Investigating GUI agent performance would require knowing how Windows windowing and input APIs work as well as how to operate a system profiler. You can find the agent's code here: https://github.com/QubesOS/qubes-gui-agent-windows/tree/master It has two main components: a custom video driver and a background service. The driver manages display memory and provides the service with address of the framebuffer (and notifies when a refresh occurs). The service either maintains a list of application windows (in seamless mode) or just a desktop window and sends this info to dom0. Service also receives input events from dom0 and "replies" them in the Windows VM. I think the last part (input simulation) is the main case of poor performance, but you would need to double check this. As for audio support, I think implementing a pulseaudio endpoint on Windows and connecting it to dom0 would be your best bet. I don't know the details on how the audio works for Linux VMs, but feel free to ask on this mailing list if you want to know more. See this for Linux implementation: https://github.com/QubesOS/qubes-gui-agent-linux/tree/master/pulse I'm not sure how well pulseaudio runs on Windows so that would be the first thing to check. I hope that helps! -- Best Regards, Rafał Wojdyła Invisible Things Lab -- You received this message because you are subscribed to the Google Groups "qubes-devel" group.
