When destroying a window that has a parent, we initially try to focus one of
its ancestors. However if no ancestor can be focused, then we should instead
focus the default focus window instead of trying to request focus for a window
that can't get focus anyways.

On FreeBSD, gethostname is guarded by '__POSIX_VISIBLE >= 200112', which
requires either '_POSIX_C_SOURCE >= 200112' or '_XOPEN_SOURCE >= 600'.
Defining _XOPEN_SOURCE to 500 does not break the build because of
implicit declaration, but it defeats the purpose of defining the macro.

We get a signed integer (-1 meaning "no workspace specified"), store it in
an unsigned integer, check for >= 0 (of course it is!) and set as the window
workspace (signed integer, -1 meaning "show on all workspaces"). What could

This commit introduces, and makes use of, a transactional API used for
setting up KMS state, later to be applied, potentially atomically. From
an API point of view, so is always the case, but in the current
implementation, it still uses legacy drmMode* API to apply the state
non-atomically.
The API consists of various buliding blocks:
* MetaKmsUpdate - a set of configuration changes, the higher level
handle for handing over configuration to the impl backend. It's used to
set mode, assign framebuffers to planes, queue page flips and set
connector properties.
* MetaKmsPlaneAssignment - the assignment of a framebuffer to a plane.
Currently used to map a framebuffer to the primary plane of a CRTC. In
the legacy KMS implementation, the plane assignment is used to derive
the framebuffer used for mode setting and page flipping.
This also means various high level changes:
State, excluding configuring the cursor plane and creating/destroying
DRM framebuffer handles, are applied in the end of a clutter frame, in
one go. From an API point of view, this is done atomically, but as
mentioned, only the non-atomic implementation exists so far.
From MetaRendererNative's point of view, a page flip now initially
always succeeds; the handling of EBUSY errors are done asynchronously in
the MetaKmsImpl backend (still by retrying at refresh rate, but
postponing flip callbacks instead of manipulating the frame clock).
Handling of falling back to mode setting instead of page flipping is
notified after the fact by a more precise page flip feedback API.
EGLStream based page flipping relies on the impl backend not being
atomic, as the page flipping is done in the EGLStream backend (e.g.
nvidia driver). It uses a 'custom' page flip queueing method, keeping
the EGLStream logic inside meta-renderer-native.c.
Page flip handling is moved to meta-kms-impl-device.c from
meta-gpu-kms.c. It goes via an extra idle callback before reaching
meta-renderer-native.c to make sure callbacks are invoked outside of the
impl context.
While dummy power save page flipping is kept in meta-renderer-native.c, the
EBUSY handling is moved to meta-kms-impl-simple.c. Instead of freezing the
frame clock, actual page flip callbacks are postponed until all EBUSY retries
have either succeeded or failed due to some other error than EBUSY. This
effectively inhibits new frames to be drawn, meaning we won't stall waiting on
the file descriptor for pending page flips.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
The MetaKmsImpl implementation may need to add a GSource that should be
invoked in the right context; e.g. a idle callback, timeout etc. It
cannot just add it itself, since it's the responsibility of MetaKms to
determine what is the impl context and what is the main context, so add
API to MetaKms to ensure the callback is invoked correctly.
It's the responsibility of the caller to eventually remove and destroy
the GSource.

As with CRTC state, variable connector state is now fetched via the
MetaKmsConnector. The existance of a connector state is equivalent of
the connector being connected. MetaOutputKms is changed to fetch
variable connector state via MetaKmsConnector intsead of KMS directly.
The drmModeConnector is still used for constructing the MetaOutputKms to
find properties used for applying configuration.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Move reading state into a struct for MetaCrtcKms to use instead of
querying KMS itself. The state is fetched in the impl context, but
consists of only simple data types, so is made accessible publicly. As
of this, MetaCrtcKms construction does not involve any manual KMS
interaction outside of the MetaKms abstraction.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Represents drmModeConnector; both connected and disconnected. Currently
only provides non-changing meta data. MetaOutputKms is changed to use
MetaKmsConnector to get basic metadata, but variable metadata, those
changing depending on what is connected (e.g. physical dimension, EDID,
etc), are still manually retrieved by MetaOutputKms.

A plane is one of three possible: primary, overlay and cursor. Each
plane can have various properties, such as possible rotations, formats
etc. Each plane can also be used with a set of CRTCs.
A primary plane is the "backdrop" of a CRTC, i.e. the primary output for
the composited frame that covers the whole CRTC. In general, mutter
composites to a stage view frame onto a framebuffer that is then put on
the primary plane.
An overlay plane is a rectangular area that can be displayed on top of
the primary plane. Eventually it will be used to place non-fullscreen
surfaces, potentially avoiding stage redraws.
A cursor plane is a plane placed on top of all the other planes, usually
used to put the mouse cursor sprite.
Initially, we only fetch the rotation properties, and we so far
blacklist all rotations except ones that ends up with the same
dimensions as with no rotations. This is because non-180° rotations
doesn't work yet due to incorrect buffer modifiers. To make it possible
to use non-180° rotations, changes necessary include among other things
finding compatible modifiers using atomic modesetting. Until then,
simply blacklist the ones we know doesn't work.

Add MetaKmsCrtc to represent a CRTC on the associated device. Change
MetaCrtcKms to use the ones discovered by the KMS abstraction. It still
reads the resources handed over by MetaGpuKms, but eventually it will
use only MetaKmsCrtc.
MetaKmsCrtc is a type of object that is usable both from an impl task
and from outside. All the API exposed via the non-private header is
expected to be accessible from outside of the meta-kms namespace.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
The intention with KMS abstraction is to hide away accessing the drm
functions behind an API that allows us to have different kind of KMS
implementations, including legacy non-atomic and atomic. The intention
is also that the code interacting with the drm device should be able to
be run in a different thread than the main thread. This means that we
need to make sure that all drm*() API usage must only occur from within
tasks that eventually can be run in the dedicated thread.
The idea here is that MetaKms provides a outward facing API other places
of mutter can use (e.g. MetaGpuKms and friends), while MetaKmsImpl is
an internal implementation that only gets interacted with via "tasks"
posted via the MetaKms object. These tasks will in the future
potentially be run on the dedicated KMS thread. Initially, we don't
create any new threads.
Likewise, MetaKmsDevice is a outward facing representation of a KMS
device, while MetaKmsImplDevice is the corresponding implementation,
which only runs from within the MetaKmsImpl tasks.
This commit only moves opening and closing the device to this new API,
while leaking the fd outside of the impl enclosure, effectively making
the isolation for drm*() calls pointless. This, however, is necessary to
allow gradual porting of drm interaction, and eventually the file
descriptor in MetaGpuKms will be removed. For now, it's harmless, since
everything still run in the main thread.

MetaStageWatch, watch modes and the watch function are part

Currently the EGLDevice code gets the display and calls eglInitialize.
As a follow-up it checks the required EGL extensions - technically it
could check the EGL device extensions earlier.
In either case, eglTerminate is missing. Thus the connection to the
display was still bound.
This was highlighted with Mesa commit d6edccee8da ("egl: add
EGL_platform_device support") + amdgpu.
In that case, since the eglTerminate is missing, we end up reusing the
underlying amdgpu_device due to some caching in libdrm_amdgpu. The
latter in itself being a good solution since it allows buffer sharing
across primary and render node of the same device.
Note: we should really get this in branches all the way back to 3.30.

As per commit 7718e67f, destroying the compositor causes destroying window
actors and this leads to stack changes, but at this point the stack was already

has already been destroyed.
As consequence, also the stamps should be destroyed at later point.

To emulate X11 grabs, mutter as a Wayland compositor would disable its
own keyboard shortcuts and when the X11 window is an override redirect
window (which never receives focus), it also forces keyboard focus onto
that X11 O-R window so that all keyboard events are routed to the
window, just like an X11 server would.
But that's a bit of a “all-or-nothing” approach which prevents
applications that would legitimately grab the keyboard under X11 (like
virtual machine viewers) to work by default.
Change “xwayland-allow-grabs” to control whether the keyboard focus
should be locked onto override redirect windows in case of an X11 grab.
For stringent needs, careful users can still use the blacklisting
feature (i.e. a list containing “!*”) to prevent grabs from any X11
applications to affect other Wayland native applications.

bits here. We can only honor this on applications that request focus
on a surface after a startup request, as we do need an explicit
surface to apply the workspace on (and we don't have additional clues
like WMCLASS on X11). Notably, gtk_shell1.notify_startup doesn't suffice.
Another gotcha is that the .request_focus happens when the surface is
already "mapped". Due to the way x11 and the GDK api currently work (first
reply on the startup id, then map a window, then request focus on that
window). This means the surface will ignore at this point
window->initial_workspace, so it must be actively changed.

On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.

Since commit 956ab4bd made libcanberra mandatory, we never use

This argument instructs Xwayland to exit when there are no further
client connections. However we eventually want to handle restarts
ourselves (where, notably, mutter's will be at least the last client
connection).
This behavior could also induce race conditions on startup with clients
that quickly open and close a display, which is a more pressing issue.
Also, add -noreset back (which was also removed in commit 054c25f693 that
added -terminate). We don't want to reset the X server to a pristine state
in that situation either.

It is now separated into meta_xwayland_start(), which picks an unused
display and sets up the sockets, and meta_xwayland_init_xserver(), which
does the actual exec of Xwayland and MetaX11Display initialization.
This differentiation will be useful when Mutter is able to launch Xwayland
lazily, currently the former calls into the latter.

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

We use a GtkIconTheme (thus icon-theme, thus xsettings, thus x11) just to
grab a "missing icon" icon to show in place. Relax this requirement that
surfaces for icon/mini-icon will be set, and just let it have NULL here.
It seems better to have the callers (presumably UI layers) aware of this
and set a proper icon by themselves, but AFAICS there is none in sight,
not even plain mutter seems to use MetaWindow::[mini-]icon. Probably
worth a future cleanup.

If the check happens on --nested (X11 backend) while there is no X11

This explicit ungrab is made to ensure the other X11 display connection
is able to start an active grab immediately on the device without receiving
AlreadyGrabbed.
This is just relevant if there's two X11 display connections to transfer

This object takes care of the X11 representation of the window stack,
namely the _NET_CLIENT_LIST and _NET_CLIENT_LIST_STACKING root window

This code has been lifted from src/core/stack.c into src/x11 as it's
dependent on the X11 display availability. This also leaves MetaStack
squeaky clean of x11 specifics.

We'd break the loop for moving attached windows at the first window,
meaning we'd only ever move a single attached dialogs or popup if it was
the first window in the list. This doesn't work out well when there are
multiple popups open, so don't break out of the loop at all until all
windows are potentially moved.
This fixes an issue in gtk4 where one or more non-grabbing popups would
end up unattached if there were more than one and the parent window was
moved.

XkbNewKeyboardNotify informs the client that there is a new keyboard
driving the VCK. It is essentially meant to notify that the keyboard
possibly has a different range of HW keycodes and/or a different
geometry.
But the translation of those keycodes remain the same, and we don't
do range checks or geometry checks (beyond using KEY_GRAVE as "key
under Esc", but that is hardly one). It seems we can avoid the
busywork that is releasing all our passive grabs, reloading the keymap
and regenerating the keycombos and restoring the passive grabs.

There is no reason why we should have an internal type enum when we have

In order to scale a rectangle by a double value, we can reuse a ClutterRect

All child classes of `MetaWaylandShellSurface` as well as
`MetaWaylandSurfaceRoleXWayland` should only sync their actor if
their toplevel surface has a window. Currently this check is done
in the actor-surface class, but not all surface classes have a
toplevel window, e.g. dnd-surfaces.
Move the check to the right places.
For subsurfaces this assumes that the subsurface is not the child of
a window-less surface (like, as stated above, e.g. a dnd-surface).
If we want to support subsurfaces of window-less surfaces in the future
we have to extend the check here.
But as this is not a regression, ignore this case for now.

If we update the ready time while the source is already in the

the source will still be dispatched. This could cause incorrect idle

Fix this by not actually dispatching the idle timeout if the ready time

This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.
This is not quite a X11 clipboard manager, but also works there.

This object represents a Wayland selection owner. In order to invert the

This object represents the selection ownership from an X11 client. The
list of supported targets is queried upfront, so its initialization is
asynchronous. Requests to read contents from the selection will hand

MetaSelectionSource represents a primary/clipboard/dnd selection owner,
it is an abstract type so wayland/x11/etc implementations can be provided.
These 3 selections are managed by the MetaSelection object, the current
selection owners will be set there, and signals will be emitted so the
previous selection owner can clean itself up.
The actual data transfer is done through the meta_selection_transfer_async()
call, which will take a GOutputStream and create a corresponding
GInputStream from the MetaSelectionSource in order to splice them.

When the compositor is destroyed we should cleanup the list of window actors we
created and destroy them.
Since all the actors are added to the window_group or top_window_group we can
just destroy these containers (together with the feedback_group), and simply
free the windows list.
This is particularly needed under X11 because before we destroy the display, we
might do some cleanups as detaching the surface pixmaps and freeing the damages
and if this happens at later point (for example when triggered by garbage
collector in gnome-shell), we might crash because the x11 dpy reference is
already gone.
Destroying the window actors instead, ensures we avoid any further call to X11
related functions and that we release the actors XServer resources.

When an application stops responding, the shell darkens its windows.
If a window from a not-responding application gets unmanaged
then the shell will currently throw an exception trying to retrieve

up before the actor is disocciated from its window.

When focus stealing prevention kicks in, mutter would set the demand
attention flag on the window.
Focus stealing prevention would also prevent the window from being
raised and focused, which is expected as its precisely its purpose.
Yet, when that occurs, the user expects the window which has just been
prevented from being focused to be the next one in the MRU list, so
that pressing [Alt]-[Tab] would raise and give focus to that window.
This works fine when the window is placed on the primary monitor, but
not when placed on another monitor, in which case the window which has
been denied focus is placed ahead of the MRU list and pressing
[Alt]-[Tab] would leave the focus on the current window.
This is because of a mechanism in `meta_display_get_tab_list()` which
forces the windows with the demand attention flag set to be placed first
in the MRU list when they're placed on a workspace different from the
current one.
But because workspaces apply only to the primary monitor (by default),
the windows placed on other outputs have their workspace set to `NULL`
which forces them ahead of the MRU list by mistake.
Fix this by using the appropriate `meta_window_located_on_workspace()
function to check if the window is on another workspace.

Since "renderer/native: make EGL initialization failure not fatal" it is
possible, under specific failure conditions, to end up with a primary GPU whose
EGL initialization failed. That cannot work.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/521
The failure to initialize EGL does not necessarily mean the KMS device cannot
be used. The device could still be used as a "secondary GPU" with the CPU copy
mode.
If meta_renderer_native_create_renderer_gpu_data () fails,
meta_renderer_native_get_gpu_data () will return NULL, which may cause crashes.
This patch removes most of the failures, but does not fix the NULL dereferences
that will still happen if creating gpu data fails.
This patch reorders create_renderer_gpu_data_gbm () so that it fails hard only
if GBM device cannot be created, and otherwise always returns an initialized
gpu data structure. Users of the gpu data structure are responsible for
checking egl_display validity.
The GBM device creation failure is a hard failure because presumably GBM is
necessary for cursors.

We're currently always waiting for unfinished page flips before flipping
again. This is awkward when we are in an asynchronous retry-page-flip
loop, as we can synchronously wait for any KMS page flip event.
To avoid ending up with such situations, just freeze the frame clock
while we're retrying, then thaw it when we succeded.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
We rely on the frame clock to compress input events, thus if the frame
clock stops, input events are not dispatched. At the same time, there
is no reason to redraw at a full frame rate, as nothing will be
presented anyway, so slow down to 10Hz (compared to the most common
60Hz). Note that we'll only actually reach 10Hz if there is an active
animation being displayed, which won't happen e.g. if there is a screen
shield in the way.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
When we're in a page-flip retry loop due to the FIFO being full
(drmModePageFlip() failing with EBUSY), we should not continue to try
when starting to power save, as that means we're blocking new frames,
which itself blocks input events due to them being compressed using the
frame clock.
We'd also hit an assert assuming we only try to page flip when not power
saving.
Thus, fake we flipped if we ended up reaching a power saving state while
retrying.

DPMS is configured from a bit all over the place: via D-Bus, via X11 and

Commit 8e9184b6 added filtering to avoid image jaggies when downscaling
but used `LINEAR_MIPMAP_NEAREST`. In some situations this could lead to
GL choosing a single lower resolution mipmap and then upscaling it, hence
slightly blurry.
We don't want to revert that change since it avoids aliasing jaggies, so
let's use `LINEAR_MIPMAP_LINEAR` instead. This provides the highest quality
filtering that GL can do and avoids the situation of GL using a single
mipmap that's lower resolution than the screen. Now it will blend that one
with the next mipmap which is higher resolution than the screen. This still
avoids jaggies but also maintains 1px resolution.

A clutter actor might be painted on a stage view with a view scale
other than 1. In this case, to show the content in full resolution, the
actor must use a higher resolution resource (e.g. texture), which will
be down scaled to the stage coordinate space, then scaled up again to
the stage view framebuffer scale.
Use a 'resource-scale' property to save information and notify when it
changes.
The resource scale is the ceiled value of the highest stage view scale a
actor is visible on. The value is ceiled because using a higher
resolution resource consistently results in better output quality. One
reason for this is that rendering is often not perfectly pixel aligned,
meaning even if we load a resource with a suitable size, due to us still
scaling ever so slightly, the quality is affected. Using a higher
resolution resource avoids this problem.
For situations inside clutter where the actual maximum view scale is
needed, a function _clutter_actor_get_real_resource_scale() is provided,
which returns the non-ceiled value.
Make sure we ignore resource scale computation requests during size
requests or allocation while ensure we've proper resource-scale on
pre-paint.
https://bugzilla.gnome.org/show_bug.cgi?id=765011https://gitlab.gnome.org/GNOME/mutter/merge_requests/3
We need to use pixel size of the monitor in order to generate a valid
texture with full quality for current monitor
In spanned case the background should cover all the differently scaled monitors
thus we scale the texture up to the maximum scaling level and then we resample
it drawing only each side in the monitor it should occupy using the proper
scaling level.
In wallpaper mode (or color mode) for example we don't need to scale the area,
also the texture size we return should be unscaled, not to confuse
MetaBackgroundActor making it use more space than needed.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When we floor the quad coordinates then we've also to enlarge the quad by the
difference between the floored value and the actual coordinate, otherwise
we'd end up in a smaller quad.

When the touch_down event was not delivered to Wayland clients, there's
no point in keeping the touchpoint in our list, so remove it early
inside update() instead of removing it after the touch ended.
This fixes a crash inside touch_handle_surface_destroy() where the
assertion to make sure the surface is removed fails because the
touch_count of the surface never reached 0. This in turn happened
because a new sequence was added, while a (already ended one) wasn't
removed from the touch->touches list before. This caused the touch
counter to get incremented by 1 while no new sequence was added to the
list (because Clutter reuses sequence IDs, the old sequence is equal to
the new one, i.e. the new sequence already is present in the list).

Make the RecordWindow method also understand the 'cursor-mode' property.
For 'embedded' the cursor is drawn onto the pixel buffer using cairo,
otherwise it works similarly to how RecordMonitor deals with it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/413
To be used to translate absolute cursor positions to relative positions,
as well as to determine whether a cursor sprite is inside the stream or
not. It also helps calculating the scale the cursor sprite needs to be
scaled with to be in stream coordinate space.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/413
As the stream size is the logical monitor size multiplied with the ceil
of the logical monitor scale, the corresponding logical size, which is
what should be passed via the size property on the D-Bus object, should
be the logical monitor size.

Make the monitor implementation do things strictly related to its own
source type, leaving the Spa related logic and cursor read back in the

Since commit 8df2a1452c (As pointed out by Robert Mader) we just happened
do this check when doing the first lookup for a Wayland surface for a
XWayland window, when we are later notifying upon surface creation we just
set the relation with no further checks.
The cases pointed out in the comment (eg. window changing decoration) might
presumably happen in a quick enough sequence that we have two scheduled
associations on the fly, so move this check to the more generic
meta_xwayland_associate_window_with_surface() which is called on both
immediate and delayed paths.
https://gitlab.gnome.org/GNOME/mutter/issues/361
There are most likely no GNOME users left still using hardware that
does not support NPOT textures. Further more, they would crash much
earlier and never hit this code-path. So remove the unnecessary check
here.

XWayland creates buffers of the combined size of all connected displays.
This can, especially on older but still in use hardware, exceed the limits
of the GPU.
If that is the case, use `CoglTexture2DSliced` instead of `CoglTexture2D`
https://gitlab.gnome.org/GNOME/mutter/merge_requests/447
We might fail to page flip a new buffer, often after resuming, due to
the FIFO being full. Prior to this commit, we handled this by switching
over to plain mode setting instead of page flipping. This is bad because
we won't be synchronized to the refresh rate anymore, but just the
clock.
Instead, deal with this by trying again until the FIFO is no longer
full. Do this on a v-sync based interval, until it works.
This also changes the error handling code for drivers not supporting
page flipping to rely on them returning -EINVAL. The handling is moved
from pretending a page flip working to explicit mode setting in
meta-renderer-native.c.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/460
A renderer view will, under the native backend, since long ago always
have a logical monitor associated with it, so remove the code handling
the legacy non-stage view case.
https://gitlab.gnome.org/GNOME/mutter/issues/460
Prior to this commit, MetaWaylandSurface held a reference to
MetaWaylandBuffer, who owned the texture drawn by the surface. When
switching buffer, the texture change with it.
This is problematic when dealing with SHM buffer damage management, as
when having one texture per buffer, damaged regions uploaded to one,
will not follow along to the next one attached. It also wasted GPU
memory as there would be one texture per buffer, instead of one one
texture per surface.
Instead, move the texture ownership to MetaWaylandSurface, and have the
SHM buffer damage management update the surface texture. This ensures
damage is processed properly, and that we won't end up with stale
texture content when doing partial texture uploads. If the same SHM
buffer is attached to multiple surfaces, each surface will get their own
copy, and damage is tracked and uploaded separately.
Non-SHM types of buffers still has their own texture reference, as the
texture is just a representation of the GPU memory associated with the
buffer. When such a buffer is attached to a surface, instead the surface
just gets a reference to that texture, instead of a separately allocated
one.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/199
When we freed the cursor GPU state including the gbm_bo objects attached
to it, we didn't unset the cursor renderer private of the CRTCs of the
associated GPU. This means that HW cursor invalidation could potentially
break if a new gbm_bo happened to be allocated at the same memory
address as the previous one.
To avoid this, iterate through the CRTCs of the GPU of which the cursor
data is freed, and unset the cursor renderer private if it was the one
destroyed.
https://gitlab.gnome.org/GNOME/mutter/issues/199
What was actually done when calling meta_wayland_buffer_attach() was
that the texture was realized, so just call the function
`meta_wayland_dma_buf_realize_texture()` and call that.
This is in preparation to change how meta_wayland_buffer_attach() work.

The signal handler must return TRUE as the invocation is already handled
by returning an error. Also update the error message a bit to clarify
that the API exists only for testing purposes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/457
We should not only take the old CRTC for an output whenever
possible, but we should also assign one that is 'free', i.e.
one that another monitor (to be processed after this one)
isn't using, so that that monitor can use the same CRTC.
https://gitlab.gnome.org/GNOME/mutter/issues/373
We shouldn't change an output's CRTC if we don't have to, as
that causes the output to go black.
This patch depends on
"monitor-unit-tests: initial crtcs in custom_lid_switch".
https://gitlab.gnome.org/GNOME/mutter/issues/373
This test forgot to specify the existing CRTC routings in the setup. For the
first output the default 0 was ok, now it is -1 to ensure that the code will
assign it correctly. For the second output the default 0 was incorrect, because
possible_crtcs does not include 0. Now that CRTC is initialized to off
instead, because the second output is hotplugged later and running a CRTC
without an output does not make sense.
This fix will keep this test passing when a future patch attempts to preserve
existing CRTC routings. Assuming that any existing routing is valid, such
routing will be kept. In this test case the existing routing was illegal, it
should have been impossible, which then causes that future patch to fail the
test by assigning the wrong CRTC.
https://gitlab.gnome.org/GNOME/mutter/issues/373
The external grab handler is shared across all external bindings and external
bindings have now different binding flags. For this reason, when rebuilding the
binding table there could be loss of information if we assign the bindings flags
of the external handler to all external bindings. Let's store the bindings flags
in MetaKeyGrab too and use this when rebuilding the binding table to avoid the
above issue.

The "force restore shortcuts" being triggered by a key-combo, there is
no guarantee that the currently focused window is actually non-NULL in
which case we would crash.
Make sure there is a window currently focused before trying to restore
the shortcuts on that window.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/464
On X11, if a window cannot be maximized because its minimum size is
already larger than the output size, a request to maximize will be
ignored.
On Wayland, however, we would still honor the maximize request and
switch the window state to maximized, without actually moving the window
which leads to weird visual effects, as the window end up being
maximized in-place.
To avoid this, make sure the window has the maximize functionality
available prior to change its state in xdg-shell `set_maximized`
request.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/463
As per commit 43633d6b, we mark an unmanaging window as not focusable, while
this is true, it might cause not resetting the current focused window when
unmanaging it causing a crash.
Also this wouldn't allow to check if a window can be focused when unmanaging it,
so let's revert the previous behavior.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/462
This was wrongly done just before enable, which is not right as

This means we need to make sure we don't accidentally free the provided
source GError (which automatically happens with `g_autoptr`), so use
`g_steal_pointer()`.
This fixes an issue where, when launched in a bubblewrap environment
(such as the one provided by Buildstream), mutter would give the
following warning message:
```
mutter-WARNING **: 8:31:35:069: Can't initialize KMS backend: (null)
```
... which isn't that useful when trying to debug the actual issue.
Iterate over all the monitor product words to check for a partial matching on

This adds the required bits to wayland surfaces and ties them up
to the compositor parts.
It is based on and very similar in nature to buffer transforms.
From the specification:
> The global interface exposing surface cropping and scaling
> capabilities is used to instantiate an interface extension for a
> wl_surface object. This extended interface will then allow cropping
> and scaling the surface contents, effectively disconnecting the
> direct relationship between the buffer and the surface size.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/323
This implements the viewporter protocol which offers a cropping and scaling
capabilities to wayland clients.
There are several use cases for this, for example video players and games,
both as a convenience function and as potential performance optimization when
paired with hardware overlays etc.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/323
For various error and warning messages, mutter includes a description of
the window, and that description includes a snippet of the title of the
window. Those snippets find their way into system logs, which then means
they can potentially find their way into bug reports and similar. Remove
the window title information to eliminate this potential privacy issue.
The helper function from gdbus-codegen broadcasts the signal emission,
but we really only care about sending it to the specific peer that
created the session. Thus, only emit the signal to the particular peer
that owns the session.

If the extension is missing, the GPU copy path would not work. The code sets

While adding the necessary return FALSE, also destroy the EGL context we just

If the GPU copy path would use a software renderer, fall back to the CPU
copy path. The CPU copy path is possibly faster and avoids screen
corruption issues that were observed on an Intel Haswell desktop. The
corruption was likely due to texturing from an unfinished rendering or
memory caching issues.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/325
Print the pixel format chosen for an output on a secondary GPU for
debugging. Knowing the format can aid in debugging e.g. red/blue channel
swaps and CPU copy performance issues.
This adds a DRM format printing helper in meta-crtc-kms.h. This header
is included in most native backend files making it widely available,
while DRM formats are specific to the native backend. It could be shared
with Wayland bits, DRM format codes are used there too.
The helper makes the pixel format much more readable than a "%x".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
When setting up an output on a secondary GPU with the CPU copy mode,
allocate the dumb buffers with a DRM format that is advertised supported
instead of hardcoding a format.
Particularly, DisplayLink devices do not quite yet support the hardcoded
DRM_FORMAT_XBGR8888. The proprietary driver stack actually ignores the
format assuming it is DRM_FORMAT_XRGB8888 which results the display
having red and blue channels swapped. This patch fixes the color swap
right now, while taking advantage if the driver adds support for XBGR
later.
The preferred_formats ordering is somewhat arbitrary. Here it is written
from glReadPixels point of view, based on my benchmarks on Intel Haswell
Desktop machine. This ordering prefers the format that was hardcoded
before.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
These functions allow inspecting which pixel formats a CRTC's primary
plane supports. Future patches will inspect the supported formats and
pick a framebuffer format accordingly instead of hardcoding a format.
The copy list function will be used to initialize a formats list, and
the supports format function will be used to intersect that list against
another CRTC's supported formats.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
This avoids having to hardcode the same fallbacks elsewhere multiple
times when determining what formats might be suitable for a set of
CRTCs. The formats_modifiers hash table is now guaranteed to be
populated with at least something, so future code will not need to
handle it being empty.
The hardcoded fallback formats are a minimal set probably supported by
most hardware. XRGB8888 is the format that, according to ancient lore,
all DRM devices should support, especially if they don't have the
capability to advertise otherwise. Mutter also hardcodes XRGB8888 as the
GBM surface format, so it is already required on primary GPUs.
XBGR8888 matches the most common OpenGL format, sans alpha channel since
scanout hardware has not traditionally supported alpha. XBGR8888 is here
also because Mutter hardcodes that format for secondary GPU outputs when
using the CPU copy path.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
If the IN_FORMATS property is not found, copy the formats from the DRM
plane instead. This is the fallback for getting a list of formats the
primary plane supports when DRM universal planes capability is enabled.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
Rather than picking just one format, parse and store all the formats and
their modifiers.
This gives us a list of supported formats (and modifiers) on a CRTC
primary plane. Later I will be using this list to choose a framebuffer
format instead of hardcoding it.

This is done through gtk-shell ATM. If a window requests focus with
an invalid startup ID, just the demands-attention flag will be set.
The "did user interaction happen in between" checks are left to
meta_window_activate_full/meta_window_focus, by passing the timestamp
of the original launch request.
This version has 2 new requests:
- gtk_shell1.notify_launch notifies the compositor that the requesting
client shall launch another application. The given ID is expected to
be unique.
- gtk_surface1.request_focus notifies the compositor that a surface
requests focus due to it being activated. The given ID is passed to
this process through undetermined means, if it corresponds with a
current startup ID and there was no user interaction in between the
surface will be focused, otherwise it will demand attention.
It scaled the logical monitor rect with scale to get the stream
dimensions, but that is only valid when having
'scale-monitor-framebuffers' enabled. Even when it was, it didn't work
properly, as clutter_stage_capture_into() doesn't work properly with
scaled monitor framebuffers yet.

Shell is using these, which was revealed by
1bbb5c8107 breaking its build when
generating its introspection due to meta_startup_notification_get_type()

We keep the class structs private, so in practice MetaStartupSequence
and MetaBackend can't be derived from (the are semi-private).
Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

MonitorManager was inheriting from MetaDBusDisplayConfigSkeleton, this was
causing introspection to see this like a GDBus skeleton object exposing to
clients methods that were not required.
Also, this required us to export meta_dbus_* symbols to the library, while
these should be actually private.
So, make MetaMonitorManager to be just a simple GObject holding a skeleton
instance, and connect to its signals reusing most of the code with just few
minor changes.

pkg-config files for mutter are generated using *_pkg_deps as requires, but
programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.

don't expose such packages to pkg-config, but only use them at build time.

Some types were declared in the public headers so that g-ir-scanner
could resolve the types. This caused warnings when using
-Wredundant-decls, so only redeclare them for the gir scanner.
As with the commits earlier, this also adds const qualifiers where
expected. However, the const variables are casted to non-const variants
so they can be passed to glib functions that take non-const variants but
expect const-like input.
Previously, the clipping rectangle passed to
`meta_surface_actor_get_image()` was updated with the actual texture
size, but recent changes in `meta_shaped_texture_get_image()` now keep
the caller's clipping rectangle unchanged.
The implementation of `meta_window_actor_capture_into()` was relying on
the old behavior of updating the passed clipping rectangle, but now that
it's kept unchanged, the actual clipping rectangle used to copy the data
is wrong, which causes either a distorded image or worse, a crash of
mutter.
Use the resulting cairo image size to copy the data instead of the
clipping rectangle to avoid the issue and get the expected size.

This is a GAppLaunchContext subclass meant to replace usage of
GdkAppLaunchContext in gnome-shell.
Launch contexts get created from the MetaStartupNotification as
they are closely related. The messaging underneath depends on
the availability of a X11 display, if there is one we go through
it (and libsn). If there is none, we still create startup sequences
manually for wayland clients.
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.

The 'cursor-mode', which currently is limited to RecordMonitor(), allows
the user to either do screen casts where the cursor is hidden, embedded
in the framebuffer, or sent as PipeWire stream metadata.
The latter allows the user to get cursor updates sent, including the
cursor sprite, without requiring a stage paint each frame. Currently
this is done by using the cursor sprite texture, and either reading
directly from, or drawing to an offscreen framebuffer which is read from
instead, in case the texture is scaled.

There may be reasons to temporarly inhibit the HW cursor under certain

Mutter prefers platform devices over anything else as the primary GPU.
This will not work too well, when a platform device does not actually
have a rendering GPU but is a display-only device. An example of this
are DisplayLink devices with the proprietary driver stack, which exposes
a DRM KMS platform device but without any rendering driver.
Mutter cannot rely on EGL init failing on such devices either, because
nowadays Mesa supports software renderers on GBM, so the initialization
may well succeed.
The hardware rendering capability is recognized by matching the GL
renderer string to the known Mesa software renderers. At this time,
there is no better alternative to detecting this.
The secondary GPU data is abused for the GL renderer, as the Cogl
context may not have been created yet. Also, the Cogl context would
only be created on the primary GPU, but at this point the primary GPU
has not been chosen yet. Hence, GPU copy path GL context is used as a
proxy and predictor of what the Cogl context might be if it was created.
Mind, that even the GL flavour are not the same between Cogl and
secondary contexts, so this is stretch but it should be just enough.
The logic to choose the primary GPU is changed to always prefer hardware
rendering devices while also maintaining the old order of preferring
platform over boot_vga devices.

create_renderer_gpu_data_egl_device () relied on the primary GPU being
already chosen for the "EGLDevice currently only works with single GPU
systems" error message. A future patch will choose the primary GPU after
this, not before, so this check needs to be rewritten before the
initialization order is changed.
The new check is implemented exactly as the error message says: there
must be exactly one GPU, otherwise fail.

Make the choosing and identity of the primary GPU an internal detail to
the native renderer. MonitorManagerKms did not need it for anything.
The primary GPU logic remains unchanged.
This allows follow-up patches to change how the renderer chooses the
primary GPU. It will be easier for the renderer to use private
information for choosing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/271
This is a step towards moving the primary GPU logic into the native
renderer exclusively. In the future the renderer will have one more
criterion on choosing the primary GPU than MetaMonitorManagerKms should
know about: does a GPU offer hardware rendering.
The choosing of primary GPU is separated from the discovery of GPUs.
When GPUs are discovered and added to the list, the MetaGpuKmsFlag is
now populated correctly and used in choosing.
Choosing the primary GPU is done after all GPUs have been found and is
slightly different from before:
- Skipping devices that do not belong to our seat now works instead of
becoming the primary GPU.
- Fall back to any non-platform, non-boot_vga device if neither kind is
found.
The old preference of platform over boot_vga device is kept.
The hotplug path will continue creating a gpu_kms without flags, because
at that point the primary GPU has already been chosen and the flags are
irrelevant.

I saw Meson fade from the sky
On the wind I heard a sigh
As snowflakes cover fallen Makefiles
I will say this last goodbye
Meson is now coming
So ends Autotools days
Future is now coming
And we must away
Over Python and without Bashisms
Through lands where never Meson touched
By silver streams that run down to the Sea
Under parsers, beneath old legacy
Over snow one winter’s morn
I turned at last to paths that lead home
And though where the road then takes me
I cannot tell
We came all this way
But now comes the day
To bid you farewell
Many places I have been
Many sorrows I have seen
But I don’t regret
Nor will I forget
All Makefiles that took that road with me
I bid you all a very fond farewell.
