Ivthandleinterrupt Here

If this is a function or symbol in code (e.g., driver, kernel, or embedded systems):

Minimal pseudo-implementation (conceptual)

ivthandleinterrupt(vector, stacked_frame):
    save_cpu_state()
    if vector invalid: goto end
    irq_info = lookup(vector)
    source = detect_source(irq_info)
    handler = irq_info.handler
    if handler:
        handled = handler(stacked_frame, irq_info.dev)
        if not handled and irq_info.chained_handlers:
            try chained handlers
    if handler requested deferred_work:
        schedule_deferred_work(irq_info.work)
    send_eoi_to_controller(irq_info.controller)
end:
    restore_cpu_state()
    return_from_interrupt()
