Sometimes we hit a race on hot-plug where we try to read the KMS
resources and the EDID blob is not yet ready. This would normally
result in a ENOENT when retrieving the blob. Handle this by retrying
after 50 milliseconds after a hot-plug event. Do this up to 10 times,
and after that give up trying to get the EDID blob and continue with
best effort.

The function meta_monitor_manager_read_current_config() was renamed to
meta_monitor_manager_read_current_state() as it does not read any
configuration, but reads the current state as described by the backend.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The MetaMonitorMode referred to the mode of a CRTC, and with the future
introduction of a MetaMonitor, theh old name would be confusing.
Instead call it what it is.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of storing the logical monitors in an array and having users
either look up them in the array given an index or iterate using
indices, put it in a GList, and use GList iterators when iterating and
alternative API where array indices were previously used.
This allows for more liberty regarding the type of the logical monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Change meta_monitor_manager_get_logical_monitor_at() to use floats,
replace users of meta_monitor_manager_get_monitor_at_point() to use the
API that returns a logical monitor and remove the now unused function.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The method used for getting the current logical monitor (the monitor
where the pointer cursor is currently at) depends on the backend type,
so move that logic to the corresponding backends.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Let the backend initialize the cursor tracker, and change all call
sites to get the cursor tracker from the backend instead of from the
screen. It wasn't associated with the screen anyway, so the API was
missleading.

In preparation for further refactorizations, rename the MetaMonitorInfo

We need to do swap notifications asynchronously from flip events since
these might be processed during swap buffers if we are waiting for the
previous frame's flip to continue with the current.
This means that we might have more than one swap notification queued
to be delivered when the idle handler runs. In that case we must
deliver all notifications for which we've already seen a flip event.
Failing to do so means that if a new frame, that only swaps buffers on
such a swap notification backlogged Onscreen, is started, when later
we get its flip event, we'd notify only an old frame which would hit
this MetaStageNative's frame_cb() early exit:
if (global_frame_counter <= presented_frame_counter)
return;
and we'd never finish the new frame and thus clutter's master clock
would be waiting forever stuck.
https://bugzilla.gnome.org/show_bug.cgi?id=774557
When flush-swap-notify is already queued, we might end up trying to
requeue it, for example when handling flip callbacks inside
swap-buffers. Actually queuing it there is harmless, since old frames
will be discarded anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=774923
We might still end up in swap-buffer without the previous flip callback
having been invoked. This can happen if there are two monitors, and we
manage to draw before having all monitor flip callbacks invoked.

This commit adds for a new type of buffer being attached to a Wayland
surface: buffers from an EGLStream. These buffers behave very
differently from regular Wayland buffers; instead of each buffer
reperesenting an actual frame, the same buffer is attached over and
over again, and EGL API is used to switch the content of the OpenGL
texture associated with the buffer attached. It more or less
side-tracks the Wayland buffer handling.
It is implemented by creating a MetaWaylandEglStream object, dealing
with the EGLStream state. The lifetime of the MetaWaylandEglStream is
tied to the texture object (CoglTexture), which is referenced-counted
and owned by both the actors and the MetaWaylandBuffer.
When the buffer is reattached and committed, the EGLStream is triggered
to switch the content of the associated texture to the new content.
This means that one cannot keep old texture content around without
copying, so any feature relying on that will effectively be broken.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
This commit adds support for using a EGLDevice and EGLStreams for
rendering on top of KMS instead of gbm. It is disabled by default; to
enable it pass --enable-egl-device to configure.
By default gbm is first tried, and if it fails, the EGLDevice path is
tried. If both fails, mutter will terminate just as before.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
There is no way to pass any backend specific parameters to a
CoglFramebuffer until after it has been allocated by
cogl_framebuffer_allocate() (since this is where the winsys/platform
fields are initialized). This can make it hard to actually allocate
anything, if the platform depends on some backend specific data.
A proper solution would be to refactor the onscreens and framebuffers to
use a GObject based type system instead of the home baked Cogl one, but
that'll be left for another day. For now, allocate in two steps, one to
allocate the backend specific parts (MetaOnscreenNative), and one to
allocate the actual onscreen framebuffer (via
meta_onscreen_native_allocate()).
So far there is nothing that forces this separation, but in the future
there will, for example EGLDevice's need to know about the CRTC in
order to create the EGLSurface.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
A swap-buffers should never be issued when we are waiting for a flipped
callback, so instead of trying to handle a situation that sholud never
happen, warn instead.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
When a swap failed with EACCES (possibly due to VT switching), don't
mark the framebuffer as 'in use', so that it'll be cleaned up properly
and not set as current.

For when there is no gbm available, for example when using
EGLDevice/EGLStream's, just fall back to the OpenGL texture based

Drivers may be bad at guessing what is passed to eglGetDisplay, ending

Lets use a pbuffer surface as a dummy surface instead of a gbm based
one, so that we don't need to rely on the availability of gbm to create
a dummy surface when there is no need for it.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Separate gbm initialization from general renderer initialization. Do
this even though no other initialization is done for now; later there

In another step getting rid of the duplications introduced by Cogl,
use the equivalent GLib types where Cogl types previously used. While
CoglBool is not a typedef to gboolean, they are both typedefs to int,
and we already use GLib's TRUE/FALSE to set them.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Initialize the GError pointer used when creating the renderer. If an

Stylus configuration (stylus buttons, pressure) was handled
at the very high level, doing the button and pressure translations
right before sending these to wayland clients.
However, it makes more sense to store these settings into the
ClutterInputDeviceTool itself, and have clutter apply the config
at the lower level so 1) the settings actually apply desktop-wide,
not just in clients and 2) X11 and wayland may share similar
configuration paths. The settings are now just applied whenever
the tool enters proximity, in reaction to
ClutterDeviceManager::tool-changed.
This commit moves all handling of these two settings to
the clutter level, and removes the wayland-specific paths
https://bugzilla.gnome.org/show_bug.cgi?id=773779
Enabling edge scrolling before disabling two finger would result in
edge scrolling not actually being enabled because two finger is still
enabled at the time and we bail out.
This patch moves this logic to common code for both the native and X
backends and fixes it by ensuring that both settings are never set at
the same time and still re-checking if edge scrolling should be
enabled after two finger scrolling gets disabled.
We also simplify the code by not checking for supported/available
settings since the underlying devices will just reject those values
and there isn't anything we can do about it here. It's the UI's job to
only show supported/available settings to users.
https://bugzilla.gnome.org/show_bug.cgi?id=771744
Checking for supported methods isn't needed since libinput will just
error out and do nothing itself if a requested method isn't supported
and, in fact, this logic was preventing the enum values 0 from being
set.

commit e2bfaf0751 does this:
g_hash_table_insert (cards,
g_udev_device_get_name (parent_device),
g_steal_pointer (&parent_device));
The problem is the g_steal_pointer call may happen before the
g_udev_device_get_name call leading to a crash.
This commit does the get_name call on an earlier line
https://bugzilla.gnome.org/show_bug.cgi?id=771442
Right now we accept any character device that matches the glob card*.
That's fine, but we can be a little more specific by checking that

Despite g_udev_client_new taking a list of subsystems, it doesn't

Using the view's MetaMonitorInfo to find all the crtcs which should be
configured to display a given onscreen doesn't work unfortunately. The
association runs only the other way around, i.e. we need to go through
each crtc and find the ones corresponding to our monitor info.

If this isn't initialized and an idle watch gets instanced before
meta_idle_monitor_native_reset_idletime() gets called, that idle watch
would get triggered as soon as we hit the main loop.
This was causing gnome-session to go into idle mode at session start
thus making gnome-shell lock the screen.
In the past this bug was being masked by either logind emiting
session active signals or a stray input event making it through at
startup.

This isn't technically needed and, in fact, makes us default to
interlaced modes in some cases which isn't desirable.
Note that X doesn't account for these flags either for its mode
refresh rates.

As the m format specifier doesn't consume any arguments, the number
of varargs currently doesn't match the number of specifiers; the
failed transform may be relevant, so include it in the message
instead of removing the excess argument.
Some output devices only advertise their preferred mode even though
they're able to display others too. This means we can include some
common modes in each output's supported list.
This is particularly important for mirroring, since we can only mirror
outputs which are using the same resolution.

This signal allows interested parties to be notified of a new cursor
frame being painted regardless of whether it's being painted by the

Switch to the output naming logic used by the X server's modesetting
driver which, in particular, uses drmModeConnector's connector_type_id
instead of connector_id.
The kernel generates new connector_id's every time there are changes
which means we can't identify the same monitor on the same connector
after an hardware hotplug. Switching to connector_type_id fixes this.

We can only honor this properly in the MUTTER_STAGE_VIEWS=1 case. When using
the legacy view, software implemented transforms are only exposed if there is
only one output, as we can only transform the entire stage there.

The texture is only created if the view is transformed at the software level,
otherwise the texture is NULL, and rendering happens on the onscreen.

The offscreen is given through the ::back-buffer property, the ClutterStageView
will set up the the CoglPipeline used to render it back to the "onscreen"
framebuffer.
The pipeline can be altered through the setup_pipeline() vfunc, so ClutterStageView
implementations can alter the default behavior of blitting from offscreen to
onscreen with no transformations.
All getters of "the framebuffer" that were expecting to get an onscreen have
been updated to call the right clutter_stage_view_get_onscreen() function.
https://bugzilla.gnome.org/show_bug.cgi?id=745079
The call to _cogl_framebuffer_winsys_update_size() results in no-op here,
as the framebuffer has already the right size when rebuilding the views.

Those will need a separate treatment from the modes that we eventually
support through "software", so split those into a separate enum so we
can can do the right thing when applying the configuration.
Also, add a helper function that returns the transform that the software
fallbacks should perform, which should be "normal" if the rotation is
already handled via hw.
The function applying the configuration has been modified to always set
a HW rotation mode (even if normal), when we come to support SW rotation
modes, we'll be relying on a normal transformation, so it will be
necessary to have mixed HW/SW managed transforms.
https://bugzilla.gnome.org/show_bug.cgi?id=745079
The scale will have been set to 1 no matter what when initializing the
MetaOutput since it at the time didn't have an CRTC assigned to it.
Now, when we assign the CRTC to the output, we need to update the scale.

Support changing the mouse and trackball acceleration profile. This
makes it possible to for example disable pointer acceleration by
choosing the 'flat' profile.
This adds an optional dependency on gudev. Gudev is used by the X11
backend to detect whether a device is a mouse or not. Without gudev
support, the accel profile settings has have effect for mouse devices.
Trackball still uses the "strstr" approach, since udev doesn't support
tagging devices as trackball devices yet.

Add support for setting edge-scrolling separately from two-finger
scrolling. We now have 2 separate boolean settings for those, with the
Mouse panel in gnome-control-center allowing to set only one of those at
a time, but nothing precludes both being set in the configuration.
We need to handle:
- two-finger-scrolling-enabled and edge-scrolling-enabled settings both
being set.
- those 2 settings being change out-of-order
- two-finger-scrolling being set on a device that doesn't support it
- edge-scrolling-enabled on a device that doesn't support it
And the combinations of one touchpad supporting just one of edge
scrolling and two-finger scrolling and another vice-versa.

They are already effectively interchangeable so this should reduce
pointless casts.
Just like in GDK though, we need to keep the old definition for
instrospection to be able to include the struct's fields.
By creating a pending gbm/EGL surface pair, only setting it on
swap-buffers, we would draw onto a buffer on the old surface, then swap
the buffer from the new surface, causing the first frame after a
hot-plug always having no content.
This was in the past not very noticable since some non-deterministic but
frequent side effect in gnome-shell caused hot-plugging to always render
two new frames, but after "Introduce regional stage rendering", this
side effect did not occur as often, thus making it more visible.
This commit updates the current gbm/EGL surface pair before painting a
frame, so that when the frame is painted, the surface with the correct
size is used and the buffer from correct surface is swapped.

CoglFrameInfo is a frame info container associated with a single
onscreen framebuffer. The clutter stage will eventually support drawing
a stage frame with multiple onscreen framebuffers, thus needs its own
frame info container.
This patch introduces a new stage signal 'presented' and a accompaning
ClutterFrameInfo and adapts the stage windows and past onscreen frame
callbacks users to use the signal and new info container.

Make the cogl vfunc functions have names that are globally
discoverable. Calling the same function in every backend the same name
causes code navigation tools to not function properly. Rename the

https://bugzilla.gnome.org/show_bug.cgi?id=768976
Add support for drawing a stage using multiple framebuffers each making
up one part of the stage. This works by the stage backend
(ClutterStageWindow) providing a list of views which will be for
splitting up the stage in different regions.
A view layout, for now, is a set of rectangles. The stage window (i.e.
stage "backend" will use this information when drawing a frame, using
one framebuffer for each view. The scene graph is adapted to explictly
take a view when painting the stage. It will use this view, its
assigned framebuffer and layout to offset and clip the drawing
accordingly.
This effectively removes any notion of "stage framebuffer", since each
stage now may consist of multiple framebuffers. Therefore, API
involving this has been deprecated and made no-ops; namely
clutter_stage_ensure_context(). Callers are now assumed to either
always use a framebuffer reference explicitly, or push/pop the
framebuffer of a given view where the code has not yet changed to use
the explicit-buffer-using cogl API.
Currently only the nested X11 backend supports this mode fully, and the
per view framebuffers are all offscreen. Upon frame completion, it'll
blit each view's framebuffer onto the onscreen framebuffer before
swapping.
Other backends (X11 CM and native/KMS) are adapted to manage a
full-stage view. The X11 CM backend will continue to use this method,
while the native/KMS backend will be adopted to use multiple view
drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=768976
In preperation for having allowing drawing onto multiple onscreen
framebuffers, move the onscreen framebuffer handling to the
corresponding winsys dependent backends.
Currently the onscreen framebuffer is still accessed, but, as can seen
by the usage of "legacy" in the accessor name, it should be considered
the legacy method. Eventually only the X11 Compositing Manager backend
will make use of the legacy single onscreen framebuffer API.
https://bugzilla.gnome.org/show_bug.cgi?id=768976
Split the stage window implementations into three separate objects: one
for X11 as a compositing manager, one for X11 running as a nested
Wayland compositor, and one for running with the native backend.
The new stage window implementations are only thin shells; this is in
preparation for making the stage windows behave more differently.

Move the KMS interaction from cogl into mutter, where most of the other

via the different cogl objects.

Sadly, GLib's autoptr cleanup macros cannot be detected by the C
