Expand description

An irq chip.

It is a trait for the functions defined in struct irq_chip.

Required Associated Types

The type of the context data stored in the irq chip and made available on each callback.

Required Associated Constants

A marker to prevent implementors from forgetting to use #[vtable] attribute when implementing this trait.

Provided Associated Constants

Indicates if the ack method is overridden by the implementor.

Indicates if the mask method is overridden by the implementor.

Indicates if the unmask method is overridden by the implementor.

Indicates if the set_type method is overridden by the implementor.

Indicates if the set_wake method is overridden by the implementor.

Required Methods

Called at the start of a new interrupt.

Masks an interrupt source.

Unmasks an interrupt source.

Provided Methods

Sets the flow type of an interrupt.

The flow type is a combination of the constants in Type.

Enables or disables power-management wake-on of an interrupt.
