      serial: initial qom-ification · 7781b88e
      由 Marc-André Lureau 提交于 
      Make SerialState a device (the following patches will introduce IO/MM
sysbus serial devices)

None of the serial_{,mm}_init() callers actually free the returned
value (even if they did, it would be quite harmless), so we can change
the object allocation at will.

However, the devices that embed SerialState must now have their field
QOM-initialized manually (isa, pci, pci-multi).

      chardev: generate an internal id when none given · 1e419ee6
      由 Marc-André Lureau 提交于 
      Internally, qemu may create chardev without ID. Those will not be
looked up with qemu_chr_find(), which prevents using qdev_prop_set_chr().

Use id_generate(), to generate an internal name (prefixed with #), so
no conflict exist with user-named chardev.

      hw/display/sm501: Always map the UART0 · 7aca3782
      由 Philippe Mathieu-Daudé 提交于 
      The SM501 is a Mobile Multimedia Companion Chip with 2 UARTs.
This model only implements the first UART. Being part of the
chipset, the UART block is always mapped in memory, regardless
of whether we provide a chardev backend.

Since commit 12051d82, qemu_chr_fe_init() accepts a NULL chardev.
Let's remove the chardev check and always map the UART in the
chipset memory.

      由 Peter Maydell 提交于 
      Add dbus-vmstate

Hi,

With external processes or helpers participating to the VM support, it
becomes necessary to handle their migration. Various options exist to
transfer their state:
1) as the VM memory, RAM or devices (we could say that's how
   vhost-user devices can be handled today, they are expected to
   restore from ring state)
2) other "vmstate" (as with TPM emulator state blobs)
3) left to be handled by management layer

1) is not practical, since an external processes may legitimatelly
need arbitrary state date to back a device or a service, or may not
even have an associated device.

2) needs ad-hoc code for each helper, but is simple and working

3) is complicated for management layer, QEMU has the migration timing

The proposed "dbus-vmstate" object will connect to a given D-Bus
address, and save/load from org.qemu.VMState1 owners on migration.

Thus helpers can easily have their state migrated with QEMU, without
implementing ad-hoc support (such as done for TPM emulation)

D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to
work on various other OSes. There are several implementations and good
bindings for various languages.  (the tests/dbus-vmstate-test.c is a
good example of how simple the implementation of services can be, even
in C)

dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use
a slirp helper process".

v2:
 - fix build with broken mingw-glib
