PCI_RESET_FUNCTION(9) Hardware Interfaces PCI_RESET_FUNCTION(9)NAME
pci_reset_function - quiesce and reset a PCI device function
int pci_reset_function(struct pci_dev * dev);
PCI device to reset
Some devices allow an individual function to be reset without affecting other functions in the same device. The PCI device must be
responsive to PCI config space in order to use this function.
This function does not just reset the PCI portion of a device, but clears all the state associated with the device. This function differs
from __pci_reset_function in that it saves and restores device state over the reset.
Returns 0 if the device function was successfully reset or negative if the device doesn't support resetting a single function.

scanpci - scan/probe PCI buses
Scanpci is a utility that can be used to scan PCI buses and report information about the configuration space settings for each PCI device.
On most platforms, scanpci can only be run by the root user.
OPTIONS -v Print the configuration space information for each device in a verbose format. Without this option, only a brief description is
printed for each device.
-x Show hexadecimal dump of the first 64 bytes of each PCI device's configuration space. For CardBus bridges, the first 128 bytes are
dumped instead. This option can be repeated to dump all 256 or 4096 bytes, but doing so might cause scanpci (or the system) to
crash because some devices cannot tolerate reads of undefined portions of their configuration space.
-1 Use PCI config type 1.
-2 Use PCI config type 2.
-f Used in conjunction with the above two options, this forces the specified configuration type to be used for config space access.
-O Use the OS's PCI config space access mechanism to access the PCI config space (when available).
-V n Set the verbosity level to n for the internal PCI scanner. This is primarily for debugging use.
