Subject: [Qemu-devel] [PATCH 0/4] spice: improve vga mode performance
Date: Wed, 5 Sep 2012 11:41:57 +0200 [thread overview]
Message-ID: <1346838121-10164-1-git-send-email-kraxel@redhat.com> (raw)
Hi,
This patch series makes spice be more clever on screen updates when in
vga mode (i.e. without qxl guest driver loaded or when using a non-qxl
vga card). qemu keeps a copy of the screen with the content forwarded
to spice-server, then on updates it goes compare the guest screen with
the copy to figure what has really changed.
cheers,
Gerd
