4583 *
4584 * When initializing and realizing a CPU object, the steps
4585 * involved in setting up CPUID data are:
4586 *
4587 * 1) Loading CPU model definition (X86CPUDefinition). This is
4588 * implemented by x86_cpu_load_def() and should be completely
4589 * transparent, as it is done automatically by instance_init.
4590 * No code should need to look at X86CPUDefinition structs
4591 * outside instance_init.
4592 *
4593 * 2) CPU expansion. This is done by realize before CPUID
4594 * filtering, and will make sure host/accelerator data is
4595 * loaded for CPU models that depend on host capabilities
4596 * (e.g. "host"). Done by x86_cpu_expand_features().
4597 *
4598 * 3) CPUID filtering. This initializes extra data related to
4599 * CPUID, and checks if the host supports all capabilities

4606 * - CPU instance creation (instance_init) will run only CPU
4607 * model loading. CPU expansion can't run at instance_init-time
4608 * because host/accelerator data may be not available yet.
4609 * - CPU realization will perform both CPU model expansion and CPUID
4610 * filtering, and return an error in case one of them fails.
4611 * - query-cpu-definitions needs to run all 3 steps. It needs
4612 * to run CPUID filtering, as the 'unavailable-features'
4613 * field is set based on the filtering results.
4614 * - The query-cpu-model-expansion QMP command only needs to run
4615 * CPU model loading and CPU expansion. It should not filter
4616 * any CPUID data based on host capabilities.
