halide_buffer_t

struct halide_buffer_t

The raw representation of an image passed around by generated Halide code.

It includes some stuff to track whether the image is not actually in main memory, but instead on a device (like a GPU). For a more convenient C++ wrapper, use Halide::Buffer<T>.

Public Members

uint64_t device

A device-handle for e.g.

GPU memory used to back this buffer.

const struct halide_device_interface_t *device_interface

The interface used to interpret the above handle.

uint8_t *host

A pointer to the start of the data in main memory.

In terms of the Halide coordinate system, this is the address of the min coordinates (defined below).

uint64_t flags

flags with various meanings.

struct halide_type_t type

The type of each buffer element.

int32_t dimensions

The dimensionality of the buffer.

halide_dimension_t *dim

The shape of the buffer.

Halide does not own this array - you must manage the memory for it yourself.

void *padding

Pads the buffer up to a multiple of 8 bytes.
