An abstract interface to an interrupt controller. Implemented by use_plic!.

Safety

These methods are only intended to be called by the port.

Associated Constants

const MANAGED_INTERRUPT_PRIORITY_RANGE: Range<InterruptPriority>

The range of interrupt priority values considered managed.

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

Provided methods

unsafe fn init()

Initialize the driver. This will be called just before entering PortToKernel::boot.

Safety

See this trait’s documentation.

unsafe fn set_interrupt_line_priority(
    _line: InterruptNum,
    _priority: InterruptPriority
) -> Result<(), SetInterruptLinePriorityError>

Handle the call to PortInterrupts::set_interrupt_line_priority for a platform interrupt line.

The provided interrupt number must be greater than or equal to INTERRUPT_PLATFORM_START.

Safety

See this trait’s documentation.

unsafe fn enable_interrupt_line(
    _line: InterruptNum
) -> Result<(), EnableInterruptLineError>

Handle the call to PortInterrupts::enable_interrupt_line for a platform interrupt line.

The provided interrupt number must be greater than or equal to INTERRUPT_PLATFORM_START.

Safety

See this trait’s documentation.

unsafe fn disable_interrupt_line(
    _line: InterruptNum
) -> Result<(), EnableInterruptLineError>

Handle the call to PortInterrupts::disable_interrupt_line for a platform interrupt line.

The provided interrupt number must be greater than or equal to INTERRUPT_PLATFORM_START.

Safety

See this trait’s documentation.

unsafe fn pend_interrupt_line(
    _line: InterruptNum
) -> Result<(), PendInterruptLineError>

Handle the call to PortInterrupts::pend_interrupt_line for a platform interrupt line.

The provided interrupt number must be greater than or equal to INTERRUPT_PLATFORM_START.

Safety

See this trait’s documentation.

unsafe fn clear_interrupt_line(
    _line: InterruptNum
) -> Result<(), ClearInterruptLineError>

Handle the call to PortInterrupts::clear_interrupt_line for a platform interrupt line.

The provided interrupt number must be greater than or equal to INTERRUPT_PLATFORM_START.

Safety

See this trait’s documentation.

unsafe fn is_interrupt_line_pending(
    _line: InterruptNum
) -> Result<bool, QueryInterruptLineError>

Handle the call to PortInterrupts::is_interrupt_line_pending for a platform interrupt line.

The provided interrupt number must be greater than or equal to INTERRUPT_PLATFORM_START.

Safety

See this trait’s documentation.
