68 * genuine VIA chips we must use nubus_disabled to keep track of disabled slot 68 * On Macs with a genuine VIA chip there is no way to mask an individual slot
69 * interrupts. When any slot IRQ is disabled we mask the (edge triggered) CA1 69 * interrupt. This limitation also seems to apply to VIA clone logic cores in
70 * or "SLOTS" interrupt. When no slot is disabled, we unmask the CA1 interrupt. 70 * Quadra-like ASICs. (RBV and OSS machines don't have this limitation.)
71 * So, on genuine VIAs, having more than one NuBus IRQ can mean trouble, 71 *
72 * because closing one of those drivers can mask all of the NuBus interrupts. 72 * We used to fake it by configuring the relevent VIA pin as an output
73 * Also, since we can't mask the unregistered slot IRQs on genuine VIAs, it's 73 * (to mask the interrupt) or input (to unmask). That scheme did not work on
74 * possible to get interrupts from cards that MacOS or the ROM has configured 74 * (at least) the Quadra 700. A NuBus card's /NMRQ signal is an open-collector
75 * but we have not. FWIW, "Designing Cards and Drivers for Macintosh II and 75 * circuit (see Designing Cards and Drivers for Macintosh II and Macintosh SE,
76 * Macintosh SE", page 9-8, says, a slot IRQ with no driver would crash MacOS. 76 * p. 10-11 etc) but VIA outputs are not (see datasheet).
77 *
78 * Driving these outputs high must cause the VIA to source current and the
79 * card to sink current when it asserts /NMRQ. Current will flow but the pin
80 * voltage is uncertain and so the /NMRQ condition may still cause a transition
81 * at the VIA2 CA1 input (which explains the lost interrupts). A side effect
82 * is that a disabled slot IRQ can never be tested as pending or not.
83 *
84 * Driving these outputs low doesn't work either. All the slot /NMRQ lines are
85 * (active low) OR'd together to generate the CA1 (aka "SLOTS") interrupt (see
86 * The Guide To Macintosh Family Hardware, 2nd edition p. 167). If we drive a
87 * disabled /NMRQ line low, the falling edge immediately triggers a CA1
88 * interrupt and all slot interrupts after that will generate no transition
89 * and therefore no interrupt, even after being re-enabled.
90 *
91 * So we make the VIA port A I/O lines inputs and use nubus_disabled to keep
92 * track of their states. When any slot IRQ becomes disabled we mask the CA1
93 * umbrella interrupt. Only when all slot IRQs become enabled do we unmask
94 * the CA1 interrupt. It must remain enabled even when cards have no interrupt
95 * handler registered. Drivers must therefore disable a slot interrupt at the
96 * device before they call free_irq (like shared and autovector interrupts).
97 *
98 * There is also a related problem when MacOS is used to boot Linux. A network
99 * card brought up by a MacOS driver may raise an interrupt while Linux boots.
100 * This can be fatal since it can't be handled until the right driver loads
101 * (if such a driver exists at all). Apparently related to this hardware
102 * limitation, "Designing Cards and Drivers", p. 9-8, says that a slot
103 * interrupt with no driver would crash MacOS (the book was written before
104 * the appearance of Macs with RBV or OSS).
