I just committed a change to HEAD to add a new flag to pciconf to dump VPD data. If you just need it in a shell script then 'pciconf -lV <device>' might be sufficient for you. If you want it programmatically, you can use the new ioctl I added to retrieve it from the kernel. If you need to do this on an older OS version where you can't backport my change (or upgrade to a version with this change), then you can use direct config register access to find the VPD capability and read the data directly using the VPD registers. -- John Baldwin
