Introduction

UDMA utility API to make TR, get TR descriptor memory requirement.

Macros
#define	UDMA_GET_TRPD_TR15_SIZE(n) (UDMA_ALIGN_SIZE(sizeof(CSL_UdmapTR15) + ((n) * (sizeof(CSL_UdmapTR15) + 4U))))
	UDMA TR15 packet descriptor memory size in bytes. This contains the CSL_UdmapCppi5TRPD + Padding to sizeof(CSL_UdmapTR15) + N* Type_15 TR (CSL_UdmapTR15) + N* TR response of 4 bytes. Since CSL_UdmapCppi5TRPD header is less than CSL_UdmapTR15, CSL_UdmapTR15 itself is used for size alignment. More...

Functions
uint32_t	UdmaUtils_getRingMemSize (uint8_t mode, uint32_t elemCnt, uint8_t elemSize)
	UDMA get ring size utility API. More...

void	UdmaUtils_makeTrpdTr15 (uint8_t *trpdMem, uint32_t trCnt, uint32_t cqRingNum)

	UDMA utility API to make TRPD. Other TRPD make APIs should be called only after this API. More...

uint32_t	UdmaUtils_getTrSizeEncoded (uint32_t trType)
	Returns the size of TR (encoded) based on the type. More...

uint32_t	UdmaUtils_getTrSizeBytes (uint32_t trType)
