45bda2d969 renderer/native: Detach old onscreens when rebuilding views
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.

d6062baef3 backends/native/seat-impl: Translate touch coords before storing
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.

c6b454d00f kms: Prepare shutdown on 'prepare-shutdown' signal
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
any work that might rely on the backend being there before shutdown is
done in response to the 'prepare-shutdown' signal being emitted by the
backend.

733aa0e3b7 onscreen/native: Only hold on to scanout buffers in next_fb and current_fb
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
which completes in the background. Those are referenced from the scanout
buffers themselves to ensure the source buffers live just as long.

8f268f2930 backends/native: Keep general direction when crossing monitors
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.

c390f70edc backend: Set up and use ownership chains
This means objects have an owner, where the chain eventually always
leads to a MetaContext. This also means that all objects can find their
way to other object instances via the chain, instead of scattered global
singletons.

This is a squashed commit originally containing the following:

cursor-tracker: Don't get backend from singleton

idle-manager: Don't get backend from singleton

input-device: Pass pointer to backend during construction

The backend is needed during construction to get the wacom database.

input-mapper: Pass backend when constructing

monitor: Don't get backend from singleton

monitor-manager: Get backend directly from monitor manager

remote: Get backend from manager class

For the remote desktop and screen cast implementations, replace getting
the backend from singletons with getting it via the manager classes.

launcher: Pass backend during construction

device-pool: Pass backend during construction

Instead of passing the (maybe null) launcher, pass the backend, and get
the launcher from there. That way we always have a way to some known
context from the device pool.

drm-buffer/gbm: Get backend via device pool

cursor-renderer: Get backend directly from renderer

input-device: Get backend getter

input-settings: Add backend construct property and getter

489bc65381 tests/utils: Add helper to flush the input thread
Add a helper function that ensures any queued virtual input events have
been flushed from the input thread. This works by posting a task to the
input thread, which will itself queue another callback back to the main
thread. Once the main thread callback is invoked, the flush call is
unblocked and the function returns. Upon this, any previously emitted
virtual input event should have already passed through the input thread
back into the main thread, however not necessarily fully processed.

For making sure it has been processed, one also have to make sure the
stage has been updated, e.g. via `meta_wait_for_paint()`.

8bc375005c kms/connector: Don't query the kernel twice when updating
On hotplug, the events we receive from the kernel are async, and
connectors in the kernel come and go as they please. In practice, this
means that calling drmModeGetConnector() twice more or less directly
after each other, there is no guarantee that the latter call will return
anything if the former did.

When updating the connector in response to hotplugs, we'd first update
the list of existing connectors, and following that, query each and
every one again for their current state, to update our internal
representation; only the former handled drmModeGetConnector() returning
NULL, meaning if unlucky, we'd end up doing a null pointer dereference
when trying to update the state.

Handle this by querying the kernel for the current connector state only
once per connector, updating the list of connectors and their
corresponding state at the same time.

Fixes the following crash:

1645171d4b seat/impl: Wait for pointer constraining when updating viewports
It is generally assumed here and there that the pointer at all point in
time is within some logical monitor, if there is any logical monitor to
be within.

With the input thread, this was for a short amount of time not reliable,
resulting in crashes in combination with hotplugging or suspend/resume,
where monitors come and go quickly.

What happens is that the pointer at first is within a logical monitor,
but when that logical monitor is removed, while the new monitor
viewports are handed to the input thread, the constraining happens
asynchronously, meaning there is a time between between the new
viewports are sent, and before clutter_seat_query_state() starts
reporting the constrained position.

If a new client mapped a maximized window during this short time frame,
we'd crash with

    #0 meta_window_place at ../src/core/place.c:883
    #1 place_window_if_needed at ../src/core/constraints.c:562
    #2 meta_window_constrain at ../src/core/constraints.c:310
    #3 meta_window_move_resize_internal at ../src/core/window.c:3869
    #4 meta_window_force_placement at ../src/core/window.c:2120

    #8 wl_closure_invoke at ../src/connection.c:1025
    #9 wl_client_connection_data at ../src/wayland-server.c:437

The fix for this is to make sure that the viewports are updated and
pointers constrained synchronously, i.e. the main thread will wait until
after the input thread is done constraining before continuing.

22d08501a8 cursor-renderer/native: Fix cursor sprite CRTC scale
The CRTC cursor sprite scale was incorrectly assumed to be always 1.0
when using the default not-scale-monitor-framebuffer mode. This is
harmless in most cases, as most clients provide HiDPI capable cursors,
but for the ones that didn't, we'd end up drawing their cursors
unscaled, when using the cursor planes.

a1d14a6176 cursor-renderer/native: Don't put opaque buffers in cursor plane
Cursor planes tend to be ARGB8888 and support no other format (ideally
we should not hard code this, but un-hard-coding that is for another
day), and if we put e.g. a XRGB8888 buffer in there, it'll either result
in the gbm_bo allocation failing (it doesn't allow USE_CURSOR with any
other format) or mode setting failing if using  dumb buffers directly.
In the former case, we'll fall back to OpenGL indefinitely, and in the
latter, we'll have failed mode sets as long as we try to set the invalid
cursor buffer as the cursor plane.

Change things to process all buffers that are not ARGB8888 using the
scale/rotate machinery we already have, turning XRGB8888 into ARGB8888.

5fa1a8cf42 backends/native: Send lores scroll in the middle of the detent
Some mice send a value slightly lower than 120 for some detents. The
current approach waits until a value of 120 is reached before sending a
low-resolution scroll event.

For example, the MX Master 3 sends a value of 112 in some detents:

              detent                   detent
    |                        |                       |
                        ^    ^                    ^
                        112  REL_WHEEL            224

As illustrated, only one event was sent but two were expected. However,
sending the low-resolution scroll event in the middle plus the existing
heuristics to reset the accumulator solve this issue:

              detent                   detent
    |                        |                       |
                ^          ^             ^          ^
                REL_WHEEL  112           REL_WHEEL  224

Send low-resolution scroll events in the middle of the detent to solve
this problem.

be4e6484ae render-device: Unmake the EGLContext after checking whether hw accelerated
When creating a render device, we create a temporary EGLContext where we
then query the `GL_RENDERER` string to check whether the renderer is any
of the known software renderers. After we're done, we destroy the
context and move on.

This should be fine as according to specification eglDestroyContext(),
with the context being actually destroyed a bit later when it's no
longer current, but mesa, when running RK3399 (Pinebook Pro), this
results in a crash in a future eglMakeCurrent():

  #0 in dri_unbind_context () at ../src/gallium/frontends/dri/dri_context.c:266
  #1 in driUnbindContext () at ../src/gallium/frontends/dri/dri_util.c:763

  #3 in eglMakeCurrent () at ../src/egl/main/eglapi.c:907
  ...

We can avoid this, however, by calling eglMakeCurrent() with
EGL_NO_CONTEXT on the EGLDisplay, prior to destroying, effectively
avoiding the crash, so lets do that.

58c3734d78 backend/native: Prepare render devices earlier than KMS
The type of render device used for a specific GPU affects the mode
setting backend that can be used, more specifically, when the render
device is an EGLStream based one, atomic mode setting isn't possible, as
page flipping is done via EGL, not via atomic mode setting commits.

Preparing the render devices before KMS devices means can make a more
informed decision whether to deny-list atomic mode setting for when
a certain GPU uses a EGLStream based render device instance.

This also means we need to translate mode setting devices to render node
devices when creating the render device itself, as doing it later when
creating the mode setting device is already too late.

9dda79b281 monitor-manager: Move gamma LUT manipulation API to MetaCrtc
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.

legitimately not have permission to use any GPUs, even if they exist.

0debb24e12 barriers: Make barriers fully part of the backend
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.

Crucially the following did not apply for `FLIPPED-90`

```

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

d985069542 kms/crtc: Don't report predicted gamma changes
We started to report resource changes using prediction when an update

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.

81b28a1d97 kms: Notify about privacy screen changes via predictions
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 years these things have improved, especially with the move to
graphene, so remove the old work around.

a49c4e188a backends/native: Use the PropTable to look up KMS values
We already look up all the metadata and values in the
MetaKmsConnectorPropTable so we can just use them instead of looking it
all up again.

4e3f3842a1 backends/native: Use MetaKmsPlaneRotation in plane updates
The ImplDeviceAtomic converts the MetaKmsPlaneRotation back to the
concrete KMS value. The MetaMonitorTransform is always directly
converted to a MetaKmsPlaneRotation.

981524c268 backends/native: Update PropTable on hotplug and remove parse callback
Updating the PropTable has the side effect that the parse callback now
also gets called on hotplug but it is used to initialize data. The parse
callbacks are moved to the read_state functions which are aware if this
is an initializing call or just an update.

9519a84967 backends/native: Define all KMS properties in PropTable we actually use
Currently those properties are looked up manually or fixed values are
used when they should be looked up. The following commits will actually
make use of this.

c9960850c8 tests/kms/render: Add direct scanout test case
This adds a minimalistic fullscreen direct scanout test case, that runs
on vkms. It doesn't use EGL, and it uses uninitialized memory, thus it
lacks any kind of implicit synchronization, but it does test that the
scanout selection paths are working.

What is tested is:

  * DMA buffer allocated using gbm on top of VKMS
  * Buffer passes a mode setting TEST_ONLY check
  * Paint is omitted
  * Correct buffer active in KMS after presentation

What isn't yet tested:

  * Implicit synchronization related behavior
  * Presented pixel content

a2ebd10f04 kms/crtc: Determine gamma support given the gamma length
The property doesn't necessarily exist when using drivers that doesn't
support atomic mode setting, and the way it worked will break night
light and other gamma related features. This makes things use the gamma
length; if it is higher than 0, it definitely supports it one way or the
other, i.e. GAMMA_LUT with the atomic backend, and drmModeCrtcSetGamma()
with the legacy/simple backend.

9001fa9717 kms/crtc: Always read the gamma state
It doesn't depend on whether the CRTC is active or not, so always read
it. This is also useful to know whether a CRTC supports gamma, before it
is being turned on, without relying on the existance of properties.
