Trait Implementations

impl ChangeDeviceState for HostPciBridge

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 HostPciBridge

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

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

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

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

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

Optionally returns a trait object to send MMIO 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_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 HostPciBridge

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

Inspects the object.

impl PciConfigSpace for HostPciBridge

fn pci_cfg_read(&mut self, offset: u16, value: &mut u32) -> IoResult

Dispatch a PCI config space read to the device with the given address.

fn pci_cfg_write(&mut self, offset: u16, value: u32) -> IoResult

Dispatch a PCI config space write to the device with the given address.

fn suggested_bdf(&mut self) -> Option<(u8, u8, u8)>

Check if the device has a suggested (bus, device, function) it expects to be located at.

impl SaveRestore for HostPciBridge

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.
