6260 /***** Steps involved on loading and filtering CPUID data
6262 * When initializing and realizing a CPU object, the steps
6263 * involved in setting up CPUID data are:
6265 * 1) Loading CPU model definition (X86CPUDefinition). This is
6266 * implemented by x86_cpu_load_model() and should be completely
6267 * transparent, as it is done automatically by instance_init.
6268 * No code should need to look at X86CPUDefinition structs
6269 * outside instance_init.
6271 * 2) CPU expansion. This is done by realize before CPUID
6272 * filtering, and will make sure host/accelerator data is
6273 * loaded for CPU models that depend on host capabilities
6274 * (e.g. "host"). Done by x86_cpu_expand_features().
6276 * 3) CPUID filtering. This initializes extra data related to
6277 * CPUID, and checks if the host supports all capabilities
6278 * required by the CPU. Runnability of a CPU model is
6279 * determined at this step. Done by x86_cpu_filter_features().
6281 * Some operations don't require all steps to be performed.
6282 * More precisely:
6284 * - CPU instance creation (instance_init) will run only CPU
6285 * model loading. CPU expansion can't run at instance_init-time
6286 * because host/accelerator data may be not available yet.
6287 * - CPU realization will perform both CPU model expansion and CPUID
6288 * filtering, and return an error in case one of them fails.
6289 * - query-cpu-definitions needs to run all 3 steps. It needs
6290 * to run CPUID filtering, as the 'unavailable-features'
6291 * field is set based on the filtering results.
6292 * - The query-cpu-model-expansion QMP command only needs to run
6293 * CPU model loading and CPU expansion. It should not filter
6294 * any CPUID data based on host capabilities.
