Yes, this is how it's wired in qemu too. But I meant the OBP level. What worries me is that this construction seems to be never used in sun4u OBP:
$ grep interrupts linux/kernel/git/davem/prtconfs/* | grep -c 00000001 402 $ grep interrupts linux/kernel/git/davem/prtconfs/* | grep -c 00000000 2
And the both hits are sun4v:
$ grep interrupts ~/openbios/linux/kernel/git/davem/prtconfs/* | grep 00000000 linux/kernel/git/davem/prtconfs/t1000: interrupts: 00000000 linux/kernel/git/davem/prtconfs/t2000_1: interrupts: 00000000
Can it be, that 0 is (or used to be) some magic constant?
I'll check on monday and get back to you.
