Param struct for the get default flowId open parameters.
The Param struct for the Rx Flow open function, containing CPSW instance Id for RX flow. The returned channel handle is an opaque variable used to access the RX Flow in other function commands.
bool CpswDma_OpenRxFlowPrms_s::disableCacheOpsFlag |
Flag to disable cache operations on the ring memory
CpswDma_AllocDmaDesccFxn CpswDma_OpenRxFlowPrms_s::dmaDescAllocFxn |
DMA HPD (host packet descriptor) memory allocation callback
CpswDma_FreeDmaDescFxn CpswDma_OpenRxFlowPrms_s::dmaDescFreeFxn |
Transmit HPD (host packet descriptor) memory free callback
uint32_t CpswDma_OpenRxFlowPrms_s::flowIdx |
Flow index to be opened
CpswDma_UdmaFlowPrms CpswDma_OpenRxFlowPrms_s::flowPrms |
UDMA Flow params
void* CpswDma_OpenRxFlowPrms_s::hCbArg |
Argument to be used for the callback routines (it should mean something to layer into which the callback calls)
Udma_DrvHandle CpswDma_OpenRxFlowPrms_s::hUdmaDrv |
UDMA driver handle
CpswDma_PktNotifyCb CpswDma_OpenRxFlowPrms_s::notifyCb |
CPSW DMA event callback function - this function will be called when the registered packets are received on RX Flow
uint32_t CpswDma_OpenRxFlowPrms_s::numRxPkts |
Number of receive packets, used for allocating number of DMA descriptors Note - The HW ring element count field is 19-bit
CpswDma_AllocRingMemFxn CpswDma_OpenRxFlowPrms_s::ringMemAllocFxn |
Callback functions. Callback function typedefs so that the CpswDma layer can call into the app layer and let it translate between the hardware buffer descriptors and packets and the stack/translation layer's buffers and packets
Ring memory allocation callback, this cannot be NULL
CpswDma_FreeRingMemFxn CpswDma_OpenRxFlowPrms_s::ringMemFreeFxn |
Ring memory free function callback, used in close flow
uint32_t CpswDma_OpenRxFlowPrms_s::rxFlowMtu |
Maximum receive packet length for this flow. Make sure packets of at least this length are submitted in CpswDma_submitRxPackets()
uint32_t CpswDma_OpenRxFlowPrms_s::startIdx |
Flow start index
CpswDma_UdmaChPrms CpswDma_OpenRxFlowPrms_s::udmaChPrms |
UDMA specific channel params
bool CpswDma_OpenRxFlowPrms_s::useProxy |
Flag to indicate if a dedicated proxy should be allocated for the "FQ" for this flow. This should be enabled only for those flows that require very high throughput as there are limited proxy available in the system
