The pixel clock determines how fast pixels can be processed. When adding
non-native common modes, avoid adding modes that exceed the max pixel
clock frequency of the native modes. Avoiding these avoids potential
mode setting failures where the GPU can't handle the modeline since the
configured pixel clock is too fast. This replaces the "bandwidth" check
which used the number of pixels and refresh rate, which wasn't enough to
avoid incompatible modes.

'screen-cast/monitor-src: Use clutter_stage_paint_to_buffer'
(6c818cd8d5) made the non-dma-buf path use
clutter_stage_paint_to_buffer() to avoid running into direct scanout
issues. At a glance, the dma-buf paths didn't have the same issue since
it explicitly handled dma-bufs by blitting them.
What it also did was move the recording to an idle callback, to avoid
paint reentry issues. A side effect of this, however, is that it also
broke the dma-buf paths, as they rely on the back buffer existing, and
the stage view direct scanout already being setup, which it isn't in an
idle callback.
Fix this by using the dma-buf variant of
clutter_stage_paint_to_buffer(): clutter_stage_paint_to_framebuffer().
This has some negative performance impact, but we can't use
cogl_blit_framebuffer() when using an idle callback for recording.
Potential performance improvements to make things work more as they did
before is to enhance 'cogl_blit_framebuffer()' a bit, making it a vfunc
that could be implemented by MetaOnscreenNative. A flag to say whether
to look at the back or front buffer would let MetaOnscreenNative know
whether to use the already committed-to-KMS buffer, or the current back
buffer.

* DMA buffer allocated using gbm on top of VKMS
* Buffer passes a mode setting TEST_ONLY check
* Paint is omitted
* Correct buffer active in KMS after presentation
What isn't yet tested:

The monitors settings such as the privacy screen property is propagated
to the monitors via kms updates, however during initialization and
on monitors changes, we end up clearing the pending KMS updates because
such settings are added to the queue before the backend has fully
initialized the monitors, and this may lead to discarding all the
pending updates, including the one we've just planned.
To avoid this, move settings applications after we've both initialized
the backend and notified it about changes.

With the unthrottled input emission, we ended up often getting the
cursor updates long before any damage had been posted, meaning that if
you moved around the mouse pointer where the mouse had a high enough

Since devices may be multiple things now, check all capabilities in order

- Devices that have TOUCHPAD | POINTER capabilities prefer the 'touchpad'

non-touchpads.
- Devices that are both a tablet and a touchscreen prefer the tablet
relocatable schema. This works for both aspects as the touchscreen

We now only enable DMA buffer based PipeWire screen casting if a

However, in case we're not hardware accelerated, we never want to
attempt to use DMA buffer screen sharing, as we want to avoid

While software based gbm devices can allocate DMA buffers, we don't want

There was a sanity check that complained if there was still a "next
framebuffer" when disposing an onscreen. This is correct to complain
about under normal operation, as we always wait until receiving the page
flip callback before cleaning up the onscreen and their state.
However, when there are many hotplugs occurring, we might end up with
race conditions when the above sanity check is not valid: when we have
more than one monitor active, paint 1 one of them, but receive a hotplug
event before we paint the other(s), we will discard the already painted
onscreen before really issuing a page flip.
In this situation, we will have the "next framebuffer", but having that
is not a bug, it's a race condition, thus to not leak in this situation,
make sure to clean up the next framebuffer here too.

When the before-paint function is executed, it's only purpose
is to check if there's any scanout queue, and immediately
record it if any.
However, since [1], we regressed in this specific case with the
introduction of an idle callback in the before-paint function.
The regression only happens when the PipeWire stream is using
DMA-BUF buffers, and it would operate as follows:
1. In before-paint, when there's a scanout available, we queue
an idle callback to capture the monitor. The idle callback
(almost always) executes after the scanout is pulled from
the stage view
2. meta_screen_cast_stream_src_maybe_record_frame() is called
by the idle callback. In the DMA-BUF case, it then runs
meta_screen_cast_monitor_stream_src_record_to_framebuffer()
3. In meta_screen_cast_monitor_stream_src_record_to_framebuffer(),
because the stage view doesn't have a scanout anymore, it
ends up calling cogl_blit_framebuffer() with the stage view
framebuffer. This is the regression bug.
This regression presents itself in the form of the screencast
stream showing the desktop when there's an unredirected fullscreen
application window running.
Revert before-paint - and only that - back to immediately capturing
any available scanout. Only record these frames when the target
buffer is a DMA-BUF handle. Nothing is captured on before-paint if
the stream is not using DMA-BUF, since the regular paint routine
will handle these frames regularly post-paint.

Next commits will reintroduce a certain behavior of stage
capturing that can only happen with DMA-BUF buffers. To
control this, add a new flag tp MetaScreenCastRecordFlags
for this behavior.

This significantly increases the chance of a fullscreen surface buffer
being scanned out instead of being painted via composition. This is
assuming the client supports the DMA buffer feedback Wayland protocol.

This API can be used to construct a MetaKmsUpdate with plane assignments
that in isolation will be tested against the current KMS state. How it
is tested depends on the KMS implementation; in the simple / legacy KMS
backend, the tests are identical to the current scanout requirements
(dimension, stride, format, modifiers, all must match), and with atomic
KMS, it uses the TEST_ONLY on a real constructed atomic mode setting

Refresh rates >60Hz become ever more common. In order to allow users
to keep hight refresh rates when not running at a natively advertized
resolution, add common refresh rates to our fallback modes.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2189>
Right now we often add a duplicate fallback mode that's almost
identical to the native mode. This adds unnecessary clutter to
UIs, thus filter out such modes.
In order to keep the code small, use `MetaCrtcModeInfo` directly
instead of recalculating the values. And to keep consistency, do
the same in the loop above.

This is so that it can unregister from it on tear down. The tracker owns
references to cursors too, but this cycle is already broken as the
backend calls 'g_object_run_dispose()' when tearing the cursor tracker
down.
Fixes a crash on shutdown.

An incorrect assumption that after mode set there would be no pending
page flips was made. This meant that if there was a mode set, followed
by a page flip, if that page flip was for a CRTC on a now unused GPU,
we'd crash due to the renderer GPU data having already been freed. This
commit avoids that by keeping it alive as long as the page flips are
still in the air. It fixes crashes with backtraces such as

This ensures we don't have any left over cursor GPU buffers (via

During tear down, if anything teared down after the seat tries to get
the cursor renderer, we'd crash trying to get it as the seat would
already be gone. Avoid this by returning NULL when there is no seat.
It's assumed that any path that will happen during tear down that relies
on getting the cursor renderer will gracefully handle it not being
present, e.g. by relying on the cursor rendering cleaning up itself.

Commit 2289f56112 ("monitor-manager: Don't apply unneeded orientation
changes") added an early return to handle_orientation_change () in case
the transform is unchanged.
But this did not take the correction of the transform for devices
with 90° mounted panels into account causing a desired orientation
change to get skipped if the new orientation matches the corrected
logical orientation from the previous transform setting.
Fix this by calling meta_monitor_crtc_to_logical_transform () on the
transform before comparing it, matching the
meta_monitor_crtc_to_logical_transform () call in
create_for_builtin_display_rotation ().

The GBM support in the NVIDIA driver is fairly new, and to make it
easier to identify whether a problem encountered is related to using GBM
instead of EGLStreams, add a debug environment variable to force using
EGLStream instead of GBM.
To force using EGLStream instead of GBM, use
MUTTER_DEBUG_FORCE_EGL_STREAM=1

Since this signal is in a hot path during input handling, it makes sense
not to have this be a signal at all, currently most of the time spent in
it is in GLib signal machinery itself.
Replace it with a function/user data pair that are set on the sprite
itself. Only the places that create an sprite are interested in hooking
one ::prepare-at behavior per sprite, so we can do with a single pair.
This makes meta_cursor_sprite_prepare_at() inexpensive enough.

Let the meta_cursor_sprite_realize() function return a boolean value
telling whether there was an actual change in the sprite cursor. E.g.
the surface/icon for it changed in between.
This is used in the native backend to avoid converting/uploading again
the cursor surface.

This is a strange thing to do since MetaInputMapper also does take care of
devices with an output configured through settings, since we might have
devices that were configure through settings exclude other devices that
belong together with an output (e.g. a display-integrated tablet).
This was essentially here as a last resort to avoid matching two very
similar looking tablets to one of two very similar looking outputs. There
was a 50% chance already that the choice was wrong, and now these devices
can all be configured specifically through settings, so this shouldn't
be missed either.

Non-display-attached tablets (e.g. Intuos) may find no match, which
should mean "use the span of all monitors", not "pick one for me".
Reserve this fallback to touchscreen devices, since these might
still benefit from it.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2107>
The matrix and aspect ratio of the tablet is irrelevant on pads, and
it actually triggers warnings when trying change that on those devices:
gnome-shell:42536): mutter-CRITICAL **: 17:22:41.994: meta_input_device_native_get_mapping_mode_in_impl: assertion 'device_type == CLUTTER_TABLET_DEVICE || device_type == CLUTTER_PEN_DEVICE || device_type == CLUTTER_ERASER_DEVICE' failed
This is unnecessary to do on pad devices, these just need to be moved
together with their respective stylus.

The cursor renderer shouldn't assume all the CRTCs of a logical are KMS
CRTC's, as we'll end up checking hardware capabilities for CRTC's of
virtual monitors as well, when they were created to not embed the cursor
image directly in the framebuffer.
Instead, use the newly introduced API for checking CRTC cursor
capabilities. This fixes a crash with the following backtrace:

On a KMS backed CRTC, hardware cursor are supported when there are
cursor planes to assign them to. Note that when using legacy mode
setting, fake cursor planes are added when adequate.
On virtual CRTCs, used with virtual monitors, the equivalent of hardware
cursor are always supported, as they are sent using embedded PipeWire
stream metadata.

It was dropping to zero after the first frame because it hadn't been
incremented high enough. So the second frame would crash with:
```
#0 g_type_check_instance_cast
#1 META_DRM_BUFFER
#2 copy_shared_framebuffer_cpu
```
That's the CPU-copy path (fallback-fallback) that probably no one is using
but it does work after this fix. Exactly the same issue as was fixed
in `copy_shared_framebuffer_primary_gpu` by 36352f44f9.

If some connectors disappeared, but the rest didn't change, we missed
actually removing the ones that disappeared, as we incorrectly assumed
nothing changed. Fix this by only assuming nothing changed if 1) we
didn't add any connector, and 2) we have the same amount of connectors
as before the hotplug event. The connector comparison checking makes
sure we report changes if anything of the still available connectors
changed.

When a docking station is disconnected, a few previously existing DRM
connectors may now be gone. When this happens, getting them via the
libdrm API results in NULL pointers returning, and we need to handle
