Subject: [Qemu-devel] [PULL 2/6] console: block rendering until client is done
Date: Wed,  3 Feb 2016 12:16:44 +0100	[thread overview]
Message-ID: <1454498208-15164-3-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1454498208-15164-1-git-send-email-kraxel@redhat.com>

Allow gl user interfaces to block display device gl rendering.
The ui code might want to do that in case it takes a little
longer to bring things to screen, for example because we'll
hand over a dma-buf to another process (spice will do that).
