Subject: [PATCH] dmaengine: fsl-dpaa2-qdma: Add the DPDMAI(Data Path DMA
|
||
|
Interface) support
|
||
|
|
||
|
The MC(Management Complex) exports the DPDMAI(Data Path DMA Interface)
|
||
|
object as an interface to operate the DPAA2(Data Path Acceleration
|
||
|
Architecture 2) qDMA Engine. The DPDMAI enables sending frame-based
|
||
|
requests to qDMA and receiving back confirmation response on transaction
|
||
|
completion, utilizing the DPAA2 QBMan(Queue Manager and Buffer Manager
|
||
|
hardware) infrastructure. DPDMAI object provides up to two priorities for
|
||
|
processing qDMA requests.
|
||
|
The following list summarizes the DPDMAI main features and capabilities:
|
||
|
1. Supports up to two scheduling priorities for processing
|
||
|
service requests.
|
||
|
- Each DPDMAI transmit queue is mapped to one of two service
|
||
|
priorities, allowing further prioritization in hardware between
|
||
|
requests from different DPDMAI objects.
|
||
|
2. Supports up to two receive queues for incoming transaction
|
||
|
completion confirmations.
|
||
|
- Each DPDMAI receive queue is mapped to one of two receive
|
||
|
priorities, allowing further prioritization between other
|
||
|
interfaces when associating the DPDMAI receive queues to DPIO
|
||
|
or DPCON(Data Path Concentrator) objects.
|
||
|
3. Supports different scheduling options for processing received
|
||
|
packets:
|
||
|
- Queues can be configured either in 'parked' mode (default),
|
||
|
or attached to a DPIO object, or attached to DPCON object.
|
||
|
4. Allows interaction with one or more DPIO objects for
|
||
|
dequeueing/enqueueing frame descriptors(FD) and for
|
||
|
acquiring/releasing buffers.
|
||
|
5. Supports enable, disable, and reset operations.
|
||
|
|
||
|
Add dpdmai to support some platforms with dpaa2 qdma engine.
