Hi Shiva:
Thank you for your reply!
I aslo see the log "DPDK drivers found no ports", but I don't know why
dpdk did not loaded UIO driver。
I use "vppctl show pci" and I can see that the NIC(Intel X710) run
without driver.
I aslo tried to instead uio_pci_generic with vfio_pci, but got the same
relust.(The linux kernel is 3.10.0-1062.4.1.el7.x86_64 CentOs 7.7)
I had a successful test that used uio_pci_generic with linux kernel
3.10.0-327.el7.x86_64 （Centos 7.2）.
Is the dpdk dose not support "Intel Corporation Ethernet Controller
X710" in CentOs 7.7 ?
Or what details did I miss ?
Some tests I did:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
linux kernle version(make vpp use this kernel) | uio-dirver |
vppctl show int | vppctl show pci | vppctl show log
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
3.10.0-1062.4.1.el7.x86_64 (CentOs 7.7) |uio_pci_generic | just
loop0 | NIC without driver | DPDK drivers found no
ports
3.10.0-1062.4.1.el7.x86_64(CentOs 7.7) |vfio-pci |
just loop0 | NIC without driver | DPDK drivers found
no ports
3.10.0-327.el7.x86_64(CentOs 7.2) |uio_pci_generic |
loop0 and tow ints | NIC with uio_pci_generic| OK!
3.10.0-327.el7.x86_64(CentOs 7.2) |vfio-pci
| just loop0 | NIC without driver | DPDK drivers
found no ports

Hi Liu,
You missed binding of NIC devices to uio_pci_generic or vfio driver.
show log confirms the same.
2019/12/31 06:01:42:932 notice dpdk DPDK drivers found no ports
Thanks

Hi everyone:
I can't get NICs when I use "vppctl show interface";
I use "vppctl show pci", and I can see NIC did not have driver info;
What details did I miss ?
I have done these things:
