Changing the MultiTexture may require a different set of pipelines when
the texture format is different. We keep track of the attached
MultiTextureFormat just like we do for the width and height.

Most tests use the draw_surface function to draw a solid color to a

When capturing the view we have to make sure the stage is actually
updated. In direct scanout mode the stage is unmodified and we can't
find the content we want to test.
Currently the ref-tests are all running on non-native setups where
direct scanout is impossible but we will change that soon!
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3350>
Transfer none was achieved using a stack GArray in the stage which
would get resized to 0 at the end of every frame to "free" it.
In the case of direct scanout however, painting the next frame only
happens after leaving fullscreen again. Until then the array just kept
growing and because GArrays don't reallocate when shrunk, this memory
remained allocated even after leaving fullscreen.
There is no cache benefit from storing paint volumes this way, because
nothing accesses them after their immediate use in the calling code.
Also the reduced overhead from avoiding malloc calls seems negligible as
according to heaptrack this only makes up about 2-3% of the temporary
allocations.
Changing this to transfer full and removing the stack array simplifies
the code and fixes the "leak".

This is a step in cleaning up the Clutter context management. By making
it a GObject it's easier to add e.g. properties and features that helps
with introspection.
For now, this means the context creation is changed to go via a
"constructor" (clutter_create_context()). This is so that the global
context singleton can be mantained outsid of ClutterContext, until it
can be removed.

Since meta_kms_impl_device_get_sync_file always returns the same

the Wayland surface state.

When a stream is destroyed by a consumer, mutter won't be able to
recognize that.
For mutter, the stream just paused, but did not disconnect, because the
connection state of a PipeWire stream only represents, whether the
respective PipeWire context is connected to PipeWire.
In addition to that, it may be the case, that the stream consumer just
recreates the stream.
So even if mutter would be able to know, when the stream consumer
destroyed a stream, but not the whole screencast or remote-desktop
session, then mutter would not know, whether the stream will be resumed
eventually or not.
So, add an explicit API call to the screencast interface to stop a
stream.
For virtual streams, this also means, that the respective virtual
monitor is destroyed.

When a virtual stream is destroyed, its respective virtual monitor is
destroyed too. When the virtual monitor is destroyed, mutter reloads
the monitor manager.
However, at this point, the virtual stream is not completely destroyed
yet. The viewport of the virtual monitor still exists at this point and
when the monitor manager reloads, it will try to fetch the logical
monitor of the now destroyed virtual monitor, which will fail and thus
gnome-shell will run into a segfault.
Fix this situation by reloading the monitor manager in an idle callback.
When the monitor manager reloads, the virtual monitor is completely
gone, since the viewport of the virtual monitor is destroyed after the
virtual monitor itself.

There is no way to set any gamma luts, or do anything other color

`count_mode_setting_devices` was incorrect in both name and in function.
What it was actually doing was counting GPUs that had been registered with
the backend so far (during the `init_gpus` loop). What it was intended to
do was to count the number of `MetaRenderDeviceEglStream` instances, which
is the thing we're limited to only one of. So `count_mode_setting_devices`
would return zero whenever the first GPU initialized happened to be a
`MetaRenderDeviceEglStream`, which would in turn prevent
`MetaRenderDeviceEglStream` from successfully initializing. Seems it only
ever worked in the case of a hybrid system where the first GPU initialized
was GBM-based.
Now we count `MetaRenderDeviceEglStream` instances (zero or one) externally.
This allows initialization to succeed when it happens to be the first (or
only) GPU. And so `MUTTER_DEBUG_FORCE_EGL_STREAM=1` now works.

In profilers with a timeline or flame graph views it is a very common
scenario that a span name must be displayed in an area too short to fit
it. In this case, profilers may implement automatic shortening to show
the most important part of the span name in the available area. This
makes it easier to tell what's going on without having to zoom all the
way in.
The current trace span names in Mutter don't really follow any system
and cannot really be shortened automatically.
The Tracy profiler shortens with C++ in mind. Consider an example C++
name:
SomeNamespace::SomeClass::some_method(args)
The method name is the most important part, and the arguments with the
class name will be cut if necessary in the order of importance.
This logic makes sence for other languages too, like Rust. I can see it
being implemented in other profilers like Sysprof, since it's generally
useful.
Hence, this commit adjusts our trace names to look like C++ and arrange
the parts of the name in the respective order of importance.

Now that the monitor screencast records to DMA-BUF buffers immediately
(since bc2f1145d8), and we know which phase of the paint rountines we
are (since last commit), we have the opportunity to bring back the
blitting technique.
Bring back blitting. This time, instead of simply failing if the blit
fails, add a fallback path that does a stage paint if something goes
wrong. Unlike the previous implementation of blitting, this one only
blits the current view - it does not blit all views that intersect
with the screencasted monitor.
Embedded cursors should still be fine because hardware cursor is
inhibited while embedded cursor screencasts are running.

Track where we are in terms of the paint cycle. Do this through an

With the existing ClutterInputMode terminology (inherited from XI2),
hardware devices may be "physical" (i.e. attached to a logical device),
or "floating" (i.e. detached from all logical devices).
In the native backend, tablet devices are closer to "floating" than
"physical", since they do not emit events relative to the ClutterSeat
pointer logical device, nor drive the MetaCursorTracker sprite. This
is in contrast to X11 where all tablet devices drive the Virtual
Core Pointer by default, along with every other pointing device.
Change this mode in the Wayland backend to be more coherent. The
existing checks on the ClutterInputMode along Mutter seem appropriate
for handling these as floating devices, since they mainly care about
logical vs non-logical.

There are existing extensions that implement desktop icons as
a combination of a GTK program and a small extension to make
the wayland window behave as if it was of type DESKTOP on X11.
That's quite painful, as it requires reimplementing WM behavior
that is already implemented in mutter itself (stacking, stickiness,
skip-taskbar, ...), as well as modifying gnome-shell to consider
the window in addition to "real" DESKTOP windows (workspace-switch
animations, ctrl-alt-tab, ...).
In addition to that, other extensions may also have special handling
of DESKTOP windows, and their code cannot easily be monkey-patched
to handle "alternative" desktop icons.

When running headless, only the invalid modifiers are advertised.
That breaks with the NVIDIA proprietary driver which then rejects the
buffers created with the invalid modifier, and that kills Xwayland,
meaning that running Xwayland on top of a mutter based compositor
headless is not possible.
The reason the modifiers are not sent is because AddFb2 is not supported
when running headless.
Other compositors (weston, wlroots) would still send the modifiers even
without AddFb2, and Xwayland works fine on those compositors when
running headless.
Remove the requirement for AddFb2 to send the modifiers, so that
Xwayland can work fine on top of mutter headless with the NVIDIA
proprietary driver.

`clutter_actor_destroy()` queues a stage update. Under certain
circumstances - i.e. when run in a very slow container - this can race
with the stage update triggered by the following
`clutter_virtual_input_device_notify_button()`, occasionally resulting in
`wait_stage_updated()` to return before the
`on_event_return_propagate()` callbacks ran, making the test fail.
This notably became more common since
8f27ebf87e (clutter/frame-clock: Start next update ASAP after idle period)
landed.
Thus wait for a stage update to happen after `clutter_actor_destroy()`,
preventing the race.

Certain kernel drivers can take an unreasonably long time to
complete mode setting operations. That excessive CPU time is charged
to the process's rlimits which can lead to the process getting killed
if the thread is a real-time thread.
This commit inhibits real-time scheduling around mode setting
commits, since those commits are the ones currently presenting as
excessively slow.

At the moment if a thread is made real-time there's no going back,
it stays real-time for the duration of its life.
That's suboptimal because real-time threads are expected by RTKit to
have an rlimit on their CPU time and certain GPU drivers in the kernel
can exceed that CPU time during certain operations like DPMS off.
This commit adds two new ref counted functions:
meta_thread_{un,}inhibit_realtime_in_impl
that allow turning a thread real-time or normally scheduled. At the same
time, this commit stores the RTKit proxy as private data on the thread
so that it can be reused by the above apis.
A subsequent commit will use the new APIs.

If we queued a mode set, but didn't end up compositing all frames, we'll
have pending mode sets in a hash table waiting to be applied. If we
before all monitors again try to reconfigure things we should drop the
old pending mode sets and start fresh.
We already do this when we're doing so when generating views, but when
just unsetting modes, we didn't, so fix that.

We had a function called "reset_modes()" on MetaRendererNative, but what
it expected to do was to unset all modes on all CRTCs. Despite this, it
had code to unset modes on unconfigured CRTCs, probably because it was
used for multiple things in the past.
Make this a bit easier to follow by renaming the function
"unset_modes()" and fold the function doing the unsetting into the
function itself.

Intel has started to advertise big gamma LUT sizes on some hardware
because the hardware supports segmented LUTs. This means they have a lot
more precision at certain segments then others. The uAPI can't expose
this functionality meaningfully so they chose to expose a huge number of
TAPs to sample from to their segmented LUT.
This increase in uAPI LUT size resulted in stack overflows because we
allocated the LUT on the stack. This commit moves it to the heap
instead.

1. Centralize stride calculation in one function.
2. For dmabufs query the stride instead of assuming a certain value.
3. For system memory buffers use the pixel format to calculate the
stride.
4. Stop negotiating `SPA_PARAM_BUFFERS_size` and
`SPA_PARAM_BUFFERS_stride`.
2. fixes an actual bug where we reported wrong max buffer sizes,
resulting in crashes in Gstreamer when doing area screencasts on AMD
GPUs.
The reasoning for 4. is that the values were possibly wrong for
dmabufs as the negotiation happens before we create any buffers.
Further more neither Mutter nor the common consumers required it.
The later either ignore the values (OBS), always accept (gstpipewiresrc)
them or calculate the exact same possibly wrong values (libwebrtc).

With EI support wired to XTEST, and oeffis being enabled in Xwayland
means that XTEST will always go through the XDG portal.
While this the intended behavior for the general use case of Xwayland
running rootless on a desktop compositor, that breaks when Xwayland is
running on a nested compositor, because the portal is for the entire
session and not limited to the nested Wayland compositor.
Enable XDG portal support in Xwayland only when we managed to connect
to the GNOME session manager, which means we are running in a full
desktop session, and not in any form of nested mode.
This is determined by simply using the status returned by set_gnome_env()
which will fail if not connected to a GNOME Session manager.

The function set_gnome_env() is used to pass environment variables

When a configuration has a fractional scale, but we're using a physical
monitor layout, we can't use the scale, but if we do, we end up with
wierd issues down the line. Just discard the config if we run into this.
Eventually we probably want to store the layout mode in the
configuration so we can handle more seamless switching between physical
and logical layout mode, but first do this.

The surface actors may not have a valid allocation when running the

in that case, can be wrong in certain cases, making us not add the black

There's two aspects from its documentation
(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
affecting us here:
1. "This function is similar to xkb_state_key_get_syms(), but intended for
users which cannot or do not want to handle the case where multiple
keysyms are returned (in which case this function is preferred)."
We are indeed in that field, and have been for a long time.
2. "This function performs Capitalization Keysym Transformations."
This is unlike the xkb_key_get_syms() function that we use, and
convenient here for parity with X11 since it behaves exactly that
way.
Fixes cases where the keysym for some keys is not properly capitalized
when caps lock is toggled, due to the output of capslock+key being
different from shift+key. An example of this is 'é' in french(azerty)
layout (bound to the '2' key). Even though shift+2 outputs '2',
capslock+é should output 'É'.

This is similar, but reserved for the crossing events induced by the
input shape changes on our overlay window. The mechanism in the previous
commit does again protect against this, so this mechanism may go away.

Focus follows mouse is meant to avoid focusing windows that happened
to pop up under the pointer, e.g. due to mapping, workspace changes,
etc... On X11, this has been done since ancient times through a
moderately complex synchronization mechanism, so mutter would know
to ignore crossing events caused on those situations.
This mechanism is much prior to XInput 2 though, where we may know
this in a more straightforward way: If the sourceid of the crossing
event is a logical pointer (i.e. equals deviceid), the crossing event
was triggered logically, and not through user input.
Perform this simpler check, and drop the existing mechanism to
ignore logically induced crossing events.

The virtual stream source with CURSOR_MODE_EMBEDDED uses
META_STAGE_WATCH_AFTER_PAINT as the callback for recording its frame. In
this stage of the paint though, there is no ClutterPaintContext anymore
(there only is a paint context during the paint, not afterwards).
The callback (actors_painted()) tries to get the redraw clip from the paint
context, and we end up with a NULL pointer crash.
We actually do still have a redraw clip at this point, so because everyone
uses the paint context to get the redraw clip anyway, just pass the redraw
clip to the stage watches directly.

After an event has been handled such that it bypasses both Clutter and
Wayland, e.g. when handling a keybinding, bypass_clutter would get
unset in the presence of a wayland grab. This means that the event is
handled both as a keybinding and by Clutter.
In the case of switcher popups in gnome-shell in the presence of a gtk4
autohide popover this meant that instead of selecting the next element,
it would select the one after that. If there are only two elements, as
is common with input sources, this would mean going back to the current
one, preventing switching them with a single press of the keybinding.

When a device is added, libei does not allow adding additional regions
for that particular device, as it is already advertised to the EI
client.
As a result, mutter currently effectively only adds the first region to
a device, but not the others.
This makes input in multi monitor sessions only possible on one monitor,
as the EI client cannot look up the other regions, since they were not
advertised to it.
Fix this situation by not adding and resuming the device, when a shared
device is used.
Instead, for shared devices, always add all regions first, and then
after that, add and resume the device.

Use the previously added API to release acquired mapping ids, when the
corresponding stream is destroyed.
Otherwise, the remote desktop session would maintain a whole bunch of
unused mapping ids, as their corresponding streams are already
destroyed, but maybe not the session.
Such situation would be a remote multimonitor session, where the amount
of used virtual monitors changes multiple times during the session.

Avoid passing the MetaSeatImpl, since it may be potentially null at
MetaSeatNative construction time. An example of this triggering issues
are mousekeys, since those work on an emulated pointer device created
indirectly after a keyboard device is added (and the right settings are
enabled) at a time that the MetaSeatImpl is still being created, so the
MetaSeatNative cannot yet have a reference to it.

These objects already have a pointer to the ClutterSeat that has a
pointer to the MetaSeatImpl in its native implementation. This data
may be considered pretty much immutable (a pointer to the seat is
held, and the native implementation will shut down the implementation
thread within ClutterSeat finalization.
Avoids some awkward code, since the MetaInputDeviceNative needs to
be aware of the Clutter object implementation and the implementation
object.

vc4's implementation of `drmModeAtomicCommit` seems to require a few

That's too high for our deadline evasion threshold which is measured

It's the 10 bit equivalent to NV12 and uses the same layout as P016, i.e.
16 bit components with the lowest 6 bits set to 0 (padding), allowing us
to use 16 bit "subformats".
Thus adding support is quite trivial as we can reuse the NV12 shader.
The format is widely supported in decoding and display hardware (on Intel
since Kaby Lake), as well as modern codecs (AV1, VP9, HEVC) and has
visible quality advantages over NV12.
Note that the additional colors are lost if composited to a 8 bit RGB
framebuffer. Switching between direct scanout and compositing can thus
cause quality differences. This is no new phenomena, however, as the
same is the case already for e.g. GL clients using 10 bit formats -
including video players.
Also note that P012 and P016 could trivially added as well - it's not
done here as they are uncommen and thus hard to test.

These shaders can be used for similar formats with other component
sizes since the values are represented as floats. So whether the source
value was stored in 8bit, 10bit or 16bit doesn't matter - the driver
will covert it for us.
Thus use a Weston-inspired, more general naming scheme.
