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 :-

======================================================================
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 3  [0, 12]         [1, 13]
Core 4  [2, 14]         [3, 15]
Core 5  [4, 16]         [5, 17]
Core 6  [6, 18]         [7, 19]
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

How much huge page memory did you confirm?
$ cat /proc/meminfo

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.
