In some circumstances (like system load) we seem to be racing with the
threads fontconfig creates and the resource release happening inside
cleanup_after_cairo(), and we would still find a cached entry holding a
font map reference while we are on the compositor exit path --
which happens in cleanup_after_cairo() when calling
cairo_debug_reset_static_data().
This was introduced with commit 823580e070, 'backend-headless: fully
release pango and fontconfig', as a way to have a clean memory leak
report, but due to the fact we can't influence how libraries manage
their threads, the solution (for now at least) would be to just remove
it entirely.
Running it at the end in the test itself, or before calling exit(2),
while it does narrow the window, it still exhibits the cairo crash assert
related to having cached entries in that font map hash table.

Since 2d70bdfdcd "drm-backend: add support
to output capture writeback source", the DRM-backend was broken for KMS
devices that do not support the atomic API. This fixes that.
We don't support writeback screenshots without atomic modeset support.
So for such devices, we never update the output capture info
(weston_output_update_capture_info()) for the writeback source.
The function that we use to pull writeback tasks
(weston_output_pull_capture_task()) asserts that the capture providers
(renderers, DRM-backend) did not forget to update the capture info
(size/format) if something changed. But as we've never updated the
capture info for such devices, it is zeroed, leading to an assert hit.
With this patch we only pull the capture task for KMS devices that
support the atomic API.
Signed-off-by: Leandro Ribeiro <leandro.ribeiro@collabora.com>
In 2d70bdfdcd "drm-backend: add support to
output capture writeback source" we've ensured that disable_planes
should be false in order to support writeback capture tasks.
But this was wrong; disable_planes is transient (it is true when
there's some sort of content recording happening), and we enable/disable
that during compositor's lifetime.
This is dangerous and may result in a crash. Imagine the following
sequence:
1. screen recording starts, disable_planes is set to true.
2. for whatever reason the output size changes, and we end up
not updating capture info because we think that writeback is not
supported by the device.
3. screen recording stops, disable_planes is set to false.
4. user tries to take a writeback screenshot, and the
DRM-backend will pull a writeback capture task with
weston_output_pull_capture_task().
5. this function has an assert to ensure that the DRM-backend
did not forget to update the capture info, and we hit that
assert.
With this patch we drop disable_planes being false as a condition to
support writeback. So now we keep the capture info up-to-date even when
screen recording is happening, and we gracefully fail writeback tasks.

This adds three new helpers: one to iterate over all debug scopes
created/added and other two are for simpler getters for the scope name
and the description.
Included with this change is also a simple test to retrieve them.
This is an alternative to using the debug scope list advertised when
using the weston-debug private extension. libweston users can use this
directly to know which scopes they can subscribe to, and there's no need
to have a client implementation for the weston-debug protocol.

We log the reasons why the fb of a certain view was not placed in an
overlay plane and use that for debug purposes. With these reasons we
also decide if the scanout tranche should be included on the dma-buf
feedback or not. For instance:
1. If the reason is the incompatibility between the format/modifier
pair of the fb and those supported by the KMS device, the scanout
tranche is added and feedback is re-sent (so that the client can
re-allocate with parameters that makes it eligible for direct
scanout).
2. If the reason is because we have no overlay planes available, the
scanout tranche is useless. So the scanout tranche is removed and
the feedback re-sent (so that clients can re-allocate with
parameters optimal for the render device).
Also, when we detect that a view is eligible for direct scanout, we
don't even consider sending new feedback, as our interpretation of the
dma-buf feedback spec was that we should avoid bothering clients with
new feedback when they are already hitting direct scanout.
After some discussions and clarifications regarding the spec, we've
realized that Weston should start to also include the scanout tranche
even when the compositor is able to place client's content on overlay
planes. Basically, because this gives a chance for clients to
re-allocate with the proper parameters (not only format/modifier pair,
but also the target_device and the flags) from the scanout tranche. In
this patch we start doing this.

renderbuffers must be destroyed before the output can be destroyed.
Also, weston_renderbuffer_unref() is not called when the buffer is released
because buffer->output is now NULL, so the renderbuffer would be leaked.
So just unref the renderbuffer immediately. Set it to NULL to avoid unreffing it
again should wayland_output_destroy_shm_buffers() be called again before the
buffer is released. This can happen during an xdg-shell resize.

The state does not own the fd. This is usually not a problem, because the
in_fence_fd of the state is assigned during drm_assign_planes() and then
immediately used in drm_repaint_flush(). It cannot be closed in-between.
However, in the fallback path in drm_output_start_repaint_loop(), the state is
duplicated. At this point in time, the in_fence_fd may be invalid because it was
replaced in a new commit of the corresponding surface.
The plane state was already committed to the kernel when it is copied, so the
fence is no longer needed. So just clear it.

With multiple DRM devices, the state for one device may be empty during
repaint_flush(). This can happen for example if an output of one device triggers
the repaint and there are no screens attached to the other device and therefore
no active outputs.

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().

Weston uses a cached drm_fb when a view is shown multiple times. If the view is

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

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().

Let's create a family of coordinate vector structures for coordinate

This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
