UDMA TR type | |
|
Various UDMA TR type supported | |
| #define | UDMA_TR_TYPE_0 (CSL_UDMAP_TR_FLAGS_TYPE_1D_DATA_MOVE) |
| #define | UDMA_TR_TYPE_1 (CSL_UDMAP_TR_FLAGS_TYPE_2D_DATA_MOVE) |
| #define | UDMA_TR_TYPE_2 (CSL_UDMAP_TR_FLAGS_TYPE_3D_DATA_MOVE) |
| #define | UDMA_TR_TYPE_3 (CSL_UDMAP_TR_FLAGS_TYPE_4D_DATA_MOVE) |
| #define | UDMA_TR_TYPE_4 (CSL_UDMAP_TR_FLAGS_TYPE_4D_DATA_MOVE_FORMATTING) |
| #define | UDMA_TR_TYPE_5 (CSL_UDMAP_TR_FLAGS_TYPE_4D_CACHE_WARM) |
| #define | UDMA_TR_TYPE_8 (CSL_UDMAP_TR_FLAGS_TYPE_4D_BLOCK_MOVE) |
| #define | UDMA_TR_TYPE_9 (CSL_UDMAP_TR_FLAGS_TYPE_4D_BLOCK_MOVE_REPACKING) |
| #define | UDMA_TR_TYPE_10 (CSL_UDMAP_TR_FLAGS_TYPE_2D_BLOCK_MOVE) |
| #define | UDMA_TR_TYPE_11 (CSL_UDMAP_TR_FLAGS_TYPE_2D_BLOCK_MOVE_REPACKING) |
| #define | UDMA_TR_TYPE_15 (CSL_UDMAP_TR_FLAGS_TYPE_4D_BLOCK_MOVE_REPACKING_INDIRECTION) |
| #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... | |
| #define | UDMA_TR1_OFFSET (64U) |
| Offset for TR1 type TR from TRPD start address. More... | |
| uint32_t | UdmaUtils_getRingMemSize (uint8_t mode, uint32_t elemCnt, uint8_t elemSize) |
| UDMA get ring size utility API. More... | |
| static void | UdmaUtils_makeTrpd (void *pTrpd, uint32_t trType, 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) |
| Returns the size of TR in bytes based on the type. More... | |
| CSL_UdmapTR1 * | UdmaUtils_getTrpdTr1Pointer (uint8_t *trpdMem, uint32_t trIndex) |
| Returns the TR1 pointer in the TRPD memory based on the index. More... | |
