Hi Stephen,
if I don't give the last option for socket memory then also it fails.
Here is the error log :-

Hi Monika,
> For last command I just declared 10 hugepages.
This is not enough.
I would suggest that you will try with 256 pages.
I assume you have 2 sockets on the host (this can be verified by running "lspcu") and use 2MB hugepages.
So, this can be done by:
echo 256 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
and
echo 256 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
And run the same command that you used to launch testpmd.
(And if testpmd will still fail, please post the output of
cat /proc/meminfo | grep -i huge)
Also for the future, this type of queries should be posted on dpdk-users mailing list.
Regards,
Rami Rosen

Hi Stephen
For last command I just declared 10 hugepages.
