Interrupt Handling (cont)
Soft Interrupts:
- Soft interrupt system works similarly to hardware interrupt
system
- But soft interrupts are triggered by a DDI/DKI call
rather than a device
- Soft interrupts are not high-level, and run on interrupt
threads
- A high-level interrupt routine might delegate most
of its processing work to a soft interrupt routine it triggers
- See Also: ddi_add_softintr(9F), ddi_trigger_softintr(9F)
