Data Structures
struct	tivx_display_crop_params_t
	The configuration data structure for setting crop parameters. More...

struct	tivx_display_params_t
	The configuration data structure used by the TIVX_KERNEL_DISPLAY kernel. More...

struct	tivx_display_select_channel_params_t
	Channels parameters for selecting channel to be displayed. Passed as an argument to TIVX_DISPLAY_SELECT_CHANNEL control command. More...

Macros
#define	TIVX_KERNEL_DISPLAY_NAME "com.ti.display"
	Display Kernel Name.

#define	TIVX_DISPLAY_SELECT_CHANNEL (0x30000000u)
	Control Command to select the channel to be displayed. More...

#define	TIVX_DISPLAY_SET_CROP_PARAMS (0x30000001u)
	Control Command to set the Crop parameters. More...

Display Kernel 's Operation Mode
Display kernel can be run in two modes: it can be used to display only one buffer repeatedly or application provides a new buffer every VSYNC. In case of one buffer, kernel needs to maintain a local copy of the buffer.
#define	TIVX_KERNEL_DISPLAY_ZERO_BUFFER_COPY_MODE ((uint32_t) 0U)
	Display Kernel does not need to maintain buffer copy i.e. application gives new frame at every VSYNC.

#define	TIVX_KERNEL_DISPLAY_BUFFER_COPY_MODE ((uint32_t) 1U)
	Display Kernel needs to maintain buffer copy.

Functions
void	tivxRegisterVideoIOTargetDisplayKernels (void)
	Function to register Video IO Kernels on the display Target.

void	tivxUnRegisterVideoIOTargetDisplayKernels (void)
	Function to un-register Video IO Kernels on the display Target.

VX_API_ENTRY vx_node VX_API_CALL	tivxDisplayNode (vx_graph graph, vx_user_data_object configuration, vx_image image)
	[Graph] Creates a DSS Display Node. More...
