This reverts commit 2d6cfbaf17.
The patch is supposed to be part of ARM CPU hotplug series and has not value
on its own without it. The series however is still in RFC stage and outside
of scope 9.2 release.
On top of that it introduces not needed callback that pokes directly into
CPU state without any need for that. Instead properties and AML generator
option should be used to configure static platform depended vCPU presence
state.
Drop the patch so that corrected version could be posted along with
ARM CPU hotplug series and properly reviewed in relevant context.
That also helps us to keep history cleaner with new patch being
against original code vs a string of fixups on top of current mess.

Reflect the QOM vCPUs ACPI CPU hotplug states in the `_STA.Present` and
and `_STA.Enabled` bits when the guest kernel evaluates the ACPI
`_STA` method during initialization, as well as when vCPUs are
hot-plugged or hot-unplugged. If the CPU is present then the its
`enabled` status can be fetched using architecture-specific code [1].

On most architectures, during vCPU hot-plug and hot-unplug actions, the
firmware or VMM/QEMU can update the OS on vCPU status by toggling the
ACPI method `_STA.Present` bit. However, certain CPU architectures
prohibit [1] modifications to a CPU’s `presence` status after the kernel
has booted.
This limitation [2][3] exists because many per-CPU components, such as
interrupt controllers and various per-CPU features tightly integrated
with CPUs, may not support reconfiguration once the kernel is
initialized. Often, these components cannot be powered down, as they may
belong to an `always-on` power domain. As a result, some architectures
require all CPUs to remain `_STA.Present` after system initialization.
Therefore, it is essential to mirror the exact QOM vCPU status through
ACPI for the Guest kernel. For this, we should determine—via
architecture-specific code[4]—whether vCPUs must always remain present
and whether the associated `AcpiCpuStatus::cpu` object should remain
valid, even following a vCPU hot-unplug operation.

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.

Whilst ACPI SRAT Generic Initiator Afinity Structures are able to refer to
both PCI and ACPI Device Handles, the QEMU implementation only implements
the PCI Device Handle case. For now move the code into the existing
hw/acpi/pci.c file and header. If support for ACPI Device Handles is

Also push the struct AcpiGenericInitiator down into the c file as not

ACPI GED (as described in the ACPI 6.4 spec) uses an interrupt listed in the
_CRS object of GED to intimate OSPM about an event. Later then demultiplexes the
notified event by evaluating ACPI _EVT method to know the type of event. Use
ACPI GED to also notify the guest kernel about any CPU hot(un)plug events.
Note, GED interface is used by many hotplug events like memory hotplug, NVDIMM
hotplug and non-hotplug events like system power down event. Each of these can
be selected using a bit in the 32 bit GED IO interface. A bit has been reserved
for the CPU hotplug event.
ACPI CPU hotplug related initialization should only happen if ACPI_CPU_HOTPLUG
support has been enabled for particular architecture. Add cpu_hotplug_hw_init()
stub to avoid compilation break.

ACPI spec provides a scheme to associate "Generic Initiators" [1]
(e.g. heterogeneous processors and accelerators, GPUs, and I/O devices with
integrated compute or DMA engines GPUs) with Proximity Domains. This is
achieved using Generic Initiator Affinity Structure in SRAT. During bootup,
Linux kernel parse the ACPI SRAT to determine the PXM ids and create a NUMA
node for each unique PXM ID encountered. Qemu currently do not implement
these structures while building SRAT.
Add GI structures while building VM ACPI SRAT. The association between
device and node are stored using acpi-generic-initiator object. Lookup
presence of all such objects and use them to build these structures.
The structure needs a PCI device handle [2] that consists of the device BDF.
The vfio-pci device corresponding to the acpi-generic-initiator object is
located to determine the BDF.

NVIDIA GPU's support MIG (Mult-Instance GPUs) feature [1], which allows
partitioning of the GPU device resources (including device memory) into
several (upto 8) isolated instances. Each of the partitioned memory needs
a dedicated NUMA node to operate. The partitions are not fixed and they
can be created/deleted at runtime.
Unfortunately Linux OS does not provide a means to dynamically create/destroy
NUMA nodes and such feature implementation is not expected to be trivial. The
nodes that OS discovers at the boot time while parsing SRAT remains fixed. So
we utilize the Generic Initiator (GI) Affinity structures that allows
association between nodes and devices. Multiple GI structures per BDF is
possible, allowing creation of multiple nodes by exposing unique PXM in each
of these structures.
Implement the mechanism to build the GI affinity structures as Qemu currently
does not. Introduce a new acpi-generic-initiator object to allow host admin
link a device with an associated NUMA node. Qemu maintains this association
and use this object to build the requisite GI Affinity Structure.
When multiple NUMA nodes are associated with a device, it is required to
create those many number of acpi-generic-initiator objects, each representing
a unique device:node association.
Following is one of a decoded GI affinity structure in VM ACPI SRAT.

An admin can provide a range of acpi-generic-initiator objects, each
associating a device (by providing the id through pci-dev argument)
to the desired NUMA node (using the node argument). Currently, only PCI
device is supported.
For the grace hopper system, create a range of 8 nodes and associate that
with the device using the acpi-generic-initiator object. While a configuration
of less than 8 nodes per device is allowed, such configuration will prevent
utilization of the feature to the fullest. The following sample creates 8
nodes per PCI device for a VM with 2 PCI devices and link them to the
respecitve PCI device using acpi-generic-initiator objects:

If a vcpu with an apic-id that is not supported by the legacy
interface (>255) is hot-plugged, the legacy code will dynamically switch
to the modern interface. However, the hotplug event is not forwarded to
the new interface resulting in the vcpu not being fully/properly added
to the machine config. This BUG is evidenced by OVMF when it
it attempts to count the vcpus and reports an inconsistent vcpu count
reported by the fw_cfg interface and the modern hotpug interface.
Fix is to propagate the hotplug event after making the switch from
the legacy interface to the modern interface.

Conflicts:
hw/core/machine.c
Context conflict with commit 314e0a84cd ("hw/core: remove needless
includes") because it removed an adjacent #include.
The "hw/boards.h" is unused since the previous commit. Since its removal
requires include fixes in various unrelated files to keep the code compiling it
has been split in a dedicated commit.

This virtual method was always set to the x86-specific pc_madt_cpu_entry(),
even in piix4 which is also used in MIPS. The previous changes use
pc_madt_cpu_entry() otherwise, so madt_cpu can be dropped.
Since pc_madt_cpu_entry() is now only used in x86-specific code, the stub
in hw/acpi/acpi-x86-stub can be removed as well.

build_cpus_aml() is architecture independent but needs to create architecture-
specific CPU AML. So far this was achieved by using a virtual method from
TYPE_ACPI_DEVICE_IF. However, build_cpus_aml() would resolve this interface from
global (!) state. This makes it quite incomprehensible where this interface
comes from (TYPE_PIIX4_PM?, TYPE_ICH9_LPC_DEVICE?, TYPE_ACPI_GED_X86?) an can
lead to crashes when the generic code is ported to new architectures.
So far, build_cpus_aml() is only called in architecture-specific code -- and
only in x86. We can therefore simply pass pc_madt_cpu_entry() as callback to
build_cpus_aml(). This is the same callback that would be used through
TYPE_ACPI_DEVICE_IF.
