Add a the new qemu_create_displaysurface_pixman function, to create
a DisplaySurface backed by an existing pixman image. In that case
there is no need to create a new pixman image pointing to the same
backing storage. We can just use the existing image directly.
This does not only simplify things a bit, but most importantly it
gets the reference counting right, so the backing storage for the
pixman image wouldn't be released underneath us.
Use new function in virtio-gpu, where using it actually fixes
use-after-free crashes.

Currently, virgl support has to go through a local unix socket, trying

This commit errors out when the user tries to start a VM with both GL

This would fit better in spice-server, but currently QEMU does not call

do this check in QEMU instead.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

[Fix compilation without the spice devel packages. - Paolo]
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type(). But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:
| struct q_obj_ImageInfoSpecificQCow2_wrapper {
| ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
| ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
| ImageInfoSpecificKind type;
| union { /* union tag is @type */
| void *data;
|- ImageInfoSpecificQCow2 *qcow2;
|- ImageInfoSpecificVmdk *vmdk;
|+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
| } u;
| };
Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation). Using the implicit type
also lets us get rid of the simple_union_type() hack.
Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access. The generated
qapi-visit.c code is also affected by the layout change:
|@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member
| }
| switch (obj->type) {
| case IMAGE_INFO_SPECIFIC_KIND_QCOW2:

This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest. Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.
Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle. Also there is no support for
absolute coordinates (tablet/touchscreen). So we are talking here about
basic mouse and keyboard support.
The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have). And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.
Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.
Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command
line. Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

An upcoming patch will alter how simple unions, like InputEvent, are
laid out, which will impact all lines of the form 'evt->u.XXX'
(expanding it to the longer 'evt->u.XXX.data'). For better
legibility in that patch, and less need for line wrapping, it's better
to use a temporary variable to reduce the effect of a layout change to
just the variable initializations, rather than every reference within
an InputEvent.
There was one instance in hid.c:hid_pointer_event() where the code
was referring to evt->u.rel inside the case label where evt->u.abs
is the correct name; thankfully, both members of the union have the
same type, so it happened to work, but it is now cleaner.

Spice hooks the migration status changes to figure out when to
transmit information to the new spice server; but the migration
status in postcopy doesn't quite fit - the destination starts
running before the end of the source migration.
It's not a case of hanging off the migration status change to
postcopy-active either, since that happens before we stop the
guest CPU.
Fix it by sending a notify just after sending the device state,
and adding a flag that can be tested by the notify receiver.

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.

vnc: distiguish between ipv4/ipv6 omitted vs set to off
sockets: remove use of QemuOpts from socket_dgram
sockets: remove use of QemuOpts from socket_connect
sockets: remove use of QemuOpts from socket_listen

The VNC code for interpreting QemuOpts does not currently
distinguish between ipv4/ipv6 being omitted, and being
set to 'off', because historically the 'ipv4' and 'ipv6'
options were just flags which did not accept a value.
The upshot is that if someone runs
$QEMU -vnc localhost:1,ipv6=off
QEMU still uses PF_UNSPEC and thus may still bind to IPv6,
when it should use PF_INET.
This is another instance of the problem previously fixed
for chardevs in
