Struct Device

pub struct Device(/* private fields */);

The PCI device representation.

A PCI device is based on an always reference counted device:Device instance. Cloning a PCI device, hence, also increments the base device’ reference count.

Invariants

Device hold a valid reference of ARef<device::Device> whose underlying struct device is a member of a struct pci_dev.

Implementations

impl Device

pub unsafe fn from_dev(dev: ARef<Device>) -> Self

Create a PCI Device instance from an existing device::Device.

Safety

dev must be an ARef<device::Device> whose underlying bindings::device is a member of a bindings::pci_dev.

pub fn vendor_id(&self) -> u16

Returns the PCI vendor ID.

pub fn device_id(&self) -> u16

Returns the PCI device ID.

pub fn enable_device_mem(&self) -> Result

Enable memory resources for this device.

pub fn set_master(&self)

Enable bus-mastering for this device.

pub fn resource_len(&self, bar: u32) -> Result<resource_size_t>

Returns the size of the given PCI bar resource.

pub fn iomap_region_sized<const SIZE: usize>( &self, bar: u32, name: &CStr, ) -> Result<Devres<Bar<SIZE>>>

Mapps an entire PCI-BAR after performing a region-request on it. I/O operation bound checks can be performed on compile time for offsets (plus the requested type size) < SIZE.

pub fn iomap_region(&self, bar: u32, name: &CStr) -> Result<Devres<Bar>>

Mapps an entire PCI-BAR after performing a region-request on it.

Trait Implementations

impl AsRef<Device> for Device

fn as_ref(&self) -> &Device

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Device

fn clone(&self) -> Device

Returns a copy of the value.

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

Performs copy-assignment from source.
