Enum cortex_a::registers::HCR_EL2::RW::Value

#[repr(u64)]
pub enum Value {
    AllLowerELsAreAarch32,
    EL1IsAarch64,
}

Execution state control for lower Exception levels:

0 Lower levels are all AArch32. 1 The Execution state for EL1 is AArch64. The Execution state for EL0 is determined by the current value of PSTATE.nRW when executing at EL0.

If all lower Exception levels cannot use AArch32 then this bit is RAO/WI.

In an implementation that includes EL3, when SCR_EL3.NS==0, the PE behaves as if this bit has the same value as the SCR_EL3.RW bit for all purposes other than a direct read or write access of HCR_EL2.

The RW bit is permitted to be cached in a TLB.

When ARMv8.1-VHE is implemented, and the value of HCR_EL2.{E2H, TGE} is {1, 1}, this field behaves as 1 for all purposes other than a direct read of the value of this bit.

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
