6315 *
6316 * When initializing and realizing a CPU object, the steps
6317 * involved in setting up CPUID data are:
6318 *
6319 * 1) Loading CPU model definition (X86CPUDefinition). This is
6320 * implemented by x86_cpu_load_model() and should be completely
6321 * transparent, as it is done automatically by instance_init.
6322 * No code should need to look at X86CPUDefinition structs
6323 * outside instance_init.
6324 *
6325 * 2) CPU expansion. This is done by realize before CPUID
6326 * filtering, and will make sure host/accelerator data is
6327 * loaded for CPU models that depend on host capabilities
6328 * (e.g. "host"). Done by x86_cpu_expand_features().
6329 *
6330 * 3) CPUID filtering. This initializes extra data related to
6331 * CPUID, and checks if the host supports all capabilities
6332 * required by the CPU. Runnability of a CPU model is
6333 * determined at this step. Done by x86_cpu_filter_features().
6334 *
6335 * Some operations don't require all steps to be performed.
6336 * More precisely:
6337 *
6338 * - CPU instance creation (instance_init) will run only CPU
6339 * model loading. CPU expansion can't run at instance_init-time
6340 * because host/accelerator data may be not available yet.
6341 * - CPU realization will perform both CPU model expansion and CPUID
6342 * filtering, and return an error in case one of them fails.
6343 * - query-cpu-definitions needs to run all 3 steps. It needs
6344 * to run CPUID filtering, as the 'unavailable-features'
6345 * field is set based on the filtering results.
6346 * - The query-cpu-model-expansion QMP command only needs to run
6347 * CPU model loading and CPU expansion. It should not filter
6348 * any CPUID data based on host capabilities.
