centos 安装 dpdk17.11.1 版本

[root@localhost kmod]# cat /etc/redhat-release

CentOS Linux release 7.4.1708 (Core)

[root@localhost kmod]# uname -r

3.10.0-693.el7.x86_64

DPDK 版本 dpdk-stable-17.11.1

编译正常 OK

modprobe uio

insmod igb_uio.ko 的时候提示

[root@localhost kmod]# insmod igb_uio.ko

insmod: ERROR: could not insert module igb_uio.ko: Unknown symbol in module

网上查看了下，查看 dmesg

[root@localhost kmod]# dmesg |tail

查找__x86_indirect_thunk_rax 是一个补丁用到的，retpoline 方案。

然后找不到更多的资料了，这问题咋整，知道的教一下，谢谢大神么。
