| #define | IRES_EDMA3CHAN_PROTOCOLNAME "ti.sdo.fc.ires.edma3chan" |
| Name used to describe this protocol. | |
| #define | EDMA3CHAN_MODNAME "ti.sdo.fc.ires.edma3chan" |
| Name to pass to Diags_setMask() to enable logging for EDMA3CHAN functions. For example, Diags_setMask(EDMA3CHAN_MODNAME"+EX1234567"); turns on all Log statements in this module. Diags_setMask() must be called after initialization to take effect. | |
| #define | EDMA3CHAN_GTNAME "ti.sdo.fc.ires.edma3chan" |
| Name used to describe the GT module. | |
| #define | IRES_EDMA3CHAN_PROTOCOLREVISION_1_0_0 {1, 0, 0} |
| Protocol Revision for the 1.0.0 version of resource. | |
| #define | IRES_EDMA3CHAN_SETPROTOCOLREVISION_1_0_0(rev) |
| #define | IRES_EDMA3CHAN_PROTOCOLREVISION_2_0_0 {2, 0, 0} |
| Protocol Revision for the 2.0.0 version of resource. | |
| #define | IRES_EDMA3CHAN_SETPROTOCOLREVISION_2_0_0(rev) |
| #define | IRES_EDMA3CHAN_MAXPARAMS 512 |
| Maximum number of params and tccs that can be requested in one handle. | |
| #define | IRES_EDMA3CHAN_MAXTCCS 32 |
| #define | IRES_EDMA3CHAN_NUMDESTTYPES 8 |
| #define | IRES_EDMA3CHAN_PARAM_ANY 512 |
| Macros to represent different PaRam, Channel and tcc types. | |

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.

| struct | IRES_EDMA3CHAN_Obj |
| IRES_EDMA3CHAN_Obj extends the generic IRES_Obj structure that is returned back to the algorithm requesting the resource. More... | |
| struct | IRES_EDMA3CHAN_EDMA3ShadowRegister |
