Alireza Sanaee 98f030e7c9 tests: virt: Update expected ACPI tables for virt test 
Update the ACPI tables according to the acpi aml_build change, also
empty bios-tables-test-allowed-diff.h.

The disassembled differences between actual and expected PPTT shows
below. Only about the root node adding and identification flag set
as expected.

Yicong Yang 9bf96fc2df hw/acpi/aml-build: Build a root node in the PPTT table 
Currently we build the PPTT starting from the socket node and each
socket will be a separate tree. For a multi-socket system it'll
be hard for the OS to know the whole system is homogeneous or not
(actually we're in the current implementation) since no parent node
to telling the identical implementation informentation. Add a
root node for indicating this.

Yicong Yang ec57e4778e hw/acpi/aml-build: Set identical implementation flag for PPTT processor nodes 
Per ACPI 6.5 Table 5.158: Processor Structure Flags, the identical
implementation flag indicates whether all the children processors
of this node share the same identical implementation revision.
Currently Linux support parsing this field [1] and maybe used to
identify the heterogeneous platform. Since qemu only support
homogeneous emulation, set this flag for all the processor node
to indicates the facts when building the PPTT table. Node leaf
is an exception since spec says this flag should be ignored
on leaf nodes by OSPM.

Use a local SysBusDevice handle. Also use the newly introduced
sysbus_mmio_map_name which brings better readability about the region
being mapped. GED device has regions which exist depending on some
external properties and it becomes difficult to guess the index of
a region. Better refer to a region by its name.

Eric Auger 1a10285665 hw/core/sysbus: Introduce sysbus_mmio_map_name() helper 
Some sysbus devices have conditional mmio regions. This
happens for instance with the hw/acpi/ged device. In that case
it becomes difficult to predict which index a specific MMIO
region corresponds to when one needs to mmio map the region.
Introduce a new helper that takes the name of the region instead
of its index. If the region is not found this returns -1.
Otherwise it maps the corresponding index and returns this latter.

Eric Auger 1816a337a1 hw/acpi/ged: Prepare the device to react to PCI hotplug events 
QEMU will notify the OS about PCI hotplug/hotunplug events through
GED interrupts. Let the GED device handle a new PCI hotplug event.
On its occurrence it calls the \\_SB.PCI0.PCNT method with the BLCK
mutex held.

The GED device uses a dedicated MMIO region that will be mapped
by the machine code.

At this point the GED still does not support PCI device hotplug in
its TYPE_HOTPLUG_HANDLER implementation. This will come in a
subsequent patch.

Let pass the root bus to ich9 and piix4 through a property link

Also make sure the root bus is set at the entry of acpi_pcihp_init().

The rationale of that change is to be consistent with the forecoming ARM
implementation where the machine passes the root bus (steming from GPEX)
to the GED device through a link property.

Eric Auger b9dc4e04c8 hw/i386/acpi-build: Use AcpiPciHpState::root in acpi_set_pci_info 
pcihp acpi_set_pci_info() generic code currently uses
acpi_get_i386_pci_host() to retrieve the pci host bridge.

To make it work also on ARM we get rid of that call and
directly use AcpiPciHpState::root.

gpex build_host_bridge_osc() and x86 originated
build_pci_host_bridge_osc_method() are mostly identical.

In GPEX, SUPP is set to CDW2 but is not further used. CTRL
is same as Local0.

So let gpex code reuse build_pci_host_bridge_osc_method()
and remove build_host_bridge_osc().

Also add an imply ACPI_PCI clause along with
PCI_EXPRESS_GENERIC_BRIDGE to compile hw/acpi/pci.c
when its dependency is resolved (ie. CONFIG_ACPI_PCI).
This is requested to link qemu-system-mips64el.

Eric Auger ec9af89198 hw/pci-host/gpex-acpi: Split host bridge OSC and DSM generation 
acpi_dsdt_add_pci_osc() name is confusing as it gives the impression
it appends the _OSC method but in fact it also appends the _DSM method
for the host bridge. Let's split the function into two separate ones
and let them return the method Aml pointer instead. This matches the
way it is done on x86 (build_q35_osc_method). In a subsequent patch
we will replace the gpex method by the q35 implementation that will
become shared between ARM and x86.

acpi_dsdt_add_host_bridge_methods is a new top helper that generates
both the _OSC and _DSM methods.

We take the opportunity to move SUPP and CTRL in the _osc method
that use them.

Philippe Mathieu-Daudé 0af00042a9 qemu/target-info: Factor target_arch() out 
To keep "qemu/target-info.h" self-contained to native
types, declare target_arch() -- which returns a QAPI
type -- in "qemu/target-info-qapi.h".

No logical change.

Keeping native types in "qemu/target-info.h" is necessary
to keep building tests such tests/tcg/plugins/mem.c, as
per the comment added in commit ecbcc9ead2 ("tests/tcg:
add a system test to check memory instrumentation"):

/*
 * plugins should not include anything from QEMU aside from the
 * API header. However as this is a test plugin to exercise the
 * internals of QEMU and we want to avoid needless code duplication we
 * do so here. bswap.h is pretty self-contained although it needs a
 * few things provided by compiler.h.
