3942 *
3943 * When initializing and realizing a CPU object, the steps
3944 * involved in setting up CPUID data are:
3945 *
3946 * 1) Loading CPU model definition (X86CPUDefinition). This is
3947 * implemented by x86_cpu_load_def() and should be completely
3948 * transparent, as it is done automatically by instance_init.
3949 * No code should need to look at X86CPUDefinition structs
3950 * outside instance_init.
3951 *
3952 * 2) CPU expansion. This is done by realize before CPUID
3953 * filtering, and will make sure host/accelerator data is
3954 * loaded for CPU models that depend on host capabilities
3955 * (e.g. "host"). Done by x86_cpu_expand_features().
3956 *
3957 * 3) CPUID filtering. This initializes extra data related to
3958 * CPUID, and checks if the host supports all capabilities
3959 * required by the CPU. Runnability of a CPU model is
3960 * determined at this step. Done by x86_cpu_filter_features().
3961 *
3962 * Some operations don't require all steps to be performed.
3963 * More precisely:
3964 *
3965 * - CPU instance creation (instance_init) will run only CPU
3966 * model loading. CPU expansion can't run at instance_init-time
3967 * because host/accelerator data may be not available yet.
3968 * - CPU realization will perform both CPU model expansion and CPUID
3969 * filtering, and return an error in case one of them fails.
3970 * - query-cpu-definitions needs to run all 3 steps. It needs
3971 * to run CPUID filtering, as the 'unavailable-features'
3972 * field is set based on the filtering results.
3973 * - The query-cpu-model-expansion QMP command only needs to run
3974 * CPU model loading and CPU expansion. It should not filter
3975 * any CPUID data based on host capabilities.
