Implementations

impl PcieDownstreamPort

pub fn new(primary_bus_num: u8, secondary_bus_num: u8, hotplugged: bool) -> Self

Constructs a new PCIE downstream port

pub fn new_from_host( pcie_host: PcieHostPort, hotplugged: bool ) -> Result<Self, PciDeviceError>

Trait Implementations

impl HotPlugBus for PcieDownstreamPort

fn hot_plug(&mut self, addr: PciAddress) -> Result<Option<Event>>

Request hot plug event. Returns error if the request is not sent. Upon success, optionally returns an event, which is triggerred once when the guest OS completes the request (by sending PCI_EXP_SLTCTL_CCIE). Returns None if no such mechanism is provided.

fn hot_unplug(&mut self, addr: PciAddress) -> Result<Option<Event>>

Request hot unplug event. Returns error if the request is not sent. Upon success, optionally returns an event, which is triggerred once when the guest OS completes the request (by sending PCI_EXP_SLTCTL_CCIE). Returns None if no such mechanism is provided.

fn get_ready_notification(&mut self) -> Result<Event>

Get a notification event when the HotPlugBus is ready for hot plug commands. If the port is already ready, then the notification event is triggerred immediately.

fn get_address(&self) -> Option<PciAddress>

Gets the upstream PCI Address of the hotplug bus

fn get_secondary_bus_number(&self) -> Option<u8>

Gets the secondary bus number of this bus

fn is_match(&self, host_addr: PciAddress) -> Option<u8>

Check whether the hotplug bus is available to add the new device

fn add_hotplug_device( &mut self, hotplug_key: HotPlugKey, guest_addr: PciAddress )

Add hotplug device into this bus

fn get_hotplug_device(&self, hotplug_key: HotPlugKey) -> Option<PciAddress>

get guest pci address from the specified hotplug_key

fn is_empty(&self) -> bool

Check whether this hotplug bus is empty

fn get_hotplug_key(&self) -> Option<HotPlugKey>

Get hotplug key of this hotplug bus
