4894 *
4895 * When initializing and realizing a CPU object, the steps
4896 * involved in setting up CPUID data are:
4897 *
4898 * 1) Loading CPU model definition (X86CPUDefinition). This is
4899 * implemented by x86_cpu_load_def() and should be completely
4900 * transparent, as it is done automatically by instance_init.
4901 * No code should need to look at X86CPUDefinition structs
4902 * outside instance_init.
4903 *
4904 * 2) CPU expansion. This is done by realize before CPUID
4905 * filtering, and will make sure host/accelerator data is
4906 * loaded for CPU models that depend on host capabilities
4907 * (e.g. "host"). Done by x86_cpu_expand_features().
4908 *
4909 * 3) CPUID filtering. This initializes extra data related to
4910 * CPUID, and checks if the host supports all capabilities
4911 * required by the CPU. Runnability of a CPU model is
4912 * determined at this step. Done by x86_cpu_filter_features().
4913 *
4914 * Some operations don't require all steps to be performed.
4915 * More precisely:
4916 *
4917 * - CPU instance creation (instance_init) will run only CPU
4918 * model loading. CPU expansion can't run at instance_init-time
4919 * because host/accelerator data may be not available yet.
4920 * - CPU realization will perform both CPU model expansion and CPUID
4921 * filtering, and return an error in case one of them fails.
4922 * - query-cpu-definitions needs to run all 3 steps. It needs
4923 * to run CPUID filtering, as the 'unavailable-features'
4924 * field is set based on the filtering results.
4925 * - The query-cpu-model-expansion QMP command only needs to run
4926 * CPU model loading and CPU expansion. It should not filter
4927 * any CPUID data based on host capabilities.
