[dpdk-users] wrong vermagic in igb_uio.ko

[O Mahony, Billy]

Hi,

I have two kernels installed on my system. One with some local patches applied.

4.9.30-rt20
And
4.9.30-rt20-timers-patch

But regardless of which kernel I boot with when I build DPDK igb_uio always has 
vermagic from just one kernel. 4.9.30-rt20. Even though the build puts it in a 
correctly named path.

    # modinfo 
./install/lib/modules/4.9.30-rt20-timers-patch/extra/dpdk/igb_uio.ko | grep -i 
magic
    vermagic:       4.9.30-rt20 SMP preempt mod_unload
    # uname -r
    4.9.30-rt20-timers-patch

I can't see any kernel/vermagic configuration in the various config files. I'm 
pretty sure I'd figured out before that the dpdk build was pulling this info 
from /usr/src/linux/.config CONFIG_LOCALVERSION setting but it seems to be 
ignoring anything I put in that now.

Where /does/ the dpdk build get the kernel version info from? 

Cheers,
Billy
