charset="utf-8" All machines that support user specified cpu_model either call cpu_generic_init() or cpu_class_by_name()/CPUClass::parse_features to parse feature string and to get CPU type to create. Which leads to code duplication and hard-codding default CPU model within machine_foo_init() code. Which makes it impossible to get CPU type before machine_init() is run. So instead of setting default CPUs models and doing parsing in target specific machine_foo_init() in various ways, provide a generic data driven cpu_model parsing before machine_init() is called. in follow up per target patches, it will allow to: * define default CPU type in consistent/generic manner per machine type and drop custom code that fallbacks to default if cpu_model is NULL * drop custom features parsing in targets and do it in centralized way. * for cases of cpu_generic_init(TYPE_BASE/DEFAULT_CPU, "some_cpu") replace it with cpu_create(machine->cpu_type) || cpu_create(TYPE_FOO) depending if CPU type is user settable or not. not doing useless parsing and clearly documenting where CPU model is user settable or fixed one. Patch allows machine subclasses to define default CPU type per machine class at class_init() time and if that is set generic code will parse cpu_model into a MachineState::cpu_type which will be used to create CPUs for that machine instance and allows gradual per board conversion.

For the 2nd 1: set default cpu type with MachineClass::default_cpu_type and 2: use generic cpu_model parsing that done before machine_init() is run and: 2.1: drop custom cpu_model parsing where pattern is: typename =3D object_class_get_name( cpu_class_by_name(TYPE_ARM_CPU, cpu_model)) [parse_features(typename, cpu_model, &err) ] 2.2: or replace cpu_generic_init() which does what 2.1 does + create_cpu(typename) with just create_cpu(machine->cpu_type) as result cpu_name -> cpu_type translation is done using generic machine code one including parsing optional features if supported/present (removes a bunch of duplicated cpu_model parsing code) and default cpu type is defined in an uniform way within machine_class_init callbacks instead of adhoc places in boadr's machine_init code.
