4914 | * | |
4915 | * When initializing and realizing a CPU object, the steps | |
4916 | * involved in setting up CPUID data are: | |
4917 | * | |
4918 | * 1) Loading CPU model definition (X86CPUDefinition). This is | |
4919 | * implemented by x86_cpu_load_model() and should be completely | |
4920 | * transparent, as it is done automatically by instance_init. | |
4921 | * No code should need to look at X86CPUDefinition structs | |
4922 | * outside instance_init. | |
4923 | * | |
4924 | * 2) CPU expansion. This is done by realize before CPUID | |
4925 | * filtering, and will make sure host/accelerator data is | |
4926 | * loaded for CPU models that depend on host capabilities | |
4927 | * (e.g. "host"). Done by x86_cpu_expand_features(). | |
4928 | * | |
4929 | * 3) CPUID filtering. This initializes extra data related to | |
4930 | * CPUID, and checks if the host supports all capabilities | |
4931 | * required by the CPU. Runnability of a CPU model is | |
4932 | * determined at this step. Done by x86_cpu_filter_features(). | |
4933 | * | |
4934 | * Some operations don't require all steps to be performed. | |
4935 | * More precisely: | |
4936 | * | |
4937 | * - CPU instance creation (instance_init) will run only CPU | |
4938 | * model loading. CPU expansion can't run at instance_init-time | |
4939 | * because host/accelerator data may be not available yet. | |
4940 | * - CPU realization will perform both CPU model expansion and CPUID | |
4941 | * filtering, and return an error in case one of them fails. | |
4942 | * - query-cpu-definitions needs to run all 3 steps. It needs | |
4943 | * to run CPUID filtering, as the 'unavailable-features' | |
4944 | * field is set based on the filtering results. | |
4945 | * - The query-cpu-model-expansion QMP command only needs to run | |
4946 | * CPU model loading and CPU expansion. It should not filter | |
4947 | * any CPUID data based on host capabilities. | |
