[Qemu-devel] [PATCH 2/8] console: add state notifiers for ui<->display |
Date: |
Wed, 20 Nov 2013 15:52:35 +1000 |
From: Dave Airlie <address@hidden>
These are to be used for the UI to signal the video display,
and vice-versa about changes in the state of a console, like
size and offsets in relation to other consoles for input handling.
