Member Data Documentation

__pad0__

uint32_t cpuid_0x04h_edx_fields::__pad0__

cache_inclusiveness

uint8_t cpuid_0x04h_edx_fields::cache_inclusiveness

Cache Inclusiveness.

0 = Cache is not inclusive of lower cache levels.
1 = Cache is inclusive of lower cache levels.

copmlex_cache_indexing

uint8_t cpuid_0x04h_edx_fields::copmlex_cache_indexing

Complex Cache Indexing.

0 = Direct mapped cache.
1 = A complex function is used to index the cache, potentially using all address bits.

write_back

uint8_t cpuid_0x04h_edx_fields::write_back

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.
