Hello, this series introduces a new mechanism to identify monitors across the host and guest boundary, using the pair (device_address and device_display_id). device_address is a HW address of a graphics device (a PCI address to be specific, though other address domains can be used as well), device_display_id is an ID of the monitor on that device. This information is gathered from QEMU (regular spice) or spice-streaming-agent (for the streaming channels) and a mapping of (channel_id, monitor_id) -> (device_address, device_display_id) is sent from spice server to the vd_agent. vd_agent uses this mapping to translate the former ID in incoming messages to the latter. This series follows up on the "QXL interface to set monitor ID" series [1] and then Jonathon Jongsma's "Use the PCI addr and display ID" [2] follows up on this to make a complete solution. You can also find the code in the following branches: https://gitlab.freedesktop.org/lukash/spice-protocol/commits/monitor-id-v3-2 https://gitlab.freedesktop.org/lukash/spice/commits/monitor-id-v3-2 https://gitlab.freedesktop.org/lukash/spice-streaming-agent/commits/monitor-id-v3-2 https://gitlab.freedesktop.org/lukash/vd_agent/commits/monitor-id-v3-2 Cheers, Lukas Changes since v2: * Fixed wrong commits for spice streaming agent. * Changed g_error to g_warning. * Fixed buffer overflows when reading device_address from the virtio port on the server. * Removed an unnecessary header include in the server. * Fixed a buffer overflow when reading device_address in the vd_agent.
