This means that e.g. custom profiles or calibrated profiles will be
added and registered with colord. This does not use CdIccStore for two
reasons: don't want to generate duplicate entries for auto-generated
EDID or EFI profiles, and we want to store profiles as MetaColorProfile.
It also happens to be the case that CdIcc does synchronous I/O, which
should be avoided everywhere except on startup.

It will be used to generate gamma look up tables depending on
temperature.
The temperature comes from org.gnome.SettingsDaemon.Color and
depends on the current night light state.

It uses the org.gnome.SettingsDaemon.Power.Screen D-Bus API. Currently

brightness value should be cached and set once it appears or whether
color profiles should be reapplied is yet to be decided.

Instead of passing 4 arguments (red, green and blue arrays as well as a
size), always pass them together in a new struct MetaGammaLut. Makes
things slightly less tedious.
The KMS layer still has its own variant, but lets leave it as that for
now, to keep the KMS layer "below" the cross backend CRTC layer.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2165>
In practice, for KMS backend CRTC's, we cache the gamma in the monitor
manager instance, so that anyone asking gets the pending or up to date
value, instead of the potentially not up to date value if one queries
after gamma was scheduled to be updated, and before it was actually
updated.
While this is true, lets still move the API to the MetaCrtc type; the
backend specific implementation can still look up cached values from the
MetaMonitorManager, but for users, it becomes less cumbersome to not
have to go via the monitor manager.

We created device profiles, that we manage the lifetime of in colord,
but color devices can be assigned profiles other than the ones it was
created for. For example, this can include the standard sRGB profile
provided by colord.
To achieve this, keep track of the default profile of the CdDevice as
the "assigned" color profile of the device. Given this profile
(CdProfile), construct a MetaColorProfile that can then be interacted
with as if it was generated by ourself.
The assigned profile (default profile in colord terms) does nothing
special so far, but will later be used to determine how to apply CRTC
gamma ramps etc.
The sRGB.icc file used in the tests was copied from colord. It was
stated in the repository that it has no known copyright restrictions.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
This works similiarly to how MetaColorDevice works, by creating them
asynchronously then signalling the 'ready' signal when done. Also
similarly to MetaColorDevice, the on-demand sync cleanup on finalize is
added, to avoid race conditions when hotplugs happens very rapidly,
e.g. in tests.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
Just as gsd-color does, generate color profiles. This can either be done
from EFI, if available and the color device is associated with a built
in panel, or from the EDID. If no source for a profile is found, none is
created.
The ICC profiles are also stored on disk so that they can be read by
e.g. colord. The on disk stored profiles will only be used for storing,
not reading the profiles, as the autogenerated ones will no matter what
always be loaded to verify the on disk profiles are up to date. If a on
disk profile is not, it will be replaced. This is so that fixes or
improvements to the profile generation will be made available despite
having run an older version earlier.
After generating, add some metadata about the generated file itself
needed by colord, i.e. file MD5 checksum and the file path.

gsd-color provides this API, which exposes details about the night light
state. Currently, gsd-color also turns this state into CRTC gamma
changes, but this will eventually change, and this is a preparation for
this.
The proxy isn't yet used for anything.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
Previously, gsd-color handled adding color devices. It got information
about those via the GnomeRR API, which is part of libgnome-desktop.
libgnome-desktop itself got this information from the
org.gnome.Mutter.DisplayConfig.GetResources() D-Bus method, implemented
by mutter.
Now, mutter itself will add all the monitor color devices itself,
without having to go via gsd-color.
We sometimes need to delete colord devices synchronously, in certain
race conditions when we add and remove devices very quickly (e.g. in
tests). However, we cannot use libcolord's 'sync' API variants, as it
has a nested takes-all main loop as a way to invoke the sync call. This
effectively means we end up sometimes not return from this function in a
timely manner, causing wierd issues.
Instead, create our own sync helper, that uses a separate context that
we temporarly push as the thread-default one.

What determines whether one MetaMonitor is the same as the other should
be whether the actual monitor is the same. The way to check this is

incomplete, fall back on the 'winsys ID'.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2141>
Same applies to MetaOutput. The reason for this is to make it possible

As for the types of monitor, X11 and KMS are currently assumed to always be
physical, while the virtual ones are assumed to be virtual. In theory
X11 ones could be virtual, but lets not bother. KMS ones can be virtual
in the case of virtual KMS, but we typically use that for testing as if
it was physical, so lets leave it as such.

Although its atomic KMS support seems to work at first, mode sets to
anything other than the Xilinx preferred max resolution of 2048x1280
would result in a hang. The xlnx kernel driver is given:
`DRM_MODE_ATOMIC_ALLOW_MODESET | DRM_MODE_PAGE_FLIP_EVENT`
and it does complete the mode set without error, but page flip events
never arrive and so you're frozen on the first frame.

The "activate" and "deactivate" signals on ClutterStage are used by
Cally to track the key-focus when the user is interacting with shell UI.
key-focus only gets tracked while the stage is activated.
Wayland has no concept of the stage receiving focus or not, so right now
the activation state is bound to whether there's a focus_window in
meta_display_sync_wayland_input_focus(). Since display->focus_window is
set pretty much all the time, this effectively binds activation state to
whether the stage holds a grab or not. This is almost good enough, but
it misses cases where key-focus is on the stage without a grab, for
example when keyboard-navigating the panel after using Ctrl+Alt+Tab.
It seems to make more sense to bind the activation state to whether
key-focus is set to an actor or to NULL, so let's do that instead.

This adds the 4 new connector types that mutter didn't know about from

When we e.g. generate switch configs (i.e. the ones from pressing the
Super+P or the switch-config key on laptops), try a bit harder to find a
"good" monitor scale.
With "good", it means pick a scale that was used in a previous
configuration. In practice, this means that if you for example have
configured your external monitor to use a specific scale, then pressed
e.g. "built in only", and then switched back to e.g. "external only" or
"linear", the generated configuration will use the scale that was
previously configured.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.
This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
This will eventually help with better hueristics for finding a good
scale. It currently doesn't change much, but the helper will later gain
more functionality that will also help when coming up with mirroring
configs.

The resulting logical monitor was eventually marked as primary anyway,

This will allow tests to change monitor resolution. The first argument
is the monitor ID; there is always one monitor added by default, and it
has the id 0. It's currently not possible to add more monitors, so
passing '0' is the only valid way to resize monitors.

This allows the GL fallback path to correctly paint the cursor

When taking the scanout path we still want to clear the
redraw-clip from the stage-view in order to ensure we skip
frames in `handle_frame_clock_frame()` if no new redraw-clip
was recorded.
This was not done previously as the accumulated redraw-clip was
needed for the next repaint, likely under the assumption that
scheduling a scanout repeatedly would be computationally cost-free.
This assumption does not hold in a VRR world.
In order to archive both, an accumulated redraw-clip for the next
paint and frame-skipping during scanout, introduce new API to defer
and accumulate redraw-clips until the next repaint.

We disable modifiers for two reasons: an udev rule saying so, or the
lack of a working drmModeAddFB2(). However, to the users, this is not
granular enough. While the current user, whether to enable modifiers in
MetaRendererNative, doesn't need more granularity, we want to send
modifiers to Wayland clients even if the onscreen framebuffers should
still be allocated without modifiers.
Prepare for differentiating between how Wayland DMA buffers work and how
onscreen buffer allocation work by separating the relevant device flags.

This one does proper error reporting. Via Javascript, barriers are
constructed directly via GObject construction, which currently can't
handle error reporting, but when calling from C we can. However, if we
initialize using GInitable, and use that in our constructor method, once
gjs gains support for construction using GInitable, including the error
reporting, we'll automatically get proper error reporting to Javascript.

Prior to this commit, barriers were created with a MetaDisplay pointer,
despite being entities related and owned by the backend. In the X11
case, it was also not hooked up to the backend X11 connection, but the
clutter one, meaning for example that the logic was active (but dormant)
also for the Xwayland connection.
Fix this by moving X11 barrier management and event processing fully to
the backend. Also replace passing a display pointer with passing a
backend pointer. Keep the display pointer around for a release, but mark
it as deprecated.

wrong `meta_rectangle_transform()` behaviour for non-flipped

- Update `scale_and_transform_cursor_sprite_cpu` to match the GL
pipeline matrix in `MetaShapedTexture`, fixing several of the
flipped cases. Note: the rotation applied is the one a client would
need to apply to the buffer for a given monitor transform.

The following implicit definition for `transform()` did not
correctly apply:

a * b = c
c * invert(b) = a
```
Crucially the following did not apply for `FLIPPED-90`
and `FLIPPED-270`:
```
a * invert(a) = identity
```
Fix this by applying the operations, first the flip, then the
rotation, in this order and add tests to ensure correct results
for the requirement above.
Also drop `relative_transform()` as it only had a single user and
can be replaced by `transform()`:
```
invert(a) * b = c
a * c = b
```
As this is not very intuitive, ensure in tests as well.

Checking for both bits at once means only one matching bit is
sufficient - very likely in case of `rotate-0'.
This fixes crashes on hardware that does not support 'reflect-'
bits when setting a flipped output transform.
While on it, also update the check for `reflect-y` instead of
`reflect-x` + `rotate-180`. They are logically equivalent,
however some hardware may support `reflect-y` but not both
other bits.

We started to report resource changes using prediction when an update
had been successfully committed. While at it, gamma changes were
reported too, but this was problematic, as gsd-color will listen for the
MonitorsChanged D-Bus signal and naively set the gamma again, even if it
didn't change. There aren't currently any actual use cases for being
told when gamma changes from a prediction, so just ignore it and just
report privacy screen changes.
This avoids a feedback loop between mutter and gsd-color.

Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2531>
When we change the privacy screen, we added a result listener to the KMS
update object to notify the upper layer about the privacy screen state
change. This was slightly awkward as one might have changed the state
multiple times for a single update, thus it was necessary to remove any
old result listeners to an update before adding a new one.
Doing this will not be possible when updates are fully async and managed
by the KMS impl device.
To handle this, instead make the post-commit prediction notify about
changes that happens in response to a successfully committed update. We
already predicted the new privacy screen state, so the necessary change
was to plumb the actual change into a callback which emits the signal if
there actually was a privacy screen change.
This will then be communicated via the same signal listener that already
listens to the 'resources-changed' signal.

its namespace but had no relation to it. Fix this by renaming it
MetaKmsResourceChanges (and the corresponding META_KMS_UPDATE_CHANGE_*

already used in the signal, and the fact that the changes partly comes
from changes in the DRM resource as retrieved by drmModeGetResources.

With this header we can set a flag to signal that the whole buffer is
corrupt and should be ignored. With this we can cater to all cases:
* Window buffer fine, but cursor broken:
Use the spa_meta_cursor properties like id or offset accordingly
* Window buffer broken, but cursor fine:
Use the chunk flags
* Both are broken / the dequeued buffer is not usable
Use the spa_meta_header flag
Additionally clients can now check if a buffer contains spa_meta_header

PipeWire supports flags to signal a corrupted buffer. We should use the
flag SPA_CHUNK_FLAG_CORRUPTED for `chunk->flags` instead of setting
`chunk->size = 0` since the size isn't well defined for arbitrary dmabufs

Sadly clients like obs are using a chunk size of 0 to decide if a buffer
should be imported. Thus we should offer both until clients are using
the flag.

The pixel clock determines how fast pixels can be processed. When adding
non-native common modes, avoid adding modes that exceed the max pixel
clock frequency of the native modes. Avoiding these avoids potential

'screen-cast/monitor-src: Use clutter_stage_paint_to_buffer'
(6c818cd8d5) made the non-dma-buf path use
clutter_stage_paint_to_buffer() to avoid running into direct scanout
issues. At a glance, the dma-buf paths didn't have the same issue since
it explicitly handled dma-bufs by blitting them.
What it also did was move the recording to an idle callback, to avoid
paint reentry issues. A side effect of this, however, is that it also
broke the dma-buf paths, as they rely on the back buffer existing, and
the stage view direct scanout already being setup, which it isn't in an
idle callback.
Fix this by using the dma-buf variant of
clutter_stage_paint_to_buffer(): clutter_stage_paint_to_framebuffer().
This has some negative performance impact, but we can't use
cogl_blit_framebuffer() when using an idle callback for recording.
Potential performance improvements to make things work more as they did
before is to enhance 'cogl_blit_framebuffer()' a bit, making it a vfunc
that could be implemented by MetaOnscreenNative. A flag to say whether
to look at the back or front buffer would let MetaOnscreenNative know
whether to use the already committed-to-KMS buffer, or the current back
buffer.

The monitors settings such as the privacy screen property is propagated
to the monitors via kms updates, however during initialization and

such settings are added to the queue before the backend has fully

With the unthrottled input emission, we ended up often getting the

sending a cursor-only frame after any damage and relayout has been

MetaCursorRendererNative only updates the cursor state when the
underlying texture changes. The cursor scale and transform do not
trigger updates. This results in wrong cursor orientations on rotated
displays. Use both texture changes and scale and transformation changes

We rather confusingly still call a secondary display card that is
GPU-less (DisplayLink or other basic KMS device) a "secondary GPU",
so just because secondary_gpu_state is non-NULL doesn't mean we
can use it for rendering. The clearest indication of this is when
there is no EGL surface.

Since devices may be multiple things now, check all capabilities in order
to ensure all aspects of the device are correctly configured.
This change does the following observations:
- Devices that have TOUCHPAD | POINTER capabilities prefer the 'touchpad'
settings path. The regular pointer settings path is left for all
non-touchpads.
- Devices that are both a tablet and a touchscreen prefer the tablet
relocatable schema. This works for both aspects as the touchscreen
schema is a subset of the tablet one.
Other than that it's a rather boring, even if verbose search and replace.

If the remote desktop service emits absolute input events (e.g. absolute
pointer events) before the stream has started streaming, we don't have a
virtual monitor, as the size has not been negotiated yet. When this

make sure not to send events before the streaming has started, but them
doing so anyway shouldn't trigger a crash, which would be the case
otherwise.

Keep the virtual monitor around if it's being resized. This reduces the

We'll change mode's on-demand so using IDs identical to the virtual

We now only enable DMA buffer based PipeWire screen casting if a
format/modifier has been negotiated. This practically means a consumer
is aware about what is needed, and we should not try to predict that it
uses the DMA buffer the right way (i.e. not mmap:ing directly).
However, in case we're not hardware accelerated, we never want to
attempt to use DMA buffer screen sharing, as we want to avoid
compositing into a DMA buffer on such hardware as doing so can be very
slow.

When handling lid state, we used to update the idle time right after
opening the lid. This behavior changed in commit 14b6c8780d due
to a typo/thinko, "if (lid_is_closed)" used to be an early return
condition before updating idle time, now it only updates in that
case.
Restore the original behavior, since this idle time update is key
in having gsd-power light up the display again, this presumably
fixes situations that required extra "light up" hints after suspend.
What it does surely fix is "ninja test" in g-s-d against recent
mutter, since the behavioral change induced a test timeout there.

Returns TRUE if the active renderer backend can allocate DMA buffers.
This is the case hardware accelerated GBM backends, but FALSE for
surfaceless (i.e. no render node) and EGLDevice (legacy NVIDIA paths).
While software based gbm devices can allocate DMA buffers, we don't want
to allocate them for offscreen rendering, as we really only use these
for inter process transfers, and as buffers allocated for scanout
doesn't use the relevant API, making it return FALSE for these solves
that.

Because both code paths require the existence of `GL_TIMESTAMP[_EXT]`
which is only guaranteed if `ARB_timer_query` (included in GL core 3.3)
is implemented.
We know when that is true because `context->glGenQueries` and
`context->glQueryCounter` are non-NULL. So that is the minimum
requirement for any use of `GL_TIMESTAMP`, even when it is used in
`glGetInteger64v`.
Until now, Raspberry Pi (OpenGL 2.1) would find a working implementation
of `glGetInteger64v` but failed to check whether the driver understands

There was a sanity check that complained if there was still a "next
framebuffer" when disposing an onscreen. This is correct to complain
about under normal operation, as we always wait until receiving the page
flip callback before cleaning up the onscreen and their state.
However, when there are many hotplugs occurring, we might end up with
race conditions when the above sanity check is not valid: when we have
more than one monitor active, paint 1 one of them, but receive a hotplug
event before we paint the other(s), we will discard the already painted
onscreen before really issuing a page flip.
In this situation, we will have the "next framebuffer", but having that
is not a bug, it's a race condition, thus to not leak in this situation,
make sure to clean up the next framebuffer here too.

post the update, another hotplug event happens, we'd have stale pending
KMS update. When that update eventually would be processed, we'd try to
apply out-of-date updates which may contain freed memory.

When the before-paint function is executed, it's only purpose
is to check if there's any scanout queue, and immediately
record it if any.
However, since [1], we regressed in this specific case with the
introduction of an idle callback in the before-paint function.
The regression only happens when the PipeWire stream is using
DMA-BUF buffers, and it would operate as follows:
1. In before-paint, when there's a scanout available, we queue
an idle callback to capture the monitor. The idle callback
(almost always) executes after the scanout is pulled from
the stage view
2. meta_screen_cast_stream_src_maybe_record_frame() is called
by the idle callback. In the DMA-BUF case, it then runs
meta_screen_cast_monitor_stream_src_record_to_framebuffer()
3. In meta_screen_cast_monitor_stream_src_record_to_framebuffer(),
because the stage view doesn't have a scanout anymore, it
ends up calling cogl_blit_framebuffer() with the stage view
framebuffer. This is the regression bug.
This regression presents itself in the form of the screencast
stream showing the desktop when there's an unredirected fullscreen
application window running.
Revert before-paint - and only that - back to immediately capturing
any available scanout. Only record these frames when the target
buffer is a DMA-BUF handle. Nothing is captured on before-paint if
the stream is not using DMA-BUF, since the regular paint routine
will handle these frames regularly post-paint.

This API can be used to construct a MetaKmsUpdate with plane assignments
that in isolation will be tested against the current KMS state. How it
is tested depends on the KMS implementation; in the simple / legacy KMS

(dimension, stride, format, modifiers, all must match), and with atomic
KMS, it uses the TEST_ONLY on a real constructed atomic mode setting

Commit 2289f56112 ("monitor-manager: Don't apply unneeded orientation
changes") added an early return to handle_orientation_change () in case
the transform is unchanged.
But this did not take the correction of the transform for devices
with 90° mounted panels into account causing a desired orientation
change to get skipped if the new orientation matches the corrected
logical orientation from the previous transform setting.
Fix this by calling meta_monitor_crtc_to_logical_transform () on the
transform before comparing it, matching the

The GBM support in the NVIDIA driver is fairly new, and to make it
easier to identify whether a problem encountered is related to using GBM
instead of EGLStreams, add a debug environment variable to force using
EGLStream instead of GBM.
To force using EGLStream instead of GBM, use
MUTTER_DEBUG_FORCE_EGL_STREAM=1

Since this signal is in a hot path during input handling, it makes sense
not to have this be a signal at all, currently most of the time spent in
it is in GLib signal machinery itself.
Replace it with a function/user data pair that are set on the sprite
itself. Only the places that create an sprite are interested in hooking
one ::prepare-at behavior per sprite, so we can do with a single pair.
This makes meta_cursor_sprite_prepare_at() inexpensive enough.

Let the meta_cursor_sprite_realize() function return a boolean value
telling whether there was an actual change in the sprite cursor. E.g.
the surface/icon for it changed in between.
This is used in the native backend to avoid converting/uploading again
the cursor surface.

MetaBackend can now show whether it is in headless mode or not
using a vfunc is_headless.
Fallback of is_headless returns FALSE.
MetaBackendNative implements is_headless returning its
is_headless property.

This is a strange thing to do since MetaInputMapper also does take care of
devices with an output configured through settings, since we might have
devices that were configure through settings exclude other devices that
belong together with an output (e.g. a display-integrated tablet).
This was essentially here as a last resort to avoid matching two very
similar looking tablets to one of two very similar looking outputs. There
was a 50% chance already that the choice was wrong, and now these devices
can all be configured specifically through settings, so this shouldn't
be missed either.

Non-display-attached tablets (e.g. Intuos) may find no match, which
should mean "use the span of all monitors", not "pick one for me".
Reserve this fallback to touchscreen devices, since these might
still benefit from it.

The matrix and aspect ratio of the tablet is irrelevant on pads, and
it actually triggers warnings when trying change that on those devices:
gnome-shell:42536): mutter-CRITICAL **: 17:22:41.994: meta_input_device_native_get_mapping_mode_in_impl: assertion 'device_type == CLUTTER_TABLET_DEVICE || device_type == CLUTTER_PEN_DEVICE || device_type == CLUTTER_ERASER_DEVICE' failed
This is unnecessary to do on pad devices, these just need to be moved
together with their respective stylus.

The cursor renderer shouldn't assume all the CRTCs of a logical are KMS
CRTC's, as we'll end up checking hardware capabilities for CRTC's of
virtual monitors as well, when they were created to not embed the cursor
image directly in the framebuffer.
Instead, use the newly introduced API for checking CRTC cursor
capabilities. This fixes a crash with the following backtrace:

On a KMS backed CRTC, hardware cursor are supported when there are
cursor planes to assign them to. Note that when using legacy mode
setting, fake cursor planes are added when adequate.
On virtual CRTCs, used with virtual monitors, the equivalent of hardware
cursor are always supported, as they are sent using embedded PipeWire
stream metadata.

It was dropping to zero after the first frame because it hadn't been
incremented high enough. So the second frame would crash with:
```
#0 g_type_check_instance_cast
#1 META_DRM_BUFFER
#2 copy_shared_framebuffer_cpu
```
That's the CPU-copy path (fallback-fallback) that probably no one is using
but it does work after this fix. Exactly the same issue as was fixed
in `copy_shared_framebuffer_primary_gpu` by 36352f44f9.

If some connectors disappeared, but the rest didn't change, we missed
actually removing the ones that disappeared, as we incorrectly assumed
nothing changed. Fix this by only assuming nothing changed if 1) we
didn't add any connector, and 2) we have the same amount of connectors
as before the hotplug event. The connector comparison checking makes
sure we report changes if anything of the still available connectors
changed.
