Subject: [dpdk-dev] APP outside the development kit issues
Date: Mon, 11 Oct 2021 10:54:10 +0200	[thread overview]
Message-ID: <CAFggs4NogSwZwottdkkCzD-o+do-NZDNQcaE724kheHjkLM04w@mail.gmail.com> (raw)

Hi,
I'm trying to create new examples for DPDK, more precisely for
bbdev but I'm facing different issues.
First, following this link (58. Building Your Own Application — Data Plane
Development Kit 21.11.0-rc0 documentation (dpdk.org)
<https://doc.dpdk.org/guides/prog_guide/build_app.html>), I found the
example for bbdev not working
with the following error message: "EAL: Error - exiting with code: 1
  Cause: cannot use port with ID 0!"

After digging a little bit, it seems that --vdev option is not creating the
device so I tried
to create it as proposed here (16. Wireless Baseband Device Library — Data
Plane Development Kit 21.11.0-rc0 documentation (dpdk.org)
<https://doc.dpdk.org/guides/prog_guide/bbdev.html>) but even if I include
"rte_bus_vdev.h" which
I think is where all the creation and initialization functions are defined,
I'm getting
an "undefined reference to rte_vdev_init"

Is there any flow diagram or something similar to understand how DPDK is
configuring the
devices? which example should I use as a reference to create my own
"outside of the kit"
examples?

Thanks in advance,
Ginés.
