-------
Submitted with commit cc4de29cf24f06e51dbc7e221ccb89162be525d4 by Sebastian
Kügler to branch master.
Repository: libkscreen
Description
-------
This adds a kwayland backend to libkscreen.
This backend uses KWayland's OutputManagement protocol for enlisting and
configuring devices.
Enlisting outputs
KScreen's outputs are created from KWayland::Client::OutputDevice objects,
they copy the data into kscreen's Outputs, and update these objects. A list
of outputs is requested from the client Registry object.
Configuring outputs
The backend asks the global OutputManagement interface for an
OutputConfiguration
object, then sets the changes per outputdevice on this object, and asks the
compositor to apply() this configuration.
For this to work, the compositor should support the Wayland
org_kde_kwin_outputdevice
and org_kde_kwin_outputmanagement protocols, for example through
KWayland::Server classes OutputDevice, OutputManagmenent and OuputConfiguration.
General working
WaylandBackend creates a global static internal config, available through
WaylandBackend::internalConfig(). WaylandConfig binds to the wl_registry
callbacks and catches org_kde_kwin_outputdevice creation and destruction.
It passes org_kde_kwin_outputdevice creation and removal on to
WB::internalConfig() to handle its internal data representation as
WaylandOutput.
WaylandOutput binds to org_kde_kwin_outputdevice's callback, and gets notified
of geometry and modes, including changes. WaylandOutput administrates the
internal representation of these objects, and invokes the global notifier,
which then runs the pointers it holds through the updateK* methods in
Wayland{Screen,Output,...}.
KScreen:{Screen,Output,Edid,Mode} objects are created from the internal
representation as requested (usually triggered by the creation of a
KScreen::Config object through KScreen::Config::current()). As with other
backends, the objects which are handed out to the lib's user are expected
to be deleted by the user, the backend only takes ownership of its internal
data representation objects.

Testing
-------
The patch contains a test server, which is used for the autotests.
The test server uses KWayland's server classes and is set up from the json
config data we use for the other tests. That means that the backends runs
against a real server to test everything.
I also tested the kscreen UI, which also works as expected.
Thanks,
Sebastian Kügler
