Hi Lu,

I do see the module there, but seems it is built against incorrect kernel
version and thus it is not loading:

# insmod ./dpdk/kmod/igb_uio.ko
insmod: ERROR: could not insert module ./dpdk/kmod/igb_uio.ko: Invalid
module format


dmesg:

[54394.611703] igb_uio: version magic '4.2.3-300.fc23.x86_64 SMP mod_unload
' should be '4.4.6-300.fc23.x86_64 SMP mod_unload '

uname -a:

# uname -a
Linux kube-node1 4.4.6-300.fc23.x86_64 #1 SMP Wed Mar 16 22:10:37 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux


I removed that kernel source and rebuild it - now it is loading and I am
able to find the device to igb_uio and
do see /dev/uio0 created.

I do see the device in dpdk now.

Thanks much.

Ferruh,

On my fedora23, I don't have igb_uio

# modprobe igb_uio
modprobe: FATAL: Module igb_uio not found in directory
/lib/modules/4.4.6-300.fc23.x86_64

After compiling dpdk, normally you can find igb_uio here,
dpdk/x86_64-native-linuxapp-gcc/kmod/igb_uio.ko.
Please refer http://www.dpdk.org/doc/guides/linux_gsg/build_dpdk.html.
