Implementations

impl CacheParameter

pub fn cache_type(&self) -> CacheType

Cache Type

pub fn level(&self) -> u8

Cache Level (starts at 1)

pub fn is_self_initializing(&self) -> bool

Self Initializing cache level (does not need SW initialization).

pub fn is_fully_associative(&self) -> bool

Fully Associative cache

pub fn max_cores_for_cache(&self) -> usize

Maximum number of addressable IDs for logical processors sharing this cache

pub fn max_cores_for_package(&self) -> usize

Maximum number of addressable IDs for processor cores in the physical package

pub fn coherency_line_size(&self) -> usize

System Coherency Line Size (Bits 11-00)

pub fn physical_line_partitions(&self) -> usize

Physical Line partitions (Bits 21-12)

pub fn associativity(&self) -> usize

Ways of associativity (Bits 31-22)

pub fn sets(&self) -> usize

Number of Sets (Bits 31-00)

pub fn is_write_back_invalidate(&self) -> bool

Write-Back Invalidate/Invalidate (Bit 0) False: WBINVD/INVD from threads sharing this cache acts upon lower level caches for threads sharing this cache. True: WBINVD/INVD is not guaranteed to act upon lower level caches of non-originating threads sharing this cache.

pub fn is_inclusive(&self) -> bool

Cache Inclusiveness (Bit 1) False: Cache is not inclusive of lower cache levels. True: Cache is inclusive of lower cache levels.

pub fn has_complex_indexing(&self) -> bool

Complex Cache Indexing (Bit 2) False: Direct mapped cache. True: A complex function is used to index the cache, potentially using all address bits.

Trait Implementations

impl Clone for CacheParameter

fn clone(&self) -> CacheParameter

Returns a copy of the value.
