> sio1: configured irq 3 not in bitmap of probed irqs 0
I would assume it means that 0x00000000 is the bitmap of probed irqs and that
irq3 0x10 configured for sio1 is not in that bitmap.
isa/sio.c:
/*
* Turn off all device interrupts and check that they go off properly.
* Leave MCR_IENABLE alone. For ports without a master port, it gates
* the OUT2 output of the UART to
* the ICU input. Closing the gate would give a floating ICU input
* (unless there is another device driving it) and spurious interrupts.
* (On the system that this was first tested on, the input floats high
* and gives a (masked) interrupt as soon as the gate is closed.)
*/
sio_setreg(com, com_ier, 0);
sio_setreg(com, com_cfcr, CFCR_8BITS); /* dummy to avoid bus echo */
failures[7] = sio_getreg(com, com_ier);
DELAY(1000); /* XXX */
irqmap[3] = isa_irq_pending();
failures[9] = (sio_getreg(com, com_iir) & IIR_IMASK) - IIR_NOPEND;
enable_intr();
irqs = irqmap[1] & ~irqmap[0];
if (bus_get_resource(idev, SYS_RES_IRQ, 0, &xirq, NULL) == 0 &&
((1 << xirq) & irqs) == 0)
printf(
"sio%d: configured irq %ld not in bitmap of probed irqs %#x\n",
device_get_unit(dev), xirq, irqs);
