[dpdk-dev] Testpmd fails in initialization

[Monika Mails <mails.monika@gmail.com>]

Hi All,

This is Monika.
I am new to DPDK.
I just installed DPDK release - 18.05 on my server and trying to run
"testpmd"

Here is my command and its output :-

 sudo testpmd -l 8 -n 4 -c 0x3 --socket-mem=512,512

Here are the other details of my server :-

*./deps/dpdk-18.05/usertools/cpu_layout.py*
======================================================================
Core and Socket Information (as reported by '/sys/devices/system/cpu')
======================================================================

cores =  [3, 4, 5, 6, 10, 11]
sockets =  [0, 1]

        Socket 0        Socket 1

Core 10 [8, 20]         [9, 21]
Core 11 [10, 22]        [11, 23]

I tried selecting different number of hugepages from 1024-10, but getting
the same initialization error.
Can someone please suggest some resolution.
Appreciate some advice.

Regards,
Monika
