Struct arm_gic::GicV3

pub struct GicV3 { /* private fields */ }

Driver for an Arm Generic Interrupt Controller version 3 (or 4).

Implementations

impl GicV3

pub const fn new(gicd: *mut u8, gicr: *mut u8) -> Self

Constructs a new instance of the driver for a GIC with the given distributor and redistributor base addresses.

Safety

The given base addresses must point to the GIC distributor and redistributor registers respectively. These regions must be mapped into the address space of the process as device memory, and not have any other aliases, either via another instance of this driver or otherwise.

Trait Implementations

impl Clone for GicV3

fn clone(&self) -> GicV3

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GicV3

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl GenericArmGic for GicV3

fn init_primary(&mut self)

Initialises the GIC.

fn enable_interrupt(&mut self, intid: IntId)

Enables the interrupt with the given ID.

fn set_trigger(&mut self, intid: IntId, tm: TriggerMode)

Configures the trigger type for the interrupt with the given ID.

fn get_and_acknowledge_interrupt(&self) -> Option<IntId>

Gets the ID of the highest priority signalled interrupt, and acknowledges it.

Returns None if there is no pending interrupt of sufficient priority.

fn end_interrupt(&self, intid: IntId)

Informs the interrupt controller that the CPU has completed processing the given interrupt. This drops the interrupt priority and deactivates the interrupt.

fn per_cpu_init(&mut self)

Initialises the GIC for the current CPU core.

fn disable_interrupt(&mut self, intid: IntId)

Disable the interrupt with the given ID.
