GraphicHw.gl_flushed was introduced to notify the
device (vhost-user-gpu) that the GL resources (the display scanout) are
no longer needed.
It was decoupled from QEMU own gl-blocking mechanism, but that
difference isn't helping. Instead, we can reuse QEMU gl-blocking and
notify virtio_gpu_gl_flushed() when unblocking (to unlock
vhost-user-gpu).
An extra block/unblock is added arount dpy_gl_update() so existing
backends that don't block will have the flush event handled. It will
also help when there are no backends associated.

From: Marc-André Lureau <marcandre.lureau@redhat.com>
For now, only one listener can receive GL events. Let's dispatch to all
listeners. (preliminary check ensure there is a single listener now
during regitration, and in next patches, compatible listeners only)

From: Marc-André Lureau <marcandre.lureau@redhat.com>
Add a new DisplayScanout structure to save the current scanout details.
This allows to attach later UI backends and set the scanout.
Introduce displaychangelistener_display_console() helper function to
handle the dpy_gfx_switch/gl_scanout() & dpy_gfx_update() calls.

Add a new dbus-doc directive to import D-Bus interfaces documentation
from the introspection XML. The comments annotations follow the
gtkdoc/kerneldoc style, and should be formatted with reST.
Note: I realize after the fact that I was implementing those modules
with sphinx 4, and that we have much lower requirements. Instead of
lowering the features and code (removing type annotations etc), let's
have a warning in the documentation when the D-Bus modules can't be
used, and point to the source XML file in that case.

From: Marc-André Lureau <marcandre.lureau@redhat.com>
The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.
By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.
The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.
The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:
$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0
org.qemu.Display1.Console interface - - -

.SetUIInfo method qqiiuu - -

.Head property u 0 emits-change
.Height property u 480 emits-change
.Label property s "VGA" emits-change
.Type property s "Graphic" emits-change
.Width property u 640 emits-change

See the interfaces XML source file and Sphinx docs for the generated API
documentations.

To: qemu-devel
Cc: peter.maydell, richard.henderson, kraxel, Marc-André Lureau
From: Marc-André Lureau <marcandre.lureau@redhat.com>
Add an option to use direct connections instead of via the bus. Clients
are accepted with QMP add_client.
This allows to provide the D-Bus display without a bus. It also
simplifies the testing setup (some CI have issues to setup a D-Bus bus
in a container).

From: marcandre.lureau @ 2021-12-17 14:37 UTC (permalink / raw)
To: qemu-devel
Cc: peter.maydell, richard.henderson, kraxel, Marc-André Lureau
From: Marc-André Lureau <marcandre.lureau@redhat.com>
Add a new -audio backend that accepts D-Bus clients/listeners to handle
playback & recording, to be exported via the -display dbus.
Example usage:
-audiodev dbus,in.mixing-engine=off,out.mixing-engine=off,id=dbus
-display dbus,audiodev=dbus
