hi,

I'm trying to debug a kernel panic. I'd like to lookup the meaning of

the

codes contained in the DSISR, MSR and DAR.

Exception state (sv=0x0DC62C80)

PC=0x90000E2C; MSR=0x0000D030; DAR=0x0DCDB000; DSISR=0x42000000;

LR=0x0001

PC = Program Counter. This is actually r2 (I think) since the PPC does not actually have a PC register. DAR = Data register, this is usually r3, or the first arg to a function call. LR = Link Register which should be the previous function in the call stack. I forget what MSR and DSISR are.

Can anybody point me at some on-line powerpc docs which would help out?

You can look at Motorola's web site for doc on the PPC, also look at Apple's site. I know the PC counter is non-std, but I forget if r3 is the std register for function args. HTH.
