Implementations

impl CqEq<Cqe>

pub fn new_cq(mem: MemoryBlock, doorbell: DoorbellPage, id: u32) -> Self

Creates a new completion queue.

pub fn restore_cq( mem: MemoryBlock, state: CqEqSavedState, doorbell: DoorbellPage, ) -> Self

Restores an existing completion queue.

impl CqEq<Eqe>

pub fn new_eq(mem: MemoryBlock, doorbell: DoorbellPage, id: u32) -> Self

Creates a new event queue.

pub fn restore_eq( mem: MemoryBlock, state: CqEqSavedState, doorbell: DoorbellPage, ) -> Self

Restores an existing event queue.

impl<T: IntoBytes + FromBytes + Immutable + KnownLayout> CqEq<T>

pub fn save(&self) -> CqEqSavedState

Save the state of the queue for restoration after servicing.

pub fn restore( queue_type: GdmaQueueType, mem: MemoryBlock, doorbell: DoorbellPage, state: CqEqSavedState, ) -> Self

Restore a queue from saved state.

pub fn id(&self) -> u32

Gets the queue ID.

pub fn pop(&mut self) -> Option<T>

Pops an event queue entry.

pub fn arm(&mut self)
