EC: Consider improving GPIO IRQ handler lookup |
|||
Issue descriptionRight now, our GPIO IRQ handlers are typically dispatched after a linear search through the available GPIO IRQ handlers in the interrupt handler. We might be able to do something more clever with the mapping. Right now, the order of the GPIO interrupts is fairly arbitrary and that order affects the latency of the handlers. It's not so bad when there are relatively few, but the problem is exacerbated as the number of handlers increases. Maybe we can do something to at least group the handlers by port.
