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.
