how does bochs emulate all those interrupts?

[ITchimp]

My understanding of basic architecture of bochs is to set aside a large block of memory
and interpret the instruction one after another .... what I want to know is how to emulate interrupts, like clock signal, keyboard etc?

Every so often, take a break from interpreting instructions to see if an interrupt should happen.

Like Octocontrabass said, but it is checked after each and every instruction. The main cpu loop is here, and the "interrupt pending" internal flags are checked in event.cc (where each interrupt source is hardwired in the code, like "is_pending(BX_EVENT_PENDING_LAPIC_INTR)" or "is_unmasked_event_pending(BX_EVENT_SMI)").

Use the source, Luke
