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.
Tests
The pcitool reads from the configuration file the devices it expects to find and reports any devices that it cannot find or if the device is
not correct. The tool supports second-source parts; therefore, they are not flagged as false errors. If a mismatch occurs, the device lists
with the expected value and the read value. Populate the configuration file with -u numbers so the device can quickly identify the failing
device.

Usage:
To scan all PCI drivers and optionally show all config data :=
pcitool --scan[=all]
(or)
pcitool -S[=all]
To test using default PCI config-file :=
pcitool --test
(or)
pcitool -t
Show confic data for specific bus:dev.func:=
pcitool --show {--bus=<bus># --dev=<dev># --func=<func>#}
(or)
pcitool -x {-B <bus># -D <dev># -F <func>#}
Read 8-bit config register for bus:dev.func:=
pcitool --read {--bus=<bus># --dev=<dev># --func=<func># --offset=<offset> --count=<count>}
(or)
pcitool -r {-B <bus># -D <dev># -F <func># -O <offset> -C <count>}
Write 8-bit config register for bus:dev.func:=
pcitool --write {--bus=<bus># --dev=<dev># --func=<func># --offset=<offset> --val=<value>}
(or)
pcitool -w {-B <bus># -D <dev># -F <func># -O <offset> -V <value>}
Execute repeatedly command by count:=
pcitool --iteration=max/<count> [option1] [option2]...
(or)
pcitool -I max/<count> [option1] [option2]...
