Subject: [PATCH 16/25] spice/qxl: move worker wrappers
Move the wrapper functions which are used by qxl only to qxl.c.
Rename them from qemu_spice_* to qxl_spice_*. Also pass in a
qxl state pointer instead of a SimpleSpiceDisplay pointer.

Subject: [PATCH 17/25] qxl: fix surface tracking & locking
Surface tracking needs proper locking since it is used from vcpu and spice
worker threads, add it. Also reset the surface counter when zapping all
surfaces.

Subject: [PATCH 19/25] qxl: error handling fixes and cleanups.
Add qxl_guest_bug() function which is supposed to be called in case
sanity checks of guest requests fail. It raises an error IRQ and
logs a message in case guest debugging is enabled.
Make PANIC_ON() abort instead of exit. That macro should be used
for qemu bugs only, any guest-triggerable stuff should use the new
qxl_guest_bug() function instead.
Convert a few easy cases from PANIC_ON() to qxl_guest_bug() to
show intended usage.

Subject: [PATCH 22/25] qxl: async io support using new spice api
Some of the QXL port i/o commands are waiting for the spice server to
complete certain actions. Add async versions for these commands, so we
don't block the vcpu while the spice server processses the command.
Instead the qxl device will raise an IRQ when done.
The async command processing relies on an added QXLInterface::async_complete
and added QXLWorker::*_async additions, in spice server qxl >= 3.1

>From b751be42f3da5666bd11d5a0acb20f225d9a4eb9 Mon Sep 17 00:00:00 2001
From: Alon Levy <alevy@redhat.com>
Date: Sun, 5 Jun 2011 11:01:48 +0300
Subject: [PATCH 23/25] qxl: add QXL_IO_FLUSH_{SURFACES,RELEASE} for guest
S3&S4 support
Add two new IOs.
QXL_IO_FLUSH_SURFACES - equivalent to update area for all surfaces, used
to reduce vmexits from NumSurfaces to 1 on guest S3, S4 and resolution change (windows
driver implementation is such that this is done on each of those occasions).
QXL_IO_FLUSH_RELEASE - used to ensure anything on last_release is put on the release ring
for the client to free.

>From a1f7b1a638423f74a7a8e3e141f760777dcbd1ab Mon Sep 17 00:00:00 2001
From: Alon Levy <alevy@redhat.com>
Date: Thu, 28 Jul 2011 15:08:48 +0300
Subject: [PATCH 25/25] virtio-serial-bus: replay guest_open on migration
When migrating a host with with a spice agent running the mouse becomes
non operational after the migration. This is rhbz #725965.
The problem is that after migration spice doesn't know the guest agent is open.
Spice is just a char dev here. And a chardev cannot query it's device, the
device has to let the chardev know when it is open. Right now after migration
the chardev which is recreated is in it's default state, which assumes the
guest is disconnected.
Char devices carry no information across migration, but the virtio-serial does
already carry the guest_connected state. This patch passes that bit to the
chardev.
