Trait SynicMonitorAccess 

pub trait SynicMonitorAccess: SynicPortAccess {
    // Required method
    fn set_monitor_page(
        &self,
        vtl: Vtl,
        gpa: Option<MonitorPageGpas>,
    ) -> Result<()>;

    // Provided method
    fn allocate_monitor_page(&self, vtl: Vtl) -> Result<Option<MonitorPageGpas>> { ... }
}

Provides monitor page functionality for a SynicPortAccess implementation.

Required Methods

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

Sets the GPA of the monitor page currently in use.

Provided Methods

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).

The pages will be deallocated if the monitor page is subsequently changed or cleared using SynicMonitorAccess::set_monitor_page.

Allocating a host-to-guest monitor page is optional so MonitorPageGpas::parent_to_child may be zero.
