PCIDUMP(8)		OpenBSD System Manager's Manual		    PCIDUMP(8)

NAME
     pcidump - show PCI device data

SYNOPSIS
     pcidump [-v] [-x | -xx | -xxx] [-d pcidev] [bus:dev:func]
     pcidump -r file [-d pcidev] bus:dev:func

DESCRIPTION
     The pcidump utility displays the device address, vendor, and product name
     of PCI devices.  When no arguments are given, information on all PCI
     devices in the system is shown; otherwise a single PCI domain or device
     may be specified.

     The options are as follows:

     -d pcidev
	     Specify a file to use for PCI lookups.  If specified without
	     bus:dev:func, all PCI devices in the domain will be shown.

     -r file
	     Reads the PCI ROM from the device specified by bus:dev:func, and
	     writes its contents to file.

     -v	     Shows detailed information about PCI devices.

     -x	     Shows a hexadecimal dump of the first 64 bytes of PCI config
	     space.

     -xx     Shows a hexadecimal dump of the full PCI config space.

     -xxx    Shows a hexadecimal dump of the PCIe extended config space.

     bus:dev:func
	     Show information about the PCI device specified by the tuple
	     given on the command line.	 If the -d option is not given,
	     /dev/pci is used.

FILES
     /dev/pci*	Device files for accessing PCI domains.

SEE ALSO
     pci(4)

HISTORY
     The pcidump utility first appeared in OpenBSD 4.3.

AUTHORS
     The pcidump utility was written by David Gwynne <dlg@openbsd.org>.

BUGS
     The default behaviour of scanning all PCI domains is limited to those
     domains that have an entry in /dev.
