4983 *
4984 * When initializing and realizing a CPU object, the steps
4985 * involved in setting up CPUID data are:
4986 *
4987 * 1) Loading CPU model definition (X86CPUDefinition). This is
4988 * implemented by x86_cpu_load_def() and should be completely
4989 * transparent, as it is done automatically by instance_init.
4990 * No code should need to look at X86CPUDefinition structs
4991 * outside instance_init.
4992 *
4993 * 2) CPU expansion. This is done by realize before CPUID
4994 * filtering, and will make sure host/accelerator data is
4995 * loaded for CPU models that depend on host capabilities
4996 * (e.g. "host"). Done by x86_cpu_expand_features().
4997 *
4998 * 3) CPUID filtering. This initializes extra data related to
4999 * CPUID, and checks if the host supports all capabilities
5000 * required by the CPU. Runnability of a CPU model is
5001 * determined at this step. Done by x86_cpu_filter_features().
5002 *
5003 * Some operations don't require all steps to be performed.
5004 * More precisely:
5005 *
5006 * - CPU instance creation (instance_init) will run only CPU
5007 * model loading. CPU expansion can't run at instance_init-time
5008 * because host/accelerator data may be not available yet.
5009 * - CPU realization will perform both CPU model expansion and CPUID
5010 * filtering, and return an error in case one of them fails.
5011 * - query-cpu-definitions needs to run all 3 steps. It needs
5012 * to run CPUID filtering, as the 'unavailable-features'
5013 * field is set based on the filtering results.
5014 * - The query-cpu-model-expansion QMP command only needs to run
5015 * CPU model loading and CPU expansion. It should not filter
5016 * any CPUID data based on host capabilities.
