6336 * When initializing and realizing a CPU object, the steps
6337 * involved in setting up CPUID data are:
6339 * 1) Loading CPU model definition (X86CPUDefinition). This is
6340 * implemented by x86_cpu_load_model() and should be completely
6341 * transparent, as it is done automatically by instance_init.
6342 * No code should need to look at X86CPUDefinition structs
6343 * outside instance_init.
6345 * 2) CPU expansion. This is done by realize before CPUID
6346 * filtering, and will make sure host/accelerator data is
6347 * loaded for CPU models that depend on host capabilities
6348 * (e.g. "host"). Done by x86_cpu_expand_features().
6350 * 3) CPUID filtering. This initializes extra data related to
6351 * CPUID, and checks if the host supports all capabilities
6352 * required by the CPU. Runnability of a CPU model is
6353 * determined at this step. Done by x86_cpu_filter_features().
6355 * Some operations don't require all steps to be performed.
6358 * - CPU instance creation (instance_init) will run only CPU
6359 * model loading. CPU expansion can't run at instance_init-time
6360 * because host/accelerator data may be not available yet.
6361 * - CPU realization will perform both CPU model expansion and CPUID
6362 * filtering, and return an error in case one of them fails.
6363 * - query-cpu-definitions needs to run all 3 steps. It needs
6364 * to run CPUID filtering, as the 'unavailable-features'
6365 * field is set based on the filtering results.
6366 * - The query-cpu-model-expansion QMP command only needs to run
6367 * CPU model loading and CPU expansion. It should not filter
6368 * any CPUID data based on host capabilities.
