47 * @arch_id - architecture-dependent CPU ID of present or possible CPU
48 * @cpu - pointer to corresponding CPU object if it's present on NULL otherwise
57 * @len - number of @CPUArchId items in @cpus array
58 * @cpus - array of present or possible CPUs for current machine configuration
67 * @get_hotplug_handler: this function is called during bus-less
68 * device hotplug. If defined it returns pointer to an instance
69 * of HotplugHandler object, which handles hotplug operation
70 * for a given @dev. It may return NULL if @dev doesn't require
71 * any actions to be performed by hotplug handler.
72 * @cpu_index_to_socket_id:
73 * used to provide @cpu_index to socket number mapping, allowing
74 * a machine to group CPU threads belonging to the same socket/package
75 * Returns: socket number given cpu_index belongs to.
77 * Value of QEMU_VERSION when the machine was added to QEMU.
78 * Set only by old machines because they need to keep
79 * compatibility on code that exposed QEMU_VERSION to guests in
80 * the past (and now use qemu_hw_version()).
81 * @possible_cpu_arch_ids:
82 * Returns an array of @CPUArchId architecture-dependent CPU IDs
83 * which includes CPU IDs for present and possible to hotplug CPUs.
84 * Caller is responsible for freeing returned list.
85 * @query_hotpluggable_cpus:
86 * Returns a @HotpluggableCPUList, which describes CPUs objects which
87 * could be added with -device/device_add.
88 * Caller is responsible for freeing returned list.
