PCI_RESET_FUNCTION(9)                  Hardware Interfaces                  PCI_RESET_FUNCTION(9)



NAME
       pci_reset_function - quiesce and reset a PCI device function

SYNOPSIS
       int pci_reset_function(struct pci_dev * dev);

ARGUMENTS
       dev
           PCI device to reset

DESCRIPTION
       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.
