UDMA utility API to make TRPD. Other TRPD make APIs should be called only after this API.
Note: This sets the most commonly used value for all the fields. User can override the fields after calling this API if required.
- Parameters
-
pTrpd | [IN] Pointer to TRPD memory |
trType | [IN] TR type. Refer Udma_TrType |
trCnt | [IN] Number of TR entries present in the TRPD |
cqRingNum | [IN] Completion ring number where the TRPD is returned after processing |
◆ UdmaUtils_getTrSizeEncoded()
uint32_t UdmaUtils_getTrSizeEncoded |
( |
uint32_t |
trType | ) |
|
Returns the size of TR (encoded) based on the type.
- Parameters
-
- Returns
- Size of the TR record in encoded value to be programmed in TRPD.
◆ UdmaUtils_getTrSizeBytes()
uint32_t UdmaUtils_getTrSizeBytes |
( |
uint32_t |
trType | ) |
|
Returns the size of TR in bytes based on the type.
- Parameters
-
- Returns
- Size of the TR record in bytes.
