Hi, The continus burst of I/O Errors occured, as indicated below, when the helloworld application of dpdk2.2.0 example was running: EAL: Error reading from file descriptor 13: Input/output error EAL: Error reading from file descriptor 13: Input/output error EAL: Error reading from file descriptor 13: Input/output error EAL: Error reading from file descriptor 13: Input/output error
I installed the dpdk in virtual machine: centos7 + kvm. One NIC was bound to igb_uio mode. And if I unbound the NIC to e1000, then no error happened with helloworld running. I had tried updating the igb_uio.c according the following patch,but the error still existed. http://dpdk.org/dev/patchwork/patch/945/ Any suggestion is appreciated. Best regards, Guanghua
