-t              Show bus tree

 

Display options:

-v              Be verbose (-vv for very verbose)

-k              Show kernel drivers handling each device

-x              Show hex-dump of the standard part of the config space

-xxx            Show hex-dump of the whole config space (dangerous; root only)

-D              Always show domain numbers

 

Resolving of device ID's to names:

-n              Show numeric ID's

-nn             Show both textual and numeric ID's (names & numbers)

-q              Query the PCI ID database for unknown ID's via DNS

-qq             As above, but re-query locally cached entries

-Q              Query the PCI ID database for all ID's via DNS

 

Selection of devices:

-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]   Show only devices in selected slots

-d [<vendor>]:[<device>]                        Show only devices with specified ID's

 

Other options:

-i <file>       Use specified ID database instead of /usr/share/misc/pci.ids.gz

-p <file>       Look up kernel modules in a given file instead of default modules.pcimap

-M              Enable `bus mapping' mode (dangerous; root only)

 

PCI access options:

-A <method>     Use the specified PCI access method (see `-A help' for a list)

-O <par>=<val>  Set PCI access parameter (see `-O help' for a list)
