6122 *
6123 * When initializing and realizing a CPU object, the steps
6124 * involved in setting up CPUID data are:
6125 *
6126 * 1) Loading CPU model definition (X86CPUDefinition). This is
6127 * implemented by x86_cpu_load_model() and should be completely
6128 * transparent, as it is done automatically by instance_init.
6129 * No code should need to look at X86CPUDefinition structs
6130 * outside instance_init.
6131 *
6132 * 2) CPU expansion. This is done by realize before CPUID
6133 * filtering, and will make sure host/accelerator data is
6134 * loaded for CPU models that depend on host capabilities
6135 * (e.g. "host"). Done by x86_cpu_expand_features().
6136 *
6137 * 3) CPUID filtering. This initializes extra data related to
6138 * CPUID, and checks if the host supports all capabilities
6139 * required by the CPU. Runnability of a CPU model is
6140 * determined at this step. Done by x86_cpu_filter_features().
6141 *
6142 * Some operations don't require all steps to be performed.
6143 * More precisely:
6144 *
6145 * - CPU instance creation (instance_init) will run only CPU
6146 * model loading. CPU expansion can't run at instance_init-time
6147 * because host/accelerator data may be not available yet.
6148 * - CPU realization will perform both CPU model expansion and CPUID
6149 * filtering, and return an error in case one of them fails.
6150 * - query-cpu-definitions needs to run all 3 steps. It needs
6151 * to run CPUID filtering, as the 'unavailable-features'
6152 * field is set based on the filtering results.
6153 * - The query-cpu-model-expansion QMP command only needs to run
6154 * CPU model loading and CPU expansion. It should not filter
6155 * any CPUID data based on host capabilities.
