The RISC-V KVM driver has its own solution via a KVMCPUConfig struct that has an 'user_set' flag that is set during the Property set() callback. The set() callback also does init() time validations based on the current KVM driver capabilities. For TCG we would want a 'user_set' mechanic too, but we would look ad-hoc via cpu_cfg_ext_auto_update() if a certain extension was user set or not. If we copy what was made in the KVM side we would look for 'user_set' for one into 60+ extension structs spreaded in 3 arrays (riscv_cpu_extensions, riscv_cpu_experimental_exts, riscv_cpu_vendor_exts). We'll still need an extension struct but we won't be using the 'user_set' flag: - 'RISCVCPUMultiExtConfig' will be our specialized structure, similar to wh= at we're already doing with the MISA extensions in 'RISCVCPUMisaExtConfig'. DEFINE_PROP_BOOL() for all 3 extensions arrays were replaced by MULTI_EXT_CFG_BOOL(), a macro that will init our specialized struct; - the 'multi_ext_user_opts' hash will be used to store the offset of each extension that the user set via the set() callback, cpu_set_multi_ext_cfg(). For now we're just initializing and populating it - next patch will use it to determine if a certain extension was user set; - cpu_add_multi_ext_prop() is a new helper that will replace the qdev_property_add_static() calls that our macros are doing to populate user properties. The macro was renamed to ADD_CPU_MULTIEXT_PROPS_ARRAY() for clarity. Note that the non-extension properties in riscv_cpu_options[] still need to be declared via qdev().
