"no valid ports" while building app in dpdk. #89

Closed harminds closed 5 years ago

harminds commented 5 years ago

Building an application using dpdk-v18.02 and getting an error as "no valid ports". I tried dpdk-v19.02 and it's giving the same error. This is the error: EAL: Detected 40 lcore(s) EAL: Multi-process socket /var/run/.rte_unix EAL: Probing VFIO support... EAL: PCI device 0000:04:00.0 on NUMA socket 0 EAL: probe driver: 10ee:9038 xnic EAL: Requested device 0000:04:00.0 cannot be used EAL: Error - exiting with code: 1 Cause: Error: no valid ports

The port is already bound to the driver: dpdk/usertools/# python dpdk-devbind.py --bind=igb_uio 04:00.0 0000:04:00.0 already bound to driver igb_uio, skipping
