[Qemu-devel] [PATCH 3/8] console: add information retrival wrappers

[Dave Airlie]

From: Dave Airlie <address@hidden>

We need to know how many graphics consoles are registered in the UI
code so it knows how many windows it should prepare for etc, also
so that it could potentially warn for cases it can't handle.

We also need to know the console index so we can add it to the list.
(maybe we don't).
