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