[Adeos-main] Porting question

[Reynolds, Terry \(Contractor-SIMTECH\)]

My apologies for being vague!  I'd never looked at the 2.4 tree & didn't know 
there was a ppc port there, I'm working on a ppc64, 2.6 port.
 
I have a newfound appreciation for everyone porting ppc drivers to ppc64, the 
differences are huge.
 
My specific problem is in using the RTAI sample test (latency), via the 
adeos/generic.c implementation.   In adeos_register_domain, when the root 
domain (linux) calls the adeos_switch_to function, the link register value 
stored for the RTAI_hal domain isn't set up properly to return to the 
register_domain function.
 
At least I assume that's what's happening, since my system crashes in the 
adeos_switch_domain function, or in returning from there.
 
This would be much easier to work on if there was a kdb available for ppc64!  
Printk statements, with the kernel crashing every time I run the program is 
very time consuming.
 
My question is: in the process of registering a domain, when does it's stack 
get setup so that a call to switch domain will pull up the correct value to 
place in the link register so that the switch function will know where to 
return to?
 
 
Thanks,
