6129 /***** Steps involved on loading and filtering CPUID data
6130  *
6131  * When initializing and realizing a CPU object, the steps
6132  * involved in setting up CPUID data are:
6133  *
6134  * 1) Loading CPU model definition (X86CPUDefinition). This is
6135  *    implemented by x86_cpu_load_model() and should be completely
6136  *    transparent, as it is done automatically by instance_init.
6137  *    No code should need to look at X86CPUDefinition structs
6138  *    outside instance_init.
6139  *
6140  * 2) CPU expansion. This is done by realize before CPUID
6141  *    filtering, and will make sure host/accelerator data is
6142  *    loaded for CPU models that depend on host capabilities
6143  *    (e.g. "host"). Done by x86_cpu_expand_features().
6144  *
6145  * 3) CPUID filtering. This initializes extra data related to
6146  *    CPUID, and checks if the host supports all capabilities
6147  *    required by the CPU. Runnability of a CPU model is
6148  *    determined at this step. Done by x86_cpu_filter_features().
6149  *
6150  * Some operations don't require all steps to be performed.
6151  * More precisely:
6152  *
6153  * - CPU instance creation (instance_init) will run only CPU
6154  *   model loading. CPU expansion can't run at instance_init-time
6155  *   because host/accelerator data may be not available yet.
6156  * - CPU realization will perform both CPU model expansion and CPUID
6157  *   filtering, and return an error in case one of them fails.
6158  * - query-cpu-definitions needs to run all 3 steps. It needs
6159  *   to run CPUID filtering, as the 'unavailable-features'
6160  *   field is set based on the filtering results.
6161  * - The query-cpu-model-expansion QMP command only needs to run
6162  *   CPU model loading and CPU expansion. It should not filter
6163  *   any CPUID data based on host capabilities.
