[Spice-devel] [PATCH 0/8] Monitor ID between host and guest

[Lukáš Hrázký]

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.

Cheers,
Lukas
