Up to now we have relied on the device type to identify a device tree
node creation function. Since we would like the vfio-platform device to
be instantiable with different compatible strings we introduce the
capability to specialize the node creation depending on actual
compatible value.
NodeCreationPair is renamed into BindingEntry. The struct is enhanced
with compat and match_fn() fields. We introduce a new matching function
adapted to the vfio-platform generic device.
Soon, the AMD XGBE can be instantiated with either manner, i.e.:
-device vfio-amd-xgbe,host=e0900000.xgmac
or using the new option line:
-device vfio-platform,host=e0900000.xgmac

Up to now the vfio-platform device has been abstract and could not be
instantiated. The integration of a new vfio platform device required
creating a dummy derived device which only set the compatible string.
Following the few vfio-platform device integrations we have seen the
actual requested adaptation happens on device tree node creation
(sysbus-fdt).
Hence remove the abstract setting, and read the list of compatible
values from sysfs if not set by a derived device.
Update the amd-xgbe and calxeda-xgmac drivers to fill in the number of
compatible values, as there can now be more than one.
Note that sysbus-fdt does not support the instantiation of the
vfio-platform device yet.

So we have a boot display when using a vgpu as primary display.
ramfb depends on a fw_cfg file. fw_cfg files can not be added and
removed at runtime, therefore a ramfb-enabled vfio device can't be
hotplugged.
Add a nohotplug variant of the vfio-pci device (as child class). Add
the ramfb property to the nohotplug variant only. So to enable the vgpu
display with boot support use this:
-device vfio-pci-nohotplug,display=on,ramfb=on,sysfsdev=...

In downstream distros like RHEL we'd like to disable some of the "legacy"
devices of QEMU. The ISA version of the Cirrus VGA device is one of these
legacy devices. So let's make the build process a little bit more flexible
here by putting the Cirrus ISA code into a separate file which is only
included if both, CONFIG_VGA_CIRRUS and CONFIG_VGA_ISA are set.
Note that this disables "isa-cirrus-vga" for the ppc-softmmu and the
alpha-softmmu target since CONFIG_VGA_ISA is not set there. But I think
this is OK since these targets are only interested in the PCI variant
anyway.

Per supported platforms doc[1], the various min GTK3 on relevant distros is:
RHEL-7.0: 3.8.8
RHEL-7.2: 3.14.13
RHEL-7.4: 3.22.10
RHEL-7.5: 3.22.26
Debian (Stretch): 3.22.11
Debian (Jessie): 3.14.5
OpenBSD (Ports): 3.22.30
FreeBSD (Ports): 3.22.29
OpenSUSE Leap 15: 3.22.30
SLE12-SP2: Unknown
Ubuntu (Xenial): 3.18.9
macOS (Homebrew): 3.22.30
This suggests that a minimum GTK3 of 3.14.0 is a reasonable target,
as users are unlikely to be stuck on RHEL-7.0/7.1 still

ui: deprecate use of GTK 2.x in favour of 3.x series
The GTK 3.0 release was made in Feb, 2011:
https://blog.gtk.org/2011/02/10/gtk-3-0-released/
That will soon be 7 years ago, which is enough time to consider
the 3.x series widely supported.
Thus we deprecate the GTK 2.x support, which will allow us to
delete it in the last release of 2018. By this time, GTK 3.x
will be almost 8 years old.

There are some 2D resource formats that can be used through virtio-gpu,
but which are not supported by SDL2 when used for a scanout; these are
all alpha-channel formats and also XBGR (RGBX in non-BE pixman).
Add these formats in the switch converting pixman to SDL format
constants so a guest cannot crash the VM by triggering the
g_assert_not_reached() with an unsupported format.

Introduces a VFIO based AP device. The device is defined via
the QEMU command line by specifying:
-device vfio-ap,sysfsdev=<path-to-mediated-matrix-device>
There may be only one vfio-ap device configured for a guest.
The mediated matrix device is created by the VFIO AP device
driver by writing a UUID to a sysfs attribute file (see
docs/vfio-ap.txt). The mediated matrix device will be named
after the UUID. Symbolic links to the $uuid are created in
many places, so the path to the mediated matrix device $uuid
can be specified in any of the following ways:
/sys/devices/vfio_ap/matrix/$uuid
/sys/devices/vfio_ap/matrix/mdev_supported_types/vfio_ap-passthrough/devices/$uuid
/sys/bus/mdev/devices/$uuid
/sys/bus/mdev/drivers/vfio_mdev/$uuid
When the vfio-ap device is realized, it acquires and opens the
VFIO iommu group to which the mediated matrix device is
bound. This causes a VFIO group notification event to be
signaled. The vfio_ap device driver's group notification
handler will get called at which time the device driver
will configure the the AP devices to which the guest will
be granted access.

Let's use the KVM_SET_DEVICE_ATTR ioctl to enable hardware
interpretation of AP instructions executed on the guest.
If the S390_FEAT_AP feature is switched on for the guest,
AP instructions must be interpreted by default; otherwise,
they will be intercepted.
This attribute setting may be overridden by a device. For example,
a device may want to provide AP instructions to the guest (i.e.,
S390_FEAT_AP turned on), but it may want to emulate them. In this
case, the AP instructions executed on the guest must be
intercepted; so when the device is realized, it must disable
interpretation.

A new CPU model feature and two new CPU model facilities are
introduced to support AP devices for a KVM guest.
CPU model features:
1. The S390_FEAT_AP CPU model feature indicates whether AP
instructions are available to the guest. This feature will
be enabled only if the AP instructions are available on the
linux host as determined by the availability of the
KVM_S390_VM_CRYPTO_ENABLE_APIE VM attribute which is exposed
by KVM only if the AP instructions are available on the
host.
This feature must be turned on from userspace to execute AP
instructions on the KVM guest. The QEMU command line to turn
this feature on looks something like this:
qemu-system-s390x ... -cpu xxx,ap=on ...
This feature will be supported for zEC12 and newer CPU models.
The feature will not be supported for older models because
there are few older systems on which to test and the older
crypto cards will be going out of service in the relatively
near future.
CPU model facilities:
1. The S390_FEAT_AP_QUERY_CONFIG_INFO feature indicates whether the
AP Query Configuration Information (QCI) facility is available
to the guest as determined by whether the facility is available
on the host. This feature will be exposed by KVM only if the
QCI facility is installed on the host.
2. The S390_FEAT_AP_FACILITY_TEST feature indicates whether the AP
Facility Test (APFT) facility is available to the guest as
determined by whether the facility is available on the host.
This feature will be exposed by KVM only if APFT is installed
on the host.

Several changes:
- We only allow generate header "inside" the tree. Why? Because we
need to connit the result, so it makes no sense to generate them on
the build dir.
- We only generate a single target each time. Getting all the
cross-compilers correctly is an impossible task. So know you do:
make -C tests/migration $target (native)
make CROSS_PREFIX=foo- -C tests/migratiion $target (cross)
And you are done.
- If we are building out of tree, we have no data about if we are
cross-compile or whatever. So instead of guess what is happening,
just do what I pointed on previous point.

According to PCI specification, subsystem id and subsystem vendor id
are present only in type 0 and type 2 headers (at different offsets),
but not in type 1 headers.
Thus we should make this data optional in struct PciDeviceId and skip
reporting them via HMP if the information is not available.
Additional (wrong information) about PCI bridges (Type1 devices) has been
added in 5383a705 and fortunately not released. This patch fixes that
problem. The problem was spotted by Markus.

According to documentation, NEED_REPLY_MASK should not be set
for VHOST_USER_SET_MEM_TABLE request in postcopy mode.
This restriction was mistakenly applied to 'reply_supported'

modifies the memory, as required for the migration test.

This patch adds migration test support for aarch64. The test code, which
implements the same functionality as x86, is booted as a kernel in qemu.
Here are the design choices we make for aarch64:
* We choose this -kernel approach because aarch64 QEMU doesn't provide a
built-in fw like x86 does. So instead of relying on a boot loader, we
use -kernel approach for aarch64.
* The serial output is sent to PL011 directly.
* The physical memory base for mach-virt machine is 0x40000000. We change
the start_address and end_address for aarch64.
In addition to providing the binary, this patch also includes the source
code and the build script in tests/migration/aarch64. So users can change
the source and/or re-compile the binary as they wish.

Commit 2aece63c8a "hostmem: detect host backend memory is being used
properly" fixed "ivshmem-plain" to reject memory backends that are
already in use, and to block their deletion while in use. Two bugs
escaped review:
* New ivshmem_plain_exit() fails to call ivshmem_exit(). This breaks
unplug. Reproducer: migration after unplug still fails with
"Migration is disabled when using feature 'peer mode' in device
'ivshmem'".
* It failed to update legacy "ivshmem". Harmless, because it creates
the memory backend itself, and nothing else should use it.
Fix by moving the two host_memory_backend_set_mapped() calls into
ivshmem_common_realize() and ivshmem_exit(), guarded by s->hostmem.
