Thanks to72d277a7,1ed2cb32, and others, EDID (Extended Display Identification Data) is propagated by QEMU such that a virtual display presents legitimate metadata (e.g., name, serial number, preferred resolutions, etc.) to its connected guest. This change adds the ability to specify the EDID name for a particular virtio-vga display. Previously, every virtual display would have the same name: "QEMU Monitor". Now, we can inject names of displays in order to test guest behavior that is specific to display names. We provide the ability to inject the display name from the frontend since this is guest visible data. Furthermore, this makes it clear where N potential display outputs would get their name from (which will be added in a future change). Note that we have elected to use a struct here for output data for extensibility - we intend to add per-output fields like resolution in a future change. It should be noted that EDID names longer than 12 bytes will be truncated per spec (I think?). Testing: verified that when I specified 2 outputs for a virtio-gpu with edid_name set, the names matched those that I configured with my vnc display. -display vnc=localhost:0,id=aaa,display=vga,head=0 \ -display vnc=localhost:1,id=bbb,display=vga,head=1 \ -device '{"driver":"virtio-vga", "max_outputs":2, "id":"vga", "outputs":[ { "name":"AAA" }, { "name":"BBB" } ]}' Signed-off-by: Andrew Keesler <ankeesler@google.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20250709121126.2946088-2-ankeesler@google.com>
