Some Macs lack a slot interrupt enable register. So the existing code makes disabled and unregistered slot IRQ lines outputs set high. This seems to work on quadras, but does not work on genuine VIAs (perhaps the card still succeeds in pulling the line low, or perhaps because this increases the settle time on the port A input, meaning that the CA1 IRQ could fire before the slot line reads active). Because of this, the nubus_active flags were used to mask IRQs, which is actually worse than the problem it tries to solve. Any interrupt masked by nubus_active will remain asserted and prevent further transitions on CA1. And so the nubus gets wedged regardless of hardware (emulated VIA ASIC, real VIA chip or RBV). The best solution to this hardware limitation of genuine VIAs is to disable the umbrella SLOTS IRQ when disabling a slot on those machines. Unfortunately, this means all slot IRQs get disabled when any slot IRQ is disabled. But it is only a problem when there's more than 1 device using nubus interrupts. Another potential problem for genuine VIAs is an unregistered nubus IRQ. Eventually it will be possible to enable the CA1 interrupt by installing its handler only _after_ all nubus drivers have loaded but _before_ the kernel needs them, at which time this last problem can be fixed. For now it can be worked around: - disable MacOS extensions - don't boot MacOS (use the Emile bootloader instead) - get the bootloaders to disable ROM drivers (Penguin does this for video cards already, don't know about Emile) - physically remove unsupported cards Signed-off-by: NFinn Thain <fthain@telegraphics.com.au> Signed-off-by: NGeert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Make sure that there are no slot IRQs asserted before leaving the nubus handler. If there are and we don't then the nubus gets wedged because this prevents a CA1 transition, which means no more nubus IRQs. Make the interrupt dispatch loops terminate sooner. Explicitly initialise the VIA latches to make the code more easily understood. Also some cleanups.

SCSI should be working on a TT (but someone should really try!) but causes trouble on a Falcon (as in: it ate a filesystem of mine) at least when used concurrently with IDE. I have the notion it's because locking of the ST-DMA interrupt by IDE is broken in 2.6 (the IDE driver always complains about trying to release an already-released ST-DMA). Needs more work, but that's on the IDE or m68k interrupt side rather than SCSI.

These helper functions are a leftover from 2.4 sync I/O and are a notorious source for bugs. They lead to device driver specific code creeping into cio, and some issues can't really be fixed at all.
