Recently MemReentrancyGuard was added to DeviceState to record that the
device is engaging in I/O. The network device backend needs to update it
when delivering a packet to a device.

In preparation for such a change, add MemReentrancyGuard * as a
parameter of qemu_new_nic().

b664466d8f ppc/pnv: Fix PNV I2C invalid status after reset
The PNV I2C Controller was clearing the status register
after a reset without repopulating the "upper threshold
for I2C ports", "Command Complete" and the SCL/SDA input
level fields.

Fixed this for resets caused by a system reset as well
as from writing to the "Immediate Reset" register.

47dfdd238d ppc/pnv: PNV I2C engines assigned incorrect XSCOM addresses
The PNV I2C engines for power9 and power10 were being assigned a base
XSCOM address that was off by one I2C engine's address range such
that engine 0 had engine 1's address and so on.  The xscom address
assignment was being based on the device tree engine numbering, which
starts at 1.  Rather than changing the device tree numbering to start
with 0, the addressing was changed to be based on the existing device
tree numbers minus one.

8bc5ae046d ppc/pnv: Fix potential overflow in I2C model
Coverity warns that "i2c_bus_busy(i2c->busses[i]) << i" might overflow
because the expression is evaluated using 32-bit arithmetic and then
used in a context expecting a uint64_t.

While we are at it, introduce a PNV_I2C_MAX_BUSSES constant and check
the number of busses at realize time.

d652866007 hw/arm/stm32f100: Report error when incorrect CPU is used
The 'stm32vldiscovery' machine ignores the CPU type requested by
the command line. This might confuse users, since the following
will create a machine with a Cortex-M3 CPU:

  $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1

Set the MachineClass::valid_cpu_types field (introduced in commit
c9cf636d48 "machine: Add a valid_cpu_types property").
Remove the now unused MachineClass::default_cpu_type field.

We now get:

  $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1
  qemu-system-aarch64: Invalid CPU type: neoverse-n1-arm-cpu
  The valid types are: cortex-m3-arm-cpu

Since the SoC family can only use Cortex-M3 CPUs, hard-code the
CPU type name at the SoC level, removing the QOM property
entirely.

70726a15bc hw/intc/arm_gicv3: ICC_PMR_EL1 high bits should be RAZ
The ICC_PMR_ELx and ICV_PMR_ELx bit masks returned from
ic{c,v}_fullprio_mask should technically also remove any
bit above 7 as these are marked reserved (read 0) and should
therefore should not be written as anything other than 0.

This was noted during a run of a proprietary test system and
discused on the mailing list [1] and initially thought not to
be an issue due to RES0 being technically allowed to be
written to and read back as long as the implementation does
not use the RES0 bits. It is very possible that the values
are used in comparison without masking, as pointed out by
Peter in [2], if (cs->hppi.prio >= cs->icc_pmr_el1) may well
do the wrong thing.

Masking these values in ic{c,v}_fullprio_mask() should fix
this and prevent any future problems with playing with the
values.

The new SeaBIOS-hppa version 12 includes the necessary fixes to

To boot a 64-bit machine use the "-machine C3700" qemu option.

Something appears to be off between the 64-bit CPU, the 32-bit PDC

power button address in high-mapped firmware memory.

Use a 32-bit value at PAGE0->pad0[4] instead.

1d675e59ea hw/arm/virt: fix GIC maintenance IRQ registration
Since commit 9036e917f8 ("{include/}hw/arm: refactor virt PPI logic"),
GIC maintenance IRQ registration fails on arm64:

[    0.979743] kvm [1]: Cannot register interrupt 9

That commit re-defined VIRTUAL_PMU_IRQ to be a INTID but missed a case
where the maintenance IRQ is actually referred by its PPI index. Just
like commit fa68ecb330 ("hw/arm/virt: fix PMU IRQ registration"), use
INITID_TO_PPI(). A search of "GIC_FDT_IRQ_TYPE_PPI" indicates that there
shouldn't be more similar issues.

Fixes: 9036e917f8 ("{include/}hw/arm: refactor virt PPI logic")

364eff6885 virtio-mem: fix division by zero in virtio_mem_activate_memslots_to_plug()
When running with "dynamic-memslots=off", we enter
virtio_mem_activate_memslots_to_plug() to return immediately again
because "vmem->dynamic_memslots == false". However, the compiler might
not optimize out calculating start_idx+end_idx, where we divide by
vmem->memslot_size. In such a configuration, the memslot size is 0 and
we'll get a division by zero:

    (qemu) qom-set vmem0 requested-size 3G
    (qemu) q35.sh: line 38: 622940 Floating point exception(core dumped)

The same is true for virtio_mem_deactivate_unplugged_memslots(), however
we never really reach that code without a prior
virtio_mem_activate_memslots_to_plug() call.

Let's fix it by simply calling these functions only with
"dynamic-memslots=on".

This was found when using a debug build of QEMU.

d90014fc33 igb: Add Function Level Reset to PF and VF
The Intel 82576EB GbE Controller say that the Physical and Virtual
Functions support Function Level Reset. Add the capability to the PF
device model using device property "x-pcie-flr-init" which is "on" by
default and "off" for machines <= 8.1 to preserve compatibility.

The FLR capability of the VF model is defined according to the FLR
property of the PF, this to avoid adding an extra compatibility
property.

b06f8b500d qdev: Rework array properties based on list visitor
Until now, array properties are actually implemented with a hack that
uses multiple properties on the QOM level: a static "foo-len" property
and after it is set, dynamically created "foo[i]" properties.

In external interfaces (-device on the command line and device_add in
QMP), this interface was broken by commit f3558b1b ('qdev: Base object
creation on QDict rather than QemuOpts') because QDicts are unordered
and therefore it could happen that QEMU tried to set the indexed
properties before setting the length, which fails and effectively makes
array properties inaccessible. In particular, this affects the 'ports'
property of the 'rocker' device, which used to be configured like this:

-device rocker,len-ports=2,ports[0]=dev0,ports[1]=dev1

This patch reworks the external interface so that instead of using a
separate top-level property for the length and for each element, we use
a single true array property that accepts a list value. In the external
interfaces, this is naturally expressed as a JSON list and makes array
properties accessible again. The new syntax looks like this:

-device '{"driver":"rocker","ports":["dev0","dev1"]}'

Creating an array property on the command line without using JSON format
is currently not possible. This could be fixed by switching from
QemuOpts to a keyval parser, which however requires consideration of the
compatibility implications.

All internal users of devices with array properties go through
qdev_prop_set_array() at this point, so updating it takes care of all of
them.

3257b854d8 qdev: Make netdev properties work as list elements
The 'name' parameter of QOM setters is primarily used to specify the name
of the currently parsed input element in the visitor interface. For
top-level qdev properties, this is always set and matches 'prop->name'.

However, for list elements it is NULL, because each element of a list
doesn't have a separate name. Passing a non-NULL value runs into
assertion failures in the visitor code.

Therefore, using 'name' in error messages is not right for property
types that are used in lists, because "(null)" (or even a segfault)
isn't very helpful to identify what QEMU is complaining about.

Change netdev properties to use 'prop->name' instead, which will contain
the name of the array property after switching array properties to lists
in the external interface. (This is still not perfect, as it doesn't
identify which element in the list caused the error, but strictly better
than before.)

b523a3d54f hw/ide/ahci: trigger either error IRQ or regular IRQ, not both
According to AHCI 1.3.1, 5.3.8.1 RegFIS:Entry, if ERR_STAT is set,
we jump to state ERR:FatalTaskfile, which will raise a TFES IRQ
unconditionally, regardless if the I bit is set in the FIS or not.

Thus, we should never raise a normal IRQ after having sent an error
IRQ.

NOTE: for QEMU platforms that use SeaBIOS, this patch depends on QEMU
commit 784155cdcb ("seabios: update submodule to git snapshot"), and
QEMU commit 14f5a7bae4 ("seabios: update binaries to git snapshot"),
which update SeaBIOS to a version that contains SeaBIOS commit 1281e340
("ahci: handle TFES irq correctly").

b4ff21284b cpu: Call plugin hooks only when ready
The initialization and exit hooks will not affect the state of vCPU
outside TCG context, but they may depend on the state of vCPU.
Therefore, it's better to call plugin hooks after the vCPU state is
fully initialized and before it gets uninitialized.
