Pktgen, I updated the docs a while back, but it seems to be used :-( this is not a problem for pktgen I just ignore the option.

The next thing is to loop back the cable from one port to the other on the Pktgen machine and make sure you can the performance at wire rate. Then you can debug the other machine.

Re: [dpdk-users] DPDK-PKTGEN- Did not find any ports to use

Including Mudit...

Hi Keith,

Since I will be OOO if you need any information Mudit will assist you.

Thanks,

Subject: Re: [dpdk-users] DPDK-PKTGEN- Did not find any ports to use

Hi Keith,

Thanks for the reply...

I was able to resolve the issue after successfully binding the ports by giving the command "./dpdk_nic_bind.py -b igb_uio p1p2".

But we are facing issues about the performance numbers we are getting measured through the pktgen application provided by Wind River Systems.
We are having two machines, each equipped with 2 dual-port 10 GbE NICs (with a total of 4 ports). Machine 0 runs DPDK code, and Machine 1 runs Wind River System's DPDK-PKTGEN.
After successful installation we are trying to test the line rate with Pkt size 64 we are observing very poor line rate( less than 1G) and the statistics screen shot is attached to mail

Our test bed topology is as below
1. 2 NIC cards in two systems with DPDK running on one and DPDK-PKTGEN on another end connected back to back with cat6 Cables 2. Running on fedora-20 3. Having 3 logical cores, 1 for Display statistics, and remaining two are for Rx/Tx and the command we used to run pktgen is as mentioned bellow ./app/build/pktgen -c 0x0e -n 3 --proc-type auto --file-prefix pg -- -p 0x03 -P -m "2.0,3.1"

Does using only one logical cores per port for both Rx/Tx will effect the line rate ? even in this case i am transmitting traffic only from port 0 to port 1 using command "start 0" from pktgen in this case i am expecting minimum 5GBPS.

please let me know if i miss any steps.

Thanks in advance,
Kommana

It appears you did not add ports to the UIO module. The dpdk_nic_bind.py shows no ports attached to the UIO module, you need to use the dpdk_nic_bind.py to add them . Look at the setup.sh script and adjust it to help get the system setup, which only needs to be run once per reboot.

Re: [dpdk-users] DPDK-PKTGEN- Did not find any ports to use

[Vamsi Kommana]

Hi Keith,

Thanks for the reply...

I was able to resolve the issue after successfully binding the ports by giving the command "./dpdk_nic_bind.py -b igb_uio p1p2".

But we are facing issues about the performance numbers we are getting measured through the pktgen application provided by Wind River Systems.
We are having two machines, each equipped with 2 dual-port 10 GbE NICs (with a total of 4 ports). Machine 0 runs DPDK code, and Machine 1 runs Wind River System's DPDK-PKTGEN.
After successful installation we are trying to test the line rate with Pkt size 64 we are observing very poor line rate( less than 1G) and the statistics screen shot is attached to mail

Our test bed topology is as below
1. 2 NIC cards in two systems with DPDK running on one and DPDK-PKTGEN on another end connected back to back with cat6 Cables
2. Running on fedora-20
3. Having 3 logical cores, 1 for Display statistics, and remaining two are for Rx/Tx and the command we used to run pktgen is as mentioned bellow
./app/build/pktgen -c 0x0e -n 3 --proc-type auto --file-prefix pg -- -p 0x03 -P -m "2.0,3.1"

Does using only one logical cores per port for both Rx/Tx will effect the line rate ? even in this case i am transmitting traffic only from port 0 to port 1 using command "start 0" from pktgen in this case i am expecting minimum 5GBPS.

please let me know if i miss any steps.

Thanks in advance,
Kommana

It appears you did not add ports to the UIO module. The dpdk_nic_bind.py shows no ports attached to the UIO module, you need to use the dpdk_nic_bind.py to add them . Look at the setup.sh script and adjust it to help get the system setup, which only needs to be run once per reboot.
