* MachineClass:
* @deprecation_reason: If set, the machine is marked as deprecated. The
* string should provide some clear information about what to use instead.
* @max_cpus: maximum number of CPUs supported. Default: 1
* @min_cpus: minimum number of CPUs supported. Default: 1
* @default_cpus: number of CPUs instantiated if none are specified. Default: 1
* @is_default:
* If true QEMU will use this machine by default if no '-M' option is given.
* @get_hotplug_handler: this function is called during bus-less
* device hotplug. If defined it returns pointer to an instance
* of HotplugHandler object, which handles hotplug operation
* for a given @dev. It may return NULL if @dev doesn't require
* any actions to be performed by hotplug handler.
* @cpu_index_to_instance_props:
* used to provide @cpu_index to socket/core/thread number mapping, allowing
* legacy code to perform mapping from cpu_index to topology properties
* Returns: tuple of socket/core/thread ids given cpu_index belongs to.
* used to provide @cpu_index to socket number mapping, allowing
* a machine to group CPU threads belonging to the same socket/package
* Returns: socket number given cpu_index belongs to.
* @hw_version:
* Value of QEMU_VERSION when the machine was added to QEMU.
* Set only by old machines because they need to keep
* compatibility on code that exposed QEMU_VERSION to guests in
* the past (and now use qemu_hw_version()).
* @possible_cpu_arch_ids:
* Returns an array of @CPUArchId architecture-dependent CPU IDs
* which includes CPU IDs for present and possible to hotplug CPUs.
* Caller is responsible for freeing returned list.
* @get_default_cpu_node_id:
* returns default board specific node_id value for CPU slot specified by
* index @idx in @ms->possible_cpus[]
* @has_hotpluggable_cpus:
* If true, board supports CPUs creation with -device/device_add.
* @default_cpu_type:
* specifies default CPU_TYPE, which will be used for parsing target
* specific features and for creating CPUs if CPU name wasn't provided
* explicitly at CLI
* @minimum_page_bits:
* If non-zero, the board promises never to create a CPU with a page size
* smaller than this, so QEMU can use a more efficient larger page
* size than the target architecture's minimum. (Attempting to create
* such a CPU will fail.) Note that changing this is a migration
* compatibility break for the machine.
* @ignore_memory_transaction_failures:
* If this is flag is true then the CPU will ignore memory transaction
* failures which should cause the CPU to take an exception due to an
* access to an unassigned physical address; the transaction will instead
* return zero (for a read) or be ignored (for a write). This should be
* set only by legacy board models which rely on the old RAZ/WI behaviour
* for handling devices that QEMU does not yet model. New board models
* should instead use "unimplemented-device" for all memory ranges where
* the guest will attempt to probe for a device that QEMU doesn't
* implement and a stub device is required.
* @kvm_type:
* Return the type of KVM corresponding to the kvm-type string option or
* computed based on other criteria such as the host kernel capabilities.
* kvm-type may be NULL if it is not needed.
* @numa_mem_supported:
* true if '--numa node.mem' option is supported and false otherwise
* @hotplug_allowed:
* If the hook is provided, then it'll be called for each device
* hotplug to check whether the device hotplug is allowed. Return
* true to grant allowance or false to reject the hotplug. When
* false is returned, an error must be set to show the reason of
* the rejection. If the hook is not provided, all hotplug will be
* allowed.
* @default_ram_id:
* Specifies initial RAM MemoryRegion name to be used for default backend
* creation if user explicitly hasn't specified backend with "memory-backend"
* property.
* It also will be used as a way to option into "-m" option support.
* If it's not set by board, '-m' will be ignored and generic code will
* not create default RAM MemoryRegion.
* @fixup_ram_size:
* Amends user provided ram size (with -m option) using machine
* specific algorithm. To be used by old machine types for compat
* purposes only.
* Applies only to default memory backend, i.e., explicit memory backend
* wasn't used.
* @smbios_memory_device_size:
* Default size of memory device,
* SMBIOS 3.1.0 "7.18 Memory Device (Type 17)"

* static void MACHINE_VER_SYM(class_init, virt, __VA_ARGS__)( \

* This must be unconditionally used in the register
* method for all machine types which support versioning.
*
* Inijtially it will effectively be a no-op, but after a
* suitable period of time has passed, it will cause
* execution of the method to return, avoiding registration
* of the machine
*
* The new deprecation and deletion policy for versioned
* machine types was introduced in QEMU 9.1.0.
*
* Under the new policy a number of old machine types (any
* prior to 2.12) would be liable for immediate deletion
* which would be a violation of our historical deprecation
* and removal policy
*
* Thus deletions are temporarily gated on existance of
* the env variable "QEMU_DELETE_MACHINES" / QEMU version
* number >= 10.1.0. This gate can be deleted in the 10.1.0
* dev cycle
