So I have a patch to try and straighten out the ppbus/ppc interrupt stuff a bit. Rather than passing IRQ numbers around as ivars, etc., ppc is smart enough to let child devices ask for SYS_RES_IRQ rid 0 and let them use its assigned IRQ resource. It then uses an interrupt event to mange the list of child interrupt handlers which it invokes from its own interrupt handler. I don't currently have any boxes running HEAD that have anything hooked up to their ppc0 port, so I'd appreciate folks testing this if possible. http://www.FreeBSD.org/~jhb/patches/ppc_intr.patch -- John Baldwin
