prtpci: digest and display prtconf -pv output

Here's a tool (prtpci.tar.Z) for digesting PCI information from prtconf -pv output.

There are several tools around that will show you a PCI manifest; this one

• is safe, doesn't poke at machine ports to do its job
• can be run offline with a captured prtconf -pv file
• makes use of the common "pci.ids" database from Sourceforge, and includes a script to update that database periodically
• decodes the Base Address Registers (BARs) and slot-names properties
• is written in Perl for easy hackability

It's useful to me, and I hope it is useful to you. Here's a little sample output:
