Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.
Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).
This patch allows you to override these default values.
The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN
The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.
Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.
This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

AML needs Address Translation offset to describe how a bridge translates
addresses accross the bridge when using an address descriptor, and
especially on ARM, the translation offset of pio resource is usually
non zero.
Therefore, it's necessary to pass offset for pio, mmio32, mmio64 and bus
number into build_crs.

We introduce a new global flag 'acpi-root-pci-hotplug' for i440fx with which
we can turn on or off PCI device hotplug on the root bus. This flag can be
used to prevent all PCI devices from getting hotplugged or unplugged from the
root PCI bus.
This feature is targetted mostly towards Windows VMs. It is useful in cases
where some hypervisor admins want to deploy guest VMs in a way so that the
users of the guest OSes are not able to hot-eject certain PCI devices from
the Windows system tray. Laine has explained the use case here in detail:
https://www.redhat.com/archives/libvir-list/2020-February/msg00110.html
Julia has resolved this issue for PCIE buses with the following commit:
530a096318 ("pcie_root_port: Add hotplug disabling option")
This commit attempts to introduce similar behavior for PCI root buses used in
i440fx machine types (although in this case, we do not have a per-slot
capability to turn hotplug on or off).
Usage:
-global PIIX4_PM.acpi-root-pci-hotplug=off
By default, this option is enabled which means that hotplug is turned on for
the PCI root bus.
The previously existing flag 'acpi-pci-hotplug-with-bridge-support' for PCI-PCI
bridges remain as is and can be used along with this new flag to control PCI
hotplug on PCI bridges.
This change has been tested using a Windows 2012R2 server guest image and also
with a Windows 2019 server guest image on a Ubuntu 18.04 host using the latest
master qemu from upstream.

The ACPI Generic Event Device (GED) is a hardware-reduced specific
device[ACPI v6.1 Section 5.6.9] that handles all platform events,
including the hotplug ones. This patch generates the AML code that
defines GEDs.
Platforms need to specify their own GED Event bitmap to describe
what kind of events they want to support through GED. Also this
uses a a single interrupt for the GED device, relying on IO
memory region to communicate the type of device affected by the
interrupt. This way, we can support up to 32 events with a unique
interrupt.
This supports only memory hotplug for now.

[ehabkost: include hw/boards.h again to fix build failures]
Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.
While there, delete a few superfluous inclusions of hw/qdev-core.h.
Touching hw/qdev-properties.h now recompiles some 1200 objects.

In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get VMStateDescription. The previous commit made
that unnecessary.
Include migration/vmstate.h only where it's still needed. Touching it
now recompiles only some 1600 objects.

In my "build everything" tree, changing hw/irq.h triggers a recompile
of some 5400 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get qemu_irq and.or qemu_irq_handler.
Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to
qemu/typedefs.h, and then include hw/irq.h only where it's still
needed. Touching it now recompiles only some 500 objects.

Some of the generated qapi-types-MODULE.h are included all over the
place. Changing a QAPI type can trigger massive recompiling. Top
scorers recompile more than 1000 out of some 6600 objects (not
counting tests and objects that don't depend on qemu/osdep.h):
6300 qapi/qapi-builtin-types.h
5700 qapi/qapi-types-run-state.h
3900 qapi/qapi-types-common.h
3300 qapi/qapi-types-sockets.h
3000 qapi/qapi-types-misc.h
3000 qapi/qapi-types-crypto.h
3000 qapi/qapi-types-job.h
3000 qapi/qapi-types-block-core.h
2800 qapi/qapi-types-block.h
1300 qapi/qapi-types-net.h
Clean up headers to include generated QAPI headers only where needed.
Impact is negligible except for hw/qdev-properties.h.
This header includes qapi/qapi-types-block.h and
qapi/qapi-types-misc.h. They are used only in expansions of property
definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and
DEFINE_PROP_OFF_AUTO(). Moving their inclusion from
hw/qdev-properties.h to the users of these macros avoids pointless
recompiles. This is how other property definition macros, such as
DEFINE_PROP_NETDEV(), already work.
Improves things for some of the top scorers:
3600 qapi/qapi-types-common.h
2800 qapi/qapi-types-sockets.h
900 qapi/qapi-types-misc.h
2200 qapi/qapi-types-crypto.h
2100 qapi/qapi-types-job.h
2100 qapi/qapi-types-block-core.h
270 qapi/qapi-types-block.h

Back in 2016, we discussed[1] rules for headers, and these were
generally liked:
1. Have a carefully curated header that's included everywhere first. We
got that already thanks to Peter: osdep.h.
2. Headers should normally include everything they need beyond osdep.h.
If exceptions are needed for some reason, they must be documented in
the header. If all that's needed from a header is typedefs, put
those into qemu/typedefs.h instead of including the header.
3. Cyclic inclusion is forbidden.
This patch gets include/ closer to obeying 2.
It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically. It passes the RFC test there.

arm and i386 has almost the same function acpi_add_rom_blob(), except
giving different FWCfgCallback function.
This patch moves acpi_add_rom_blob() to utils.c by passing
FWCfgCallback to it.

build_append_foo() API doesn't need explicit endianness conversions
which eliminates a source of errors and it makes build_mcfg() look like
declarative definition of MCFG table in ACPI spec, which makes it easy
to review.
