This patch address the following underlying issues with SurfaceDMA
* SurfaceDMA command does not work in a 2D VM, but we can wrap a
proxy surface around the same DMA buffer and use the SurfaceCopy
command which does work in a 2D VM.
* Wrapping a DMA buffer with a proxy surface also gives us an
added optimization path for the case when the DMA buf
dimensions match the mode. In this case, the DMA buf can
be pinned as the display surface, saving an extra copy.
This only works in a 2D VM because we won't be doing any
rendering operations directly to the display surface.

Now that we also grab the connection_mutex and so fixed the race with
atomic modeset we can use the iterator there too.
The other special case is drm_connector_unplug_all which would have a
locking inversion with the sysfs store/show functions if we'd grab the
mode_config.mutex around the unplug. We could just grab
connection_mutex instead, but that's a bit too much a dirty trick for
my taste. Also it's only used by udl, which doesn't do any other kind
of connector hotplugging, so should be race-free. Hence just stick

While auditing various users of the connector/encoder lists I realized
that the atomic code is a very prolific user of them. And it only ever
grabs the mode_config->connection_mutex, but not the
mode_config->mutex like all the other code walking encoder/connector
lists.
The problem is that we can't grab the mode_config.mutex late in atomic
code since that would lead to locking inversions. And we don't want to
grab it unconditionally like the legacy set_config modeset path since
that would render all the fine-grained locking moot.
Instead just grab more locks in the dp mst hotplug code. Note that
drm_connector_init (which is the one adding the connector to these
lists) already uses drm_modeset_lock_all.
The other reason for grabbing all locks is that the dpms off in the
unplug function amounts to a modeset, so better to take all required
locks for that.

Because of DP MST connectors can now be hotplugged and we must hold

checking the locking in our shiny new list walking macros.
v2: Extract the locking check into a small static inline helper to
help readability. This will be more important when we make the
read list access rules more complicated in later patches. Inspired by
comments from Chris. Unfortunately, due to header loops around the
definition of struct drm_device the function interface is a bit funny.
v3: Encoders aren't hotadded/removed. For each dp mst encoder we
statically create one fake encoder per pipe so that we can support as

This is now truly only duct-tape to keep locking checks happy since
calling this function when hpd or polling are already enabled is a
bug. The fbdev helper can't cope with hotplug changes yet at this
point, only after that.
Otoh a bit more robustness in this function can't hurt, and with this
fbdev can actually cope with hotplug changes. And it's also more
consistent with the connector hotadd/remove dp mst needs to do.
Therefore document this as new official behavior.

So on first looks this seems superflous since drivers should ensure
correct ordering to not make this a problem. Otoh ordering constraints
between hdp, fbdev load and enabling polling are already tricky on
some hardware and it helps to be more robust.
But the real goal is to just shut up a locking WARN_ON I'd like to
add, which means init code gets some additional locks just for
uniformity.

which is used for resume, with the same justification.

Most of the functionality of DQM is shared between CI and VI. Therefore,
only a handful of functions are required to be in the
H/W-specific part of DQM.

This patch implements all the VI MQD manager functions.
This is done in a different file as the MQD format is different
between CI and VI
