pcitool
To scan and access devices on the PCI bus, use the pcitool. The pcitool checks for missing devices and that the present devices
are the proper type.
The pcitool scans the PCI bus for present devices and displays them and the BAR information it decodes. The tool does not handle
endianess.
The pcitool reads the configuration file and then iterates across all devices in the configuration file. It checks the vendor/product ID to
see that the correct device is at the correct address. The tool does not compare all the configuration space. The tool reads all 256 bytes
of the configuration file.
