The size of the BAR is 0x1000 (main registers) + 8 bytes for each
queue. Currently, the size of the BAR is calculated like so:
n->reg_size = pow2ceil(0x1004 + 2 * (n->num_queues + 1) * 4);
Since the 'num_queues' parameter already accounts for the admin queue,
this should in any case not need to be incremented by one. Also, the
size should be initialized to (0x1000).
n->reg_size = pow2ceil(0x1000 + 2 * n->num_queues * 4);
This, with the default value of num_queues (64), we will set aside room
for 1 admin queue and 63 I/O queues (4 bytes per doorbell, 2 doorbells
per queue).

On restart, we were scheduling a BH to process queued requests, which
would run before starting up the data plane, leading to those requests
being assigned and started on coroutines on the main context.
This could cause requests to be wrongly processed in parallel from
different threads (the main thread and the iothread managing the data
plane), potentially leading to multiple issues.
For example, stopping and resuming a VM multiple times while the guest
is generating I/O on a virtio_blk device can trigger a crash with a
stack tracing looking like this one:

Looks like the logic was copied over from q35.
q35 does this for backward compatibility, there is no reason to do this
on microvm though. Also microvm doesn't need much mmio space, 1G is
more than enough. Using an mmio window smaller than 1G is bad for
gigabyte alignment and hugepages though. So split @ 3G unconditionally.

Requires libusb 1.0.23 or newer. The hostdevice property is only

init_event_facility() creates the SCLP events bus with two SCLP event
devices (sclpquiesce and sclp-cpu-hotplug). It leaves the devices
unrealized. A comment explains they will be realized "via the bus".
The bus's realize method sclp_events_bus_realize() indeed realizes all
unrealized devices on this bus. It carries a TODO comment claiming
this "has to be done in common code". No other bus realize method
realizes its devices.
The common code in question is bus_set_realized(), which has a TODO
comment asking for recursive realization. It's been asking for years.
The only devices sclp_events_bus_realize() will ever realize are the
two init_event_facility() puts there.
Simplify as follows:
* Make the devices members of the event facility instance struct, just
like the bus. object_initialize_child() is simpler than
object_property_add_child() and object_unref().
* Realize them in the event facility realize method.
This is in line with how such things are done elsewhere.

This is the same transformation as in the previous commit, except
sysbus_init_child_obj() and realize are too separated for the commit's
Coccinelle script to handle, typically because sysbus_init_child_obj()
is in a device's instance_init() method, and the matching realize is
in its realize() method.
Perhaps a Coccinelle wizard could make it transform that pattern, but
I'm just a bungler, and the best I can do is transforming the two
separate parts separately:

This commit has only the pairs where object_initialize_child()'s
@child and sysbus_realize()'s @dev argument text match exactly within
the same source file.
Note that Coccinelle chokes on ARMSSE typedef vs. macro in
hw/arm/armsse.c. Worked around by temporarily renaming the macro for
the spatch run.

Sysbus devices almost always plug into the main system bus.
qdev_create() even has a convenience feature to make that easy: a null
bus argument gets replaced by the main system bus. qdev_realize() and
qdev_realize_and_unref() do the same.
We can do better. Provide convenience wrappers around qdev_realize()
and qdev_realize_and_unref() that don't take a @bus argument. They
always pass the main system bus.

ssi_auto_connect_slaves(parent, cs_line, bus) iterates over @parent's
QOM children @dev of type TYPE_SSI_SLAVE. It puts these on @bus, and
sets cs_line[] to qdev_get_gpio_in_named(dev, SSI_GPIO_CS, 0).
Suspicious: there is no protection against overrunning cs_line[].
Turns out it's safe because ssi_auto_connect_slaves() never finds any
such children. Its called by realize methods of some (but not all)
devices providing an SSI bus, and gets passed the device.
SSI slave devices are always created with ssi_create_slave_no_init(),
optionally via ssi_create_slave(). This adds them to their SSI bus.
It doesn't set their QOM parent.
ssi_create_slave_no_init() is always immediately followed by
qdev_init_nofail(), with no QOM parent assigned, so
device_set_realized() puts the device into the /machine/unattached/
orphanage. None become QOM children of a device providing an SSI bus.
ssi_auto_connect_slaves() was added in commit b4ae3cfa57 "ssi: Add
slave autoconnect helper". I can't see which slaves it was supposed
to connect back then.

In addition to the qdev_create() patterns converted so far, we have a
qdev_set_parent_bus() pattern. Mostly when we embed a device in a
parent device rather than allocating it on the heap.

We commonly plug devices into their bus right when we create them,
like this:
dev = qdev_create(bus, type_name);
Note that @dev is a weak reference. The reference from @bus to @dev
is the only strong one.
We realize at some later time, either with
object_property_set_bool(OBJECT(dev), true, "realized", errp);
or its convenience wrapper
qdev_init_nofail(dev);
If @dev still has no QOM parent then, realizing makes the
/machine/unattached/ orphanage its QOM parent.
Note that the device returned by qdev_create() is plugged into a bus,
but doesn't have a QOM parent, yet. Until it acquires one,
unrealizing the bus will hang in bus_unparent():
while ((kid = QTAILQ_FIRST(&bus->children)) != NULL) {
DeviceState *dev = kid->child;
object_unparent(OBJECT(dev));
}
object_unparent() does nothing when its argument has no QOM parent,
and the loop spins forever.
Device state "no QOM parent, but plugged into bus" is dangerous.
Paolo suggested to delay plugging into the bus until realize. We need
to plug into the parent bus before we call the device's realize
method, in case it uses the parent bus. So the dangerous state still
exists, but only within realization, where we can manage it safely.
This commit creates infrastructure to do this:
dev = qdev_new(type_name);
...
qdev_realize_and_unref(dev, bus, errp)
Note that @dev becomes a strong reference here.
qdev_realize_and_unref() drops it. There is also plain
qdev_realize(), which doesn't drop it.
The remainder of this series will convert all users to this new
interface.

Commit 260bc9d8aa "hw/sd/sd.c: QOMify" QOMified only the device
itself, not its users. It kept sd_init() around for non-QOMified
users.
More than four years later, three such users remain: omap1 (machines
cheetah, sx1, sx1-v1) and omap2 (machines n800, n810) are not
QOMified, and pl181 (machines integratorcp, realview-eb,
realview-eb-mpcore, realview-pb-a8 realview-pbx-a9, versatileab,
versatilepb, vexpress-a15, vexpress-a9) is not QOMified properly.
The issue I presently have with this: an "sd-card" device should plug
into an "sd-bus" (its DeviceClass member bus_type says so), but
sd_init() leaves it unplugged. This is normally a bug (I just fixed
some instances), and I'd like to assert proper pluggedness to prevent
regressions. However, the qdev-but-not-quite thing returned by
sd_init() would fail the assertion. Meh.
Make sd_init() hide it from QOM/qdev. Visible in "info qom-tree",
here's the change for cheetah:
/machine (cheetah-machine)
[...]
/unattached (container)
[...]
/device[5] (serial-mm)
/serial (serial)

The number of MACs supported by an Aspeed SoC is defined by "macs_num"
under the SoC model, that is two for the AST2400 and AST2500 and four
for the AST2600. The model initializes the maximum number of supported
MACs but the number of realized devices is capped by the number of
network device back-ends defined on the command line. This can leave
unrealized devices hanging around in the QOM composition tree.
To get virtual hardware that matches the physical hardware, you have
to pass exactly as many -nic options as there are MACs, and some of
them must be -nic none:
* Machines ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc,
swift-bmc, and witherspoon-bmc: two -nic, and the second one must be
-nic none.
* Machine ast2600-evb: four -nic, the first one must be -nic none.
* Machine tacoma-bmc: four nic, the first two and the last one must be
-nic none.
Modify the machine initialization to define which MACs are attached to
a network device back-end using a bit-field property "macs-mask" and
let the SoC realize all network devices.
The default setting of "macs-mask" is "use MAC0" only, which works for
all our AST2400 and AST2500 machines. The AST2600 machines have
different configurations. The AST2600 EVB machine activates MAC1, MAC2
and MAC3 and the Tacoma BMC machine activates MAC2.
Incompatible CLI change: -nic options now apply to *active* MACs:
MAC1, MAC2, MAC3 for ast2600-evb, MAC2 for tacoma-bmc, and MAC0 for
all the others.

Commit ece09beec4 ("aspeed: introduce a configurable number of CPU
per machine") was a convient change during bringup but the Aspeed SoCs
have a fixed number of CPUs : one for the AST2400 and AST2500, and two
for the AST2600.
When the number of CPUs configured with -smp is less than the SoC's
fixed number, the "unconfigured" CPUs are left unrealized. This can
happen for machines ast2600-evb and tacoma-bmc, where the SoC's fixed
number is 2. To get virtual hardware that matches the physical
hardware, you have to pass -smp cpus=2 (or its sugared form -smp 2).
We normally reject -smp cpus=N when N exceeds the machine's limit.
Except we ignore cpus=2 (and only cpus=2) with a warning for machines
ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc, swift-bmc, and
witherspoon-bmc.
Remove the "num-cpu" property from the SoC state and use the fixed
number of CPUs defined in the SoC class instead. Compute the default,
min, max number of CPUs of the machine directly from the SoC class
definition.

terrier, tosa, verdex, and z2.
In theory, a device becomes real only on realize. In practice, the
transition from unreal to real is a fuzzy one. The work to make a
device real can be spread between realize methods (fine),
instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize). Depending on
what exactly is done where, a device can work even when we neglect
to realize it.
This one appears to work. Nevertheless, it's a clear misuse of the
interface. Even when it works today (more or less by chance), it can
break tomorrow.
Fix by realizing it right away. Visible in "info qom-tree"; here's
the change for akita:
/machine (akita-machine)

/unattached (container)

+ /pxa2xx-mmci[0] (qemu:memory-region)

stm32f405_soc_initfn() creates six such devices, but
stm32f405_soc_realize() realizes only one. Affects machine
netduinoplus2.
In theory, a device becomes real only on realize. In practice, the
transition from unreal to real is a fuzzy one. The work to make a

instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize). Depending on
what exactly is done where, a device can work even when we neglect

The five unrealized devices appear to stay unreal: neither MMIO nor
IRQ get wired up.

The CPUReadMemoryFunc/CPUWriteMemoryFunc typedefs are legacy
remnant from before the conversion to MemoryRegions.
Since they are now only used in tusb6010.c and hcd-musb.c,
move them to "hw/usb/musb.h" and rename them appropriately.
