When running a 32-bit guest, with a e64 vmv.v.x and vl_eq_vlmax set to
true the `tcg_debug_assert(vece <= MO_32)` will be triggered inside
tcg_gen_gvec_dup_i32().
This patch checks that condition and instead uses tcg_gen_gvec_dup_i64()
is required.

Perform the generation of the VIOT ACPI table in 2 separate passes: the first pass
enumerates all of the PCI host bridges and adds the min_bus and max_bus information
to an array.
Once this is done the VIOT table header is generated using the size of the array
to calculate the node count, which means it is no longer necessary to use a
sub-array to hold the PCI host bridge range information along with viommu_off.
Finally the PCI host bridge array is iterated again to add the required entries
to the final VIOT ACPI table.

the code in pcibus_get_fw_dev_path contained the potential for a
stack buffer overflow of 1 byte, potentially writing to the stack an
extra NUL byte.
This overflow could happen if the PCI slot is >= 0x10000000,
and the PCI function is >= 0x10000000, due to the size parameter
of snprintf being incorrectly calculated in the call:
if (PCI_FUNC(d->devfn))
snprintf(path + off, sizeof(path) + off, ",%x", PCI_FUNC(d->devfn));
since the off obtained from a previous call to snprintf is added
instead of subtracted from the total available size of the buffer.
Without the accurate size guard from snprintf, we end up writing in the
worst case:
name (32) + "@" (1) + SLOT (8) + "," (1) + FUNC (8) + term NUL (1) = 51 bytes
In order to provide something more robust, replace all of the code in
pcibus_get_fw_dev_path with a single call to g_strdup_printf,
so there is no need to rely on manual calculations.
Found by compiling QEMU with FORTIFY_SOURCE=3 as the error:
*** buffer overflow detected ***: terminated

As the CXLState will no long be accessible via MachineState
at time of PXB_CXL realization, come back later from the machine specific
code to fill in the missing memory region setup. Only at this stage
is it possible to check if cxl=on, so that check is moved to this
later point.
Note that for multiple host bridges, the allocation order of the
register spaces is changed. This will be reflected in ACPI CEDT.
Stubs are added to handle case of CONFIG_PXB=n for machines that
call these functions.
The bus walking logic is common to all machines so add a utility

Paolo Bonzini requested this change to simplify the ongoing

Includes shortening the command line form cxl-fixed-memory-window
to cxl-fmw as the command lines are extremely long even with this
change.
The json change is needed to ensure that there is
a CXLFixedMemoryWindowOptionsList even though the actual
element in the json is never used. Similar to existing
SgxEpcProperties.
Update qemu-options.hx to reflect that this is now a -machine
parameter. The bulk of -M / -machine parameters are documented
under machine, so use that in preference to M.

replaces adhoc build_isa_devices_aml() with generic AcpiDevAmlIf
way to build bridge AML including all devices that are attached
to its ISA bus.
Later when PCI is converted to AcpiDevAmlIf, build_q35_isa_bridge()
will also be dropped since PCI parts itself will take care of
building device prologue/epilogue AML for each enumerated PCI device.
Expected AML change is contextual, where ISA devices are moved from
separately declared _SB.PCI0.ISA scope, directly under Device(ISA)
node.

by default we do not version ACPI AML as it's considered
a part of firmware. Drop do_not_add_smb_acpi that blocked
SMBUS AML description on 3.1 and older machine types without
providing justification.

convert ad-hoc way we use to generate AML for ISA/SMB IPMI devices
to a generic approach (i.e. make devices provide its own AML blobs
like it is done with other ISA devices (ex. KBD))

wire AcpiDevAmlIf interface to build ich9-smb and its slave
devices AML. It will be used by followup patches to switch
from creating AML in ad-hoc way to a more systematic one
that will scan present devices and ask them to provide
their AML code like it's done with ISA devices.
This patch is a partial conversion, as it only fetches
AML from slave devices attached to its I2C bus.
The conversion will be completed when PCI bus is
switched to use AcpiDevAmlIf and build_smb0() could be
dropped.

smbus-ipmi AML description needs to specify a path to its parent
node in _CRS. The rest of IPMI inplementations (ISA based)
do not need path at all. Instead of passing through a full path
use relative path to point to smbus-ipmi's parent node, it will
let follow up patches to create IPMI device AML in a generic
way instead of current ad-hoc way. (i.e. AML will be generated
the same way it's done for other ISA device, and smbus will be
converted to generate AML for its slave devices the same way
as ISA)
