Hi John,
If I understand your question correctly, you have multiple NIC ports bound to
the DPDK driver, and of those, you want to bind a specific port to ovs-vswitchd?
It would help me to answer your query more effectively if I had some more
information on what your setup looks like, and what your desired OVS end-state
configuration is, but this answer should provide some general guidance.
To provide some context, consider how the DPDK port enumeration process works,
which is (roughly) as follows:
- as part of the DPDK init process, PCI devices are enumerated
- enumerated devices are typically ordered from low-to-high by PCI
Bus:Device:Function
- for each compatible PCI function detected, DPDK checks if that PCI device is
bound to a supported DPDK driver
- if so, that device is assigned a port ID, starting from 0 for the lowest PCI
ID, and increasing to 1 for the next PCI ID, and so on
- for more information, consult DPDK documentation and/or the DPDK mailing list
In your case, you have (presumably) two PCI functions/NIC ports bound to a DPDK
driver; on init, these devices are enumerated/indexed as 0 and 1, respectively.
Consequently, to add DPDK port 'N' to a bridge, simply run:
'ovs-vsctl add-port br0 dpdkN -- set Interface dpdkN type=dpdk'
Where N = the index of the DPDK device port, as enumerated by DPDK on init.
I hope this helps.
Cheers,
Mark
