Struct pci_driver::config::PciConfig

pub struct PciConfig<'a> { /* private fields */ }

This lets you interact with the config space (conventional or extended) of a PCI device.

This doesn’t have a definite length because we want to preserve the PciSubregion over the whole of config space.

Implementations

impl<'a> PciConfig<'a>

pub fn vendor_id(&self) -> PciRegisterRo<'a, u16>

pub fn device_id(&self) -> PciRegisterRo<'a, u16>

pub fn command(&self) -> PciCommand<'a>

pub fn status(&self) -> PciStatus<'a>

pub fn revision_id(&self) -> PciRegisterRo<'a, u8>

pub fn class_code(&self) -> PciClassCode<'a>

pub fn cache_line_size(&self) -> PciRegisterRw<'a, u8>

pub fn latency_timer(&self) -> PciRegisterRo<'a, u8>

pub fn header_type(&self) -> PciHeaderType<'a>

pub fn bist(&self) -> PciBist<'a>

pub fn cardbus_cis_pointer(&self) -> PciRegisterRo<'a, u32>

pub fn subsystem_vendor_id(&self) -> PciRegisterRo<'a, u16>

pub fn subsystem_id(&self) -> PciRegisterRo<'a, u16>

pub fn interrupt_line(&self) -> PciRegisterRw<'a, u8>

pub fn interrupt_pin(&self) -> PciRegisterRo<'a, u8>

pub fn min_gnt(&self) -> PciRegisterRo<'a, u8>

pub fn max_lat(&self) -> PciRegisterRo<'a, u8>

impl<'a> PciConfig<'a>

pub fn capabilities(&self) -> Result<PciCapabilities<'a>>

Returns a thing that lets you access the PCI Capabilities.

Calling this will (re)scan all Capabilities, which is why it can fail.

pub fn extended_capabilities(&self) -> Result<PciExtendedCapabilities<'a>>

Returns a thing that lets you access the PCI Extended Capabilities.

Calling this will (re)scan all Extended Capabilities, which is why it can fail.

Trait Implementations

impl<'a> AsPciSubregion<'a> for PciConfig<'a>

fn as_subregion(&self) -> PciSubregion<'a>

Returns a PciSubregion corresponding to self.

fn subregion(&self, range: impl RangeBounds<u64>) -> PciSubregion<'a>

Returns a PciSubregion corresponding to a range of self.

impl<'a> BackedByPciSubregion<'a> for PciConfig<'a>

fn backed_by(as_subregion: impl AsPciSubregion<'a>) -> Self

Does not check whether the subregion is big enough. If it isn’t, accesses may later fail.

impl<'a> Clone for PciConfig<'a>

fn clone(&self) -> PciConfig<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PciConfig<'_>

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

Formats the value using the given formatter.
