Struct ConfigSpace 

pub struct ConfigSpace<'a, S: ConfigSpaceKind = Extended> { /* private fields */ }

The PCI configuration space of a device.

Provides typed read and write accessors for configuration registers using the standard pci_read_config_* and pci_write_config_* helpers.

The generic parameter S indicates the maximum size of the configuration space. Use Normal for 256-byte legacy configuration space or Extended for 4096-byte PCIe extended configuration space (default).

Trait Implementations

impl<'a, S: ConfigSpaceKind> Io for ConfigSpace<'a, S>

fn addr(&self) -> usize

Returns the base address of the I/O region. It is always 0 for configuration space.

fn maxsize(&self) -> usize

Returns the maximum size of the configuration space.

fn read8(&self, offset: usize) -> u8

Read IO data from a given offset known at compile time.

Bound checks are performed on compile time, hence if the offset is not known at compile time, the build will fail.

fn read16(&self, offset: usize) -> u16

Read IO data from a given offset known at compile time.

Bound checks are performed on compile time, hence if the offset is not known at compile time, the build will fail.

fn read32(&self, offset: usize) -> u32

Read IO data from a given offset known at compile time.

Bound checks are performed on compile time, hence if the offset is not known at compile time, the build will fail.

fn write8(&self, value: u8, offset: usize)

Write IO data from a given offset known at compile time.

Bound checks are performed on compile time, hence if the offset is not known at compile time, the build will fail.

fn write16(&self, value: u16, offset: usize)

Write IO data from a given offset known at compile time.

Bound checks are performed on compile time, hence if the offset is not known at compile time, the build will fail.

fn write32(&self, value: u32, offset: usize)

Write IO data from a given offset known at compile time.

Bound checks are performed on compile time, hence if the offset is not known at compile time, the build will fail.

fn io_addr<U>(&self, offset: usize) -> Result<usize>

Returns the absolute I/O address for a given offset, performing runtime bound checks.

fn try_read8(&self, _offset: usize) -> Result<u8>

where Self: IoCapable<u8>,

Fallible 8-bit read with runtime bounds check.

fn try_read16(&self, _offset: usize) -> Result<u16>

where Self: IoCapable<u16>,

Fallible 16-bit read with runtime bounds check.

fn try_read32(&self, _offset: usize) -> Result<u32>

where Self: IoCapable<u32>,

Fallible 32-bit read with runtime bounds check.

fn try_write8(&self, _value: u8, _offset: usize) -> Result

where Self: IoCapable<u8>,

Fallible 8-bit write with runtime bounds check.

fn try_write16(&self, _value: u16, _offset: usize) -> Result

where Self: IoCapable<u16>,

Fallible 16-bit write with runtime bounds check.

fn try_write32(&self, _value: u32, _offset: usize) -> Result

where Self: IoCapable<u32>,

Fallible 32-bit write with runtime bounds check.

impl<'a, S: ConfigSpaceKind> IoKnownSize for ConfigSpace<'a, S>

const MIN_SIZE: usize = S::SIZE

Minimum usable size of this region.

fn io_addr_assert<U>(&self, offset: usize) -> usize

Returns the absolute I/O address for a given offset, performing compile-time bound checks.
