Hi,
I am stuck with porting the Fiasco microkernel to PowerPC. I can't find any clear documentation about how to setup a interrupt description table. So, these are my questions:
1. How is an interrupt descriptor formed on PowerPC? How does it look? 2. Where (in memory) do I need to store these descriptors?
The IBM PowerPC Programming Manual gives me a good overview but no information on how to implement it. Can someone please point me to some meaningful documentation?
Regards,
Matthias.

Book III contains a section where the interrupt descriptors seem to be specified as detailed as you need.

For specific questions you might find the usenet group comp.sys.powerpc.tech interesting. I guess there are some people that can provide in-depth information.
