Struct arm_gic::GicV2

pub struct GicV2 { /* private fields */ }

Driver for an Arm Generic Interrupt Controller version 2.

Implementations

impl GicV2

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

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 GicV2

fn clone(&self) -> GicV2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GicV2

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

Formats the value using the given formatter.

impl GenericArmGic for GicV2

fn init_primary(&mut self)

Initialises the GIC.

fn per_cpu_init(&mut self)

Initialises the GIC for the current CPU core.

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

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

fn enable_interrupt(&mut self, intid: IntId)

Enables the interrupt with the given ID.

fn disable_interrupt(&mut self, intid: IntId)

Disable the interrupt with the given ID.

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 get_and_acknowledge_interrupt(&self) -> Option<IntId>

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