The new deprecation and deletion policy for versioned machine types is being 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 automatic deletions (by skipping QOM registration) are temporarily gated on existance of the env variable "QEMU_DELETE_MACHINES" / QEMU version number >= 10.1.0. This allows opt-in testing of the automatic deletion logic, while activating it fully in QEMU >= 10.1.0. This whole commit should be reverted in the 10.1.0 dev cycle or shortly thereafter.

* device hotplug. If defined it returns pointer to an instance
|

* for a given @dev. It may return NULL if @dev doesn't require

|
* any actions to be performed by hotplug handler.
|
|

* legacy code to perform mapping from cpu_index to topology properties

* Returns: tuple of socket/core/thread ids given cpu_index belongs to.
|
|

* 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.
