[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。
