82f76c6702 hw/acpi: extract acpi_add_rom_blob()
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.

e461078163 acpi: pci: use build_append_foo() API to construct MCFG

81c48dd796 hw/i386/acpi: Add object_resolve_type_unambiguous to improve modularity
When building with CONFIG_Q35=n, we get:

    LINK    x86_64-softmmu/qemu-system-x86_64
  /usr/bin/ld: hw/i386/acpi-build.o: in function `acpi_get_misc_info':

  collect2: error: ld returned 1 exit status
  make[1]: *** [Makefile:204: qemu-system-x86_64] Error 1

This is due to a dependency in acpi-build.c on the ICH9_LPC
(via ich9_lpc_find) and PIIX4_PM (via piix4_pm_find) devices.

To allow better modularity (compile acpi-build.c with only
Q35/ICH9 or ISAPC/PIIX4), refactor the similar helper as
object_resolve_type_unambiguous(). This way we relax the
linker dependencies and can build the x86 targets with a
selection of machines (instead of all of them).

9040e6dfa8 i386, acpi: check acpi_memory_hotplug capacity in pre_plug
Currently we do device realization like below:

   hotplug_handler_pre_plug()
   dc->realize()
   hotplug_handler_plug()

Before we do device realization and plug, we should allocate necessary
resources and check if memory-hotplug-support property is enabled.

At the piix4 and ich9, the memory-hotplug-support property is checked at
plug stage. This means that device has been realized and mapped into guest
address space 'pc_dimm_plug()' by the time acpi plug handler is called,
where it might fail and crash QEMU due to reaching g_assert_not_reached()
(piix4) or error_abort (ich9).

Fix it by checking if memory hotplug is enabled at pre_plug stage
where we can gracefully abort hotplug request.

ac6dd31e3f acpi: build TPM Physical Presence interface
The TPM Physical Presence interface consists of an ACPI part, a shared
memory part, and code in the firmware. Users can send messages to the
firmware by writing a code into the shared memory through invoking the
ACPI code. When a reboot happens, the firmware looks for the code and
acts on it by sending sequences of commands to the TPM.

This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't
assume that SMIs are necessary to use. It uses a similar datastructure for
the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use
of it. I extended the shared memory data structure with an array of 256
bytes, one for each code that could be implemented. The array contains
flags describing the individual codes. This decouples the ACPI implementation
from the firmware implementation.

The underlying TCG specification is accessible from the following page.

https://trustedcomputinggroup.org/tcg-physical-presence-interface-specification/

This patch implements version 1.30.

3b97c01e9c tpm: allocate/map buffer for TPM Physical Presence interface
Implement a virtual memory device for the TPM Physical Presence interface.
The memory is located at 0xFED45000 and used by ACPI to send messages to the
firmware (BIOS) and by the firmware to provide parameters for each one of
the supported codes.

This interface should be used by all TPM devices on x86 and can be
added by calling tpm_ppi_init_io().

Note: bios_linker cannot be used to allocate the PPI memory region,
since the reserved memory should stay stable across reboots, and might
be needed before the ACPI tables are installed.

c97adf3ccf pci/pcihp: perform unplug via the hotplug handler
Introduce and use the "unplug" callback.

This is a preparation for multi-stage hotplug handlers, whereby the bus
hotplug handler is overwritten by the machine hotplug handler. This handler
will then pass control to the bus hotplug handler. So to get this running
cleanly, we also have to make sure to go via the hotplug handler chain when
actually unplugging a device after an unplug request. Lookup the hotplug
handler and call "unplug".

tables, we can move it to a generic folder (hw/acpi) and have the i386
ACPI code reuse it in order to reduce code duplication.

a703b4f6c1 hw/arm/virt-acpi-build: Add smmuv3 node in IORT table
This patch builds the smmuv3 node in the ACPI IORT table.

The RID space of the root complex, which spans 0x0-0x10000
maps to streamid space 0x0-0x10000 in smmuv3, which in turn
maps to deviceid space 0x0-0x10000 in the ITS group.

The guest must feature the IOMMU probe deferral series
(https://lkml.org/lkml/2017/4/10/214) which fixes streamid
multiple lookup. This bug is not related to the SMMU emulation.

4ab6cb4c62 tpm: add CRB device
tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB)
Interface as defined in TCG PC Client Platform TPM Profile (PTP)
Specification Family “2.0” Level 00 Revision 01.03 v22.

The PTP allows device implementation to switch between TIS and CRB
model at run time, but given that CRB is a simpler device to
implement, I chose to implement it as a different device.

The device doesn't implement other locality than 0 for now (my laptop
TPM doesn't either, so I assume this isn't so bad)

Tested with some success with Linux upstream and Windows 10, seabios &
modified ovmf. The device is recognized and correctly transmit
command/response with passthrough & emu. However, we are missing PPI
ACPI part atm.

c8389550de vmgenid: replace x-write-pointer-available hack
This compat property sole function is to prevent the device from being
instantiated. Instead of requiring an extra compat property, check if
fw_cfg has DMA enabled.

fw_cfg is a built-in device that is initialized very early by the
machine init code.  We have at least one other device that also
assumes fw_cfg_find() can be safely used on realize: pvpanic.

This has the additional benefit of handling other cases properly, like:

  $ qemu-system-x86_64 -device vmgenid -machine none
  qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide
  $ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.9 -global fw_cfg.dma_enabled=off
  qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide
  $ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.6 -global fw_cfg.dma_enabled=on

cb51ac2ffe hw/arm/virt: generate 64-bit addressable ACPI objects
Our current ACPI table generation code limits the placement of ACPI
tables to 32-bit addressable memory, in order to be able to emit the
root pointer (RSDP) and root table (RSDT) using table types from the
ACPI 1.0 days.

Since ARM was not supported by ACPI before version 5.0, it makes sense
to lift this restriction. This is not crucial for mach-virt, which is
guaranteed to have some memory available below the 4 GB mark, but it
is a nice to have for QEMU machines that do not have any 32-bit
addressable memory, which is not uncommon for real world 64-bit ARM
systems.

Since we already emit a version of the RSDP root pointer that has a
secondary 64-bit wide address field for the 64-bit root table (XSDT),
all we need to do is replace the RSDT generation with the generation
of an XSDT table, and use a different slot in the FADT table to refer
to the DSDT.

77af8a2b95 hw/i386: Use Rev3 FADT (ACPI 2.0) instead of Rev1 to improve guest OS support.
This updates the FADT generated for x86/64 machine types from Revision 1 to 3. (Based on ACPI standard 2.0 instead of 1.0) The intention is to expose the reset register information to guest operating systems which require it, specifically OS X/macOS. Revision 1 FADTs do not contain the fields relating to the reset register.

The new layout and contents remains backwards-compatible with operating systems which only support ACPI 1.0, as the existing fields are not modified by this change, as the 64-bit and 32-bit variants are allowed to co-exist according to the ACPI 2.0 standard. No regressions became apparent in tests with a range of Windows (XP-10) and Linux versions.

The BIOS tables test suite's FADT checksum test has also been updated to reflect the new FADT layout and content.

c7809e6cd7 ACPI: Add vmgenid blob storage to the build tables
This allows them to be centrally initialized and destroyed

The "AcpiBuildTables.vmgenid" array will be used to construct the
"etc/vmgenid_guid" fw_cfg blob.

Its contents will be linked into fw_cfg after being built on the
pc_machine_done() -> acpi_setup() -> acpi_build() call path, and dropped
without use on the subsequent, guest triggered, acpi_build_update() ->
acpi_build() call path.
