I have the need to have two of my PCI devices on their own IRQ, this
is my current interrupts setup:
[root at watson ~]# cat /proc/interrupts
CPU0
0: 144 IO-APIC-edge timer
1: 2 IO-APIC-edge i8042
8: 19 IO-APIC-edge rtc0
9: 0 IO-APIC-fasteoi acpi
12: 4 IO-APIC-edge i8042
14: 0 IO-APIC-edge ata_piix
15: 930 IO-APIC-edge ata_piix
16: 34390 IO-APIC-fasteoi uhci_hcd:usb2, uhci_hcd:usb5, nvidia
18: 18003 IO-APIC-fasteoi ata_piix, uhci_hcd:usb4
19: 0 IO-APIC-fasteoi uhci_hcd:usb3
20: 0 IO-APIC-fasteoi ivtv1
21: 6694 IO-APIC-fasteoi EMU10K1, ivtv2, eth1
23: 7305 IO-APIC-fasteoi ehci_hcd:usb1, ivtv0
NMI: 0 Non-maskable interrupts
LOC: 145472 Local timer interrupts
RES: 0 Rescheduling interrupts
CAL: 0 function call interrupts
TLB: 0 TLB shootdowns
TRM: 0 Thermal event interrupts
SPU: 0 Spurious interrupts
ERR: 0
MIS: 0
I watch each of the ivtv devices on their own IRQ. As of now, all the
changes I've made at the BIOS level have failed. Is it possible assign
these at the OS level?
