The value returned from clutter_frame_get_target_presentation_time()
is always same as the value returned from
clutter_frame_get_min_render_time_allowed() when they are called
consecutively because both functions effectively return the value of
frame->has_target_presentation_time. This is with the assumption
that this variable is only ever modified by the same thread that
also executes on_after_update().
As such, a case where the former returns FALSE after the latter
returned TRUE is not possible, which means the line that sets
"target_presentation_time_us = 0;" is effectively unreachable.
Acknowledging this fact allows the call to
clutter_frame_get_target_presentation_time() to be moved outside the
"else" case and into the "if" condition itself. This is done in
preparation for the next commits.

Set the deadline timer state as "inhibited" in case a permission error

For now, this function only enables the deadline timer in case it was
inhibited. This would result in an attempt to use the deadline timer

remain, it is expected to return to this state after the next frame
and before being armed.

The "disabled" state indicates that the deadline timer is disabled

This distinction is needed to handle each state differently in a

This is the unified focus (key, IM, pads, ...) for the focus window.
Just like MetaWaylandPointer and others keep track of the "current"
surface, this is the "current" surface for those (not necessarily
the focused surface, e.g. in the case of compositor grabs).
Since this unified focus will exist regardless of keyboard
capabilities (e.g. even if just for "logical" focus like IM/clipboard
that does not depend on input devices), it does not make sense
to trigger a focus sync on keyboard capability changes, the focus
is staying the same, we however need to focus the keyboard interface
to the already existing focus when the capability is enabled.

If we happen to be changing focus to a window *while* taking focus

until the window focus changed, so that the focus change will look
up the default focused window in the workspace, and find the up to

For tablet device, the tool was created when the "Wacom Serial IDs" prop
changed values. This property does not exist on the xf86-input-libinput
driver but v1.5.0 of that driver has a different property for the serial.
The serial is constant (the driver creates one X device per serial), so
we can fetch it after device creation and set it then. For earlier
versions of the driver we assign the random serial 0xffffffaa - good
enough to have at least a tool.
This fixes the crash in #3120 - clutter_event_motion_new()
overrides event->device to the tool's device (if any). Without a tool
motion events use the Virtual Core Pointer instead and our source device
is never added to the stage's priv->pointer_devices.
When we generate an crossing event (which uses the source device) we
fall afoul of an assert in clutter_stage_update_device() that expects
our source device to be in priv->pointer_devices.

DRM's kms atomic code was updated to include an API to set the mouse
cursor hotspot. This has historically been missing in the atomic kms
which meant that the virtualized drivers which require mouse cursor
hotspot info to properly render had to be put on a deny list and
had to fallback to the legacy DRM kms code.
Implement the new hotspot API by checking whether the device supports
hotspot properties and if it does set them on the cursor plane. This
enables atomic kms on all virtualized drivers for kernels where
mouse cursor hotspots are in drm core.

Based on the pressure curve control points sample a bezier curve and

This keeps the existing ClutterBezier implementation but changes
the visible API to match the needs of the tablet tool pressure curve:
a bezier defined within a [0.0/0.0, 1.0/1.0] box,(sampled
into a set of x->y mappings for each possible pressure input x, and
a lookup function to get those values out of the curve.
This patch moves the internally-only functions to be statics and changes
meta_bezier_init() to take only the second and third control point, as
normalized doubles. Because internally we still work with integers, the
bezier curve now has an integer "precision" that defines how many points
between 0.0 and 1.0 we can sample.
The meta_bezier_rasterize() function calculates the x->y mapping for
each point on the bezier curve given the initial scale of the curve.
That value is then available to the caller via meta_bezier_lookup().

This addresses the following race condition:
1. Window+MetaFrame are created non-fullscreen, _MUTTER_FRAME_EXTENTS
is initialized through widget measuring, accounting for frame.
2. Window and MetaFrame become fullscreen.
3. MetaFrameContent gets first size allocation, already fullscreen.
4. Borders were initialized to 0,0,0,0, become set to 0,0,0,0 correctly
reflecting fullscreen, however notify::borders is not emitted.
5. _MUTTER_FRAME_EXTENTS stays accounting for the frame extents.
It sounds sensible to have the borders initialized to a meaningful value,
so account for the first time the border would be set due to the content
being (re)sized, and let this first value trigger notify::borders resulting
in _MUTTER_FRAME_EXTENTS updates.
Since all later _MUTTER_FRAME_EXTENTS changes happen through content
resizes, we only have to cater for this initial handover between the
frame/content initialization paths done through widget measuring and
the later paths done through MetaFrameContent resizes.

Finding the shm offset and shm stride for each plane is the main issue.
The rest is just creating multiple textures for each plane.
One assumption is that shm planes are always contiguous in memory so the
next plane comes directly after the size of the current plane.
The size of a plane is determined by the height and stride. There is
only a single stride parameter for shm buffers but we assume that the
first plane is always non-subsampled which gives us a number of "logical
elements" on one line (stride / bpp of the first plane). The stride of
the other planes is then the number of logical elements devided by the
subsampling factor and multiplied by the bpp of the plane.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3371>
The assumption is that all planes are always contiguous, and we don't
have any multi-plane formats where the first plane is subsampled.
The stride of the entire buffer is then just the stride of the first
plane and the stride of the other planes is derived from that.

We currently offer the mechanism for GNOME Shell to implement, and
while this is not exercised often (our entries are typically surrounded
by a ClutterGrab ensuring key events, so this is reserved to grab-less
entries, probably there are some in extensions), this is arguably
something Mutter should cover by itself without GNOME Shell guidance.
This is only necessary on the X11 backend, although it is conceptually
more tied to the MetaX11Display connection, so perform the focus
tracking there only if not running as a Wayland compositor (i.e. --x11).
This avoids the only case where the low-level
meta_x11_display_set_input_focus_xwindow() function is used, or rather
makes it completely a MetaX11Display implementation detail, leaving
only the MetaDisplay API as the high-level entry points to handle
window key focus.

When there are a set of primary planes, and a set of CRTCs, where each

This means that it doesn't necessarily mean what transform / rotation
the hardware resource gets, e.g. it instead represents the logical
transform related to the configured mode. This allows us to postpone
checking the plane capabilities until later (as rotation capabilities
depends is a plane property), when a plane has been assigned.

When we're configuring monitors, allow backends to add backend specific
assignments during resource assignment (mapping connectors and CRTCs

primary plane updates, as well as cursor updates, until reconfigured
again.

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".

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

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
management related. Eventually we'll probably want to, but that requires
bringing color management plumbing to PipeWire.
Doing this is also needed when running a headless session, as when
headless, polkit doesn't let us create colord devices without explicit
user permission, meaning we'll spam the session with useless dialogs
each time a session is started.

`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.

For scanout on a secondary GPU, for the time being try only formats
which are guaranteed to be renderable with GLES3, which notably excludes
10 bpc formats without alpha channel.

If the EGL_KHR_no_config_context extension is supported, use it to
choose a format per onscreen which is compatible with the scanout CRTC
and the GL rendering API used.
Suggested by Jonas Ådahl.
v2:
* Drop code which checked for GLES3 renderability. Makes no sense for
various reasons, in particular that EGLconfigs are about EGLSurfaces,
whereas secondary GPU contexts use an FBO for blitting.

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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3406>
Track where we are in terms of the paint cycle. Do this through an
enumeration that is passed through the paint vfuncs of screencast
sources.
Right now, this information is not used by any one of the sources,
but next patch will use it to prevent blitting when detached from
the paint cycle.

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.

The window actor can be mapped every frame, e.g. when it is dragged in
the overview. This commit keeps track when the geometry changed and we
didn't managed to sync the geometry yet and need to sync it at a later
time.

At the end of the sync_actor_geometry function the window buffer_rect
and the WindowActor position and size are the same and consistent.
Call the virtual method at the end and let the implementations look at
either the buffer_rect or the actor position/size itself.

In some cases the window is not mapped when the geometry changes.
Without the mapped window the surfaces are not mapped either and don't
have a sensible allocation.
This patch makes sure we abort syncing the geometry if the window is not
mapped and also make sure we sync geometry when the actor eventually
does get mapped.

Scoped traces are less error prone, and they can still be ended
prematurely if needed (this commit makes that work). The only case this
doesn't support is starting a trace inside a scope but ending outside,
but this is pretty unusual, plus we have anchored traces for a limited
variation of that.

Sticky keys configuration changes reset the pressed modifier state mask,
even though the XKB state might already match with the expected new
state. In those cases we can avoid the XKB state mask update completely.
This also fixes a crash at initialization with sticky keys toggled on,
since configuring the device a11y settings will trigger a XKB state
mask merely reassuring the initial state with no modifiers pressed,
while the connection between the ClutterSeat and the impl object has
not been set up yet. This crash was introduced by commit 00bb4190b

meta_display_ping_window() does nothing when check-alive-timeout is set
to 0, but meta_window_check_alive_on_event() was relying on it to reset
the events_during_ping. Without this events_during_ping was just
counting up until the threshold was reached and the window was marked as
not alive, preventing further pointer events from being sent to the
window.
Fix this by not doing anything in meta_window_check_alive_on_event() if
check-alive-timeout is 0, similar to meta_display_ping_window().

specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
