Struct PciDeviceLocation

pub struct PciDeviceLocation {
    pub bus: u8,
    pub device: u8,
    pub function: u8,
}

PCI device Location

Fields

bus: u8

Bus number

device: u8

Device number with max 31

function: u8

Device number with max 7

Implementations

impl PciDeviceLocation

const MIN_BUS: u8 = 0u8

const MAX_BUS: u8 = 255u8

const MIN_DEVICE: u8 = 0u8

const MAX_DEVICE: u8 = 31u8

const MIN_FUNCTION: u8 = 0u8

const MAX_FUNCTION: u8 = 7u8

pub fn all() -> impl Iterator<Item = PciDeviceLocation>

Returns an iterator that enumerates all possible PCI device locations.

pub fn zero() -> Self

The page table of all devices is the same. So we can use any device ID. FIXME: distinguish different device id.

pub(super) fn read32(&self, offset: u16) -> u32

pub(super) fn write8(&self, offset: u16, val: u8)

pub(super) fn write16(&self, offset: u16, val: u16)

Trait Implementations

impl Clone for PciDeviceLocation

fn clone(&self) -> PciDeviceLocation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PciDeviceLocation

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

Formats the value using the given formatter.

impl Ord for PciDeviceLocation

fn cmp(&self, other: &PciDeviceLocation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PciDeviceLocation

fn eq(&self, other: &PciDeviceLocation) -> 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 PartialOrd for PciDeviceLocation

fn partial_cmp(&self, other: &PciDeviceLocation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
