Struct kernel::irq::Registration

pub struct Registration<H: Handler>(_);

The registration of an interrupt handler.

Examples

The following is an example of a regular handler with a boxed u32 as data.

use kernel::irq;

struct Example;

impl irq::Handler for Example {
    type Data = Box<u32>;

    fn handle_irq(_data: &u32) -> irq::Return {
        irq::Return::None
    }
}

fn request_irq(irq: u32, data: Box<u32>) -> Result<irq::Registration<Example>> {
    irq::Registration::try_new(irq, data, irq::flags::SHARED, fmt!("example_{irq}"))
}

Implementations

impl<H: Handler> Registration<H>

pub fn try_new(
    irq: u32,
    data: H::Data,
    flags: usize,
    name: Arguments<'_>
) -> Result<Self>

Registers a new irq handler.

The valid values of flags come from the flags module.
