This reverts commit 55bf6b5046.
This accidentally removed things that should have stayed - libseat
can still use the logind API, even if weston doesn't directly use
it.
Note that the logind-launcher does not actually build anymore
because breaking changes landed before this revert.
Since we're removing it again right away, I've not taken care to

While the --backend parameter looks like it takes a file name, it really
is selected from a list of supported strings that are then funneled
through a translation to enum weston_compositor_backend [1].
Because all backend parameters are of the form "...-backend.so", and
writing "--backend=...-backend.so" is boring, allow the --backend option
to match the backend name without "-backend.so" suffix instead.
For example, this allows to use "--backend=headless" instead of
"--backend=headless-backend.so".
Update help text and documentation. Keep the old way working for
backwards compatibility.

entirely as we have enabled warning as error in the doxygen

By default meson werror build option is not enabled, so users can still

All these Doxygen configuration directives raise a deprecation warning

Since we have WARN_AS_ERROR = YES, this causes the build to fail.

I have checked the differences by first building from scratch without
this patch, and then building from scratch with this patch, and
in the latter builddir checking
$ diff -ru -x '*.md5' -x '*.pdf' ~/tmp/weston-doc-before doc

Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.
Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.
I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.
Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

When using the libseat launcher, there is one more detail to take care:
stop libseat from managing the VT.
A normal user does not have permissions to manage a VT, so launching
would just fail. In this use case you also do not want to be managing

associated with the VT.

Add VGEM to the Linux image that runs in the CI. There are tests that we
plan to add in the future that need this.
This brings a complication, as we already have VKMS in the image. The
order in which DRM devices are loaded is not always the same, so the
node they receive is non-deterministic. Until now we were sure that VKMS
(the virtual device we use to run the DRM-backend tests in the CI) would
be in "/dev/dri/card0", but now we can't be sure. To deal with this
problem we find the node of each device using a one-liner shell script.
This commit also updates the documentation section that describes
specificities of DRM-backend tests in our test suite.

The color scheme is neutral, trying to avoid a Christmas tree effect.

This used a cargo-culted form of the ACTION check. Kernel is allowed to
invent new ACTIONs and IIRC there are already actions like bind and
unbind.
Udev events before rule processing always start with a clean property
list. This means that if you only match ACTION==add to add some value to
the event, then that value will not be present for ACTION==bind. Udev
event consumers do not accumulate values, so inconsistent value setting
may confuse them.
Therefore one needs to match ACTION!=remove, not ACTION==add|change, to
keep the device properties consistent for every event. It doesn't hurt
to set them on remove either, but it's a habit to try to avoid
processing when not strictly needed.

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.

With this patch we add support to run DRM-backend tests locally
in the test suite. For now this won't work in the CI, as there
are no cards available. But the plan is to achieve this by using
VKMS (virtual KMS) in the future.
To run DRM-backend tests locally, first of all the user has to
set the environment variable WESTON_TEST_SUITE_DRM_DEVICE to
'card0', 'card1' or any other device where he wants to run
the tests. Also, for now it only works if it is run as root,
but in the future this problem will be solved.
The tests will run on a non-default seat. The reason for that
is that we want to avoid opening input devices unnecessarily.
Also, since DRM-backend usage requires gaining DRM master status
on a DRM KMS device, nothing else must be using the device at
the same time. To achieve this we use a lock to run the
DRM-backend tests sequentially.

The only reason why we have both weston_compositor_tear_down() and
weston_compositor_destroy() is that the only we had to destroy
the log context was keeping weston_compositor alive and calling
weston_log_ctx_compositor_destroy().
After commit "weston-log: replace weston_log_ctx_compositor_destroy()
by weston_log_ctx_destroy()", it's not necessary to keep a zombie
weston_compositor just to be able to call
weston_log_ctx_compositor_destroy().

The function weston_log_ctx_compositor_destroy(), which destroys struct
weston_log_context, takes weston_compositor as argument. We may have a
weston_log_context unlinked from a weston_compositor and currently there
is no way to destroy it.
Add function weston_log_ctx_destroy(), what makes the destruction of
weston_log_context independent of weston_compositor.
With this change, one could destroy a weston_compositor and keep the
related weston_log_context (since now weston_log_context can be destroyed
without the need of a weston_compositor). But if weston_compositor gets
destroyed it's also necessary to destroy weston_log_context::global,
as the debug protocol depends on the compositor. So a listener has been
added to the destroy signal of weston_compositor.

When we were designing the libweston output API, I wrote a design document
as a Phabricator wiki page. Phabricator is no longer accessible so that
information needs to be migrated to a new place. Here I am converting most of
it into libweston Sphinx documentation, particularly pulling in the sequence
diagrams I drew. This should help people understand how libweston output
configuration works.
The diagrams are committed as both MSC source files and rendered PNG files. I
did not bother tinkering with the build to run mscgen automatically and then
with the CI images to install the tool.
The Sphinx configuration need numref explicitly enabled so that figures are
automatically numbered and can be referenced by their number rather than their
whole caption text(!).
The document structure is changed a little better flowing with Output
Management being the overview page and the Heads and Outputs being the API
pages.
First I wrote the struct weston_output and weston_head descriptions in Doxygen
comments in libweston.h, but then in the API page that text would have been
buried somewhere towards the end of the page. So I put that text in ReST
instead where it comes as first on the pages as it should. The doc for the
structs only contain a link to the top of the page. Yes, the comment style in
libweston.h is a little broken. If I left the asterisk there it would show up
as a bullet point in Sphinx. OTOH putting everything from \rst in a single line
did not produce anything.
Because Sphinx cannot look in two places, the images need to be copied into the
build dir too.
