Enum cortex_a::registers::CPACR_EL1::ZEN::Value

#[repr(u64)]
pub enum Value {
    TrapEl0El1,
    TrapEl0,
    TrapEl1El0,
    TrapNothing,
}

When FEAT_SVE is implemented:

Traps execution at EL1 and EL0 of SVE instructions and instructions that directly access the ZCR_EL1 Systme register to EL1, or to EL2 when El2 is implemented in the current Security state and HCR_EL2.TGE is 1.

The exception is reported using ESR_ELx.EC value 0x19.

A trap taken as a result of CPACR_EL1.ZEN has precedence over a trap taken as a result of CPACR_EL1.FPEN.

On a Warm reset, this field resets to an undefined value.

Otherwise:

Reserved.

Variants

TrapEl0El1

This control causes execution of these instructions at EL0 and EL1 to be trapped.

TrapEl0

This control causes execution of these instructions at EL0 to be trapped, but does not cause execution of any instructions at EL1 to be trapped.

TrapEl1El0

This control causes execution of these instructions at EL1 and EL0 to be trapped.

TrapNothing

This control does not cause execution of any instructions to be trapped.

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
