SCANPCI(1)              FreeBSD General Commands Manual             SCANPCI(1)

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.
