XWayland clients get their opaque region set from their window, not the
surface. Doing both resulted in the surface constantly overwriting the
opaque region - effectively disabling culling of XWayland clients.

Devices have capabilities that other parts need to know about. Instead
of having them probe using drmMode* API, outsource this to
MetaKmsDevice. Currently the only capability tracked is HW cursor size.

Turns the cursor setting and movement into cursor plane assignment
primitives. In the current simple implementation, this in turn

A cursor plane can now be assigned, and for the simple KMS
implementation, it'll translate into drmModeSetCursor() and
drmModeMoveCursor() calls.
When assignments failed, the cursor planes that failed to be assigned
are communicated via the feedback object.

The frame bounds as returned by `meta_window_actor_get_frame_bounds()`
would be used as cropping values when streaming a window content.
But, as its name implies, it returns the actual frame bounds, whereas we
may want to include the whole buffer, to include client side shadows for
example.
Rename the `get_frame_bounds()` API to `get_buffer_bounds()` (which was
previously partly removed with commit 11bd84789) and return the actual
buffer bounds to use as the cropping area when streaming a window.

The clip bounds passed in `meta_window_actor_capture_into()` represent
the actual allocated buffer size where the window actor image will be
eventually copied.
As such, it is completely agnostic to the scaling factors that might
affect the different surface actors which compose the window actor.
So instead of trying to compute the scale factor by which the given
clipping bounds need to be adjusted, simply clip the resulting image
based on the given bounds to make sure we never overflow the destination
buffer.

The actors of Wayland subsurfaces are set to be reactive on creation,
when receiving the `wl_subcompositor.get_subsurface` request.
However, if a client creates several subsurfaces and then creates the
xdg_toplevel object after, the previous subsurface actors are reset.
As a result, Clutter picking will skip and ignore those actors in
`clutter_actor_should_pick_paint()` because they aren't marked as
reactive anymore.
An example of such a client being affected by this issue is SCTK, the
Rust library implementing client side decorations for Wayland used
internally by winit and alacritty.
Move the `set_reactive()` call from `get_subsurface()` to the subsurface
`sync_actor_subsurface_state()` vfunc to make sure those remain reactive
even after `xdg_surface.get_toplevel` is invoked.

Modify create_for_builtin_display_rotation to lookup the
MetaLogicalMonitorConfig for the panel in the logical_monitor_configs
list instead of only working when there is only 1 monitor.
The goal of this change is to honor accelerometer value changes when there is
more than 1 monitor.
Note, since create_for_builtin_display_rotation is also used for handling the
"rotate-monitor" hotkey and this commit modifies the common path of
create_for_builtin_display_rotation this means that we will now also honor
"rotate-monitor" hotkey keypresses when there is more than 1 monitor and
update the builtin display rotation instead of ignoring "rotate-monitor"
hotkey keypresses when there is more than 1 monitor. If this is deemed
undesirable this is easy to fix, but I believe that doing things this way
is more consistent.

When creating a new config because of a monitor being (un)plugged or
because of super+p being pressed, honor the orientation reported by
the accelerometer for the internal panel.
Before this commit we would always configure the internal panel with
a normal / upright transform when e.g. an external monitor gets plugged
in even if another transform was in use before plugging in the external
monitor. This is inconsistent and causes problems for several use-cases.
This commit fixes this by querying the accelerometer when creating a new
config for an internal panel.

Bail out of sync_state() immediately if the orientation is locked, before
calling read_iio_prox() which updates the curr_orientation value.
There are 2 reasons for this change:
1. Currently meta-monitor-config-manager.c always assumes normal / upright
orientation when generating a new config. This means that e.g. when an
external monitor gets plugged in the builtin panel's transform will be reset
to normal / upright even if the device is not in an upright orientation.
To fix this meta-monitor-config-manager.c needs to call
meta_orientation_manager_get_orientation() to get the current orientation
when generating a new config. Without this change locking the orientation
would stop the emitting of "orientation-changed" signals but we would
still update the curr_orientation value. So when a new config needs to
be generated the latest orientation would be used, effectively ignoring
the "orientation-lock" setting, not updating curr_orientation when
locked fixes this.
2. This ensures we properly emit an an "orientation-changed" signal when
the orientation has changed between when it was locked and it was
unlocked. Before this change if the user locked the orientation, changed it
and then unlocked it, no signal would be raised as we would already have
updated the curr_orientation value turning the sync_state() call in
orientation_lock_changed() into a no-op.

Using `-Dnative_backend=false` caused build failure due to a missing
(implicit) definition of `META_IS_BACKEND_X11`. But if we define it

native backend to initialize the variables.

Scaling the `monitor_area` before texture creation was just wasting
megabytes of memory on resolution that the monitor can't display. This
was also hurting runtime performance.
Example:
Monitor is natively 1920x1080 and scale set to 3.
Before: The monitor texture allocated was 5760x3250x4 = 74.6 MB
After: The monitor texture allocated is 1920x1080x4 = 8.3 MB

When creating a virtual device for the native backend, no "device-added"
is emitted.
Similarly, no "device-removed" signal is emitted either when the virtual
device is disposed.
However, the backend plugs into the "device-added" signal to set the
monitor device. Without the "device-added" signal being emitted, the
monitor associated with a virtual device remains NULL.
That later will cause a crash in `meta_idle_monitor_reset_idlettime()`
called from `handle_idletime_for_event()` when processing events from a
virtual device because the device monitor is NULL.
Make sure to emit the "device-added" signal when creating a virtual
device, and the "device-removed" when the virtual device is disposed.

When an X11 window requests an initial workspace, we currently trust
it that the workspace actually exists. However dynamic workspaces
make this easy to get wrong for applications: They make it likely
for the number of workspaces to change between application starts,
and if the app blindly applies its saved state on startup, it will
trigger an assertion.
Make sure that we pass valid parameters to set_workspace_state(),
and simply let the workspace assignment fall through to the default
handling otherwise.

Most usually, applications either expose clipboard content either as text
or as images, so the prioritization here is pointless. However there's some

image based ones.

The meta_seat_native_constrain_pointer() function receives the current

We were however calculating the new coordinates based on the last pointer

When a Wayland window is mapped or unmapped, the Wayland compositor is
expected to send the coorespoindign `wl_pointer` enter/leave events to
the affected clients.
To do so, mutter calls `meta_wayland_compositor_repick()` which
eventually calls `meta_wayland_pointer_repick()` and
`repick_for_event()`.
If pointer input device has not been updated yet, the old clutter actor
is picked and no enter/leave event is emitted.
Make sure we update the pointer input device prior to do the repick to
get the actual `ClutterActor` under the pointer.

When building the frame mask, the current reported frame size may not

Currently, `meta_frame_get_mask()` and `meta_ui_frame_get_mask()` will

With Xwayland, the shape region is recomputed and reapplied even when

Where possible, try to export the buffer rendered by the primary GPU as a
dmabuf and import it to the secondary GPU and turn it into a DRM FB for
scanout. If this works, we get a zero-copy path to secondary GPU outputs.
This is especially useful on virtual drivers like EVDI (used for DisplayLink
devices) which are not picky at all about what kind of FBs they can handle.
The zero-copy path is prioritised after the secondary GPU copy path, which
should avoid regressions for existing working systems. Attempting zero-copy
would have the risk of being less performant than doing the copy on the
secondary GPU. This does not affect the DisplayLink use case, because there is
no GPU in a DisplayLink device.
The zero-copy path is prioritised before the primary GPU and CPU copy paths. It
will be tried on the first frame of an output and the copy path is executed
too. If zero-copy fails, the result from the copy path will take over on that
frame. Furthermore, zero-copy will not be attemped again on that output. If
zero-copy succeeds, the copy path is de-initialized.
Zero-copy is assumed to be always preferable over the primary GPU and CPU copy
paths. Whether this is universally true remains to be seen.
This patch has one unhandled failure mode: if zero-copy path first succeeds and
then fails later, there is no fallback and the output is left frozen or black.

With all the three paths this is quite a handful of code, and it was mostly
duplicated in two places. A follow-up patch would need to introduce a third
copy of it. Therefore move the code into a helper function.
There are two behavioral changes:
- The format error now prints the string code as well, because it is easy to

There will be another place where I need to release the dumb buffers but not
destroy the whole secondary_gpu_state, so extract this bit of code into a

The checks of fb_id are dropped as redundant with the check already in in
release_dumb_fb ().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
release_dumb_fb () checks 'map' to see if anything needs freeing. Other places
are checking fb_id instead. The checks maybe redundant, but let's reset all
fields here while at it, so that all the checks work as expected.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
Simplify the bo freeing functions by not checking what the copy mode is. This
matches what swap_secondary_drm_fb () already does. g_clear_object () is safe
to call even if the value is already NULL.
The copy mode does not change mid-operation. If it did, this change would
ensure we still clean up everything. So this is more future-proof too.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
To mirror what happens in meta_onscreen_native_swap_buffers_with_damage(), warn
here too if next_fb is not NULL. This makes it clear to the reader of what the
expectations are inside this function.
Ensuring next_fb is NULL as the first thing in the function will make all error
paths equal: no longer some failures reset next_fb while others don't. Removing
such special cases should reduce surprises.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
If we end up trying to do a mode set on a DRM state that has already
changed behind our back without us yet having seen the hotplug event we
may fail with `EINVAL`. Since the renderer layer doesn't handle mode set
failure, it'll still try to page flip later on, which will then also
fail. When failing, it'll try to look up the cached mode set in order to
retry the mode set later on, as is needed to handle other error
conditions. However, if the mode set prior to the page flip failed, we
won't cache the mode set, and the page flip error handling code will get
confused.
Instead of asserting that a page flip always has a valid cached mode set
ready to look up, handle it being missing more gracefully by failing to
mode set. It is expected that things will correct themself as there
should be a hotplug event waiting around the the corner, to reconfigure
the monitor configuration setting new modes.

On Xwayland, freezing actor updates on sync requests means the
server-side frame and shadows repaint will be frozen as well, which
causes the shadow to show black at times when resizing X11 clients
which support NET_WM_SYNC.
Using freeze/thaw commits prevents the content from changing, yet the
shape window still needs to be updated when frozen otherwise the
difference in shape induced by the on-going resize operation will show

To address the black shadows that sometimes show during resize with
Xwayland, we need to update the window shape regardless of the frozen
status of the window actor.
However, plain Xorg does not need this, as resized windows do not clear
to black, so add a new vfunc to window/x11 to indicate whether or not
the backing windowing system (either plain X11 or Xwayland) would
require the shape to be always updated.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/942
Currently, the window actor freeze/thaw implementation sets the frozen
state of the surface actor using `meta_surface_actor_set_frozen()`.
If we want to expand that behavior to also freeze/thaw commits for X11

that in the window actor specific implementation.

To be able to thaw commits following a resize that might have frozen

Xwayland may post damages for an X11 window as soon as the frame
callback is triggered, while the X11 window manager/compositor has not
yet finished updating the windows.
If Xwayland becomes compliant enough to not permit updates after the
buffer has been committed (see [1]), then the partial redraw of the X11
window at the time it was posted will show on screen.
To avoid that issue, the X11 window manager can use the X11 property
`_XWAYLAND_ALLOW_COMMITS` to control when Xwayland should be allowed to
post the pending damages.
Add `freeze_commits()` and `thaw_commits()` methods to `MetaWindowX11`
which are a no-op on plain X11, but sets `_XWAYLAND_ALLOW_COMMITS` on
the toplevel X11 windows running on Xwayland.

At the moment we only disarm the watchdog timer set up for SYNC counter
requests if we're in the middle of a resize operation.
It's possible that the resize operation finished prematurely by the user
letting go of the mouse before the client responded. If that happens, when the
client finally updates mutter will erroneously still have the watchdog timer
engaged from before until it times out, leading to resizes for the next second
or so to not get processed, and the client to get blacklisted from future sync
requests.

This avoids using bogus geometric values from an unmapped actor to

Without 'wayland/surface-actor: Reset and sync subsurface state when
resetting' this test would fail.
This also adds a simple framework for testing lower level Wayland
semantics.
In contrast to the test-client and test-driver framework, which uses
gtk and tests mostly window management related things, this framework is
aimed to run Wayland clients made to test a particular protocol flow,
thus will likely consist of manual lower level Wayland mechanics.
A private protocol is added in order to help out clients do things they
cannot do by themself. The protocol currently only consists of a request
meant to be used for getting a callback when the actor of a given
surface is eventually destroyed. This is different from the wl_surface
being destroyed due to window destroy animations taking an arbitrary
amount of time. It'll be used by the first test added in the next
commit.

As with most other state that ends up being pushed to the actor and the
associated shaped texture, also push the texture and the corresponding
metadata from the actor surface. This fixes an issue when a toplevel
surface was reset, where before the subsurface content was not properly
re-initialized, as content state synchronization only happened on
commit, not when asked to synchronize.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/961
A actor surface may be reset by an xdg_toplevel if a NULL buffer is
attached. This should reset the actor state of the toplevel to an empty
state, while unmapping the previous actor. Subsurfaces, however, should
stay intact, including their relationship to the toplevel. They should
also not be yanked away from the actor of the actor surface prior to it
resetting, so that a window-destroy animation can include the subsurface
actor.
This fixes a potential crash when a subsurface tries to commit to its
wl_surface after the destroy animation of the toplevel has finished, as
the actor would at that point have been destroyed and cleared from the
actor surface struct, causing a segmentation fault.

Similar to wl_list_foreach(), add

While it's not very relevant now, as we would rarely create it anyway
since the buffer nor texture never changes for a surface, it will be in
the future, as the actor state (including its content,
MetaShapedTexture) will be synchronized by the MetaWaylandActorSurface
at a later point in time, and not by MetaWaylandSurface, at state
application time.

The method `relative_motion_across_outputs` is used to adjust the
distance/delta of a mouse movement across multiple monitors to take the
different scale factors of those monitors into account. This works by
getting the adjacent monitors that the movement-line/vector intersects
with and adjusting the final position (or end point of the
movement-line) by multiplying the parts of the line spanning across
different monitors with the scale factors of those monitors.
In the end of this calculation, we always want to set the new end
coordinates of the relative motion to the new end coordinates of the
adjusted movement-line. We currently only do that if all adjacent
monitors the line is crossing actually exist, because only then we end
up inside the "We reached the dest logical monitor" else-block and set
`x` and `y` to the correct values. Fix that and make sure the returned
values are also correct in case an adjacent monitor doesn't exist by
adding separate `target_x` and `target_y` variables which we update during
each pass of the while loop so we're always prepared for the while loop
exiting before the destination monitor was found.
Thanks to Axel Kittenberger for reporting the initial bug and tracking
the issue down to `relative_motion_across_outputs`.

Therefore, use a scale of 1 for the non-
experimental case.
Patch is based on commit 3fa6a92cc5.

'xwayland: Do not queue frame callbacks unconditionally' changed the
frame callback behavior of Xwayland surfaces so that they behave the
same way as other actor surfaces (e.g. xdg-shell ones), except for the
case when they are initially assigned.
Remove this special casing as well including the now incorrect comment,
so that the Xwayland surfaces behave the same as the others in this
regard also when assigning.

The vfunc is not called when a surface commits its state, but when the
state is applied. Make this clearer by changing the name to
"apply_state" (and "pre_apply_state").

This changes how asynchronous window configuration works. Prior to this
commit, it worked by MetaWindowWayland remembering the last
configuration it sent, then when the Wayland client got back to it, it
tried to figure out whether it was a acknowledgment of the configuration
or not, and finish the move. This failed if the client had acknowledged
a configuration older than the last one sent, and it had hacks to
somewhat deal with wl_shell's lack of configuration serial numbers.
This commits scraps that and makes the MetaWindowWayland take ownership
of sent configurations, including generating serial numbers. The
wl_shell implementation is changed to emulate serial numbers (assuming
each commit acknowledges the last sent configure event). Each
configuration sent to the client is kept around until the client one. At
this point, the position used for that particular configuration is used
when applying the acknowledged state, meaning cases where we have
already sent a new configuration when the client acknowledges a previous
one, we'll still use the correct position for the window.

In Wayland, window configuration is asynchronous. Window geometry is
constrained, the constrained geometry is sent to the client, and the
client will adapt its surface and acknowledge the configuration. When
acknowledged, we shouldn't reconstrain again, as that may invalidate the
constraint calculated for the configured size.

Historically, wl_shell clients used to pretend the input region was
equivalent to the window geometry, so for "correctness" lets do that
here too. This makes wl_shell clients with drop shadow behave marginally
better than before.

This moves the cached subsurface surface state into the generic
MetaWaylandSurface namespace. Eventually it'll be used by other surface
roles which as well aim to implement synhcronization.

The name didn't communicate it was about surface state, and it somewhat
confusingly had the name "pending" in it, which could be confused with
the fact that while it's used to collect pending state, it's also used
to cache previously committed pending state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
With the eventual aim of exposing the internals of MetaWaylandSurface
outside of meta-wayland-surface.c, make users of the pending state use a
helper to fetch it. While at it, rename the struct field to something
more descriptive.
