/* To disable a NuBus slot on Quadras we make that slot IRQ line an output set
* high. On RBV we just use the slot interrupt enable register. On Macs with
* genuine VIA chips we must use nubus_disabled to keep track of disabled slot
* interrupts. When any slot IRQ is disabled we mask the (edge triggered) CA1
* or "SLOTS" interrupt. When no slot is disabled, we unmask the CA1 interrupt.
* So, on genuine VIAs, having more than one NuBus IRQ can mean trouble,
* because closing one of those drivers can mask all of the NuBus interrupts.
* Also, since we can't mask the unregistered slot IRQs on genuine VIAs, it's
* possible to get interrupts from cards that MacOS or the ROM has configured
* but we have not. FWIW, "Designing Cards and Drivers for Macintosh II and
* Macintosh SE", page 9-8, says, a slot IRQ with no driver would crash MacOS.
/*
* On Macs with a genuine VIA chip there is no way to mask an individual slot
* interrupt. This limitation also seems to apply to VIA clone logic cores in
* Quadra-like ASICs. (RBV and OSS machines don't have this limitation.)
*
* We used to fake it by configuring the relevent VIA pin as an output
* (to mask the interrupt) or input (to unmask). That scheme did not work on
* (at least) the Quadra 700. A NuBus card's /NMRQ signal is an open-collector
* circuit (see Designing Cards and Drivers for Macintosh II and Macintosh SE,
* p. 10-11 etc) but VIA outputs are not (see datasheet).
*
* Driving these outputs high must cause the VIA to source current and the
* card to sink current when it asserts /NMRQ. Current will flow but the pin
* voltage is uncertain and so the /NMRQ condition may still cause a transition
* at the VIA2 CA1 input (which explains the lost interrupts). A side effect
* is that a disabled slot IRQ can never be tested as pending or not.
*
* Driving these outputs low doesn't work either. All the slot /NMRQ lines are
* (active low) OR'd together to generate the CA1 (aka "SLOTS") interrupt (see
* The Guide To Macintosh Family Hardware, 2nd edition p. 167). If we drive a
* disabled /NMRQ line low, the falling edge immediately triggers a CA1
* interrupt and all slot interrupts after that will generate no transition
* and therefore no interrupt, even after being re-enabled.
*
* So we make the VIA port A I/O lines inputs and use nubus_disabled to keep
* track of their states. When any slot IRQ becomes disabled we mask the CA1
* umbrella interrupt. Only when all slot IRQs become enabled do we unmask
* the CA1 interrupt. It must remain enabled even when cards have no interrupt
* handler registered. Drivers must therefore disable a slot interrupt at the
* device before they call free_irq (like shared and autovector interrupts).
*
* There is also a related problem when MacOS is used to boot Linux. A network
* card brought up by a MacOS driver may raise an interrupt while Linux boots.
* This can be fatal since it can't be handled until the right driver loads
* (if such a driver exists at all). Apparently related to this hardware
* limitation, "Designing Cards and Drivers", p. 9-8, says that a slot
* interrupt with no driver would crash MacOS (the book was written before
* the appearance of Macs with RBV or OSS).
