Enum cortex_a::registers::TCR_EL2::PS::Value

#[repr(u64)]
pub enum Value {
    Bits_32,

Physical Address Size.

000 32 bits, 4GiB. 001 36 bits, 64GiB. 010 40 bits, 1TiB. 011 42 bits, 4TiB. 100 44 bits, 16TiB. 101 48 bits, 256TiB. 110 52 bits, 4PB

Other values are reserved.

The reserved values behave in the same way as the 101 or 110 encoding, but software must not rely on this property as the behavior of the reserved values might change in a future revision of the architecture.

The value 110 is permitted only if ARMv8.2-LPA is implemented and the translation granule size is 64KiB.

In an implementation that supports 52-bit PAs, if the value of this field is not 110 , then bits[51:48] of every translation table base address for the stage of translation controlled by TCR_EL2 are 0000.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<Value> for FieldValue<u64, Register>

fn from(v: Value) -> Self

Converts to this type from the input type.

impl PartialEq<Value> for Value

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFromValue<u64> for Value

type EnumType = Value

fn try_from_value(v: u64) -> Option<Self::EnumType>

impl Copy for Value

impl Eq for Value

impl StructuralEq for Value

impl StructuralPartialEq for Value
