I am investigating the device tree of the mac99 model. It looks like it is wrong. The part that I am concerned with is the via-cuda node. Both my iMac and iBook don't even have a via-cuda. They both have a via-pmu@16000 node. I'm hoping someone has an original blue and white PowerMac G3. I would like the full device tree printout from it. The question I am trying to answer is does any newworld Mac have a via-cuda? If they don't, we know that it should be changed to a via-pmu@16000 node.

I have one around, and it has a via-cuda@16000 node. There's a power-mgt@0 node at the same level (under mac-io@5) but no pmu node.

With regards to mac99 target I would rather be concerned with lack of /uni-n, as darwin seems to check for this (it panics when checking machine type)
In function Core99PE::start it does a lot of stuff on this device, while power management is just few lines: http://www.opensource.apple.com/source/AppleCore99PE/AppleCore99PE-121.0.2/C...
This machine for example has it: http://web.archive.org/web/20090107152335/http://penguinppc.org/historical/d...

Where is the uni-n node located in the device tree? What is the uni-n node's full name? What are its properties?
Thanks for any help you can provide.

There is no Uni-North on the early G3 Macs. They used Grackle instead.
model PowerMac1,1 compatible PowerMac1,1 MacRISC Power Macintosh
It has:
/pci@80000000 /pci-bridge@s /mac-io@5

Thanks for the info. Did you see any official documentation that said what model the mac99 machine was suppose to emulate? I guess it was the first Blue and White PowerMac G3 because of how close it is to the emulated model.
