3456 *
3457 * When initializing and realizing a CPU object, the steps
3458 * involved in setting up CPUID data are:
3459 *
3460 * 1) Loading CPU model definition (X86CPUDefinition). This is
3461 * implemented by x86_cpu_load_def() and should be completely
3462 * transparent, as it is done automatically by instance_init.
3463 * No code should need to look at X86CPUDefinition structs
3464 * outside instance_init.
3465 *
3466 * 2) CPU expansion. This is done by realize before CPUID
3467 * filtering, and will make sure host/accelerator data is
3468 * loaded for CPU models that depend on host capabilities
3469 * (e.g. "host"). Done by x86_cpu_expand_features().
3470 *
3471 * 3) CPUID filtering. This initializes extra data related to
3472 * CPUID, and checks if the host supports all capabilities
3473 * required by the CPU. Runnability of a CPU model is
3474 * determined at this step. Done by x86_cpu_filter_features().
3475 *
3476 * Some operations don't require all steps to be performed.
3477 * More precisely:
3478 *
3479 * - CPU instance creation (instance_init) will run only CPU
3480 * model loading. CPU expansion can't run at instance_init-time
3481 * because host/accelerator data may be not available yet.
3482 * - CPU realization will perform both CPU model expansion and CPUID
3483 * filtering, and return an error in case one of them fails.
3484 * - query-cpu-definitions needs to run all 3 steps. It needs
3485 * to run CPUID filtering, as the 'unavailable-features'
3486 * field is set based on the filtering results.
3487 * - The query-cpu-model-expansion QMP command only needs to run
3488 * CPU model loading and CPU expansion. It should not filter
3489 * any CPUID data based on host capabilities.
