RE: AIX device driver and PCI board location

["John R Pierce" <pierce@scruznet.com>]

This is problematical for unix systems.  The base addresses
of any PCI peripherals is determined by the system BIOS at
bootup time, and can change if any hardware in the system
is added or changed.  Normally, a PCI device driver locates
the correct device by utilizing 'find device' pci bios calls...  I'm not
quite
sure how this translates to the PPC boot up environment, tho.

Subject: 	AIX device driver and PCI board location

I have written a device driver for: 

  IBM Power-PC
  AIX 4.1
  PCI board
   

The problem: How do I specify the physical location of the PCI board (or do
the
             system find it by itself?).

In detail:
When I add the device information with the 'mkdev' command, one option is 
the '-w ConnectionLocation'. What do I put in there?

The result of the 'mkdev' command is an entry in the 'Customised Device'
(CuDv) 
database. The CuDv shall contain the variables 'location' and 'connwhere'.

How to I find proper values for these variables?

All help is appreciated.

Hans
