The HDR Static Metadata InfoFrame contents are described in CTA-861.3
and the kernel maintains a representation of that in `struct
hdr_metadata_infoframe` in `include/uapi/drm/drm_mode.h`.

The Colorspace property informs the display about the colorimetry of the
content. Only variants supported by the sink are exposed in the
property. The strings representing the color spaces are undocumented but
can be found in the `hdmi_colorspaces` list in
`drivers/gpu/drm/drm_connector.c` in the Linux kernel (v 6.2).
The HDR_OUTPUT_METADATA property is a blob with the InfoFrame content.
We have to query support for the different values in the struct from the
EDID/DisplayID ourselfs.

This adds a new 'experimental-hdr' string property to the MonitorManager
which can be changed from looking glass.
Currently when the string equals 'on', HDR (PQ, Rec2020) will be enabled
on all monitors which support it. In the future support for more
transfer functions and color spaces as well as HDR metadata can be
added.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2879>
The color space and HDR metadata are eventually sent as metadata to the
display. The color space informs the display of the colorimetry of the
frames we produce, the HDR metadata informs the display of the transfer
function and additional mastering display colorimetry and luminance to
guide tone and gamut mapping.
The only color spaces we support right now are the default color space
and Rec bt.2020 which is typically used for HDR content. Other supported
color spaces can be added when needed.
The default color space corresponds to whatever colorimetry the display
has when no further changes are made to the calibration of the display.
The colorimetry is communicated to sources via EDID/DisplayID.

We relied on them being valid longer to keep track of used GPUs. If we
don't have the CRTC (or output) we don't have a way to fetch the pointer
to the MetaGpu that drives the associated monitor.
This avoids a crash when trying to fetch said pointer from what would be
the NULL MetaCrtc pointer.

When an onscreen is "attached" it means it has an active CRTC and output
it interacts with, e.g. listens to configuration changes to update gamma
and privacy screen state.
MetaOutput and MetaCrtc are rather short lived objects meaning they are
disposed of and regenerated each time the compositor reloads monitor
resources, and while MetaOutput are indirectly kept alive due to the
MetaMonitor holding on to them during reloading, the same does not apply
to MetaCrtc, so to avoid trying to disconnect our signals from
disappeared outputs and CRTCs when we dispatch, hold our own references
to these objects.

As implemented in colord 1.4.6, cd_icc_load_handle() has three possible
results:
1. success, taking ownership of the profile;
2. failure because cmsGetProfileContextID returns NULL, *not* taking
ownership of the profile;
3. failure in cd_icc_load(), taking ownership of the profile.
The previous commit ensures that we are not in case 2.
In case 3 where cd_icc_load() fails, ownership was already given to
the colord CdIcc object, so it will be freed when the g_autoptr unrefs
the CdIcc, and we must not free it again: that would be a double-free,
potentially resulting in memory corruption.

We want to avoid using too high scales too easily, which started to
happen 2f1dd049bf ("monitor-manager: Rework default scale factor
selection"). Instead of using the closest non-fractional scale, which
effectively is what we'd do, only round upwards if we're closer than
0.25 (25%).
Since there are some wiggle room for scales to make the logical
resolution on the integer pixel grid, make sure to compensate. This
compensation is done by adding an extra 0.2 to scale difference.
For example the following fractional scales will get these corresponding
integer scales:
* 1.25 -> 1.0
* 1.5 -> 1.0
* 1.75 -> 2.0
* 2.0 -> 2.0
* 2.50 -> 2.0

As part of https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/525
(introduction of transactional KMS API), the logic determining whether a
GPU can have outputs was changed from whether any connectors existed to
whether any connected connectors existed. That effectively meant that we
wouldn't attempt to start at all if there were no monitors connected
while starting up.
This was unintentional, so lets revert back the expected behavior.

In order to make things more and more asynchronus and to each time we
paint be an isolated event, that can be potentially be applied
individually or together with other updates, make it so that each time
we draw, we use the transient MetaFrameNative (ClutterFrame) instance to
carry a KMS update for us.
For this to work, we also need to restructure how we apply mode sets.
Previously we'd amend the same KMS update each frame during mode set,
then after the last CRTC was composited, we'd apply the update that
contained updates for all CRTC.
Now each CRTC has its own KMS update, and instead we put them in a per
device table, and whenever we finished painting, we'll merge the new
update into any existing one, and then finally once all CRTCs have been
composited, we'll apply an update that contains all the mode sets for all
relevant CRTCs on a device.

MetaRendererViewNative is a MetaRendererView which contains logic
specific to views of the native backend. It will be used by following

Instead of using the "discarded" page flip callback when the
"discarding" happened during actual immediate processing, communicate
the same via the KMS update feedback.
The "discarded" page flip callback is instead used only for when a
posted page flip is discarded. In the atomic backend, this only happens
on shutdown, while in the simple backend, this also happens when a
asynchronous retry sequence eventually is abandoned.
This allows further improvements making KMS handling fully async.

At first it was called seal(), but then updates could be amended after
being posted, given a flag. That flag has been removed, so we can go

We test direct client buffer scanout using a TEST_ONLY commit on atomic,
and with various conditions in non-atomic, but if we end up failing to
actually commit despite this, handle the fallout asynchronously. What
this means is that we'll reschedule a new frame immediately.
For this to work, the same scanout buffer needs to be avoided for the
same CRTC. This is done by using the newly added signal on the
CoglScanout object to let the MetaWaylandBuffer object mark the current
buffer as non-working for the onsrceen that it failed on. This allows to
re-try buffers on the same onscreen when new ones are attached.
This queues a full damage, since we consumed the qeued redraw rect. The
redraw rect wasn't lost - it was accumulated to make sure the whole
primary plane was redrawed according to the damage region, whenever we
would end up no longer doing direct scanout, but this accumulation only
works when we're not intentionally stopping to scanout. For now, lets
just damage the whole view, it's just an graceful fallback in response
to an unexpected error anyway.

If we get a "ready" page flip feedback, it means the page flip was
symbolic, i.e. not real, e.g. as a result of an update that didn't
change the state of the primary plane. Warn if there is a "next fb"
meaning we expected to have a new buffer that we flipped to.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2854>
This is intended to be used only for plane assignment, and CRTC like
changes, so that one can e.g. change a cursor plane on a pending update
that changes the primary plane, before it has been committed to KMS.
The kms-updates test overrides the get-state function MetaKmsCrtc. This
is needd to not have the update mechanism not clamp the gamma size to 0,
as vkms reports the gamma length 0. By pretending it's 3, we can test a
simple and small gamma lut is merged correctly when merging updates.

The pointer to the manager, the peer name and the ID are things that are

This class is intended to be used as a base class for D-bus interface
implementations that deal with "session" objects, i.e. a D-Bus object
representing a certain session of some kind, e.g. a screen cast session.

generates IDs, handles shutdown procedures.

It's currently not set by anything, and will only be used by

This means the MetaDbusSession interface takes a more active role
instead of being something that more or less sends signals to the
interface implementor. This will allow better control when using
MetaDbusSession to manage these sessions, instead of their non-abstract
variants.

If the device supports the atomic API the property based API is used to

to update the state.

With detach meaning having the onscreen stop listening on configuration
changes on the corresponding backing mode setting objects. We need to do
this as there is a time between rebuilding the views, and that the new
mode sets are called, where the old onscreen is kept alive, but the
stage view is gone. At this point in time, if privacy screen or gamma
configuration changes, e.g. by the night light temperature changing, the
onscreen would attempt to schedule an update on the now gone stage view.
This commit also renames the "keep onscreen alive" to "detached
onscreens" to more clearly communicate that it's detached onscreens from
their corresponding mode setting objects.

For the coordinates of pointers or stylii, we translate the ones we store
using the viewport matrix already. For touch events otoh, we store coords
untranslated and translate them later only for event emission.
Let's be consistent here and store the coordinates of touch events
translated, just like we do for pointer events.
This fixes touch window dragging on rotated monitors. MetaWindowDrag calls
clutter_seat_query_state(), which uses those stored coordinates. So in case
of a touch sequence the coords returned by query_state() would be
untranslated.

Streams are generally recoverable by the client and errors may happen
e.g. on negotiation failures. Right now we close the stream and
corresponding session, which is neither necessary nor expected by
clients.
Just disable the stream instead and let clients handle things as they
seem fit. This allows clients to e.g. try several Gstreamer pipelines
with limited caps on a single stream.

Doing it in dispose means the backend is actively tearing down itself,
meaning various components might or might not be there, depending on how
the tearing down is implemented. Make things a bit more robust by doing

The first monitor in stacking tests is the primary monitor but that
doesn't have to stay this way forever. Instead of special casing the

The previous logic tried to keep the position of the top left corner of
the window relative to the top left corner of the monitor. This allowed
the window to move out of the target monitor. This change keeps the
proportions of the distance between the window and the monitor borders
instead if possible. Otherwise it keeps the relative position of the
center of the window clamped to [0,1] to make sure the window lands on
the right output.
This also slightly changes what monitor is considered to be on: the
monitor which contains the center of the window and, if the center is on
no monitor, the monitor wich overlaps the most with the window.

So we can remove the additional `next_fb` and `current_fb` pointers from
`MetaOnscreenNativeSecondaryGpuState`.
Some non-scanout buffers also need to be held in the case of GL blitting

As with CRTC GAMMA_LUT, we're moving towards making the entity managing
KMS updates aware if there are any changes to be made, and whether KMS
updates are actually needed or not, and for privacy screen changes, this
means we need to communicate whether the privacy screen state is valid
or not. This allows the caller to create any needed MetaKmsUpdate.

When the pointer crosses monitors, we account for a single motion event
resulting in the pointer moving across more than 2 monitors, in order
to correctly account each monitor scale and the distance traversed
across each monitor in the resulting relative motion vector.
However, memory on the direction is kept short, each iteration to
find the target view just remembers the direction it came from. This
brings a pathological case with 4 monitors with the same resolution
in a 2x2 grid, and a motion vector that crosses monitors at the
intersection of all 4 in a perfect diagonal. (Say, monitors are
all 1920x1080 and pointer moves from 1920,1080 to 1919,1079).
In that case, the intersection point at the crossing between 4
monitors (say, 1920,1080) will be considered to intersect with 2
edges of each view. Since there is always at least 2 directions to
try, the loop will always find the direction other than the one
it came from, and as a result endlessly jump across all 4 possible
choices.
In order to fix this, consider only the global v/h directions,
we already know if the pointer moves left/right or up/down, so
only consider those directions to jump across monitors.
For the case at hand, this will result in three monitors visited,
(either bottomright/bottomleft/topleft, or bottomright/topright/topleft)
with a total distance of 0,0 in the middle one, effectively
resulting in a correct diagonal motion.

Writing to fields (in this case the MetaColorDevice::pending_state) in
response to an asynchronous operation that was cancelled means we'll
write to an arbitrary memory location, potentially causing segmentation
faults or memory corruption.
Avoid these segfaults or memory corruption by only updating state if we
weren't cancelled. Also avoid trying to dereference the device pointer
if we're cancelled.
The memory corruption due to this has been causing test flakyness in the
monitor unit tests due, which should now hopefully be fixed.
