Dear all,
I am a beginner with DPDK.
I just install it in fedora18 with two X540 Enthercards.
After compile it and run the testpmd I got the following message:
[root at localhost test-pmd]# ./testpmd -c7 -n3 -- -i --nb-cores=2
Thanks Prashant

Hi all,
In the documentation available on DPDK, I could find the performance numbers in
terms of packets per second. Could someone point me to some documentation
which gives performance gain of round trip time or packet processing time in
terms of time, say, usecs?
Also, what is the tool tha
Hi,
Is the rte_mbuf/packet data always map to a contiguous area in memory, and
so if I can do a linear copy of it ?
Cheers,

No, in scatter/gather case, mbuf can be splitted in non contiguous areas.

Thomas,
Thank you for the information. Because I would like to copy an rte_mbuf to
a memory mapped file for an application. Is there some dpdk API for this
copy operation (linear/nonlinear) or are these left with the application
developers ?
Thanks,
Pepe

You should send your patch to kernel.org via the netdev mailing list:

Hi Thomas,
Thanks for your answer. I'll try to send the patch to netdev list and
let you know the result.
BTW, I double checked 82598 and find that it doesn't have mailbox at
all, meaning this patch is for 82599 and X540 only.
So the test is only needed for X540.
thx &
