Subject: [dpdk-users] EAL : Input/output error on DPDK 2.2.0
Date: Wed, 17 Feb 2016 09:49:29 +0000 [thread overview]
Message-ID: <PS1PR0601MB1370BE25940976BB5717F4C6BBAE0@PS1PR0601MB1370.apcprd06.prod.outlook.com> (raw)
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
