How to open debug and trace for KNI

[Yasin CANER]

ubuntu 20.04.3 LTS
Kernel 5.4.0-110-generic
DPDK Version dpdk-stable-20.11.3
Intel e810-C
Driver ice-1.8.8.tar
ice_load_pkg_type(): Active package is: 1.3.28.0, ICE OS Default Package

Hello ,

I ve an enviroment as above.

I try to run DPDK app that is already can run i40e driver with Intel XL710 or X700 NIC but not on e810-C

When DPDK-app is on run , KNI is allocated but there is not any KNI interface on server. I try to open debug and trace logs so try to understand what is going on. So eal-> debug ,somehow, is activated but not for KNI? I need to understand why KNI is not working

Compile flags with meson

Step 1. meson -Denable_kmods=true -Dbuildtype=debug -Denable_trace_fp=true dpdk-stable-20.11.3
     2. ninja
     3. ninja install
     4. ldconfig
