[PATCH] drm/i915/ddi: Avoid long delays during system suspend / eDP disabling

[PATCH] drm/i915/ddi: Avoid long delays during system suspend / eDP disabling

[Imre Deak]

Atm disabling either DP or eDP outputs can generate a spurious short
pulse interrupt. The reason is that after disabling the port the source
will stop sending a valid stream data, while the sink expects either a
valid stream or the idle pattern. Since neither of this is sent the sink
assumes (after an arbitrary delay) that the link is lost and requests
for link retraining with a short pulse.

The spurious pulse is a real problem at least for eDP panels with long
power-off / power-cycle delays: as part of disabling the output we
disable the panel power. The subsequent spurious short pulse handling
will have to turn the power back on, which means the driver has to do a
redundant wait for the power-off and power-cycle delays. During system
suspend this leads to an unnecessary delay up to ~1s on systems with
such panels as reported by Rui.

To fix this put the sink to DPMS D3 state before turning off the port.
According to the DP spec in this state the sink should not request
retraining. This is also what we do already on pre-ddi platforms.

As an alternative I also tried configuring the port to send idle pattern
- which is against BSPec - and leave the port in normal mode before
turning off the port. Neither of these resolved the problem.

D0 is the default power state IIRC, so when you plug something in it
should automagically go into D0. That's actually a slight problem
power-wise if there's no subsequent modeset to drop it into D3.

Right. The thought was about branch devices that don't wake up and
aren't disconnected/reconnected after D3. But then we don't receive HPD
for them aither.

There was this DP->VGA adaptor that seems to require that we set D0
explicitly:
https://bugs.freedesktop.org/show_bug.cgi?id=99114#c5

But it's an odd behaviour, the DPCD read itself succeeds, only reading a
certain register fails (DPCD_SINK_COUNT). Based on the DP spec a sink
should respond to AUX transfers even after being put to D3, possibly
with a longer wake-up delay (up to 20ms AFAIR).

Also [1] where AFAICT there isn't even a hotplug after D3.
