¶async_event enqueue_device_copy(
    device_id device,
    size_t device_lane,
    const void* source_base,
    void* dest_base,
    const region_layout& source_layout,
    const region_layout& dest_layout,
    const region<3>& copy_region,
    size_t elem_size)

Description

Enqueues an n-dimensional copy between two device-accessible allocations (at least one device-native). The operation will complete in-order with respect to any other asynchronous device operation on device and device_lane.

Declared at: include/backend/sycl_backend.h:152

Parameters

device_id device

size_t device_lane

const void* source_base

void* dest_base

const region_layout& source_layout

const region_layout& dest_layout

const region<3>& copy_region

size_t elem_size
