While doing this, rename the old synchronous functions to more clearly
communicate that they expect to actually process the update during the

While the default when passing NULL will be the main context of the main
thread, make it possible to specify another main context, so that
result handlers can be invoked on the right thread.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2777>
Callbacks could be queued to be invoked either on the impl side or the
main thread side of the thread; change this to take a GMainContext,
which effectively means a callback can be queued to be invoked on any
thread that has a GMainLoop running on its own GMainContext.
Flushing is made to handle flushing callbacks synchronously on all
threads. This works by keeping a hash table of queued callbacks per
thread (GMainContext); when flushing (from the main thread), callbacks
on the main thread context is flushed, followed by synchronization with
all the other threads.
meta_thread_flush_callbacks() is changed to no longer return the number
of dispatched callbacks; it becomes much harder when there are N queues
spread across multiple threads. Since it wasn't used for anything, just
drop the counting, making life slightly easier.
Feedback to thread tasks are however always queued on the callers
thread.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2777>
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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2777>
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).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
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

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.

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.

This will consist of device-added events, meaning before init finishes,

This is different from "warping" as it doesn't necessarily result in a

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.

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.

While it's obviously good to trap possible errors from X calls, we are
mixing the Clutter error trap with the MetaX11Display one for these
calls.
This may result in situations where a X call within a Clutter error
trap fails, but it's actually handled in these sections using the
MetaX11Display error trap. This one will consider the serial out
of the "handled" parts and raise an error.

the type of the ClutterInputDevice object's "meta-input-settings-xdevice"

considers it to be an `XDevice`, so everything that uses the return

Otherwise drivers would be free to alter the buffer content. While no

The DMA buffer paths vs MemFd paths differ slightly in when content is
recorded. This was in some places done by trying to record but bail if
the dequeued buffer had the wrong type. This is problematic for two
reasons: we'd update the timestamp even if we refused to record, making
the follow-up attempt fail, and we'd dequeue and queue buffers that
didn't get any content, meaning the receiving end would see empty
buffers potentially with only cursor updates.
Fix this by keeping track if a stream is DMA buffer able or not, and
don't attempt to record at all in the places we would previously require
DMA buffers. This avoids both issues: we don't dequeue/queue pw_buffers
that we refuse to record to, and we won't update the recorded timestamp
when we didn't intend to record to begin with.

We might get told to restore the old monitor configuration by the

happen during frame clock dispatch. If we would restore an old

meta_monitor_manager_confirm_configuration (meta-monitor-manager.c:2880)
meta_plugin_complete_display_change (meta-plugin.c:172)

The color space and HDR metadata are eventually sent as metadata to the

The only color spaces we support right now are the default color space
and Rec bt.2020 which is typically used for HDR content. Other supported
color spaces can be added when needed.
The default color space corresponds to whatever colorimetry the display
has when no further changes are made to the calibration of the display.

the colord CdIcc object, so it will be freed when the g_autoptr unrefs
the CdIcc, and we must not free it again: that would be a double-free,
potentially resulting in memory corruption.

We want to avoid using too high scales too easily, which started to
happen 2f1dd049bf ("monitor-manager: Rework default scale factor
selection"). Instead of using the closest non-fractional scale, which
effectively is what we'd do, only round upwards if we're closer than
0.25 (25%).
Since there are some wiggle room for scales to make the logical
resolution on the integer pixel grid, make sure to compensate. This
compensation is done by adding an extra 0.2 to scale difference.
For example the following fractional scales will get these corresponding
integer scales:
* 1.25 -> 1.0
* 1.5 -> 1.0
* 1.75 -> 2.0
* 2.0 -> 2.0
* 2.50 -> 2.0

Instead of testing headless start using the dummy backend, do so with
the real native backend, and use the drm-mock library instead to emulate
monitors being disconnected at startup.

As part of https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/525
(introduction of transactional KMS API), the logic determining whether a
GPU can have outputs was changed from whether any connectors existed to
whether any connected connectors existed. That effectively meant that we
wouldn't attempt to start at all if there were no monitors connected
while starting up.
This was unintentional, so lets revert back the expected behavior.

In order to make things more and more asynchronus and to each time we
paint be an isolated event, that can be potentially be applied
individually or together with other updates, make it so that each time
we draw, we use the transient MetaFrameNative (ClutterFrame) instance to
carry a KMS update for us.
For this to work, we also need to restructure how we apply mode sets.
Previously we'd amend the same KMS update each frame during mode set,
then after the last CRTC was composited, we'd apply the update that
contained updates for all CRTC.
Now each CRTC has its own KMS update, and instead we put them in a per
device table, and whenever we finished painting, we'll merge the new
update into any existing one, and then finally once all CRTCs have been
composited, we'll apply an update that contains all the mode sets for all
relevant CRTCs on a device.

MetaRendererViewNative is a MetaRendererView which contains logic
specific to views of the native backend. It will be used by following
commits.
In the future, per-view logic from MetaRendererNative can be moved to
MetaRendererViewNative where it makes more sense to have it.

Instead of using the "discarded" page flip callback when the
"discarding" happened during actual immediate processing, communicate
the same via the KMS update feedback.
The "discarded" page flip callback is instead used only for when a
posted page flip is discarded. In the atomic backend, this only happens
on shutdown, while in the simple backend, this also happens when a
asynchronous retry sequence eventually is abandoned.
This allows further improvements making KMS handling fully async.

At first it was called seal(), but then updates could be amended after
being posted, given a flag. That flag has been removed, so we can go
back to sealing, since it's once again acts more as a seal.

We test direct client buffer scanout using a TEST_ONLY commit on atomic,
and with various conditions in non-atomic, but if we end up failing to
actually commit despite this, handle the fallout asynchronously. What
this means is that we'll reschedule a new frame immediately.
For this to work, the same scanout buffer needs to be avoided for the
same CRTC. This is done by using the newly added signal on the
CoglScanout object to let the MetaWaylandBuffer object mark the current
buffer as non-working for the onsrceen that it failed on. This allows to
re-try buffers on the same onscreen when new ones are attached.
This queues a full damage, since we consumed the qeued redraw rect. The
redraw rect wasn't lost - it was accumulated to make sure the whole
primary plane was redrawed according to the damage region, whenever we
would end up no longer doing direct scanout, but this accumulation only
works when we're not intentionally stopping to scanout. For now, lets
just damage the whole view, it's just an graceful fallback in response
to an unexpected error anyway.

If we get a "ready" page flip feedback, it means the page flip was
symbolic, i.e. not real, e.g. as a result of an update that didn't
change the state of the primary plane. Warn if there is a "next fb"
meaning we expected to have a new buffer that we flipped to.

This is intended to be used only for plane assignment, and CRTC like
changes, so that one can e.g. change a cursor plane on a pending update
that changes the primary plane, before it has been committed to KMS.
The kms-updates test overrides the get-state function MetaKmsCrtc. This
is needd to not have the update mechanism not clamp the gamma size to 0,
as vkms reports the gamma length 0. By pretending it's 3, we can test a
simple and small gamma lut is merged correctly when merging updates.

Screen-casted windows need to be considered visible in various situations
but existing APIs such as `clutter_actor_is_effectively_on_stage_view()`
don't do so. Add new API that allows checking if a surface belongs to a
screen-casted window for the respective cases.

From the scale factors available to it, Mutter will now try to select
the scale factor that makes the UI's size as close as possible to the
size it would be, w/o scaling, on a display at 135 PPI (for mobile
displays) or at 110 PPI (for stationary displays)

The pointer to the manager, the peer name and the ID are things that are
always metadata related to a session, so make them properties on the
interface instead of duplicating them. The implementations still need to
keep track of them, but their existance is shared.
