Hi intel-gfx folks.
This issue is coming up for me again. Can anyone comment on where I can go
for an answer?

Sorry, bad patch email.
Working on it...

The only additional information I have is that the irq occurs on a regular
6.47s interval.
Can anyone comment on the mechanism?

The i915 driver normally assumes the video bios has configured several
of the LVDS panel registers, and it just inherits the values. If the
vbios has not run, several of these will need to be setup.
intel_bios.c: default clock source selection on pineview to use the SSC
source

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_
who knows what else.

I have a situation where unplugging an external monitor and running an
xrandr sequence to return the screen to the internal display sometimes
causes the i915 driver to wig out.
In perusing the intel-gfx archives, I see
http://lists.freedesktop.org/archives/intel-gfx/2010-May/006957.html makes a

I will accept a redirect to another list if this is the wrong one.
When I run a loop of "xset dpms force off; sleep 1; xset dpms force on;
sleep 1" to repeatedly turn on and off the panel (connected through i915
LVDS), it does not come back on after a while. The backlight comes on, but
the frameb
