Previously we assumed that cursor planes occluded nothing and would
always be blended, but overlay and scanout planes would always occlude
what's behind them. This is not actually true, as we can support alpha
blending on any kind of plane type now.
Remove the special case, which might hopefully fix some weird display
issues along the way. (Noticed by inspection.)

We used to use planes_region for the output regions which were being
displayed on hardware planes; before we grew zpos awareness, we couldn't
have any planes overlapping with each other, since the ordering would be
undefined.
Since the zpos awareness though, this region is unused, so we can just
remove it.

The opaque region is used to determine where the views underneath the current
view must be drawn. If the opaque is not clipped, then the area that is part of
the opaque region but not part of the scissor area is not drawn at all.

Subsurfaces inherit the scissor region from the parent surface. Currently
the region is updated at the end of weston_view_update_transform(). As a
result, the old region is used to clip the transform.boundingbox of the
subsurface.
Change the order to update the scissor region after the transform.matrix is
updated but before it is used.

After some changes in the exposay layout, the outer padding makes
no sense anymore. It was used to avoid the panel to get overlapped
by the exposay surfaces and to keep distance from the borders
of the window.
Currently, the exposay is centralized and the panel cannot get
overlapped. The outer padding just creates unnecessary unused
space, what makes exposay's surfaces smaller.
Delete outer padding from struct exposay_output.

We've been using an inner border of fixed size (80px), but this
is dangerous. If you have too many open applications or a small
window, the surface size computed will be negative, crashing
the exposay: "error: weston_view transformation not invertible".
Also, it creates a lot of unnecessary space, making the exposay
unusable when we have a small window or many applications open.
Make inner border to be 10% of surface size and surface size to
be 90% of its original size, avoiding the crashes and making it
more visually pleasant.

Commit "desktop-shell: make get_output_work_area() global" allowed
the usage of get_output_work_area() in exposay. This is necessary to
avoid overlapping the panel when rendering exposay's surfaces.
Use get_output_work_area() to not take into account the panel size,
instead of considering that the whole screen is available to
render exposay's surfaces.
Signed-off-by: Leandro Ribeiro <leandrohr@riseup.net>
get_output_work_area() can be used by exposay to know the free space
where it can render its surfaces, what avoids overlapping the panel.
Currently this function is declared as static in
desktop-shell/shell.c, so it cannot be used by exposay.
Remove static from get_output_work_area() and add it to shell.h
so it can be used by exposay as well.

Pipewire doesn't need to wait for any hardware. The finish_frame() callback is
just artifically delayed to generate the desired framerate.
So when the DPMS level changes, we can just call finish_frame() immediately if
necessary and cancel the timer.
Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
Initially finish_frame() was never called in drm_output_update_complete() for
'dpms_off_pending = true'. This is wrong for repaint_status ==
REPAINT_AWAITING_COMPLETION and that was fixed in
68d49d772c ("compositor-drm: run finish_frame when
dpms is turned off in update_complete").
However finish_frame() may now be called for repaint_status !=
REPAINT_AWAITING_COMPLETION, which is not allowed and results in a failed
assertion.
Fix this by checking dpms and repaint_status unconditionally.

It seem that we skipped to put back in TEXT mode the tty, in case a DRM
device node wasn't present at that time, or it isn't present at all. This
orders the destroy part correctly as to handle that case as well.
As a side effect, as the tty will still be set to GRAPHICS mode we will
require a manual change of the tty number, which might be not possible
on all systems. Properly putting back the tty to TEXT mode should avoid
that, and allows to re-use the same tty no in case the DRM device has
been created at a later point in time.

Allow to disable GBM modifiers at runtime using the environment variable
WESTON_DISABLE_GBM_MODIFIERS.
This can be useful for debugging or when modifiers cause issues, e.g. in
case modifiers use higher memory bandwidth and hence impose a lower

The opaque region of a weston view is updated only if the alpha value is 1
and the transform matrix is of type WESTON_MATRIX_TRANSFORM_TRANSLATE.
While using ivi-shell, opaque region is never updated, as we are performing
scaling operations to the view transform matrix, even when the scaling
factor is 1 and thereby changing the type to WESTON_MATRIX_TRANSFORM_SCALE.
Perform scaling of the view transformation matrix only when the scaling
factor is non-zero.

If a surface is not visible, then is does not matter if the view is on multiple
outputs. It will be skipped anyways when the output is rendered.
So check first if the surface is acually visible on the output before doing any
checks that might force rendering. This avoids unnecessary rendering.

When dissociating a universal plane from a crtc, we currently don't
reset the current state of the plane (plane->state_cur). When attempting
to use this plane in the future, we can run into invalid memory accesses
due to left over associations with potentially freed drm backend
objects. This commit resets the state of the scanout and cursor
universal planes associated with a crtc.
The following scenario exhibits the problem:
1. Start a (fullscreen) client that is suitable for and assigned to
the scanout plane. The plane's state_cur->output value is set.
2. Unplug the monitor: the scanout plane is "released" but still
maintains the state_cur->output association.
3. Replug the monitor: the plane is deemed unavailable due to an
existing, albeit invalid, state_cur->output value. Note the memory
errors trying to access the drm_output which was freed at step (2).

compositor_accumulate_damage() is called for each output during repaint.
The DRM backend will only set keep_buffer for the surfaces that are visible on
the current output. So a buffer_ref is released that may still be needed. When
the output that shows the surface is repainted, the buffer_ref is gone and the
surface cannot be put on a plane.
Ignore all surfaces that are not visible on the current output to avoid this.

Currently the debug output for 'drm-backend' can be confusing. In the output of
debug_scene_view_print() views may be listed as 'not opaque' but later, during
plane assignment, other views underneath such a view is reported as 'occluded on
our output'.
This happens because weston_view_is_opaque() has some extra checks to determine
if a view is fully opaque, such as 'is_opaque' provided by the renderer for
formats that have no alpha channel.
Use weston_view_is_opaque() in debug_scene_view_print() as well to get more
accurate results.

kiosk-shell is fullscreen shell for apps that use the xdg-shell
protocol. The goal is to make life easier for people shipping embedded
devices with simple fullscreen shell requirements, and reduce the
proliferation of desktop-shell hacks.
Top level surfaces are made fullscreen, whereas dialogs are placed on
top in the center of the output and retain their natural sizes. Dialogs
can be moved and (un)maximized, but resizing is currently not supported.
An app can be directed to a particular output by populating the
"app-ids" field with the app's XDG app id, in the relevant
"[output]" section in the weston config file.

In order to run DRM-backend tests, a DRM-device is needed. As we
do not necessarily have control of the hardware that is going to
run our tests in GitLab CI, DRM-backend tests were being skipped.
This patch add support to run the tests using VKMS (virtual KMS).
To achieve this, virtualization is needed, as we need to run a
