Hi Anatoly I'm using dpdk-1.6.0r2 on Ubuntu 12.04 LTS with kernel 3.11.0-20-generic #35~precise1-Ubuntu SMP
As for further investigation: 1. It doesn't matter whether DPDK uses 1GB or 2MB hugepages. 2. dmesg messages appear only when I invoke "start tx_first" in testpmd app (so only when I try to send some packets) The setup is very easy. 2 NICs connected with each other (port0 on NIC1 to port0 on NIC2, same for port1). Each NIC iis on different server Thanks Tomasz 2014-05-07 16:45 GMT+02:00 Burakov, Anatoly <anatoly.burakov at intel.com>: > Hi Tomasz, > > > > > Here lies your mistake :-) Boot your kernel with iommu to "pt" (iommu=pt > > intel_iommu=on) and everything will work.
