I have a CAN PCI card installed on my Ubuntu box.
I understand that PCI interrupts should be level rather than edge
triggered.
The output of cat /proc/interrupts is :-
CPU0
0: 1614601 IO-APIC-edge timer
1: 164 IO-APIC-edge i8042
8: 3 IO-APIC-edge rtc
9: 1 IO-APIC-level acpi
12: 0 IO-APIC-edge CAN-ACx-PCI_01
14: 65786 IO-APIC-edge ide0
169: 3220 IO-APIC-level eth0, [EMAIL PROTECTED]:0000:00:02.0
177: 46459 IO-APIC-level eth1
209: 0 IO-APIC-level uhci_hcd:usb3, eth2
217: 2 IO-APIC-level uhci_hcd:usb1, ehci_hcd:usb4
225: 697 IO-APIC-level uhci_hcd:usb2
NMI: 0
LOC: 1614399
ERR: 0
MIS: 0
You see that irq 12 CAN-ACx-PCI_01 is edge triggered.
Is there any way of forcing the BIOS to see the interrupt as a
level-triggered one?
