Field Documentation

◆ pauseOnError

uint32_t CSL_UdmapRxChanCfg::pauseOnError

[IN] When set, pause channel on error

◆ addrType

CSL_UdmapAddrType CSL_UdmapRxChanCfg::addrType

[IN] Address type for this channel

◆ chanType

CSL_UdmapChanType CSL_UdmapRxChanCfg::chanType

[IN] Channel type

◆ fetchWordSize

uint32_t CSL_UdmapRxChanCfg::fetchWordSize

[IN] Descriptor/TR Size in 32-bit words

◆ trEventNum

uint32_t CSL_UdmapRxChanCfg::trEventNum

[IN] Specifies a global event number to generate anytime the required event generation criteria specified in a TR are met (set to CSL_UDMAP_NO_EVENT for no event generation)

◆ errEventNum

uint32_t CSL_UdmapRxChanCfg::errEventNum

[IN] Specifies a global event number to generate anytime an error is encountered on the channel (set to CSL_UDMAP_NO_EVENT for no event generation)

◆ busPriority

uint32_t CSL_UdmapRxChanCfg::busPriority

[IN] 3-bit priority value (0=highest, 7=lowest)

◆ busQos

uint32_t CSL_UdmapRxChanCfg::busQos

[IN] 3-bit qos value (0=highest, 7=lowest)

◆ busOrderId

uint32_t CSL_UdmapRxChanCfg::busOrderId

[IN] 4-bit orderid value

◆ rxTrCQ

uint32_t CSL_UdmapRxChanCfg::rxTrCQ

[IN] RX TR Completion Queue

◆ rxThread

uint32_t CSL_UdmapRxChanCfg::rxThread

[IN] Rx channel destination ThreadID mapping

◆ flowIdFwRangeStart

uint32_t CSL_UdmapRxChanCfg::flowIdFwRangeStart

[IN] Starting flow ID value for firewall check

◆ flowIdFwRangeCnt

uint32_t CSL_UdmapRxChanCfg::flowIdFwRangeCnt

[IN] Number of valid flow ID's starting from flowIdFwRangeStart for firewall check

◆ bIgnoreShortPkts

bool CSL_UdmapRxChanCfg::bIgnoreShortPkts

[IN] This field controls whether or not short packets will be treated as exceptions (false) or ignored (true) for the channel. This field is only used when the channel is in split UTC mode.

◆ bIgnoreLongPkts

bool CSL_UdmapRxChanCfg::bIgnoreLongPkts

[IN] This field controls whether or not long packets will be treated as exceptions (false) or ignored (true) for the channel. This field is only used when the channel is in split UTC mode.

◆ dmaPriority

CSL_UdmapChanSchedPri CSL_UdmapRxChanCfg::dmaPriority

[IN] This field selects which scheduling bin the channel will be placed in for bandwidth allocation of the Rx DMA units
