Data Structures | |
| struct | IRES_EDMA3CHAN_PaRamStruct |
| Representation of actual PaRam structure. More... | |
| struct | IRES_EDMA3CHAN_ProtocolArgs |
| EDMA3 Linked Transfer Protocol Arguments definition. When requesting resources on a device on which DCHMAP feature does not exist, please follow these rules:- 1. Break up requests into LOGICAL channel requests and requests for PaRams. 2. Logical Qdma/Edma channel => Q/E channel + PaRam + TCC 3. Avoid requesting EDMA3 resources of specific number, for most transfers an "ANY" type request should be sufficient 4. For linked transfers, request a Logical channel in one descriptor, and "N" contiguous Params in another descriptor 5. If a logical channel request is combined with a request for multiple Params or Tccs, this might result in an in-efficient allocation of resources, and in some cases, simplyfying assumptions about the resource requests may be made by the allocator.
