Enum cortex_a::registers::SCTLR_EL1::DZE::Value

#[repr(u64)]
pub enum Value {
    Trap,
    DontTrap,
}

Traps EL0 execution of DC ZVA instructions to EL1, from AArch64 state only.

0 Any attempt to execute a DC ZVA instruction at EL0 using AArch64 is trapped to EL1. Reading DCZID_EL0.DZP from EL0 returns 1, indicating that DC ZVA instructions are not supported.

1 This control does not cause any instructions to be trapped.

When ARMv8.1-VHE is implemented, and the value of HCR_EL2.{E2H, TGE} is {1, 1}, this bit has no effect on execution at EL0.

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
