I have a pineview system with VGA output that takes anywhere from 1 to 5
seconds to detect an external monitor plug in/out, and I am trying to reduce
that latency. But I do not know how hotplug detection works.
My first sign of detection is in i915_driver_irq_handler() where we
read PORT_HOTPLUG_

Hi all-
