Enum aarch64::regs::SCTLR_EL3::IESB::Value

#[repr(u64)]
pub enum Value {
    Disabled = 0,
    Enabled = 1,
}

When FEAT_IESB is implemented:

Implicit Error Synchronization event enable.

0b0 Disabled.

0b1 An implicit error synchronization event is added:

   • At each exception taken to EL3.

   • Before the operational pseudocode of each ERET instruction executed at EL3.

When the PE is in Debug state, the effect of this field is CONSTRAINED UNPREDICTABLE, and its Effective value might be 0 or 1 regardless of the value of the field and, if implemented, SCR_EL3.NMEA. If the Effective value of the field is 1, then an implicit error synchronization event is added after each DCPSx instruction taken to EL3 and before each DRPS instruction executed at EL3, in addition to the other cases where it is added.

When FEAT_DoubleFault is implemented, the PE is in Non-debug state, and the Effective value of SCR_EL3.NMEA is 1, this field is ignored and its Effective value is 1.

The reset behavior of this field is: • On a Warm reset, in a system where the PE resets into EL3, this field resets to an architecturally UNKNOWN value.

Variants

Disabled = 0

Enabled = 1

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 PartialEq 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<<Value as TryFromValue<u64>>::EnumType>

impl Copy for Value

impl Eq for Value

impl StructuralPartialEq for Value
