4727 *
4728 * When initializing and realizing a CPU object, the steps
4729 * involved in setting up CPUID data are:
4730 *
4731 * 1) Loading CPU model definition (X86CPUDefinition). This is
4732 * implemented by x86_cpu_load_def() and should be completely
4733 * transparent, as it is done automatically by instance_init.
4734 * No code should need to look at X86CPUDefinition structs
4735 * outside instance_init.
4736 *
4737 * 2) CPU expansion. This is done by realize before CPUID
4738 * filtering, and will make sure host/accelerator data is
4739 * loaded for CPU models that depend on host capabilities
4740 * (e.g. "host"). Done by x86_cpu_expand_features().
4741 *
4742 * 3) CPUID filtering. This initializes extra data related to
4743 * CPUID, and checks if the host supports all capabilities
4744 * required by the CPU. Runnability of a CPU model is
4745 * determined at this step. Done by x86_cpu_filter_features().
4746 *
4747 * Some operations don't require all steps to be performed.
4748 * More precisely:
4749 *
4750 * - CPU instance creation (instance_init) will run only CPU
4751 * model loading. CPU expansion can't run at instance_init-time
4752 * because host/accelerator data may be not available yet.
4753 * - CPU realization will perform both CPU model expansion and CPUID
4754 * filtering, and return an error in case one of them fails.
4755 * - query-cpu-definitions needs to run all 3 steps. It needs
4756 * to run CPUID filtering, as the 'unavailable-features'
4757 * field is set based on the filtering results.
4758 * - The query-cpu-model-expansion QMP command only needs to run
4759 * CPU model loading and CPU expansion. It should not filter
4760 * any CPUID data based on host capabilities.
