Extend CPUID support for all feature bits from CPUID. Add a new macro, CPU_FEATURE_USABLE, which can be used to check if a feature is usable at run-time, instead of HAS_CPU_FEATURE and HAS_ARCH_FEATURE. Add COMMON_CPUID_INDEX_D_ECX_1, COMMON_CPUID_INDEX_80000007 and COMMON_CPUID_INDEX_80000008 to check CPU feature bits in them. Tested on i686 and x86-64 as well as using build-many-glibcs.py with x86 targets. * sysdeps/x86/cacheinfo.c (intel_check_word): Updated for cpu_features_basic. (__cache_sysconf): Likewise. (init_cacheinfo): Likewise. * sysdeps/x86/cpu-features.c (get_extended_indeces): Also populate COMMON_CPUID_INDEX_80000007 and COMMON_CPUID_INDEX_80000008. (get_common_indices): Also populate COMMON_CPUID_INDEX_D_ECX_1. Use CPU_FEATURES_CPU_P (cpu_features, XSAVEC) to check if XSAVEC is available. Set the bit_arch_XXX_Usable bits. (init_cpu_features): Use _Static_assert on index_arch_Fast_Unaligned_Load. __get_cpuid_registers and __get_arch_feature. Updated for cpu_features_basic. Set stepping in cpu_features. * sysdeps/x86/cpu-features.h: (FEATURE_INDEX_1): Changed to enum. (FEATURE_INDEX_2): New. (FEATURE_INDEX_MAX): Changed to enum. (COMMON_CPUID_INDEX_D_ECX_1): New. (COMMON_CPUID_INDEX_80000007): Likewise. (COMMON_CPUID_INDEX_80000008): Likewise. (cpuid_registers): Likewise. (cpu_features_basic): Likewise. (CPU_FEATURE_USABLE): Likewise. (bit_arch_XXX_Usable): Likewise. (cpu_features): Use cpuid_registers and cpu_features_basic. (bit_arch_XXX): Reweritten. (bit_cpu_XXX): Likewise. (index_cpu_XXX): Likewise. (reg_XXX): Likewise. * sysdeps/x86/tst-get-cpu-features.c: Include <stdio.h> and <support/check.h>. (CHECK_CPU_FEATURE): New. (CHECK_CPU_FEATURE_USABLE): Likewise. (cpu_kinds): Likewise. (do_test): Print vendor, family, model and stepping. Check HAS_CPU_FEATURE and CPU_FEATURE_USABLE. (TEST_FUNCTION): Removed. Include <support/test-driver.c> instead of "../../test-skeleton.c". * sysdeps/x86_64/multiarch/sched_cpucount.c (__sched_cpucount): Check POPCNT instead of POPCOUNT. * sysdeps/x86_64/multiarch/test-multiarch.c (do_test): Likewise. |
