be812c0ab7 spice: set device address and device display ID in QXL interface
Calls the new SPICE QXL interface function spice_qxl_set_device_info to
set the hardware address of the graphics device represented by the QXL
interface (e.g. a PCI path) and the device display IDs (the IDs of the
device's monitors that belong to this QXL interface).

Also stops using the deprecated spice_qxl_set_max_monitors, the new
interface function replaces it.

9c956e6461 spice: prepare for upcoming spice-server change
Future spice-server versions will call the client_monitors_config
callback with the monitors list filtered to only include the monitors
of the given display channel (aka QXLInstance).  Luckily this is easily
detectable at runtime, so we can prepare for that in advance and also
make qemu compatible with both old and new spice-server versions.

While being at it also use the console index instead of head number as
array index.  The later doesn't work correctly in case multiple display
devices are present.

242d01336d dmabuf: add y0_top, pass it to spice
Some scanouts during boot are top-down without it.

y0_top is set from VHOST_USER_GPU_DMABUF_SCANOUT code path in the last
patch of this series.

In current QEMU code base, only vfio/display uses dmabuf API. But the
VFIO query interface doesn't provide or need that detail so far.

006bf4641b spice-display: fix qemu_spice_cursor_refresh_bh locking
spice-display should not call the ui/console.c functions dpy_cursor_define
and dpy_moues_set with the SimpleSpiceDisplay lock taken.  That will cause
a deadlock, because the DisplayChangeListener callbacks will take the lock
again.  It is also in general a bad idea to invoke generic callbacks with a
lock taken, because it can cause AB-BA deadlocks in the long run.  The only
thing that requires care is that the cursor may disappear as soon as the
mutex is released, so you need an extra cursor_get/cursor_put pair.

b153f9019b spice: add cursor_dmabuf support
Add support for cursor dmabufs.  qemu has to render the cursor for
that, so in case a cursor is present qemu allocates a new dmabuf, blits
the scanout, blends in the pointer and passes on the new dmabuf to
spice-server.  Without cursor qemu continues to simply pass on the
scanout dmabuf as-is.

4423184376 spice/gl: render DisplaySurface via opengl
This switches over spice (in opengl mode) to render DisplaySurface
updates into a opengl texture, using the helper functions in
ui/console-gl.c.  With this patch applied spice (with gl=on) will
stop using qxl rendering ops, it will use dma-buf passing all the
time, i.e. for bios/bootloader (before virtio-gpu driver is loaded)
too.

This should improve performance even using spice (with gl=on) with
non-accelerated stdvga because we stop squeezing all display updates
through a unix/tcp socket and basically using a shared memory transport
instead.

474114b730 spice: add opengl/virgl/dmabuf support
This adds support for dma-buf passing to spice.  This makes virtio-gpu
with 3d acceleration work with spice.

Workflow:
 * virglrenderer renders the guest command stream into a texture.
 * qemu exports the texture as dma-buf and passes on that dma-buf
   to spice-server.
 * spice-server passes the dma-buf to spice-client, using unix
   socket file descriptor passing.
 * spice-client asks the window systems composer to render the
   dma-buf to the screen.

Requires cutting edge spice (server) and spice-gtk (client) builds,
from git master branch.

Also requires libvirt managing your qemu instance, and using
"virt-viewer --attach $guest".  libvirt will connect spice-server and
spice-client using unix sockets instead of tcp sockets then, which
is required for file descriptor passing.

Works for the local case (spice server and client on the same machine)
only.  Supporting remote too is planned (by feeding the dma-bufs into
gpu-assisted video encoder), but not there yet.

gl mode is turned off by default, use "-spice gl=on,$otherargs" to
enable it.

555e72f2d0 spice: rework mirror allocation, add no-resize fast path
Add fast path to qemu_spice_display_switch in case old and new
displaysurface have identical size (happens with display panning
and page flipping).  We just swap the backing store then and don't
go through the whole process of deleting and creating the primary
surface.

To simplify the code a bit move mirror surface allocation to
qemu_spice_display_switch().

0b2824e5e4 spice: use bottom half instead of refresh timer for cursor updates
Calling directly doesn't work due to the qxl-render code running in
spice server thread context.  Meanwhile bottom half scheduling is
thread-safe though, so we can use that to kick a cursor update in
main i/o thread context.

ab9509ccea spice: make sure we don't overflow ssd->buf
Related spice-only bug.  We have a fixed 16 MB buffer here, being
presented to the spice-server as qxl video memory in case spice is
used with a non-qxl card.  It's also used with qxl in vga mode.

When using display resolutions requiring more than 16 MB of memory we
are going to overflow that buffer.  In theory the guest can write,
indirectly via spice-server.  The spice-server clears the memory after
setting a new video mode though, triggering a segfault in the overflow
case, so qemu crashes before the guest has a chance to do something
evil.

Fix that by switching to dynamic allocation for the buffer.

CVE-2014-3615

5643fc012c spice: add mouse cursor support
So you'll have a mouse pointer when running non-qxl gfx cards with
mouse pointer support (virtio-gpu, IIRC vmware too).
