74 | * @deprecation_reason: If set, the machine is marked as deprecated. The |
75 | * string should provide some clear information about what to use instead. | |
72649619 EC |
76 | * @max_cpus: maximum number of CPUs supported. Default: 1 |
77 | * @min_cpus: minimum number of CPUs supported. Default: 1 | |
78 | * @default_cpus: number of CPUs instantiated if none are specified. Default: 1 | |
ea0ac7f6 PMD |
79 | * @is_default: |
80 | * If true QEMU will use this machine by default if no '-M' option is given. | |
b7454548 IM |
81 | * @get_hotplug_handler: this function is called during bus-less |
82 | * device hotplug. If defined it returns pointer to an instance | |
83 | * of HotplugHandler object, which handles hotplug operation | |
84 | * for a given @dev. It may return NULL if @dev doesn't require | |
85 | * any actions to be performed by hotplug handler. | |
ea089eeb IM |
86 | * @cpu_index_to_instance_props: |
87 | * used to provide @cpu_index to socket/core/thread number mapping, allowing | |
88 | * legacy code to perform maping from cpu_index to topology properties | |
89 | * Returns: tuple of socket/core/thread ids given cpu_index belongs to. | |
57924bcd IM |
90 | * used to provide @cpu_index to socket number mapping, allowing |
91 | * a machine to group CPU threads belonging to the same socket/package | |
92 | * Returns: socket number given cpu_index belongs to. | |
fac862ff EH |
93 | * @hw_version: |
94 | * Value of QEMU_VERSION when the machine was added to QEMU. | |
95 | * Set only by old machines because they need to keep | |
96 | * compatibility on code that exposed QEMU_VERSION to guests in | |
97 | * the past (and now use qemu_hw_version()). | |
3811ef14 IM |
98 | * @possible_cpu_arch_ids: |
99 | * Returns an array of @CPUArchId architecture-dependent CPU IDs | |
100 | * which includes CPU IDs for present and possible to hotplug CPUs. | |
101 | * Caller is responsible for freeing returned list. | |
79e07936 IM |
102 | * @get_default_cpu_node_id: |
103 | * returns default board specific node_id value for CPU slot specified by | |
104 | * index @idx in @ms->possible_cpus[] | |
c5514d0e IM |
105 | * @has_hotpluggable_cpus: |
106 | * If true, board supports CPUs creation with -device/device_add. | |
6063d4c0 IM |
107 | * @default_cpu_type: |
108 | * specifies default CPU_TYPE, which will be used for parsing target | |
109 | * specific features and for creating CPUs if CPU name wasn't provided | |
110 | * explicitly at CLI | |
20bccb82 PM |
111 | * @minimum_page_bits: |
112 | * If non-zero, the board promises never to create a CPU with a page size | |
113 | * smaller than this, so QEMU can use a more efficient larger page | |
114 | * size than the target architecture's minimum. (Attempting to create | |
115 | * such a CPU will fail.) Note that changing this is a migration | |
116 | * compatibility break for the machine. | |
ed860129 PM |
117 | * @ignore_memory_transaction_failures: |
118 | * If this is flag is true then the CPU will ignore memory transaction | |
119 | * failures which should cause the CPU to take an exception due to an | |
120 | * access to an unassigned physical address; the transaction will instead | |
121 | * return zero (for a read) or be ignored (for a write). This should be | |
122 | * set only by legacy board models which rely on the old RAZ/WI behaviour | |
123 | * for handling devices that QEMU does not yet model. New board models | |
124 | * should instead use "unimplemented-device" for all memory ranges where | |
125 | * the guest will attempt to probe for a device that QEMU doesn't | |
126 | * implement and a stub device is required. | |
dc0ca80e EA |
127 | * @kvm_type: |
128 | * Return the type of KVM corresponding to the kvm-type string option or | |
129 | * computed based on other criteria such as the host kernel capabilities. | |
cd5ff833 IM |
130 | * @numa_mem_supported: |
131 | * true if '--numa node.mem' option is supported and false otherwise | |
6f479566 LX |
132 | * @smp_parse: |
133 | * The function pointer to hook different machine specific functions for | |
134 | * parsing "smp-opts" from QemuOpts to MachineState::CpuTopology and more | |
135 | * machine specific topology fields, such as smp_dies for PCMachine. | |
d2321d31 PX |
136 | * @hotplug_allowed: |
137 | * If the hook is provided, then it'll be called for each device | |
138 | * hotplug to check whether the device hotplug is allowed. Return | |
139 | * true to grant allowance or false to reject the hotplug. When | |
140 | * false is returned, an error must be set to show the reason of | |
141 | * the rejection. If the hook is not provided, all hotplug will be | |
142 | * allowed. | |
900c0ba3 IM |
143 | * @default_ram_id: |
144 | * Specifies inital RAM MemoryRegion name to be used for default backend | |
145 | * creation if user explicitly hasn't specified backend with "memory-backend" | |
146 | * property. | |
147 | * It also will be used as a way to optin into "-m" option support. | |
148 | * If it's not set by board, '-m' will be ignored and generic code will | |
149 | * not create default RAM MemoryRegion. | |
5c30ef93 CB |
150 | * @fixup_ram_size: |
151 | * Amends user provided ram size (with -m option) using machine | |
152 | * specific algorithm. To be used by old machine types for compat | |
153 | * purposes only. | |
154 | * Applies only to default memory backend, i.e., explicit memory backend | |
155 | * wasn't used. | |
