6332  *
6333  * 1) Loading CPU model definition (X86CPUDefinition). This is
6334  *    implemented by x86_cpu_load_model() and should be completely
6335  *    transparent, as it is done automatically by instance_init.
6336  *    No code should need to look at X86CPUDefinition structs
6337  *    outside instance_init.
6338  *
6339  * 2) CPU expansion. This is done by realize before CPUID
6340  *    filtering, and will make sure host/accelerator data is
6341  *    loaded for CPU models that depend on host capabilities
6342  *    (e.g. "host"). Done by x86_cpu_expand_features().
6343  *

6345  *    CPUID, and checks if the host supports all capabilities
6346  *    required by the CPU. Runnability of a CPU model is

6349  * Some operations don't require all steps to be performed.
6350  * More precisely:
6351  *
6352  * - CPU instance creation (instance_init) will run only CPU
6353  *   model loading. CPU expansion can't run at instance_init-time
6354  *   because host/accelerator data may be not available yet.
6355  * - CPU realization will perform both CPU model expansion and CPUID
6356  *   filtering, and return an error in case one of them fails.
6357  * - query-cpu-definitions needs to run all 3 steps. It needs
6358  *   to run CPUID filtering, as the 'unavailable-features'
6359  *   field is set based on the filtering results.
6360  * - The query-cpu-model-expansion QMP command only needs to run
6361  *   CPU model loading and CPU expansion. It should not filter
6362  *   any CPUID data based on host capabilities.
