## Functions
const struct halide_device_interface_t * | halide_hexagon_dma_device_interface ()
int | halide_hexagon_dma_device_wrap_native (void *user_context, struct halide_buffer_t *buf, uint64_t mem)
| This API is used to set up the DMA device interface to be used for DMA transfer.
int | halide_hexagon_dma_device_detach_native (void *user_context, struct halide_buffer_t *buf)
| Detach the Input/Output Buffer from DMA device handle and deallocate the DMA device handle buffer allocation This API also frees up the DMA device and makes it available for another usage.
int | halide_hexagon_dma_allocate_engine (void *user_context, void **dma_engine)
| This API will allocate a DMA Engine needed for DMA read/write.
int | halide_hexagon_dma_deallocate_engine (void *user_context, void *dma_engine)
| This API free up the allocated DMA engine.
int | halide_hexagon_dma_prepare_for_copy_to_host (void *user_context, struct halide_buffer_t *buf, void *dma_engine, bool is_ubwc, halide_hexagon_image_fmt_t fmt)
| This API Prepares a buffer for DMA Read Operation.
int | halide_hexagon_dma_prepare_for_copy_to_device (void *user_context, struct halide_buffer_t *buf, void *dma_engine, bool is_ubwc, halide_hexagon_image_fmt_t fmt)
| This API Prepares a buffer for DMA Write Operation.
int | halide_hexagon_dma_unprepare (void *user_context, struct halide_buffer_t *buf)
| This API is used to frees up the DMA Resources associated with the buffer.
int | halide_hexagon_dma_power_mode_voting (void *user_context, halide_hexagon_power_mode_t cornercase)
| This API is used to setup the hexagon Operation modes.
