Struct Piix4PciBus

pub struct Piix4PciBus { /* private fields */ }

The PCI bus as implemented on the PIIX4 chipset.

Identical to a standard PCI bus, aside from the addition of the RESET_CF9 register, because for some reason, someone thought it’d be a great idea to throw a one-byte register that performs a machine reset right in the middle of the PCI addr register >:(

Implementations

impl Piix4PciBus

pub fn new( register_pio: &mut dyn RegisterPortIoIntercept, reset_evt: Box<dyn Fn() + Send + Sync>, ) -> Self

Create a new Piix4PciBus

pub fn as_pci_bus(&mut self) -> &mut GenericPciBus

bypass the PIIX4 specific stuff, and get a handle to the underlying PCI bus implementation

Trait Implementations

impl ChangeDeviceState for Piix4PciBus

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 Piix4PciBus

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 Piix4PciBus

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

Inspects the object.

impl PortIoIntercept for Piix4PciBus

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 Piix4PciBus

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.
