packet_buffer: *mut u8

packet_bytes: usize

doorbell: PackedHandle

Implementations

impl SoftGpuQueue

pub fn new( handle: PackedHandle, agent_handle: PackedHandle, id: u64, abi: Box<HsaQueueAbi>, packet_buffer: *mut u8, packet_bytes: usize, doorbell: PackedHandle, ) -> Self

pub fn size_packets(&self) -> u64

pub fn write_index(&self) -> u64

pub fn read_index(&self) -> u64

pub fn observed_through(&self) -> u64

pub fn store_write_index(&self, value: u64)

pub fn store_read_index(&self, value: u64)

pub fn note_doorbell_store(&self)

pub fn doorbell_store_count(&self) -> u64

pub fn abi_ptr(&self) -> *mut HsaQueueAbi

pub fn packet_bytes_at( &self, packet_index: u64, ) -> Result<[u8; 64], PacketValidateError>

pub fn write_packet_type(&self, packet_index: u64, packet_type: u16)

Write a packet header type into the ring (test / SoftGPU producer helper).

pub fn write_packet_bytes(&self, packet_index: u64, bytes: &[u8; 64])

Copy full packet bytes into the ring slot (SoftGPU / test producer).

pub fn invalidate_packet_slot(&self, packet_index: u64)

Mark slot INVALID after SoftGPU consumed it (protocol progress).

pub fn observe_packets( &self, ) -> Result<Vec<PacketObservation>, PacketValidateError>

Observe newly submitted packets exactly once. Copies bytes for Phase 4 parse.

pub fn observed_count(&self) -> usize
