DPDK目标没有IGO内核模块

Question

DPDK部署脚本执行时出现报错如下
ERROR: Target does not have the DPDK UIO Kernel Module.
To fix, please try to rebuild target.
如何拯救？

Answer 1

检查一下你的系统内核版本，看看是不是你的kernel内核版本太低，或升级一下你的内核。
下面是github上的readme。

README for setting up Pktgen with DPDK on Ubuntu 10.04 to 13.10 desktop, it should work on most Linux systems as long as the kernel has hugeTLB page support.

*** Note: Tested with Ubuntu 13.10 and up to 14.04 kernel version Linux 3.5.0-25-generic #39-Ubuntu SMP Mon Feb 25 18:26:58 UTC 2013 x86_64

I am using Ubuntu 13.10 x86_64 (64 bit support) for running pktgen/DPDK on a Westmere Dual socket board running at 2.4GHz with 12GB of ram 6GB per socket. The current kernel version is 3.5.0-25 (as of 2013-03-18) support, but should work on just about any new Linux kernel version.

To get hugeTLB page support your Linux kernel must be at least 2.6.33 and in the DPDK documents it talks about how you can upgrade your Linux kernel.

Here is another document on how to upgrade your Linux kernel. Ubuntu 10.04 is 2.6.32 by default so upgraded to kernel 2.6.34 using this HOWTO: http://usablesoftware.wordpress.com/2010/05/26/switch-to-a-newer-kernel-in-ubuntu-10-04/
