Hello.
Does OpenBSD 3.8 use the APIC (Advanced Programmable Interrupt
Controller) ?
Some cards, e,g telephony and framegrabbers have issues with the
limited standard XT 16 IRQ's.
APIC motherboards give you 24 or more (I've seen as many as 101)
interrupts.
Besides doing a dmesg | grep irq, is there another way at seeing the
assigned interrupts. e.g. For Linux cat /proc/interrupts reveals:-
Dell PowerEdge 2850 (dual Xeon)
cat /proc/interrupts
CPU0 CPU1
0: 6184515 72 IO-APIC-edge timer
1: 8 1 IO-APIC-edge i8042
9: 0 0 IO-APIC-level acpi
12: 65 1 IO-APIC-edge i8042
14: 11 2 IO-APIC-edge ide0
46: 19595 1 IO-APIC-level megaraid
64: 66366 1 IO-APIC-level eth0
65: 77045 1 IO-APIC-level eth1
101: 6113521 1 IO-APIC-level wctdm
