NAME

       __pci_reset_function - 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.

       The device function is presumed to be unused when this function is called. Resetting the device will make the contents of PCI configuration
       space random, so any caller of this must be prepared to reinitialise the device including MSI, bus mastering, BARs, decoding IO and memory
       spaces, etc.

       Returns 0 if the device function was successfully reset or negative if the device doesn't support resetting a single function.

NAME

       scanpci - scan/probe PCI buses

SYNOPSIS

       scanpci [-v12OfV]

DESCRIPTION

       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.
