E.3.3. /proc/bus/pci
Later versions of the 2.6 Linux kernel have obsoleted the
/proc/pci directory in favor of the /proc/bus/pci directory. Although you can get a list of all PCI devices present on the system using the command cat /proc/bus/pci/devices, the output is difficult to read and interpret.
For a human-readable list of PCI devices, run the following command:
~]# /sbin/lspci -vb

[output truncated]
The output is a sorted list of all IRQ numbers and addresses as seen by the cards on the PCI bus instead of as seen by the kernel. Beyond providing the name and version of the device, this list also gives detailed IRQ information so an administrator can quickly look for conflicts.
