Field Documentation

◆ instId

uint32_t Udma_InitPrms::instId

[IN] Udma_InstanceIdSoc

◆ skipGlobalEventReg

uint32_t Udma_InitPrms::skipGlobalEventReg

Skips the global event registeration for the handle. By default this is set to FALSE and application can use this common handle to set the master event to limit the number of IA/IR registration per core This can be set to TRUE to skip this registration as in the case of having multiple handles per core in usecases

◆ virtToPhyFxn

Udma_VirtToPhyFxn Udma_InitPrms::virtToPhyFxn

If not NULL, this function will be called to convert virtual address to physical address to be provided to UDMA. If NULL, the driver will assume a one-one mapping.

◆ phyToVirtFxn

Udma_PhyToVirtFxn Udma_InitPrms::phyToVirtFxn

If not NULL, this function will be called to convert physical address to virtual address to access the pointer returned by the UDMA. If NULL, the driver will assume a one-one mapping.
