LS2085ARDB and OpenDataPlane

nicolaskury — Mon, 11 Jan 2016 13:04:01 GMT

I have received a LS2085ARDB board and I would like to try OpenDataPlane. I start with the default (pre-installed) image and it seems that OpenDataPlane is already installed. In usr/nadk/nadk-static/bin there are some applications such odp_pktio and odp_l2fwd.

But I have some errors

root@ls2085ardb:/usr/nadk/nadk-static/bin# ./odp_generator

odp_init.c:211:odp_nadk_init_global():Enviroment varialble DPRC_NAME is not setodp_init.c:271:odp_init_global():ODP nadk init failed.

odp_generator.c:573:main():Error: ODP global init failed.

odp_init.c:124:odp_finish():odp_finish

Should I also run the script ./usr/nadk/nadk-static/bin/bind_dprc.sh ?

I didn't find the documentation. My ethernet interface in front the board are also not available in Linux, is it normal ?

Thank you!

Ok, I have progressed but I have still some problems...

First;

cd /usr/nadk/nadk-static/bin
./dynamic_dpl.sh dpmac.1 dpmac.2

####### Parsing argument number 1 (dpmac.1) #######
dpni.0 created with MAC addr = 00:00:00:00:00:01
Disconnecting the dpmac.1
dpmac.1 Linked with dpni.0
dpni.0 assigned to dprc.2
dpmac.1 <--------connected------> dpni.0
******* End of parsing ARGS *******
[...]
dpmac.2 <--------connected------> dpni.5
USE dprc.2 FOR YOUR APPLICATIONS

So I export DPRC_NAME:

export DPRC_NAME='dprc.2'

Then

./odp_l2fwd -i dpni-0,dpni-5 -m 0

I'm not sure what the format of the interface is. dpni-0 or dpni.0 ?

And what is the relation between dpmac, dpni and the port in front the board ? Is dpmac.1 the eth1 port ?

The board doesn't forward anything... What did I miss ? I'm sending packet to dst mac 00:00:00:00:00:01 (dpmac.1 <-> dpni.0)

The log

Hello nicolaskury,

On LS2085ARDB, dpmac.1-dpmac.4 map XFI1-XFI4(SFPJ2-SFPJ6), dpmac.5 is XFI5(RJ45LAN1) and dpmac.7 is XFI7(RJ45LAN3), the connection between DPNI and DPMAC is defined by restool or in the DPL file.

Please check whether your target board is pre-loaded with the DPL file which allocates "dprc.1" with the following command, because in script dynamic_dpl.sh, a child resource container is created dynamically for NADK based on the parent resource container "dprc.1".

$restool dprc list

In addition, it's better to use the latest EAR5.0 images with ODP API version: 1.1.

I checked your log, it looks there is no obvious error, I attached my log file for running odp_l2fwd with pre-loaded DPL file dpl-eth-aiop-nadk.0x2A_0x41, please have a reference.

$ restool dprc list

$ cd /usr/nadk/nadk-static/bin/

$ source ./dynamic_dpl.sh dpmac.3 dpmac.4

$ export DPRC=dprc.2

$ ./odp_l2fwd -c 2 -m 0 -i dpni-0,dpni-2

===== Spirent =====

Interface 1:

Destination MAC address 00:00:00:00:00:01

Source MAC address 00:10:94:00:00:02

Interface 2:

Destination MAC address 00:00:00:00:00:02

Source MAC address 00:10:94:00:00:03

If your problem remains, please attach your u-boot , kernel and the application setup logs.

Have a great day,
Yiping

Thank you for your answer.

Could you look at my picture please ? I'm not sure to understand the the mapping between dpmac and the physical interfaces. I used dpni-0 and dpni-5 because first, I would like to try with a RJ45 cable.

./odp_l2fwd -c 2 -m 0 -i dpni-0,dpni-5

Where can I get the latest EAR5.0 images with ODP API version: 1.1 ? Could you send me all necessary files in order to executes some tests on ODP ? It is for a project at my university, I only need to run some tests on ODP, no more... It would be a gain of time.

I have attached the full log. I loaded the pre-installed image, I don't know if dpl-eth-aiop-nadk.0x2A_0x41 is also loaded...

I noticed these errors during the boot of uboot. Are they important ?

Then I sent traffic to 00:00:00:00:00:01. But it seems not forwarding.

Thank you

Hello nicolaskury,

I checked your picture and the console log.

On the target board dpmac.5 is ETH0 and dpmac.7 is ETH2, please change to use the correct networking interfaces and check whether there would be any progress.

Please refer to the following from Linux SDK document.

Have a great day,
Yiping

Re: LS2085ARDB and OpenDataPlane

nicolaskury — Mon, 18 Jan 2016 11:17:49 GMT

Thanks for your prompt reply.

It seems working ! It was really a dummy issue! The LS2085 was connected to a HP switch and the ports in the switch stayed down (no idea why). When I connect the board directly to a computer that generates traffic, it works.

Now I know that ODP works and what is the relation between dpmac and the physical ports, I'm going to test the througput at 10Gb/s with a Spirent equipment.

Thank you for everything. I let you know if I succeed in doing the measures.

PS: are the performances (odp_l2fwd) better with ODP v1.1 ?
.

Re: LS2085ARDB and OpenDataPlane

yipingwang — Mon, 18 Jan 2016 11:29:51 GMT

Hello nicolaskury,

ODP v1.1 is included in Linux SDK EAR 5.0 release(the latest release for LS2085A), it would be better than the previous release, you could require the software ISOs from you local FAE or submit a service request.

Have a great day,
Yiping

Re: LS2085ARDB and OpenDataPlane

nicolaskury — Mon, 18 Jan 2016 13:01:01 GMT

I measured the throughput at 10Gb/s and the result is unfortunelly bad. I got only 1.39Mpps insteadof 14.48Mpps with packets size 64 Bytes. (with SFP as fibber and as copper)

./odp_l2fwd -c 2 -m 0 -i dpni-0,dpni-5

I don't have any local FAE. I'm a student, my school has received the LS2085 for my project. I could ask my teacher (responsabel) to request the SDK 5.0 but it may take time. Would it be not possible to get it from you ? Or to get an image with ODP 1.1 ? I just need to run odp_l2fwd, eventually odp_ipsec and see if the throughput is near to the maximal (14.48Mpps)

Thank you!

Hello nicolaskury,

Please use "-c" parameter to specify more cores(or threads) to run this application.

I will send EAR 5.0 image to you, please try whether it could run on your target board directly.

If your require the entire ISO, please refer to How I could create a Service Request? to submit a service request.

Have a great day,
Yiping

Hi!

Thank you for your help! I downloaded and booted on kernel-ls2085ardb.itb.

But I have an issue. The driver mc_restool (Management Complex restool) is not loaded so restool cannot work proprely. I have attached the full log.

root@ls2085ardb:/# restool -v
Freescale MC restool tool version 1.1
root@ls2085ardb:/# restool -m
open() failed for /dev/mc_restool: No such file or directory

And then I run dynamic_dpl.sh, there is the same error message.

root@ls2085ardb:/usr/nadk/nadk-static/bin# source ./dynamic_dpl.sh dpmac.5 dpmac.7
Available DPRCs

open() failed for /dev/mc_restool: No such file or directory
Created
####### Parsing argument number 1 (dpmac.5) #######
open() failed for /dev/mc_restool: No such file or directory

Unfortually, I haven't find any information about how to load this driver. How can I fixe the problem ?

The filed in red are not present in your image...

I had also tried to boot with dpl-eth-aiop-nadk.0x2A_0x41.dtb but I'm not sure if it correct... because it doesn't boot
