4724 *
4725 * When initializing and realizing a CPU object, the steps
4726 * involved in setting up CPUID data are:
4727 *
4728 * 1) Loading CPU model definition (X86CPUDefinition). This is
4729 * implemented by x86_cpu_load_def() and should be completely
4730 * transparent, as it is done automatically by instance_init.
4731 * No code should need to look at X86CPUDefinition structs
4732 * outside instance_init.
4733 *
4734 * 2) CPU expansion. This is done by realize before CPUID
4735 * filtering, and will make sure host/accelerator data is
4736 * loaded for CPU models that depend on host capabilities
4737 * (e.g. "host"). Done by x86_cpu_expand_features().
4738 *
4739 * 3) CPUID filtering. This initializes extra data related to
4740 * CPUID, and checks if the host supports all capabilities
4741 * required by the CPU. Runnability of a CPU model is
4742 * determined at this step. Done by x86_cpu_filter_features().
4743 *
4744 * Some operations don't require all steps to be performed.
4745 * More precisely:
4746 *
4747 * - CPU instance creation (instance_init) will run only CPU
4748 * model loading. CPU expansion can't run at instance_init-time
4749 * because host/accelerator data may be not available yet.
4750 * - CPU realization will perform both CPU model expansion and CPUID
4751 * filtering, and return an error in case one of them fails.
4752 * - query-cpu-definitions needs to run all 3 steps. It needs
4753 * to run CPUID filtering, as the 'unavailable-features'
4754 * field is set based on the filtering results.
4755 * - The query-cpu-model-expansion QMP command only needs to run
4756 * CPU model loading and CPU expansion. It should not filter
4757 * any CPUID data based on host capabilities.
