Struct pci_bus::GenericPciBus

pub struct GenericPciBus { /* private fields */ }

A generic PCI bus.

Implementations

impl GenericPciBus

pub fn new( register_pio: &mut dyn RegisterPortIoIntercept, pio_addr: u16, pio_data: u16, ) -> GenericPciBus

Create a new GenericPciBus with the specified (4-byte) IO ports.

pub fn add_pci_device<D: GenericPciBusDevice>( &mut self, bus: u8, device: u8, function: u8, name: impl AsRef<str>, dev: D, ) -> Result<(), (D, Arc<str>)>

Try to add a PCI device, returning (device, existing_device_name) if the slot is already occupied.

Trait Implementations

impl ChangeDeviceState for GenericPciBus

fn start(&mut self)

Starts a device, allowing it to interact with the guest asynchronously.

async fn stop(&mut self)

Stops a device’s asynchronous work.

async fn reset(&mut self)

Resets the device state to its initial state, for a fresh boot.

impl ChipsetDevice for GenericPciBus

fn supports_pio(&mut self) -> Option<&mut dyn PortIoIntercept>

Optionally returns a trait object to send IO port intercepts to.

fn supports_poll_device(&mut self) -> Option<&mut dyn PollDevice>

Optionally returns a trait object to send poll requests to.

fn supports_mmio(&mut self) -> Option<&mut (dyn MmioIntercept + 'static)>

Optionally returns a trait object to send MMIO port intercepts to.

fn supports_pci(&mut self) -> Option<&mut (dyn PciConfigSpace + 'static)>

Optionally returns a trait object to send PCI config space accesses to.

fn supports_line_interrupt_target( &mut self, ) -> Option<&mut dyn LineInterruptTarget>

Optionally returns a trait object to send interrupt line changes to.

fn supports_handle_eoi(&mut self) -> Option<&mut dyn HandleEoi>

Optionally returns a trait object to send EOI requests to.

fn supports_acknowledge_pic_interrupt( &mut self, ) -> Option<&mut dyn AcknowledgePicInterrupt>

Optionally returns a trait object with which to acknowledge PIC interrupts.

impl InspectMut for GenericPciBus

fn inspect_mut(&mut self, req: Request<'_>)

Inspects the object.

impl PollDevice for GenericPciBus

fn poll_device(&mut self, cx: &mut Context<'_>)

Poll the device for asynchronous work.

impl PortIoIntercept for GenericPciBus

fn io_read(&mut self, io_port: u16, data: &mut [u8]) -> IoResult

Dispatch an IO port read to the device with the given address.

fn io_write(&mut self, io_port: u16, data: &[u8]) -> IoResult

Dispatch an IO port write to the device with the given address.

fn get_static_regions(&mut self) -> &[(&str, RangeInclusive<u16>)]

Report a set of static io port regions (region_name, port_range) that cannot be remapped at runtime and are always registered.

impl SaveRestore for GenericPciBus

type SavedState = SavedState

The concrete saved state type.

fn save(&mut self) -> Result<Self::SavedState, SaveError>

Saves the object’s state.

fn restore(&mut self, state: Self::SavedState) -> Result<(), RestoreError>

Restores the object’s state.
