[dpdk-users] Retrieve NIC vendor name using PCI vendor ID

[dpdk-users] Retrieve NIC vendor name using PCI vendor ID

[george.dit]

Hi all,

I would like to ask how one could retrieve the name of a NIC's vendor using
the PCI vendor ID.
For example, is there any mapping between PCI_VENDOR_ID_INTEL and a const
char* that returns e.g., "Intel"?

Moreover, why are the vendor IDs redefined by DPDK instead of being reused
from Linux
<https://github.com/torvalds/linux/blob/master/include/linux/pci_ids.h>?
It would be more convenient if a single RTE library could expose those IDs
to the applications. Currently I see those IDs being spread across the
different drivers.

Thanks in advance,

There already is a standard library for this (libpci).
I see no reason to add this to DPDK.

Hi, George,

+1.

Follow in pciutils execution of, for example,
"lspci -d 8086:158b"
Where you get, for example:
03:00.0 Ethernet controller: Intel Corporation Device 158b (rev 02)
(or any other vendrID:DeviceID combo).

I would guess that behinds the scenes it is done by pci_lookup_name():
https://github.com/pciutils/pciutils/blob/master/lib/names.c#L122

Hi Stephen and Rami,

I see your point, libpci seems to be the way to go.

Thanks,
Georgios
