Struct SynicPorts 

pub struct SynicPorts<T> { /* private fields */ }

Adapts a Synic implementation to [SynicPortAccess].

Wraps a shared SynicPortMap (stored on the partition inner struct) with the Synic trait methods needed for port registration.

Implementations

impl<T: Synic> SynicPorts<T>

pub fn new(synic: Arc<T>) -> Self

Creates a new SynicPorts backed by the given partition.

Trait Implementations

impl<T: Debug> Debug for SynicPorts<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Synic> SynicMonitorAccess for SynicPorts<T>

fn set_monitor_page(&self, vtl: Vtl, gpa: Option<MonitorPageGpas>) -> Result<()>

Sets the GPA of the monitor page currently in use.

fn allocate_monitor_page(&self, vtl: Vtl) -> Result<Option<MonitorPageGpas>>

Allocates monitor pages and sets them as currently in use. If allocating monitor pages is not supported, returns Ok(None).

impl<T: Synic> SynicPortAccess for SynicPorts<T>

fn add_message_port( &self, connection_id: u32, minimum_vtl: Vtl, port: Arc<dyn MessagePort>, ) -> Result<Box<dyn Sync + Send>, Error>

Adds a host message port, which gets notified when the guest calls HvPostMessage.

fn add_event_port( &self, connection_id: u32, minimum_vtl: Vtl, port: Arc<dyn EventPort>, monitor_info: Option<MonitorInfo>, ) -> Result<Box<dyn Sync + Send>, Error>

Adds a host event port, which gets notified when the guest calls HvSignalEvent.

fn new_guest_message_port( &self, vtl: Vtl, vp: u32, sint: u8, ) -> Result<Box<dyn GuestMessagePort>, HypervisorError>

Creates a [GuestMessagePort] for posting messages to the guest.

fn new_guest_event_port( &self, _port_id: u32, vtl: Vtl, vp: u32, sint: u8, flag: u16, _monitor_info: Option<MonitorInfo>, ) -> Result<Box<dyn GuestEventPort>, HypervisorError>

Creates a [GuestEventPort] for signaling VMBus channels in the guest.

fn prefer_os_events(&self) -> bool

Returns whether callers should pass an OS event when creating event ports, as opposed to passing a function to call.

fn monitor_support(&self) -> Option<&dyn SynicMonitorAccess>

Returns an object for manipulating the monitor page, or None if monitor pages aren’t supported.
