4566 *
4567 * When initializing and realizing a CPU object, the steps
4568 * involved in setting up CPUID data are:
4569 *
4570 * 1) Loading CPU model definition (X86CPUDefinition). This is
4571 * implemented by x86_cpu_load_def() and should be completely
4572 * transparent, as it is done automatically by instance_init.
4573 * No code should need to look at X86CPUDefinition structs
4574 * outside instance_init.
4575 *
4576 * 2) CPU expansion. This is done by realize before CPUID
4577 * filtering, and will make sure host/accelerator data is
4578 * loaded for CPU models that depend on host capabilities
4579 * (e.g. "host"). Done by x86_cpu_expand_features().
4580 *
4581 * 3) CPUID filtering. This initializes extra data related to
4582 * CPUID, and checks if the host supports all capabilities
4583 * required by the CPU. Runnability of a CPU model is
4584 * determined at this step. Done by x86_cpu_filter_features().
4585 *
4586 * Some operations don't require all steps to be performed.
4587 * More precisely:
4588 *
4589 * - CPU instance creation (instance_init) will run only CPU
4590 * model loading. CPU expansion can't run at instance_init-time
4591 * because host/accelerator data may be not available yet.
4592 * - CPU realization will perform both CPU model expansion and CPUID
4593 * filtering, and return an error in case one of them fails.
4594 * - query-cpu-definitions needs to run all 3 steps. It needs
4595 * to run CPUID filtering, as the 'unavailable-features'
4596 * field is set based on the filtering results.
4597 * - The query-cpu-model-expansion QMP command only needs to run
4598 * CPU model loading and CPU expansion. It should not filter
4599 * any CPUID data based on host capabilities.
