Well, one idea is using dbus (discovery/setup) and pipewire (data
streams) to allow other applications access the guest display (also
audio, input, ...). Simliar to gnome exporting the wayland display
that way for remote access and screen sharing.
pipewire supports using dmabufs, so that should allow to decouple user
interface code from qemu without making compromises on performance,
which is probably quite useful for a number of use cases, like a
zero-copy wayland client, or a client using drm directly.
Right now pipewire support is at "idea" level, there isn't even a
proof-of-concept for that. So it surely doesn't help short-term, but
IMHO this makes alot of sense medium/long-term.
Marc-André has experimental code for a dbus-based UI for qemu. It
doesn't use pipewire as data transport though. At least the first
version posted a while ago @ qemu-devel doesn't.
take care,
Gerd
