Individual bit fields

◆ CacheInclusiveness

UINT32 CPUID_CACHE_PARAMS_EDX::CacheInclusiveness

[Bit 1] Cache Inclusiveness. 0 = Cache is not inclusive of lower cache levels. 1 = Cache is inclusive of lower cache levels.

Definition at line 927 of file Cpuid.h.

◆ ComplexCacheIndexing

UINT32 CPUID_CACHE_PARAMS_EDX::ComplexCacheIndexing

[Bit 2] Complex Cache Indexing. 0 = Direct mapped cache. 1 = A complex function is used to index the cache, potentially using all address bits.

Definition at line 934 of file Cpuid.h.

◆ Invalidate

UINT32 CPUID_CACHE_PARAMS_EDX::Invalidate

[Bit 0] Write-Back Invalidate/Invalidate. 0 = WBINVD/INVD from threads sharing this cache acts upon lower level caches for threads sharing this cache. 1 = WBINVD/INVD is not guaranteed to act upon lower level caches of non-originating threads sharing this cache.
