[Spice-devel] [RFC PATCH spice v3 1/3] QXL interface: add a function to identify monitors in the guest

[Gerd Hoffmann]

  Hi,

> + * The device_display_id_{start,count} denotes the sequence of device display
> + * IDs that map to the zero-based sequence of monitor IDs provided by monitors
> + * config on this interface. For example with device_display_id_start = 2 and
> + * device_display_id_count = 3 you get the following mapping:

> + *          0  ->  2
> + *          1  ->  3
> + *          2  ->  4

> + * Note this example is unsupported in practice. The only supported cases are
> + * either a single device display ID (count = 1) or multiple device display IDs
> + * in a sequence starting from 0.

This is confusing.  The usage of this api in the qemu counterpart looks
sane though.

cheers,
