This uses the queue that was introduced when migrating impl task
management from MetaThread to MetaThreadImpl, with the exception that
it's now fully used as an actual queue. It now has a GSource that sits
on the right GMainContext that is dispatched whenever there are tasks to
execute.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2777>
It's the impl side that wants to add impl side idle sources, or fd
sources, etc, so make it part of MetaThreadImpl.
This changes things to be GAsyncQueue based. While things are still
technically single threaded, the GAsyncQueue type is used as later we'll
introduce queuing tasks asynchronously, then eventually queuing across
thread barriers.

It currently does exactly what MetaKms and MetaKmsImpl did regarding the
context separation, which is to isolate what may eventually run on a KMS
thread into a separate unit. It works somewhat like a "user thread",
i.e. not a real thread, but will eventually learn how to spawn a
"kernel thread", but provide the same API from the outside.

Remote desktop version 2 added a new method ConnectToEIS .
ConnectToEIS allows clients to requests a file descriptor from the
compositor which can then be used directly from libei.
Once established, the communication between compositor and application
is direct, without the need to go through the portal process(es).

This adds the actual input capturing rerouting that takes events and
first hands them to the input capture session, would it be active.
Events are right now not actually processed in any way, but will
eventually be passed to a libei client using libeis.
A key binding for allowing cancelling the capture session is added
(defaults to <Super><Shift>Escape) to avoid getting stuck in case the client
doesn't even terminate the session.
The added test case makes sure that the pointer moves again after
pressing the keybinding.

When a relative pointer motion gets constrained (e.g. a monitor edge or
barrier), save the constrained relative motion delta too.
This will later be used to send the remaining motion delta to input
capture clients.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
Adding a barrier and later enabling the input capture session will
create MetaBarrier instances for each added input capture barrier.
The barriers are created as "sticky" which means that when a pointer
hits the barrier, it'll stick to the point of entry, until it's
released.
The input capture session is also turned into a state machine with
explicit state, to more easily track things.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
This allows for a sticky barrier to hold the pointer until it is
released, but the owner of the barrier doesn't need a barrier event to
release it. It will be used to implement input capturing.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
A sticky barrier means that a pointer in motion intersecting a barrier
doesn't move once having hit it. The intention with this is to allow an
input capture clients to continue a motion once a barrier is hit.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
This API aims to provide a way for users to capture input devices under
certain conditions, for example when a pointer crosses a specified
barrier.
So far only part of the API is implemented, specifially the session
management as well as zone advertisement, where a zone refers to a
region in the compositor which edges will eventually be made available
for barrier placement.
So far the remote access handle is created while the session is enable,
despite the input capturing isn't actually active yet. This will change
in the future once it can actually become active.

Previously, restarting mutter in an X11 session resulted in
the previously set color temperature not being applied.
Fix that by applying the color temperature right after
the org.gnome.SettingsDaemon.Color proxy has been created.
Furthermore, only call `update_all_gamma()` from `on_gsd_color_ready()`
when the temperature has actually changed. Otherwise there is no need
since the current temperature has already been (or will soon be) applied
to all ready color devices.

In remote desktop sessions, streams can be created and destroyed
on-the-fly.
If a stream is gone, it is not necessarily an error.
So, don't treat that situation like an erroneous one.

The previous logic didn't work correctly at least when priority-based
preeption wasn't supported by the DRM driver, such as in the case
of amdgpu. The call to glGetQueryObjecti64v would block on client
work which is already in progress (most likely for the next frame)
and delay notifying the ClutterFrameClock about presentation.
Conveniently, the Wayland transactions mechanism guarantees that all
fences of a dma-buf buffer are signalled before the buffer is
included in a frame, which means that dma-buf buffers are ready for
presentation when being directly scanned-out.
Direct scanout is only supported for dma-buf buffers too, which means
that all buffers going through direct scanout are effectively ready
and require no GPU rendering before presentation.
Assuming zero rendering time for dma-buf buffers going through direct
scanout simplifies the code and removes the need for
glGetQueryObjecti64v, thus avoiding the aforementioned issue where it
could block for longer than expected.

This means initializing the pointer position in MetaSeatImpl
synchronously too, otherwise it's not guaranteed querying the seat state
will result in the expected position.

I have a monitor which can report two preferred modes: 5120x1440@240
and 3840x1080@60. Since they are enumerated in this order by KMS,
init_output_modes would end up using 3840x1080@60 (and it was impossible
to select any 5120x1440 mode in the GNOME display settings).
Fix this by using meta_kms_connector_get_preferred_mode, which returns
the first KMS mode with DRM_MODE_TYPE_PREFERRED.
v2:
* Use meta_kms_connector_get_preferred_mode. (Jonas Ådahl)

This will consist of device-added events, meaning before init finishes,
we can derive some state that depends on the set of input devices
available on startup, such as cursor visibility.
This avoids cursor visibility switching between hidden and visibility
during startup.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3070>
This opens up for a possibility to handle initial events (devices
discovered on startup) during initialization, meaning we can figure out
a more correct initial state that depends on available input devices.

This is different from "warping" as it doesn't necessarily result in a
pointer motion event. This can be helpful during initializing so we can
avoid faked pointer events that would otherwise need to be special cased
to not appear as actual pointer movements.

We currently lock the capability of the MetaOrientationManager to emit
the ::orientation-changed signal, but otherwise keep reading the current
orientation and returning it if we are asked politely through
meta_orientation_manager_get_orientation().
This may bring issues e.g. around suspend/resume, since there may be other
parts of the code trying to get the current orientation without receiving
::orientation-changed signals, this may result in the display orientation
being effectively rotated, then stay locked after that.
In order to fix this, make the MetaOrientationManager return a fixed
orientation while locked, only updated after changes in the lock state.

This is missed, leaving the cursor renderer disconnected from the stage
updates that could trigger further frame callbacks on the cursor, leaving
some clients like Xwayland stuck with cursors.

We do in fact allow these combinations of configuration since the Settings
Wacom panel revamp. We no longer need to look up Wacom device features,
since this is allowed for all the devices that have these settings.

We avoided setting the device matrix applying to the tablet tool (used if the
tablet is in absolute coordinates mode) if the device is configured for relative
motion, but forgot to apply the matrix if changing the device back to absolute
mode, this made the device seemingly forget its attached display until later
configuration changes.
In order to avoid the hassle of looking up the right display again on unrelated
configuration changes, make the matrix be always set on the device, but only
actually used in absolute coordinates mode. This makes the device able to
seamlessly switch between modes and remain mapped to the right display.

This was somewhat ineffective since it was applied after figuring out
the x/y absolute coordinates. Change the order (filter first, then
figure out abs coords), and use coordinates from the correct device
while at it.
