I was looking at the code used to tie together the bios drive numbers
for hard disks with the netbsd device driver/unit name.
The PCI bios will (bugs excepted) tell us where it found a particular
disk - eg ATA on pci bus 0 device 5 function 1.
However I can't spot a way of getting the same information out of
the netbsd device tree - eg starting from alldevs.
The 'bus type' and 'locators' seem to be absent from the referenced
What have I missed?
these infos aren't stored, in general. this is why people recent
have noted they can write a program to dump the device tree but
there has been discussion on changing this in the past, and i think
it would be a good idea (but see generic/device properties.)
