Not sure what you're asking. We do enable the hpd interrupt for eDP
ports, but it's up to the board whether that's actually wired up
to anything. Actually yanking an eDP panel and plugging in a new
different one won't work since we cache the EDID at init time and
never re-read it. And I'm pretty sure these things aren't designed
to be hotplugged anyway, so there's probably some danger of damage
to the hardware.
