[dpdk-users] Intel SRIOV Virutalization using DPDK

[Anupama Laxmi <anupamalaxmi4@gmail.com>]

Hi,

These are the 10 G NIC cards on the host machine:

lspci | grep 10-G

04:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+
Network Connection (rev 01)
04:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+
Network Connection (rev 01)

*One Physical Function * per Intel® 82599 10 Gigabit Ethernet Controller
NIC port and *63 Virtual Functions* assigned to each physical function.

With DPDK  SRIOV  the application  on the guest machine during
initilailization does pci probe and get the internal pci address of the
Virtual functions (assigned to the VM).

Below DPDK API's being used:

rte_eal_init

rte_pci_probe()

rte_eth_dev_count();

Based on the  virtual function pci address/ mac address or other means I
want to obtain the physical NIC port its assigned to on the host machine.

Is there a way to determine the physical function/physical port from the
virtual function based on system  commands  or  DPDK api's ?



Also can these 10G NIC cards/ports  be UP at the same time ?

Can Virtual Machine scan the Vf's from both 10 G NIC cards at the same time
?

Or only one of those 10G NIC cards can be UP at a time ?



Please let me know.


Best Regards,
Anupama
