-/**
- * CPUClass:
- * @class_by_name: Callback to map -cpu command line model name to an
- * instantiatable CPU type.
- * @parse_features: Callback to parse command line arguments.
- * @reset: Callback to reset the #CPUState to its initial state.
- * @reset_dump_flags: #CPUDumpFlags to use for reset logging.
- * @has_work: Callback for checking if there is work to do.
- * @do_interrupt: Callback for interrupt handling.
- * @do_unassigned_access: Callback for unassigned access handling.
- * (this is deprecated: new targets should use do_transaction_failed instead)
- * @do_unaligned_access: Callback for unaligned access handling, if
- * the target defines #ALIGNED_ONLY.
- * @do_transaction_failed: Callback for handling failed memory transactions
- * (ie bus faults or external aborts; not MMU faults)
- * @virtio_is_big_endian: Callback to return %true if a CPU which supports
- * runtime configurable endianness is currently big-endian. Non-configurable
- * CPUs can use the default implementation of this method. This method should
- * not be used by any callers other than the pre-1.0 virtio devices.
- * @memory_rw_debug: Callback for GDB memory access.
- * @dump_state: Callback for dumping state.
- * @dump_statistics: Callback for dumping statistics.
- * @get_arch_id: Callback for getting architecture-dependent CPU ID.
- * @get_paging_enabled: Callback for inquiring whether paging is enabled.
- * @get_memory_mapping: Callback for obtaining the memory mappings.
- * @set_pc: Callback for setting the Program Counter register. This
- *       should have the semantics used by the target architecture when
- *       setting the PC from a source such as an ELF file entry point;
- *       for example on Arm it will also set the Thumb mode bit based
- *       on the least significant bit of the new PC value.
- *       If the target behaviour here is anything other than "set
- *       the PC register to the value passed in" then the target must
- *       also implement the synchronize_from_tb hook.
- * @synchronize_from_tb: Callback for synchronizing state from a TCG
- *       #TranslationBlock. This is called when we abandon execution
- *       of a TB before starting it, and must set all parts of the CPU
- *       state which the previous TB in the chain may not have updated.
- *       This always includes at least the program counter; some targets
- *       will need to do more. If this hook is not implemented then the
- *       default is to call @set_pc(tb->pc).
- * @tlb_fill: Callback for handling a softmmu tlb miss or user-only
- *       address fault.  For system mode, if the access is valid, call
- *       tlb_set_page and return true; if the access is invalid, and
- *       probe is true, return false; otherwise raise an exception and
- *       do not return.  For user-only mode, always raise an exception
- *       and do not return.
- * @get_phys_page_debug: Callback for obtaining a physical address.
- * @get_phys_page_attrs_debug: Callback for obtaining a physical address and the
- *       associated memory transaction attributes to use for the access.
- *       CPUs which use memory transaction attributes should implement this
- *       instead of get_phys_page_debug.
- * @asidx_from_attrs: Callback to return the CPU AddressSpace to use for
- *       a memory access with the specified memory transaction attributes.
- * @gdb_read_register: Callback for letting GDB read a register.
- * @gdb_write_register: Callback for letting GDB write a register.
- * @debug_check_watchpoint: Callback: return true if the architectural
- *       watchpoint whose address has matched should really fire.
- * @debug_excp_handler: Callback for handling debug exceptions.
- * @write_elf64_note: Callback for writing a CPU-specific ELF note to a
- * 64-bit VM coredump.
- * @write_elf32_qemunote: Callback for writing a CPU- and QEMU-specific ELF
- * note to a 32-bit VM coredump.
- * @write_elf32_note: Callback for writing a CPU-specific ELF note to a
- * 32-bit VM coredump.
- * @write_elf32_qemunote: Callback for writing a CPU- and QEMU-specific ELF
- * note to a 32-bit VM coredump.
- * @vmsd: State description for migration.
- * @gdb_num_core_regs: Number of core registers accessible to GDB.
- * @gdb_core_xml_file: File name for core registers GDB XML description.
- * @gdb_stop_before_watchpoint: Indicates whether GDB expects the CPU to stop
- *           before the insn which triggers a watchpoint rather than after it.
- * @gdb_arch_name: Optional callback that returns the architecture name known
- * to GDB. The caller must free the returned string with g_free.
- * @gdb_get_dynamic_xml: Callback to return dynamically generated XML for the
- *   gdb stub. Returns a pointer to the XML contents for the specified XML file
- *   or NULL if the CPU doesn't have a dynamically generated content for it.
- * @cpu_exec_enter: Callback for cpu_exec preparation.
- * @cpu_exec_exit: Callback for cpu_exec cleanup.
- * @cpu_exec_interrupt: Callback for processing interrupts in cpu_exec.
- * @disas_set_info: Setup architecture specific components of disassembly info
- * @adjust_watchpoint_address: Perform a target-specific adjustment to an
- * address before attempting to match it against watchpoints.
- *
- * Represents a CPU family or model.

- * @running: #true if CPU is currently running (lockless).

- * @singlestep_enabled: Flags for single-stepping.
- * @icount_extra: Instructions until next timer event.
- * @can_do_io: Nonzero if memory-mapped IO is safe. Deterministic execution
