Detailed Description

State structure shared between SDMAK and SDMA user layers.

Remarks:

The address of a struct SDMA_transferState instance gets passed down to the SDMAK module during the SDMA_IOCREQUESTDMA ioctl() operation and is registered with the received channel. It is therefore vital that the structure address that is registered with the kernel module points to the actual location that is queried and written during a "wait" operation.
