Struct MappedIrqLine

pub struct MappedIrqLine {
    irq_line: IrqLine,
    gsi_index: u32,
    irq_chip: &'static IrqChip,
}

An IrqLine mapped to an IRQ pin managed by an IrqChip.

When the object is dropped, the IRQ line will be unmapped by the IRQ chip.

Fields

irq_line: IrqLine

gsi_index: u32

irq_chip: &'static IrqChip

Methods from Deref<Target = IrqLine>

pub fn num(&self) -> u8

Gets the IRQ number.

pub fn on_active<F>(&mut self, callback: F)

where F: Fn(&TrapFrame) + Sync + Send + 'static,

Registers a callback that will be invoked when the IRQ is active.

For each IRQ line, multiple callbacks may be registered.

pub fn is_empty(&self) -> bool

Checks if there are no registered callbacks.

pub fn remapping_index(&self) -> Option<u16>

Gets the remapping index of the IRQ line.

This method will return None if interrupt remapping is disabled or not supported by the architecture.
