4926 /***** Steps involved on loading and filtering CPUID data
4927  *
4928  * When initializing and realizing a CPU object, the steps
4929  * involved in setting up CPUID data are:
4930  *
4931  * 1) Loading CPU model definition (X86CPUDefinition). This is
4932  *    implemented by x86_cpu_load_def() and should be completely
4933  *    transparent, as it is done automatically by instance_init.
4934  *    No code should need to look at X86CPUDefinition structs
4935  *    outside instance_init.
4936  *
4937  * 2) CPU expansion. This is done by realize before CPUID
4938  *    filtering, and will make sure host/accelerator data is
4939  *    loaded for CPU models that depend on host capabilities
4940  *    (e.g. "host"). Done by x86_cpu_expand_features().
4941  *
4942  * 3) CPUID filtering. This initializes extra data related to
4943  *    CPUID, and checks if the host supports all capabilities
4944  *    required by the CPU. Runnability of a CPU model is
4945  *    determined at this step. Done by x86_cpu_filter_features().
4946  *
4947  * Some operations don't require all steps to be performed.
4948  * More precisely:
4949  *
4950  * - CPU instance creation (instance_init) will run only CPU
4951  *   model loading. CPU expansion can't run at instance_init-time
4952  *   because host/accelerator data may be not available yet.
4953  * - CPU realization will perform both CPU model expansion and CPUID
4954  *   filtering, and return an error in case one of them fails.
4955  * - query-cpu-definitions needs to run all 3 steps. It needs
4956  *   to run CPUID filtering, as the 'unavailable-features'
4957  *   field is set based on the filtering results.
4958  * - The query-cpu-model-expansion QMP command only needs to run
4959  *   CPU model loading and CPU expansion. It should not filter
4960  *   any CPUID data based on host capabilities.
