[dpdk-dev] Specific NIC for DPDK?

[dpdk-dev] Specific NIC for DPDK?

[TSADOK, Shlomi (Shlomi)]

Hello

A quick general question:

Is there a requirement for using a specific NIC/Chipset for DPDK or any NIC will do?

If there's such a requirement, why is that? Are the're any hardware optimizations etc. in DPDK enabled NICs?

Thanks

Shlomi

Hi Shlomi,

Currently DPDK supports most of Intel 1Gb and 10Gb NICs. The exact list can
be found at lib/librte_eal/common/include/rte_pci_dev_ids.h

The reason is the the DPDK includes a poll mode driver and for a different
NIC you might need a different poll mode driver.

Daniel Kaminsky

There are more supported NICs than in rte_pci_dev_ids.h.
Please have a look at the online documentation:
	http://dpdk.org/doc/nics

Thanks guys

So basically "only" Intel* and mlx4 are supported? Do I get it right?

Yes, they are the poll mode drivers for hardware NICs.
Note that pcap should allow to run DPDK with other NICs but without 
performance gain.

You could write a PMD for any NIC. The work is only done for the NICs listed here http://dpdk.org/doc/nics
But nothing stopping anyone from using other NICs if they want to write the PMD.
