Use … WebFor each interrupt type that you allocate, take the following steps: Use ddi_intr_get_pri (9F) to get the priority for the interrupt. If you need to set a new priority for the interrupt, use ddi_intr_set_pri (9F). Use mutex_init (9F) to initialize the lock. Use ddi_intr_add_handler (9F) to register the handler for the interrupt.

WebAug 20, 2024 · @PeterCordes FWIW, the LAPIC Timer is a count-down timer. It works as you said. The HPET (High Precision Event Timer) is a count-up but has a set of 8 comparators for each of its 32 timers (so a count-up makes sense in this context). The PIT, the legacy timer on x86, has three count-down counters. So I remembered wrong. … WebRegister Timer interrupt handler, the handler is an ISR. The handler will be attached to the same CPU core that this function is running on.
