Enum cortex_a::registers::HCR_EL2::FMO::Value

#[repr(u64)]
pub enum Value {
    DisableVirtualFIQ,
    EnableVirtualFIQ,
}

Physical FIQ Routing. If this bit is 0:

• When executing at Exception levels below EL2, and EL2 is enabled in the current Security state:
  • When the value of HCR_EL2.TGE is 0, Physical FIQ interrupts are not taken to EL2.
  • When the value of HCR_EL2.TGE is 1, Physical FIQ interrupts are taken to EL2 unless they are routed to EL3.
  • Virtual FIQ interrupts are disabled.

If this bit is 1:

• When executing at any Exception level, and EL2 is enabled in the current Security state:
  • Physical FIQ interrupts are taken to EL2, unless they are routed to EL3.
  • When HCR_EL2.TGE is 0, then Virtual FIQ interrupts are enabled.

If EL2 is enabled in the current Security state and the value of HCR_EL2.TGE is 1:

• Regardless of the value of the FMO bit, physical FIQ Interrupts target EL2 unless they are routed to EL3.
• When FEAT_VHE is not implemented, or if HCR_EL2.E2H is 0, this field behaves as 1 for all purposes other than a direct read of the value of this bit.
• When FEAT_VHE is implemented and HCR_EL2.E2H is 1, this field behaves as 0 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
