5098 *
5099 * When initializing and realizing a CPU object, the steps
5100 * involved in setting up CPUID data are:
5101 *
5102 * 1) Loading CPU model definition (X86CPUDefinition). This is
5103 * implemented by x86_cpu_load_def() and should be completely
5104 * transparent, as it is done automatically by instance_init.
5105 * No code should need to look at X86CPUDefinition structs
5106 * outside instance_init.
5107 *
5108 * 2) CPU expansion. This is done by realize before CPUID
5109 * filtering, and will make sure host/accelerator data is
5110 * loaded for CPU models that depend on host capabilities
5111 * (e.g. "host"). Done by x86_cpu_expand_features().
5112 *
5113 * 3) CPUID filtering. This initializes extra data related to
5114 * CPUID, and checks if the host supports all capabilities
5115 * required by the CPU. Runnability of a CPU model is
5116 * determined at this step. Done by x86_cpu_filter_features().
5117 *
5118 * Some operations don't require all steps to be performed.
5119 * More precisely:
5120 *
5121 * - CPU instance creation (instance_init) will run only CPU
5122 * model loading. CPU expansion can't run at instance_init-time
5123 * because host/accelerator data may be not available yet.
5124 * - CPU realization will perform both CPU model expansion and CPUID
5125 * filtering, and return an error in case one of them fails.
5126 * - query-cpu-definitions needs to run all 3 steps. It needs
5127 * to run CPUID filtering, as the 'unavailable-features'
5128 * field is set based on the filtering results.
5129 * - The query-cpu-model-expansion QMP command only needs to run
5130 * CPU model loading and CPU expansion. It should not filter
5131 * any CPUID data based on host capabilities.
