From: Marc-André Lureau <marcandre.lur...@redhat.com> Hi,
The D-Bus display doesn't work on Windows, since it relies on FDs transfer over Unix domain socket. This isn't (yet) supported on Windows. To make it work, the interfaces are adapted to use 'ay' WSASocketW data instead of 'h' (in a similar fashion as QMP 'get-win32-socket'). A simple XML preprocessor helps generating the target-specific OS interfaces. The performance on Windows isn't great though, since there is no DMABUF scanout sharing between QEMU and the client for example. The first improvement introduces a org.qemu.Display1.Listener.Win32.Map interface for shared display/console memory. This can work regardless of 3d accelerated or not, and should work across various GL implementations as well. The second improvement relies on ANGLE/EGL Direct3D extensions enabled in virgl (pending review at https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/1103) to create shareable Texture2Ds and share them when the client implements the org.qemu.Display1.Listener.Win32.D3D11 interface. This should give comparable performance as in-process display hopefully.
