Function Documentation

void mfc_get_debug	(	volatile void *	ls,
		uint64_t	ea,
		uint32_t	size,
		uint32_t	tag,
		uint32_t	tid,
		uint32_t	rid,
		char *	file,
		int	line
	)

Check parameteris before DMS-transfer.

If code is comlied as DEBUG version, all parameters are checked for formal correctness before the DMA-transfer is initiatied. It is checked weather local storage adress and effective address are equaly aligned and if the transfer size matches the requirements.

Parameters:

	ls	Address in local as for mfc_get.
	ea	Effective address in main memory es for mfc_get.
	size	in bytes as for mfc_get.
	tag	Transfer tag as form mfc_get.
	tid	tid as for mfc_get.
	rid	rid as for mfc_get.
	file	File name of calling sourcefile.
	line	Linenumber in calling sourcefile.

void mfc_put_debug	(	volatile void *	ls,
		uint64_t	ea,
		uint32_t	size,
		uint32_t	tag,
		uint32_t	tid,
		uint32_t	rid,
		char *	file,
		int	line
	)
