Trait dbs_interrupt::InterruptManager

pub trait InterruptManager {
    fn create_group(
        &self,
        type_: InterruptSourceType,
        base: InterruptIndex,
        count: InterruptIndex
    ) -> Result<Arc<Box<dyn InterruptSourceGroup>>>;
    fn destroy_group(
        &self,
        group: Arc<Box<dyn InterruptSourceGroup>>
    ) -> Result<()>;
}

Trait to manage interrupt sources for virtual device backends.

The InterruptManager implementations should protect itself from concurrent accesses internally, so it could be invoked from multi-threaded context.

Required Methods

fn create_group(
    &self,
    type_: InterruptSourceType,
    base: InterruptIndex,
    count: InterruptIndex
) -> Result<Arc<Box<dyn InterruptSourceGroup>>>

Create an InterruptSourceGroup object to manage interrupt sources for a virtual device.

An InterruptSourceGroup object manages all interrupt sources of the same type for a virtual device.

Arguments

• type_: type of interrupt source.
• base: base Interrupt Source ID to be managed by the group object.
• count: number of Interrupt Sources to be managed by the group object.

fn destroy_group(&self, group: Arc<Box<dyn InterruptSourceGroup>>) -> Result<()>

Destroy an InterruptSourceGroup object created by create_group().

Assume the caller takes the responsibility to disable all interrupt sources of the group before calling destroy_group(). This assumption helps to simplify InterruptSourceGroup implementations.
