pcitool
The PCI tool ( pcitool) allows testing of the PCI devices.
In EDA Quick Test mode, pcitool completes a simple check on the PCI bus. The tool scans the PCI bus for all drivers and functions and writes the configuration registers to the configuration file.
Example of the pcitool Output
Syntax: ./pcitool <option>
-h := show this help
scan := scan all PCI devices
all := scan and show all config data
test := test using the default PCI test config file
show <bus# dev# func#> := show config data for a specific bus:dev.func
read <bus# dev# func# offset count> := read 8-bit config register for bus:dev.func
write <bus# dev# func# offset data> := write 8-bit config register for bus:dev.func
Example of the pcitool Configuation File Output
# more default_pci_list.cfg
