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.

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