NAME
trace_irq_handler_exit - called immediately after the irq action handler returnsSYNOPSIS
- void trace_irq_handler_exit(int irq, struct irqaction * action, int ret);
ARGUMENTS
irq
- irq number
action
- pointer to struct irqaction
ret
- return value
DESCRIPTION
If the ret value is set to IRQ_HANDLED, then we know that the corresponding action->handler scuccessully handled this irq. Otherwise, the irq might be a shared irq line, or the irq was not handled successfully. Can be used in conjunction with the irq_handler_entry to understand irq handler latencies.
