Data Structures
struct	Dss_WbPipeCfgParams
	Structure containing video write-back pipe configuration. More...
struct	Dss_WbPipeMflagParams
	Structure containing Video write-back Pipe Mflag Information. This structure is used as an argument to IOCTL_DSS_M2M_SET_WB_PIPE_MFLAG_PARAMS. More...
struct	Dss_WbStatus
	Structure containing current status of the display M2M driver. This structure is used as an argument to IOCTL_DSS_M2M_GET_CURRENT_STATUS. More...
struct	Dss_WbCreateParams
	Structure containing display driver create arguments, used when calling Fvid2_create(). Application shall maintain same create time configurations between multiple driver handles for same WB pipe-line. More...
struct	Dss_WbCreateStatus
	DSS M2M driver create status. Returned after calling Fvid2_create(). More...
struct	Dss_PipeCfgParams
	Structure containing video pipe configuration. This structure is used as an argument to IOCTL_DSS_M2M_SET_PIPE_PARAMS. More...
struct	Dss_PipeMflagParams
	Structure containing Video Pipe Mflag Information. This structure is used as an argument to IOCTL_DSS_M2M_SET_PIPE_MFLAG_PARAMS. More...
struct	Dss_PipeCscParams
	Structure containing Video Pipe CSC Information. This structure is used as an argument to IOCTL_DSS_M2M_SET_PIPE_CSC_COEFF. More...

Macros
