Get PCI address given a `struct net_device *`

In Linux kernel space, given a struct net_device * how can I get the associated PCI address?

Solution

  • Seems like I found a way. Assuming the network driver creating the net_device does SET_NETDEV_DEV(), then it's possible to get the associated struct pci_dev *pdev = to_pci_dev(netdev->dev.parent) and with that pdev->bus->number which is the PCI bus id, and PCI_SLOT(pdev->devfn) which is the PCI device id.

    Thanks for all the comments btw, extremely useful.
