Implementations

impl L2And3CacheTlbInfo

pub fn dtlb_2m_4m_associativity(&self) -> Associativity

L2 Data TLB associativity for 2-MB and 4-MB pages.

Availability

✅ AMD ❌ Intel (reserved=0)

pub fn dtlb_2m_4m_size(&self) -> u16

L2 Data TLB number of entries for 2-MB and 4-MB pages.

The value returned is for the number of entries available for the 2-MB page size; 4-MB pages require two 2-MB entries, so the number of entries available for the 4-MB page size is one-half the returned value.

pub fn itlb_2m_4m_associativity(&self) -> Associativity

L2 Instruction TLB associativity for 2-MB and 4-MB pages.

Trait Implementations

impl Debug for L2And3CacheTlbInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for L2And3CacheTlbInfo

fn eq(&self, other: &L2And3CacheTlbInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
