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 VirtioPciDevice

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

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

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_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.
