Pekka Paalanen ae12b9596d tests: add yuv-buffer test
This adds a test to ensure that the wl_shm formats YUV420, NV12 and YUYV
are decoded and converted to RGB correctly in GL-renderer.

The test deliberately uses a 256 x 256 test image so that effects from
width vs. pitch vs. stride cannot be observed, and row padding is zero.
Also padding between planes is zero. Attempting to use a test image with
less "round" dimensions lead to stride mismatch in GL-renderer, likely
due to GL_UNPACK_ALIGNMENT being left at value 4. It is unclear if YUV
wl_shm buffers' row stride needs to be aligned to 4 bytes or not, so I
did not pursue fixing it. GL-renderer seems to be confusing width, pitch
and stride even further, and not e.g. allow padding with ARGB buffers.
See also: https://gitlab.freedesktop.org/wayland/weston/-/issues/354

Furthermore, the test arranges so that each 2x2 pixel block has the same
color. This avoids having to consider chroma siting when sub-sampling.
This way all the test cases can use the same reference image.

Pekka Paalanen 593d5af43a gl-renderer: require GL_EXT_unpack_subimage
Require GL_EXT_unpack_subimage unconditionally in GL-renderer. Without
this extension, it would take considerable effort in GL-renderer to
handle correctly images that contain row padding, either as a temporary
copy to remove padding or doing SubImage updates row by row.

I would guess that this path has gone long completely untested, and if
it was exercised, the rows never had padding thanks to 32-bit pixel
formats. Instead of writing tests to poke the corner cases and fixing
it, remove it.

This will make it easier to fix other problems in GL-renderer in this
area in the future - one less path to consider and many restrictions in
GL API gone.

Pekka Paalanen 4e9f4d0474 launcher-direct: allow non-root on non-seat0
If the launcher is told to use a non-default seat (not seat0), there
will not be a VT or tty to set up. VT/tty setup requires privileges.

This patch allows a non-root user to use launcher-direct, provided that
the seat is not the default. There is still the problem of opening DRM
and input devices, which is left for the user to solve.

This mode of operation is useful for developers who can set up a
secondary seat on their machine. You can run Weston/DRM from a terminal
window by pointing it to a non-default seat. You have to arrange a
DRM device by having an extra unused graphics card in the machine. You
also need dedicated input devices. Both the DRM device and the input
devices must be assigned to the secondary seat and device file
permissions adjusted so that they can be opened.

Doing so is an obvious security risk, as input could easily be
eavesdropped.

Marius Vlad e825fe389e libweston/libinput-device: Enable/Set pointer capabilities only on pointer movement
Some panels advertise both pointer/touch capabilities but without having
real capability of driving a cursor (they're basically touch panels) and
use USB as a communication tunnel to transfer/send out input events.

As we can't really tell if they're fake or not, only advertise to
clients pointer capabilities if we detect movement on the cursor/pointer.

We handle it at lower level as that allows to handle the case where
removal of a real pointer should also remove the cursor from being
displayed on the screen.

but in case we have different plug-ins or multiple remote

Marius Vlad 092130c4bf kiosk-shell: Keep track of seats created and destroy them at end
kiosk_shell_destroy() will free up weston_desktop, but still keeping
listeners set-up (keyboard/seat/caps), which will fire
when the the compositor is stopped/shutdown by clients still connected.

This patch maintains a list of seats and uses it to remove any listeners
when calling kiosk_shell_destroy(). desktop-shell and ivi-shell do not
appear to be using weston_desktop_destroy() in their respective destroy
parts.

This avoids an illegal access happening when calling one of the

which is also user of libweston. So rename screenshot protocol
function to weston_screenshooter_take_shot() to avoid the conflict.

Leandro Ribeiro 32a5acde5b tests: add mechanism to change Weston's behavior when running certain tests
There are some specific cases in which we need Weston to
behave differently when running in the test suite. This
adds a new API to allow the tests to select these behaviors.

For instance, in the DRM backend we plan to add a writeback
connector screenshooter. In case it fails for some
reason, it should fallback to the renderer screenshooter
that all other backends use. But if we add a test to
ensure the correctness of the writeback screenshooter,
we don't want it to fallback to the renderer one, we
want it to fail. With this new API we can choose to
disable the fallback behavior specifically for this test.

Tanmay Shah 8ef3ce5c67 clients: Fix shell background image setting.
If weston.ini is not setting background-image path,
then desktop-shell sets ${DATDIR}/weston/pattern.png
as background. However in this case  width and height
is set to 1 during background config and is being
scaled to avoid allocation of buffer.

This behavior is not right. Along with background-image
path, we should also check if background-color is set.
If background color is set, then only scale 1x1 buffer.

This would allow to set pattern.png as default wallpaper
of weston correctly, if background-color is also not set

current comment. Using Weston with rdp-backend directly as well as
using the screen-share plug-in allowed to reconnect just fine. Hence
release the Weston seat properly using weston_seat_release and free
the seat structure. This also avoids mouse pointers displayed for
every RDP connection.

David Fort e3f447eee8 rdp-backend: require FreeRDP >= 2.2 to remove all the version hacks
The stable FreeRDP 2.x branch has been released, so let's rely on that maintained
version and drop all the hacks for older versions. That makes the code and build
cleaner.

Convert ivi-shell-app-test.c to use `weston_ini_setup`. It also removes
the pre-made weston.ini and all the related code in the meson files.

Leandro Ribeiro 96bef0517e drm-backend: add support for writeback connectors
Recognize writeback connectors and add 'struct drm_writeback'
objects in order to store them.

These objects are created and stored in a list by the time
that DRM-backend is initialized. This list is updated if a
writeback connector dynamically appears or is disconnected.

Leandro Ribeiro 7243022b38 drm-backend: add function drm_backend_add_connector() to create drm_head for connectors that appear
Instead of directly creating heads for the connectors in functions
drm_backend_create_heads() and drm_backend_update_connectors(),
add drm_backend_add_connector() that will handle this.

This split makes the code look better and will also make our lives
easier when we introduce writeback connectors.

To deal with appearing/disappearing connectors we have the
function drm_backend_update_heads(). Rename it to
drm_backend_update_connectors(), as it is more in line with
what it does.

Leandro Ribeiro 4a5b67a5db drm-backend: update description of drm_head_create() and drm_head_update_info()
In case of success, drm_head_create() and drm_head_update_info()
take ownership of a connector. As this is an important
information, update the description of these functions
to include this.
