Hi,
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 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 17
Is there any way to determine what the interrupts are that aren't listed in /proc/interrupts? Six of them are affined to all CPUs, and I'm trying to affine as many interrupts as possible to housekeeping CPUs to free up application CPUs for low-latency operations.
I'm not subscribed to the list, so I'd appreciate being CC's on any replies.
Chris
