1 Watchdog timer:Can generate a system reset or IRQ 15.

2 There is an IRQ or I/O address conflict, the system can lock up.

3 How do I know if an IRQ or exception is firing?

4 Registers and releases, respectively, a callback an IRQ line. The registration can be exclusive or shared.

5 You can then assign a different IRQ to that network card.

6 The IRQ signal is delivered to the local APICs listed in the corresponding Redirection Table entry.

7 Under ARM architecture, hardware generated external interrupts ( IRQ ) have one single entry point.

8 You'll also find variants of reader/writer spinlocks for bottom halves and interrupt request (IRQ) saving depending on the situation for which you require the lock.

9 Normally, each device needs a dedicated IRQ ( except for USB and some PCI devices ) .

10 The IRQ signal is delivered to the local APIC of the processor that is executing the process with the lowest priority.

11 CPU on the 8279 surveillance using the query mode,[] the 8279 interrupt request signal IRQ left unused.

12 Registers and releases, respectively, a callback handler for an IRQ line. The registration can be exclusive or shared.

13 Note that to identify the handler, the kernel needs both the IRQ number and the device identifier.
