Provides access to the interrupt line API exposed by a kernel.

Safety

See the Safety section of the module documentation.

Provided Associated Constants

const RAW_MANAGED_INTERRUPT_PRIORITY_RANGE: Range<i16> = #[lang = "Range"]{ start: 0, end: 0,}

The range of interrupt priority values considered managed.

Defaults to 0..0 (empty) when unspecified.

const RAW_MANAGED_INTERRUPT_LINES: &'static [usize] = &[]

The list of interrupt lines which are considered managed.

Defaults to &[] (empty) when unspecified.

This is useful when the driver employs a fixed priority scheme and doesn’t support changing interrupt line priorities.
