4939 * 1) Loading CPU model definition (X86CPUDefinition). This is
4940 * implemented by x86_cpu_load_def() and should be completely
4941 * transparent, as it is done automatically by instance_init.
4942 * No code should need to look at X86CPUDefinition structs
4943 * outside instance_init.
4945 * 2) CPU expansion. This is done by realize before CPUID
4946 * filtering, and will make sure host/accelerator data is
4947 * loaded for CPU models that depend on host capabilities
4948 * (e.g. "host"). Done by x86_cpu_expand_features().
4950 * 3) CPUID filtering. This initializes extra data related to
4951 * CPUID, and checks if the host supports all capabilities
4952 * required by the CPU. Runnability of a CPU model is
4953 * determined at this step. Done by x86_cpu_filter_features().
4955 * Some operations don't require all steps to be performed.
4958 * - CPU instance creation (instance_init) will run only CPU
4959 * model loading. CPU expansion can't run at instance_init-time
4960 * because host/accelerator data may be not available yet.
4961 * - CPU realization will perform both CPU model expansion and CPUID
4962 * filtering, and return an error in case one of them fails.
4963 * - query-cpu-definitions needs to run all 3 steps. It needs
4964 * to run CPUID filtering, as the 'unavailable-features'
4965 * field is set based on the filtering results.
4966 * - The query-cpu-model-expansion QMP command only needs to run
4967 * CPU model loading and CPU expansion. It should not filter
4968 * any CPUID data based on host capabilities.
