* x86: Support usable check for all CPU featuresH.J. Lu2020-07-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support usable check for all CPU features with the following changes: 1. Change struct cpu_features to struct cpuid_features { struct cpuid_registers cpuid; struct cpuid_registers usable; }; struct cpu_features { struct cpu_features_basic basic; struct cpuid_features features[COMMON_CPUID_INDEX_MAX]; unsigned int preferred[PREFERRED_FEATURE_INDEX_MAX]; ... }; so that there is a usable bit for each cpuid bit. 2. After the cpuid bits have been initialized, copy the known bits to the usable bits. EAX/EBX from INDEX_1 and EAX from INDEX_7 aren't used for CPU feature detection. 3. Clear the usable bits which require OS support. 4. If the feature is supported by OS, copy its cpuid bit to its usable bit. 5. Replace HAS_CPU_FEATURE and CPU_FEATURES_CPU_P with CPU_FEATURE_USABLE and CPU_FEATURE_USABLE_P to check if a feature is usable. 6. Add DEPR_FPU_CS_DS for INDEX_7_EBX_13. 7. Unset MPX feature since it has been deprecated. The results are 1. If the feature is known and doesn't requre OS support, its usable bit is copied from the cpuid bit. 2. Otherwise, its usable bit is copied from the cpuid bit only if the feature is known to supported by OS. 3. CPU_FEATURE_USABLE/CPU_FEATURE_USABLE_P are used to check if the feature can be used. 4. HAS_CPU_FEATURE/CPU_FEATURE_CPU_P are used to check if CPU supports the feature.
