[dpdk-ovs] Problem with OVS

[dpdk-ovs] Problem with OVS

[Romulo Rosa]

Hi,

i'm tryin to run OVS and i get a error. In documentation was mentioned a
possible solution for this problem but it didnt work to me. Someone have
any idea how to solve this problem?
The uio module is loaded.

*Command: *./datapath/dpdk/build/ovs_dpdk -c 0xf -n 4 -- -p 0xc -n 2 -k 2
--stats=1 --vswitchd=0 --client_switching_core=1 --config="(0,0,2),(1,0,3)"

*Error: *

I think you have the wrong port mask.  Try using -p 0x3.

Thanks Paul,

But i think my NICS are not supportted by Intel DPDK. In this link they are
not listed http://dpdk.org/doc/nics. Anyone know if there are other
supported cards?

Hi Romulo

You can check lib/librte_eal/common/include/rte_pci_dev_ids.h for supported
NICs.
Also from your pci_unbind status , does not look like any NIC is bound to
igb_uio..

No, Broadcom and Emulex NICs are not supported. But patches are welcomed.

By the way, you can use any NIC with pmd_pcap if you don't care about 
performance.

 Unfortunately performance is something I need for my graduate work. I also do
not have much time to develop a patch at the moment, maybe in a master's
thesis.
Thanks
