Hi guys.
While developping the dump modules, I had to find a way to retrieve
the hardware path of disk/hba. So I had to developpe a small hack
in the kernel/firmware.c in order to retrive the right hba.
But it is parisc dependant. Do you want I try to add an ioctl in my
dump modules in order to print in user space this informations ?
Example:

size:1500160 nr_sects:3000320 start_sect:374784
hwpath: 0/0/1/1.15.0.0.
dump device opened: 0x813 with index: 0 at hpa: 0x900

So my functions are able to print the hw path of each io modules.
Is it what you are looking for ?
