several for a MST topology change, keep polling until complete.

Beware the barbarians at the gate, who invade and steal your ScrnInfoPtr
and its Entity from underneath you. In some configurations, we lose
access to the struct intel_device stored on the Entity after
initialisation, causing havoc. Workaround this by storing the
intel_device that we open in our driverPrivate.

we need to pass along the private pointer as the flip data as we no

When using ZaphodHeads, we share the /dev/dri/card0 fd between both
screens. So when we read an event back from the fd, it could be for
either head and we cannot assume that our private pointer is valid for
the data passed along with the event. Instead, we need to retreive that
pointer from the event.

If the ddx is configured without udev support, we do not receive
notifications when the MST topology is changed. This leads us to query
the kernel for bad connectors, and so we end up reporting an unknown
connection status for them, which the user and client often find
confusing. However, we can not simply act upon the detection failure as
we are too deep inside the callback chain and cannot change the arrays of
known connectors whilst iterating over them. A neat compromise is to
hook into the rrGetInfo call chain and poll for MST changes before we
report back the current configuration.

If the Xorg does not support the ReuseNotify callback, and we use

Before we attach the Screen Pixmap to the scanout, we will have to
create a GPU bo and apply any fixups as required. Therefore failing to
pre-emptively move it during ScreenCreateResource is not fatal and the
failure can be simply ignored.

If ZaphodHeads is active, each screen only has a subset of the CRTC
assigned to it, in fact just the single CRTC associated with the pipe of
that screen. In that case, we only expect to have the single CRTC and so
should not assert that we have a list of all CRTCS.
It should still hold that we dynamically attach ZaphodHeads upon
hotplugging, so it is just the assert that is overzealous.
