I've killed them a long time ago in drm/i915, let's get rid of this
remnant of shared drm core days for good.

So GNOME userspace has an issue with when it rescans for modes on hotplug
events, if the monitor has no EDID it assumes that nothing has changed on
EDID as with real hw we'd never have new modes without a new EDID, and they
kind off rely on the behaviour now, however with virtual GPUs we would
like to rescan the modes and get a new preferred mode on hotplug events
to handle dynamic guest resizing (where you resize the host window and the
guest resizes with it).
This is a simple property we can make userspace watch for to trigger new
behaviour based on it, and can be used to replaced EDID hacks in virtual
drivers.

All drivers embed gem-objects into their own buffer objects. There is no
reason to keep drm_gem_object_alloc(), gem->driver_private and
->gem_init_object() anymore.
New drivers are highly encouraged to do the same. There is no benefit in
allocating gem-objects separately.

These two helpers are unused. Remove them. They rely on
gem_obj->driver_private, which is set to NULL during setup. As this field
isn't used by the driver, anymore, we can remove this assignment as well.

All the gem based kms drivers really want the same function to
destroy a dumb framebuffer backing storage object.
So give it to them and roll it out in all drivers.
This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.

The recent addition of lockdep support to reservations and their subsequent
use by TTM showed up a number of potential problems with the way qxl was using
TTM objects.
a) it was allocating objects, and reserving them later without validating
underneath the reservation, which meant in extreme conditions the objects could
be evicted before the reservation ever used them.
b) it was reserving objects straight after allocating them, but with no
ability to back off should the reservations fail. It now allocates the necessary
objects then does a complete reservation pass on them to avoid deadlocks.
c) it had two lists per release tracking objects, unnecessary complicating
the reservation process.
This patch removes the dual object tracking, adds reservations ticket support
to the release and fence object handling. It then ports the internal fb
drawing code and the userspace facing ioctl to use the new interfaces properly,
along with cleanup up the error path handling in some codepaths.

Due to the nature of qxl hw we cannot queue operations while in an irq
context, so we queue these operations as best we can until atomic allocations
fail, and dequeue them later in a work queue.
Daniel looked over the locking on the list and agrees it should be sufficent.
The atomic allocs use no warn, as the last thing we want if we haven't memory
to allocate space for a printk in an irq context is more printks.

This adds suspend/resume and hibernate support for the KMS driver. it evicts
all the objects, turns off the outputs, and waits for the hw to go idle,
On resume, it resets the memslots, rings, monitors object and forces modeset.

this splits out initing the hw memslots from the guest info, and

This adds support for a default of 4 heads, with a command line
parameter to change the default number.
It also overhauls the modesetting code to handle this case properly,
and send the correct things to the hardware at the right time.

QXL is a paravirtual graphics device used by the Spice virtual desktop
interface.
The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
is quite different than normal TTM expects, we have to keep track of a number
of non-linear fence ids per bo that we need to have released by the hardware.
The releases are freed from a workqueue that wakes up and processes the
release ring.
releases are suballocated from a BO, there are 3 release categories, drawables,
surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.
The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface
ids.
This requires a newer version of the QXL userspace driver, so shouldn't be
enabled until that has been placed into your distro of choice.
