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

pub const MANAGED_INTERRUPT_PRIORITY_RANGE: Range<InterruptPriority>

The range of interrupt priority values considered managed.

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

Provided methods

pub unsafe fn init()

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

pub 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.

pub 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.

pub 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.

pub 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.

pub 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.

pub 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.
