Add meta-kms and meta-monitor-manager-kms listener for the udev
device-removed signal and on this signal update the device state /
re-enumerate the monitors, so that the monitors properly get updated
to disconnected state on GPU removal.
We really should also have meta-backend-native remove the GPU itself
from our list of GPU objects. But that is more involved, see:
https://gitlab.gnome.org/GNOME/mutter/issues/710
This commit at least gets us to a point where we properly update the
list of monitors when a GPU gets unplugged; and where we no longer
crash the first time the user changes the monitor configuration after
a GPU was unplugged.
Specifically before this commit we would hit the first g_error () in
meta_renderer_native_create_view () as soon as some monitor
(re)configuration is done after a GPU was unplugged.

drmModeGetConnector may fail and return NULL, this may happen when
a connector is removed underneath us (which can happen with e.g.
DP MST or GPU hot unplug).
Deal with this by skipping the connector when enumerating and by
assuming it is disconnected when checking its connection state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
drmModeGetCrtc may fail and return NULL. This will trigger when
meta_kms_crtc_update_state gets called from meta_kms_update_states_sync
after a GPU has been unplugged leading to a NULL pointer deref causing
a crash.
This commit fixes this by checking for NULL and clearing the current_state
when NULL is returned.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
Before this commit meta_kms_crtc_read_state was overwriting the
entire MetaKmsCrtcState struct stored in crtc->current_state including
the gamma (sub)struct.
This effectively zero-s the gamma struct each time before calling
read_gamma_state, setting the pointers where the previous gamma values
were stored to NULL without freeing the memory. Luckily this zero-ing
also sets gamma.size to 0, causing read_gamma_state to re-alloc the
arrays on each meta_kms_crtc_update_state call. But this does mean that
were leaking the old gamma arrays on each meta_kms_crtc_update_state call.
This commit fixes this by making meta_kms_crtc_read_state only overwrite
the other values in the MetaKmsCrtcState struct and leaving the gamma
sub-struct alone, this will make read_gamma_state correctly re-use the
gamma tables if the gamma table size is unchanged; or re-alloc them
(freeing the old ones) if the size has changed, fixing the memory leak.

The "device-added" signal should use g_cclosure_marshal_VOID__OBJECT not
g_cclosure_marshal_VOID__VOID.
Instead of fixing this manually, simply replace the closure function for
both signals with NULL, glib will then automatically set the correct
va_marshaller.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
Explicitly checking the dimensions of a mode to determine whether it
should be advertised or not fails for portrait style modes. Avoid this
by checking the area instead.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/722
Similar to gtk commit f507a790, this ensures that the valist variant of
the marshaller is used. From that commit's message:
```
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
```
https://gitlab.gnome.org/GNOME/mutter/merge_requests/697
By putting `NULL` as the C marshaller in `g_signal_new`, you
automatically get `g_cclosure_marshaller_generic`, which will try to
process its arguments and return value with the help of libffi and
GValue.
Using `glib-genmarshal` and valist_marshallers, we can prevent this so
that we need less instructions for each signal emission.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/697
This is important when using a touchscreen or stylus instead of a mouse
or touchpad. If the cursor only gets hidden and the focus stays the
same, the window will still send hover events to the UI element under
the cursor causing unexpected distractions while interacting with the
touchscreen.
Fix this by emitting a visibility-changed signal from the cursor tracker
which then triggers a focus surface sync and always set the focus
surface to NULL when it's synced while the cursor is hidden.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/448
Allow checking whether the pointer is visible without accessing the
trackers internal is_showing property. While we don't need this just yet
for reading the visibility inside meta-wayland-pointer, it's useful when
implementing the logic to remove Clutter's focus when the cursor goes
hidden later.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/448
COPY_MODE_PRIMARY has two paths, automatically chosen. For debugging purposes,
e.g. why is my DisplayLink screen slowing down the whole desktop, it will be
useful to know which copy path is taken. Debug prints are added to both when
the primary GPU copy succeeds the first time and when it fails the first time.
This is not the full truth, because theoretically the success/failure could
change every frame, but we don't want to spam the logs (even in debug mode)
every frame. In practise, it should be rare for the success or failure to ever
change. Hence, saying what happened on the first time is enough. This does
indicate if it ever changes even once, too, so we know if that unexpected thing
happens.
The debug prints are per secondary GPU since there could be several.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
When the preferred path META_SHARED_FRAMEBUFFER_COPY_MODE_SECONDARY_GPU cannot
be used, as is the case for e.g. DisplayLink devices which do not actually have
a GPU, try to use the primary GPU for the copying before falling back to
read-pixels which is a CPU copy.
When the primary GPU copy works, it should be a significant performance win
over the CPU copy by avoiding stalling libmutter for the duration.
This also renames META_SHARED_FRAMEBUFFER_COPY_MODE_* because the new names are
more accurate. While the secondary GPU copy is always a GPU copy, the primary
copy might be either a CPU or a GPU copy.

This bit of code was more or less duplicated in meta-renderer-native-gles3.c
and meta-wayland-dma-buf.c. Start consolidating the two implementations by
moving the *-gles3.c function into meta-egl.c and generalizing it so it could
also accommodate the meta-wayland-dma-buf.c usage.
The workaround in the *-gles3.c implementation is moved to the caller. It is
the caller's responsibility to check for the existence of the appropriate EGL
extensions.
Commit 6f59e4858e worked around the lack of
EGL_EXT_image_dma_buf_import_modifiers with the assumption that if the modifier
is linear, there is no need to pass it into EGL. The problem is that not
passing a modifier explicitly to EGL invokes implementation-defined behaviour,
so we should not have that workaround in meta-egl.c.
This patch intends to be pure refactoring, no behavioral changes. The one
change is the addition of g_assert to catch overwriting arbitrary memory.

Since 4cae9b5b11, and indirectly before that as well, the
MetaMonitorManager::power-save-mode-changed is emitted even
when the power save mode didn't actually change.
On Wayland, this causes a mode set and therefore a stuttering.
It became more proeminent with the transactional KMS code.
Only emit 'power-save-mode-changed' when the power save mode
actually changed.

We need to set XdndAware and XdndProxy on the stage window if running

We currently don't handle the lack of DRM_CLIENT_CAP_UNIVERSAL_PLANES
KMS capability. Fail constructing a device that can't handle this up
front, so later made assumptions, such as presence of a primary plane,
are actually valid.
If we want to support lack of said capability, the required planes need
to be emulated by a dummy MetaKmsPlane object.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/665
There were fallbacks in place in case IN_FORMATS didn't yield any usable
formats: the formats in the drmModePlane struct, and a hard coded array.
The lack of these fallbacks in place could result in a segfault as code
using the supported plane formats assumed there were at least something
in there.

The display name is being used by the monitor manager to expose to name
to the DBUS API.
It is being rebuilt each time, so instead build the displa yname once
for the monitor and keep it around, with an API to retrieve it, so that
we can reuse it in preparation of xdg-output v2 support.
https://gitlab.gnome.org/GNOME/mutter/issues/645
Simplify the call site a bit and make the native renderer know it should
queue mode reset itself when views have been rebuilt. This is done

We used to have wayland-specific paths for this in src/wayland, now we
have ClutterKeymap that we can rely on in order to do state tracking,
and can do this all on src/backend domain.
This accomodates the feature in common code, so will work on both
Wayland and X11.

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.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
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
of the new stage view watching API. It's design does not
rely on signals on purpose; the number of signals that would
be emitted would be too high, and would impact performance.
MetaStageWatch is an opaque structure outside of MetaStage.
This will be used by the screencast code to monitor a single

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.

When stage views are scaled with fractional scales, the cursor rectangle
won't be aligned with the physical pixel grid, making it potentially
blurry when positioned in between physical pixels. This can be avoided
by aligning the drawn rectangle to the physical pixel grid of the stage
view the cursor is located on.

Naming the keyboard accessibility settings `a11y_settings` wrongly
assumes there will never be any other type of accessibility settings.
Rename `a11y_settings` to `keyboard_a11y_settings` to avoid future
confusion.

MetaProfiler is not built when -Dprofiler=false, and that
breaks the build since MetaBackend unconditionally imports
and uses it.
Fix that by wrapping MetaProfiler in compile-time checks.

Extract the next buffer -logic into a new function. This allows to
simplify copy_shared_framebuffer_cpu () making it more readable.
This change is a pure refactoring, no functional changes.
