## 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. More...
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. More...
int | halide_hexagon_dma_allocate_engine (void *user_context, void **dma_engine)
| This API will allocate a DMA Engine needed for DMA read/write. More...
int | halide_hexagon_dma_deallocate_engine (void *user_context, void *dma_engine)
| This API free up the allocated DMA engine. More...
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. More...
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. More...
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. More...
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. More...
