Interrupt Handling

The Solaris 9 DDI/DKI addresses these aspects of device interrupt handling:

• Registering device interrupts with the system

• Removing device interrupts

• Dispatching interrupts to interrupt handlers

Device interrupt sources are contained in a property called interrupt, which is either provided by the PROM of a self-identifying device, in a hardware configuration file, or by the booting system on the IA platform.
