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.

weston-test-runner.h includes wayland-util.h, therefore it needs
wayland-client. A partial dependency with just compile_args might have been
enough as it does not seem to use functions from wayland-util.c, but safer this
way and no harm.

The function weston_seat_init_keyboard makes sure that it has its
own reference to keymap, hence we can safely drop our reference.
This is similarly done in the X11 backend. It avoids leaking a
struct xkb_keymap per connection.

If a xdg_toplevel surface has a child (or multiple), the desktop shell
still allows to activate the parent. This can be problematic with
modal dialogs such as message boxes which then are hidden behind the
main window, which might be non-responsive to inputs at this this
point.
The protocol specifies set_parent as follows: "Set the 'parent' of
this surface. This surface should be stacked above the parent surface
and all other ancestor surfaces."
Track parent/child relationship in desktop-shell. Follow the protocol
recommendation and make sure the child stays stacked above the parent.

The RDP-backend is reporting a non-zero physical size
value, and there are some clients that get the resolution
in pixels directly from the physical size reported. This
leads to a resolution of 25.4 PPI (or 1px/1mm), which is too
small.
But there's no need for that. The physical size is reported
on enabling the output (in the case of RDP-backend we have
no information about it before this), and the resolution is
already set in this moment.
Report a zero physical size to compositor, what makes frontend
and clients use their default values and applications become
readable.

As dmabuf uses a different coordinate (top-left) system than OpenGL
(bottom-left) using both direct-display with the Y_INVERT dmabuf attrib
flag would result in the image being inverted (direct-display will

correctly). Notifies users that direct-display is in use.

Define the void pointer as pixman_region32_t instead of using it
directly.
Void pointers are used by generic API's so each user can define
a data type as needed. Not doing this is dangerous, since void
pointers implicitly cast from/to any pointer without giving
warnings. So we must define its type instead of using it directly
in a function call.

Remove member preferred_format from struct window and hardcode
ARGB32 pixel format for clients/window.
The member preferred_format was first added to allow hinting
of a preference for RGB565 when creating a window. But it is
not being used for a long time now. So it's safe to remove it
from the code, dropping support for RGB565 in clients/window.

wayland/ci-templates!18 allows the $HOME environment variable to
propagate into the execution of creating our build container. Without
that, buildah would leave us with an empty $HOME, which would have pip
install into /.local/bin.
As $HOME is preserved during our actual native builds, we would try to
find meson in /root/.local/bin and fail, since it had been stored to a
different path.
Bump the ci-templates dependency to one with the fix so we can build new
images again.

emissions. Later commit 2619bfe420 ("move frame_signal emission to
weston_output_repaint()") fixed this deficency along with moving the
location of the emission. Due to an issue of the location change, this
commit had to be reverted again.
This makes sure that the pixman as well as the GL renderer now also
emits the damage region instead of the Weston output.

When option-parser is confronted with a boolean option, have it write a
bool rather than treating the value as a pointer to an int32.
(lib)weston already heavily uses bool types internally, so this has the

existed as integer shadows of internal boolean variables.

This client contains driver-specific code to allocate buffers. However clients
shouldn't contain driver-specific code and should rely on e.g. mesa to allocate
buffers via standard interfaces.
Additionally, because the build system always tries to enable all features, some
experimental drivers and drivers that aren't included in amd64 distribution
packages were required. Users would need to manually disable some drivers.
Releasers would need to install libdrm from source (because the release process
forbids adding custom build flags). Dropping simple-dmabuf-drm simplifies both
building and releasing.
The functionality previously tested via simple-dmabuf-drm can now be tested with
simple-dmabuf-egl.

When the aspect-ratio-aware mode support was added to Weston, it was
done before the libdrm support was finalised and merged. Between it
being added to Weston and being merged, it changed to no longer provide
the offset for the bitmask.
Instead of using the mask and a compatible enum, if we update our
libdrm dependency, we can use the flag definitions directly from libdrm.
In 94e4068ba1, the libdrm dependency was bumped to 2.4.83, which
enabled us to remove a bunch of error-prone ifdefs by making atomic and
modifier support mandatory.
We determined in the discussion of !311 that it was safe to push the
dependency as high as 2.4.91, as that was what was available in major
distributions.
Bumping to 2.4.86 allows us to safely remove the ifdef and go with
upstream flags, as that was added in mesa/drm@0d889201d1.
