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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2165>
It uses the org.gnome.SettingsDaemon.Power.Screen D-Bus API. Currently
brightness set if the proxy is not ready are ignored; whether the
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.

Tests that test case EDID is setup correctly, and that color devices for
monitors are created.

Ready means it has established the connection to colord and can operate.
Will be used by tests to make sure tests don't fail due to race
conditions when connecting to colord.

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.

It's not really about monitors, even though it is used for monitors.
Lets shrink MetaMonitorManager a bit moving it to the backend.
While at it, stop leaking it too.

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
comparing the EDID vendor/product/serial fields. Whene these are
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
to more reliably know when there was EDID telling us about these
details. This will be used for colord integration.

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.
Will later be used to feed correct information to colord.

Create a color manager type that eventually will be the high level
manager of color related behavior, such as ICC profiles and
color "temperature" a.k.a. night light.
For now, it's only an empty shell. It's also constructed by the actual
backend, as at a later point, the X11 and native color management
implementations will differ.

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.
Revert to legacy KMS which has no such problem with non-default modes.

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.

Since commit 1bf70334 "tests/runner: Make test runner use the headless
backend", tests are run with the native backend in headless mode, which
will attempt to open each GPU and show a warning (fatal during tests)
if it cannot.
However, in headless mode we might not be logged in on any seat (for
example we might be logged in via ssh instead), which means we might
legitimately not have permission to use any GPUs, even if they exist.
Downgrade the warning to a debug message in this case.

This adds the 4 new connector types that mutter didn't know about from
drm_mode.h in the kernel.
Noticed because mutter kept crashing when plugging in a USB-C adapter to
use an external monitor.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2577>
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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
The resulting logical monitor was eventually marked as primary anyway,
but without the config being marked as such, various primary properties
was not set e.g. the one on the MetaOutput. Also, tests would fail.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
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
if clients pre-rotated the buffer using
`wl_surface::set_buffer_transform`, visually matching the
hardware cursor path.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/344>
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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2442>
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.

It papered over wrong `meta_rectangle_transform()` behaviour for
non-flipped output transforms. Also there is no obvious reason
why we would need inverted values here.

- Drop bogus `meta_monitor_transform_invert()`. It papered over
wrong `meta_rectangle_transform()` behaviour for non-flipped
output transforms.
- 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.
- While on it, drop a redundant `return`.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
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.
Fixes: 81b28a1d97
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.

The name had a bit conceptual conflicts with MetaKmsUpdate, as it shared
its namespace but had no relation to it. Fix this by renaming it
MetaKmsResourceChanges (and the corresponding META_KMS_UPDATE_CHANGE_*
to META_KMS_RESOURCE_CHANGE_*). The term "resource" is used since that's
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
data and can thus only check for the new or the old behaviour.

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
and should be set to 0.
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.
