On one of my X86-64 systems /proc/interrupts starts with the following
interrupts (per-cpu info snipped):
0: IR-IO-APIC-edge timer
4: IR-IO-APIC-edge serial
8: IR-IO-APIC-edge rtc0
9: IR-IO-APIC-fasteoi acpi
17: IR-IO-APIC-fasteoi ehci_hcd:usb1, hpilo
On this same system /proc/irq shows these interrupts:
0-15, 17
Is there any way to determine what the interrupts are that aren't listed
in /proc/interrupts?
They are simply unused
I wonder if it might be clearer to just not report them at all if
they're not used?
Anyways, thanks for the explanation.
