4011 | * | |
4012 | * When initializing and realizing a CPU object, the steps | |
4013 | * involved in setting up CPUID data are: | |
4014 | * | |
4015 | * 1) Loading CPU model definition (X86CPUDefinition). This is | |
4016 | * implemented by x86_cpu_load_def() and should be completely | |
4017 | * transparent, as it is done automatically by instance_init. | |
4018 | * No code should need to look at X86CPUDefinition structs | |
4019 | * outside instance_init. | |
4020 | * | |
4021 | * 2) CPU expansion. This is done by realize before CPUID | |
4022 | * filtering, and will make sure host/accelerator data is | |
4023 | * loaded for CPU models that depend on host capabilities | |
4024 | * (e.g. "host"). Done by x86_cpu_expand_features(). | |
4025 | * | |
4026 | * 3) CPUID filtering. This initializes extra data related to | |
4027 | * CPUID, and checks if the host supports all capabilities | |
4028 | * required by the CPU. Runnability of a CPU model is | |
4029 | * determined at this step. Done by x86_cpu_filter_features(). | |
4030 | * | |
4031 | * Some operations don't require all steps to be performed. | |
4032 | * More precisely: | |
4033 | * | |
4034 | * - CPU instance creation (instance_init) will run only CPU | |
4035 | * model loading. CPU expansion can't run at instance_init-time | |
4036 | * because host/accelerator data may be not available yet. | |
4037 | * - CPU realization will perform both CPU model expansion and CPUID | |
4038 | * filtering, and return an error in case one of them fails. | |
4039 | * - query-cpu-definitions needs to run all 3 steps. It needs | |
4040 | * to run CPUID filtering, as the 'unavailable-features' | |
4041 | * field is set based on the filtering results. | |
4042 | * - The query-cpu-model-expansion QMP command only needs to run | |
4043 | * CPU model loading and CPU expansion. It should not filter | |
4044 | * any CPUID data based on host capabilities. | |
