490a9d9b36 serial: start making SerialMM a sysbus device
Memory mapped serial device is in fact a sysbus device. The following
patches will make use of sysbus facilities for resource and
registration. In particular, "serial-mm: use sysbus facilities" will
move internal serial realization to serial_mm_realize callback to
follow qdev best practices.

4cc017e505 serial: register vmsd with DeviceClass
Migration from old to new code works, however the other way fails for
devices that use serial_init/serial_mm_init with "base", used as
instance_id previously.

(with qdev_set_legacy_instance_id, the alias_id is only used in
savevm.c:find_se(), and thus can only be used to match against
"legacy" instance id values. On new code, instance_id is generated
incrementally from 0 with calculate_new_instance_id(), based on
"qdev-path/vmsd-name")

7781b88ee4 serial: initial qom-ification
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).

e24e58e8ac q800: implement mac rom reset function for BIOS-less mode
On Linux, calling `reboot(RB_AUTOBOOT);` will result in
arch/m68k/mac/misc.c's mac_reset function being called. That in turn
looks at the rombase (or uses 0x40800000 is there's no rombase), adds
0xa, and jumps to that address. At the moment, there's nothing there, so
the kernel just crashes when trying to reboot. So, this commit adds a
very simple implementation at that location, which just writes to via2
to power down. We also correct the value of ROMBASE while we're at it.

7aca3782d9 hw/display/sm501: Always map the UART0
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 12051d82f, qemu_chr_fe_init() accepts a NULL chardev.
Let's remove the chardev check and always map the UART in the
chipset memory.

c4d1069c25 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".

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

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

The present bit check for pasid entry (pe) and pasid directory
entry (pdire) were missed in previous commits as fpd bit check
doesn't require present bit as "Set". This patch adds the present
bit check for callers which wants to get a valid pe/pdire.

1bf8a989a5 virtio: make seg_max virtqueue size dependent
Before the patch, seg_max parameter was immutable and hardcoded
to 126 (128 - 2) without respect to queue size. This has two negative effects:

1. when queue size is < 128, we have Virtio 1.1 specfication violation:
   (2.6.5.3.1 Driver Requirements) seq_max must be <= queue_size.
   This violation affects the old Linux guests (ver < 4.14). These guests
   crash on these queue_size setups.

2. when queue_size > 128, as was pointed out by Denis Lunev <den@virtuozzo.com>,
   seg_max restrics guest's block request length which affects guests'
   performance making them issues more block request than needed.
   https://lists.gnu.org/archive/html/qemu-devel/2017-12/msg03721.html

To mitigate this two effects, the patch adds the property adjusting seg_max
to queue size automaticaly. Since seg_max is a guest visible parameter,
the property is machine type managable and allows to choose between
old (seg_max = 126 always) and new (seg_max = queue_size - 2) behaviors.

Not to change the behavior of the older VMs, prevent setting the default
seg_max_adjust value for older machine types.

df016a1998 hda-codec: fix playback rate control
Since commit 1930616b98 "audio: make mixeng optional" the
function hda_audio_output_cb can no longer assume the function
parameter avail contains the free buffer size. With the playback
mixing-engine turned off this leads to a broken playback rate
control and playback buffer drops in regular intervals.

This patch moves down the rate calculation, so the correct
buffer fill level is used for the calculation.

the latests machine type by now is 5.0 and it should use its own

f047243938 vhost-user-scsi: reset the device if supported
If the vhost-user-scsi backend supports the VHOST_USER_F_RESET_DEVICE
protocol feature, then the device can be reset when requested.

If this feature is not supported, do not try a reset as this will send
a VHOST_USER_RESET_OWNER that the backend is not expecting,
potentially putting into an inoperable state.
