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.

pxa2xx_mmci_init() creates a "pxa2xx-mmci" device, but neglects to
realize it. Affects machines akita, borzoi, connex, mainstone, spitz,
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:

When QEMU is used without any graphical window,
QEMU execution is terminated with the signal (e.g., Ctrl-C).
Signal processing in QEMU does not include
qemu_system_shutdown_request call. That is why shutdown
event is not recorded by record/replay in this case.
This patch adds shutdown event to the end of the record log.
Now every replay will shutdown the machine at the end.

SEVState is contained with SevGuestState. We've now fixed redundancies
and name conflicts, so there's no real point to the nested structure. Just
move all the fields of SEVState into SevGuestState.
This eliminates the SEVState structure, which as a bonus removes the
confusion with the SevState enum.

The user can explicitly specify a handle via the "handle" property wired
to SevGuestState::handle. That gets passed to the KVM_SEV_LAUNCH_START
ioctl() which may update it, the final value being copied back to both
SevGuestState::handle and SEVState::handle.
AFAICT, nothing will be looking SEVState::handle before it and
SevGuestState::handle have been updated from the ioctl(). So, remove the
field and just use SevGuestState::handle directly.

Xen PCI passthrough support may not be available and thus the global
variable "has_igd_gfx_passthru" might be compiled out. Common code
should not access it in that case.
Unfortunately, we can't use CONFIG_XEN_PCI_PASSTHROUGH directly in
xen-common.c so this patch instead move access to the
has_igd_gfx_passthru variable via function and those functions are
also implemented as stubs. The stubs will be used when QEMU is built
without passthrough support.
Now, when one will want to enable igd-passthru via the -machine
property, they will get an error message if QEMU is built without
passthrough support.
