[dpdk-users] Getting started with dpdk

[dpdk-users] Getting started with dpdk

[Rahul Kishen]

Hi Team,
My colleague and I have been assigned a project on dpdk. We have basic
knowledge of linux and networking. We tried to install dpdk on an IBM
server with an Intel x86_64 processor (on Ubuntu 14.04) and the hello world
program ran without any problems.

The basic forwarding program however, is giving us trouble and it throws an
error saying:
The number of ports are not even.
Both the ethernet ports are bound using devbind.py.

Also, both of us have just started out with this project and we don't have
a frame of reference as to where to start. It would be of great help to us
if someone could help us in getting started and we are trying to get our
project moving. We would like to know where to read from and the
prerequisites required to deeply understand what happens in dpdk.
Thanking you in advance.

Regards,
Rahul Kishen D

Have you gone through: http://dpdk.org/doc/guides/linux_gsg/index.html ?
Or http://dpdk.org/doc as a start point.
This is elaborate enough to get you started with examples.

If you are facing issue, I suggest putting complete output/error log in mail.
And, for "The number of ports are not even.", first place to check would be your port mask.

Hi, Rahul,

What does "devbind.py -s" show ? and what is the command line you are using for running the forwarding app?

Rami Rosen

Hi Rahul,

Refer this link "http://dpdk.org/doc/guides/sample_app_ug/skeleton.html"
for understanding the basic
forwarding program. You should also pass the valid command line parameters
to make this run successfully.
All the info are available in the above link.

Thanks,
Mohanraj V
