The error message “Unknown symbol in module” typically indicates that there is a mismatch between the version of the kernel you are running and the version of the module you are trying to load.
To resolve this issue, you can try the following steps:
Ensure that you have built the DPDK libraries and drivers using the correct version of your kernel headers. Make sure you have followed the installation instructions provided by DPDK for your specific operating system.
Verify if you have loaded any conflicting modules or drivers that may cause conflicts with ‘igb_uio’. You can check currently loaded modules using
lsmodcommand:lsmod | grep igb
If any related modules appear, unload them using rmmod command:
sudo rmmod <module_name>
Rebuild and reinstall the DPDK ‘igb_uio’ module using the correct version of kernel headers.
If none of these solutions work, try updating your kernel or installing any required patches to ensure compatibility with DPDK.
If you continue to encounter issues, it may be helpful to seek assistance from DPDK community forums or mailing lists as they would have more specific knowledge about troubleshooting such errors in the context of DPDK usage.
