With some displays connect, disconnect, connect events can happen is a very
short amount of time. When this happens, the output global may already be
destroyed when a client tries to bind it. As a result, the client is
disconnected with a protocol error. See [1] for more details on the general
problem.
To mitigate this problem call wl_global_remove() first and call
wl_global_destroy() several seconds later. This is inspired by the
implementation for the same problem in wlroots.

Since the logic of pointer constraints assumes a valid view throughout, add a
signal to disable constraints when its current view is unmapped by Weston.
The assumption that a previously unmapped view is valid already leads to the
constraints code crashing. This can happen when attaching a NULL buffer to the
surface and commiting, which effectively unmaps the view with the side effect of
clearing the surface's input region, which is then assumed valid inside
maybe_warp_confined_pointer().

Currently, the surface destroy listener in pointer constraints is redundant,
since surface destruction already handles pointer constraints destruction (see

Add the --additional-devices parameter to Weston to add secondary drm devices
that will only be used as outputs, but not for rendering.
We can only fail the repaint for the entire backend, but not for single
devices. Thus, if one of the devices fail, we have to fail the repaint for the
entire backend.

Additional devices don't have a gbm device. Therefore, we cannot create gbm bos
for the cursor.
If the output device differs from the gbm device, fall back to the allocation of
a dumb buffer for the cursor on the output device. Update the cursor sprite with
a memcpy to the already mapped dumb buffer that belongs to the current cursor.

If the GBM bo was allocated on a different device than the device that is used
for the fb, we have to import the fd first and update the handle.
Use drmPrimeFDToHandle directly instead of using a gbm device for the scanout
device, since a gbm device would require a gbm implementation, which is often
not available for devices that only support scanout.

Weston uses a cached drm_fb when a view is shown multiple times. If the view is
shown on multiple outputs backed by different DRM devices, Weston returns the
cached drm_fb for the first device that was used for the import. This causes a
failure when adding the fb to the other device.
Use a list of all drm_fbs to cache the buf_fb per device, and check for the
device before reusing a drm_fb.

Now that struct weston_renderbuffer is refcounted, hold a reference for
renderbuffers on the pixman_output_state::renderbuffer_list. This allows
backends to destroy the renderer output state and release renderbuffer
references in any order without running into an assert().
To avoid breaking resizing, We also have to drop the renderbuffer list
during pixman_renderer_resize_output(). The backends have to create new
renderbuffers afterwards.

In IVI, there are several displays connected to a SoC. These displays
are just driven by differential pairs (LVDS, FPD-Link, GMSL) and powered
centrally. To reduce power comsumption when user inactivity timeout
happended on the display, there is a need to cut down pixel clock from
SoC. Then, if any input events happend on the display, it should become
active again.
Currently, controlling the compositor outputs doesn't happen independently
but rather globally, and outputs repaints are based on the compositor state
This is necessary to have an API that can force the power state of an
output to off via DPMS mode while all other compositor outputs remain
unaffected.

This is needed by drm_output_fini_egl() to be able to retrieve the
backend out of the drm_output on the shutdown path of the compositor.
Both the remoting plug-in and the pipewire plug-in are users of the
drm-virtual API and as such they would trigger a crash when shutting
down the compositor, as we're not setting up any backend whatsoever.

When a view is destroyed then the views of subsurfaces remain until the view
list is rebuilt for the next repaint.
During that time view->parent_view contains an invalid pointer and weston will
crash when it tries to access the view.
This happens for a surface with subsurfaces with views on two different outputs
with the ivi-shell:
When the surface is destroyed then the destroy handler of the ivi-shell
(shell_handle_surface_destroy()) may be called first. It will (indirectly)
destroy the view of the main surface with weston_view_destroy().
Next the surface destroy handler of the subsurfaces
(subsurface_handle_parent_destroy() is called. It will unmap the first view of
the subsurface. Here weston_surface_assign_output() is called which tries to
find the output of the second view and accesses the now invalid
view->parent_view in the process.
There are probably other ways to trigger similar crashes.
To avoid this, clear view->parent_view when the parent view is destroyed.

Starting with commit 4cde507be6 "backend-drm: fix plane sorting" the
plane list will have a descending order of the planes rather than ascending.
This reversed order had the side-effect of exposing the fact that we
don't set-up a plane index when creating the drm_plane using the DRM
virtual API. Without settting a plane index for that drm_plane we
effectively overwrite the plane index which has the 0 (zero) entry.
This wasn't an issue before commit 4cde507be6 "backend-drm: fix
plane sorting" as it seems we never picked up that plane index as
being a suitable one due to the fact that those were assigned to primary
planes, but after that commit, the cursor plane will be one getting
the 0 (zero) plane index.
Finally, this would trip over because we attempt to place a (cursor)
view on a primary plane (where it would've normally be a cursor
plane) and we end up with no framebuffer ref.
This is fixed trivially by assigning a plane index, different than the
ones already created by create_spirtes().
