DMAECopyMem()

DMAETimeStamp DMAECopyMem	(	void *	dst,
		const void *	src,
		uint32_t	wordCount,
		DMAESwapMode	swap
	)

Starts a DMAE copy operation.

Parameters

dst	Pointer to the destination buffer.
src	Pointer to the source buffer.
wordCount	Number of 32 bit words to copy.
swap	Memory endian swapping mode.

Returns

DMAE operations queue timestamp.

DMAEFillMem()

DMAETimeStamp DMAEFillMem	(	void *	dst,
		uint32_t	val,
		uint32_t	wordCount
	)

Starts a DMAE fill operation.

Parameters

dst	Pointer to the destination buffer.
val	The value to fill the destination buffer.
wordCount	Number of 32 bit words to fill.

Returns

DMAE operations queue timestamp.

DMAEFillMemPhys()

DMAETimeStamp DMAEFillMemPhys	(	void *	dst,
		uint32_t	val,
		uint32_t	wordCount
	)

Starts a DMAE fill operation for a physical address.

Parameters

dst	Pointer to the destination buffer (physical address).
val	The value to fill the destination buffer.
wordCount	Number of 32 bit words to fill.

Returns

DMAE operations queue timestamp.
