The value cannot in reality exceed MAX_NODES which is currently

hw/acpi: Generic Port Affinity Structure support

These are very similar to the recently added Generic Initiators
but instead of representing an initiator of memory traffic they
represent an edge point beyond which may lie either targets or
initiators. Here we add these ports such that they may
be targets of hmat_lb records to describe the latency and
bandwidth from host side initiators to the port. A discoverable
mechanism such as UEFI CDAT read from CXL devices and switches
is used to discover the remainder of the path, and the OS can build
up full latency and bandwidth numbers as need for work and data
placement decisions.

hw/acpi: Move AML building code for Generic Initiators to aml_build.c

Rather than attempting to create a generic function with mess of the two
different device handle types, use a PCI handle specific variant. If the
ACPI handle form is needed then that can be introduced alongside this
with little duplicated code.

Drop the PCIDeviceHandle in favor of just passing the bus, devfn
and segment directly. devfn kept as a single byte because ARI means
that in this case it is just an 8 bit function number.

hw/acpi/aml-build: Add PPTT table

Add the Processor Properties Topology Table (PPTT) used to
describe CPU topology information to ACPI guests.

Note, a DT-boot Linux guest with a non-flat CPU topology will
see socket and core IDs being sequential integers starting
from zero, which is different from ACPI-boot Linux guest,
e.g. with -smp 4,sockets=2,cores=2,threads=1

a DT boot produces:

cpu: 0 package_id: 0 core_id: 0
cpu: 1 package_id: 0 core_id: 1
cpu: 2 package_id: 1 core_id: 0
cpu: 3 package_id: 1 core_id: 1

an ACPI boot produces:

cpu: 0 package_id: 36 core_id: 0
cpu: 1 package_id: 36 core_id: 1
cpu: 2 package_id: 96 core_id: 2
cpu: 3 package_id: 96 core_id: 3

This is due to several reasons:

1) DT cpu nodes do not have an equivalent field to what the PPTT
ACPI Processor ID must be, i.e. something equal to the MADT CPU
UID or equal to the UID of an ACPI processor container. In both
ACPI cases those are platform dependant IDs assigned by the
vendor.

2) While QEMU is the vendor for a guest, if the topology specifies
SMT (> 1 thread), then, with ACPI, it is impossible to assign a
core-id the same value as a package-id, thus it is not possible
to have package-id=0 and core-id=0. This is because package and
core containers must be in the same ACPI namespace and therefore
must have unique UIDs.

3) ACPI processor containers are not mandatorily required for PPTT
tables to be used and, due to the limitations of which IDs are
selected described above in (2), they are not helpful for QEMU,
so we don't build them with this patch. In the absence of them,
Linux assigns its own unique IDs. The maintainers have chosen not
to use counters from zero, but rather ACPI table offsets, which
explains why the numbers are so much larger than with DT.

4) When there is no SMT (threads=1) the core IDs for ACPI boot guests
match the logical CPU IDs, because these IDs must be equal to the
MADT CPU UID (as no processor containers are present), and QEMU
uses the logical CPU ID for these MADT IDs.

So in summary, with QEMU as the vendor for the guests, we simply
use sequential integers starting from zero for the non-leaf nodes
but with ID-valid flag unset, so that guest will ignore them and
use table offsets as unique container IDs. And we use logical CPU
IDs for the leaf nodes with the ID-valid flag set, which will be
consistent with MADT.

Currently the implementation of PPTT generation complies with ACPI
specification 5.2.29 (Revision 6.3). The 6.3 spec can be found at:

acpi_table_begin():
initializes table header and keeps track of

sets actual table length and tells bios loader
where table is for the later initialization on

acpi: Set proper maximum size for "etc/table-loader" blob

The resizeable memory region / RAMBlock that is created for the cmd blob
has a maximum size of whole host pages (e.g., 4k), because RAMBlocks
work on full host pages. In addition, in i386 ACPI code:
acpi_align_size(tables->linker->cmd_blob, ACPI_BUILD_ALIGN_SIZE);
makes sure to align to multiples of 4k, padding with 0.

For example, if our cmd_blob is created with a size of 2k, the maximum
size is 4k - we cannot grow beyond that. Growing might be required
due to guest action when rebuilding the tables, but also on incoming
migration.

This automatic generation of the maximum size used to be sufficient,
however, there are cases where we cross host pages now when growing at
runtime: we exceed the maximum size of the RAMBlock and can crash QEMU when
trying to resize the resizeable memory region / RAMBlock:
$ build/qemu-system-x86_64 --enable-kvm \
-machine q35,nvdimm=on \
-smp 1 \
-cpu host \
-m size=2G,slots=8,maxmem=4G \
-object memory-backend-file,id=mem0,mem-path=/tmp/nvdimm,size=256M \
-device nvdimm,label-size=131072,memdev=mem0,id=nvdimm0,slot=1 \
-nodefaults \
-device vmgenid \
-device intel-iommu

Results in:
Unexpected error in qemu_ram_resize() at ../softmmu/physmem.c:1850:
qemu-system-x86_64: Size too large: /rom@etc/table-loader:
0x2000 > 0x1000: Invalid argument

In this configuration, we consume exactly 4k (32 entries, 128 bytes each)
when creating the VM. However, once the guest boots up and maps the MCFG,
we also create the MCFG table and end up consuming 2 additional entries
(pointer + checksum) -- which is where we try resizing the memory region
/ RAMBlock, however, the maximum size does not allow for it.

Currently, we get the following maximum sizes for our different
mutable tables based on behavior of resizeable RAMBlock:

hw table max_size
------- ---------------------------------------------------------

virt "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
virt "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
virt "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)

i386 "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
i386 "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)

microvm "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
microvm "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)

Let's set the maximum table size for "etc/table-loader" to 64k, so we
can properly grow at runtime, which should be good enough for the future.

Migration is not concerned with the maximum size of a RAMBlock, only
with the used size - so existing setups are not affected. Of course, we
cannot migrate a VM that would have crash when started on older QEMU from
new QEMU to older QEMU without failing early on the destination when
synchronizing the RAM state:
qemu-system-x86_64: Size too large: /rom@etc/table-loader: 0x2000 > 0x1000: Invalid argument
qemu-system-x86_64: error while loading state for instance 0x0 of device 'ram'
qemu-system-x86_64: load of migration failed: Invalid argument

We'll refactor the code next, to make sure we get rid of this implicit
behavior for "etc/acpi/rsdp" as well and to make the code easier to
grasp.

acpi: Permit OEM ID and OEM table ID fields to be changed

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.
