6254  *
6255  * When initializing and realizing a CPU object, the steps
6256  * involved in setting up CPUID data are:
6257  *
6258  * 1) Loading CPU model definition (X86CPUDefinition). This is
6259  *    implemented by x86_cpu_load_model() and should be completely
6260  *    transparent, as it is done automatically by instance_init.
6261  *    No code should need to look at X86CPUDefinition structs
6262  *    outside instance_init.
6263  *
6264  * 2) CPU expansion. This is done by realize before CPUID
6265  *    filtering, and will make sure host/accelerator data is
6266  *    loaded for CPU models that depend on host capabilities
6267  *    (e.g. "host"). Done by x86_cpu_expand_features().
6268  *
6269  * 3) CPUID filtering. This initializes extra data related to
6270  *    CPUID, and checks if the host supports all capabilities
6271  *    required by the CPU. Runnability of a CPU model is
6272  *    determined at this step. Done by x86_cpu_filter_features().
6273  *
6274  * Some operations don't require all steps to be performed.
6275  * More precisely:
6276  *
6277  * - CPU instance creation (instance_init) will run only CPU
6278  *   model loading. CPU expansion can't run at instance_init-time
6279  *   because host/accelerator data may be not available yet.
6280  * - CPU realization will perform both CPU model expansion and CPUID
6281  *   filtering, and return an error in case one of them fails.
6282  * - query-cpu-definitions needs to run all 3 steps. It needs
6283  *   to run CPUID filtering, as the 'unavailable-features'
6284  *   field is set based on the filtering results.
6285  * - The query-cpu-model-expansion QMP command only needs to run
6286  *   CPU model loading and CPU expansion. It should not filter
6287  *   any CPUID data based on host capabilities.
