Re: [dpdk-users] Issue on running kni application

Hi

I was about to say that , you have to change(increase) the hugepages. To be
simple , please follow the below step to increase number of hugepages(from
my script) and then run your KNI app.


#setting huge pages for DPDK program
mkdir -p /mnt/huge

mount -t hugetlbfs nodev /mnt/huge

echo 1024 >
/sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

you can cross check (last few lines):  cat /proc/meminfo
