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

NAME
     pcidump - show PCI device data

SYNOPSIS
     pcidump [-v] [-x | -xx] [-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 de-
     vices 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.

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

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

HISTORY
     The pcidump utility first appeared in OpenBSD 4.3.

AUTHORS

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