_DMA_DATA Struct Reference

#include <platform.h>

Data Fields
void *	source
	Source address for DMA (May need to be allocated in accordance with DMA host configuration).
void *	dest
	Dest address for DMA (May need to be allocated in accordance with DMA host configuration).
uint32_t	size
	Size for DMA transfer (For 2D stride the length of a row multiplied by the count of rows).
uint32_t	flags
	Flags for DMA transfer (See DMA_DATA_FLAG_* above).
uint32_t	stridelength
	Length of each row during 2D stride (If supported).
int32_t	sourcestride
	Increment between rows for source address during 2D stride (If supported).
int32_t	deststride
	Increment between rows for destination address during 2D stride (If supported).
DMA_DATA *	next
	Link to next DMA data block (or nil for the last block).
