Struct Mpidr

pub struct Mpidr {
    pub aff0: u8,
    pub aff1: u8,
    pub aff2: u8,
    pub aff3: Option<u8>,
}

The type contains the affinity fields of the MPIDR register. For AArch32 callers this contains Affinity 0, 1, 2 fields and for AAarch64 callers it has Affinity 0, 1, 2, 3 fields.

Fields

aff0: u8

aff1: u8

aff2: u8

aff3: Option<u8>

Implementations

impl Mpidr

pub const fn from_aff3210(aff3: u8, aff2: u8, aff1: u8, aff0: u8) -> Self

Create Mpidr instance from aff3-0 values

pub const fn from_aff210(aff2: u8, aff1: u8, aff0: u8) -> Self

Create Mpidr instance from aff2-0 values

pub fn from_register_value(mpidr_el1: u64) -> Self

The MPIDR_EL1 register contains bits other then the aff3-0 fields. However the PSCI specification request bits[40:63] and bits[24:31] to be set to zero when forwarding an MPIDR value as an argument of a PSCI function call. Because of this, the TryFrom implementation returns an error if these bits are set. In other cases the Mpidr value is constructed from the MPIDR_EL1 register value of the local core. This function does this by ignoring other bits. Do not use this function for creating Mpidr instance from a PSCI function argument.

Trait Implementations

impl Clone for Mpidr

fn clone(&self) -> Mpidr

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mpidr

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Mpidr> for u64

fn from(value: Mpidr) -> Self

Converts to this type from the input type.

impl PartialEq for Mpidr

fn eq(&self, other: &Mpidr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Mpidr> for u32

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Mpidr) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u32> for Mpidr

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u64> for Mpidr

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: u64) -> Result<Self, Self::Error>

Performs the conversion.
