John,
I do not have an environment that you are persuing, ie.
Qemu.
So you will need to clarify a little
more.
Do you have a running OpenBIOS system such that you get to
the
OpenFirmware console specifically at the "ok"
prompt?

Yes, that's essentially what I want. The runiso target
in the makefile uses qemu. So that part was easy.
Trying to decipher all the rest of it is where I'm
stuck.

John,
Exercising the PCI config space is probably what you
are looking to do.
Have you actually been able to install OpenBIOS in
your Qemu environment/platform?

I am investigating
the possiblity of using Openbios as a tool to verify our custom PCI
designs.
Specifically what
I am interested in is the ability to modify the PCI base address registers and
excercise the address decoders on the cards. What I'm after is some basic PCI
compliance testing that is hard to do with a full blown
OS.
My problem is that
I'm having a tough time with the learning curve of openbios. I'm having
trouble figuring out how to do some basic things, like query the BARs of a PCI
device. I'm using Qemu as a sandbox to play with openbios, but I can't even
figure out how print the value of configuration register zero of a particular
device!
Can anyone steer
me in the right direction? Am I wasting my time, or does it sound like
Openbios is going to do what I want.
Thanks,
John
