> The enum rte_dma_direction must have a member RTE_DMA_DIR_ANY for a channel that supports all 4 directions.

We've discussed this issue before. The earliest solution was to set up channels to support multiple DIRs, but
no hardware/driver actually used this (at least at that time). they (like octeontx2_dma/dpaa) all setup one logic
channel server single transfer direction.

So, do you have that kind of desire for your driver ?


If you have a strong desire, we'll consider the following options:

Once the channel was setup, there are no other parameters to indicate the copy request's transfer direction.
So I think it is not enough to define RTE_DMA_DIR_ANY only.

Maybe we could add RTE_DMA_OP_xxx marco (RTE_DMA_OP_FLAG_M2M/M2D/D2M/D2D), these macro will as the flags parameter
passsed to enqueue API, so the enqueue API knows which transfer direction the request corresponding.

We can easily expand from the existing framework with following:
a. define capability RTE_DMADEV_CAPA_DIR_ANY, for those device which support it could declare it.
b. define direction macro: RTE_DMA_DIR_ANY
c. define dma_op: RTE_DMA_OP_FLAG_DIR_M2M/M2D/D2M/D2D which will passed as the flags parameters.

For that driver which don't support this feature, just don't declare support it, and framework ensure that
RTE_DMA_DIR_ANY is not passed down, and it can ignored RTE_DMA_OP_FLAG_DIR_xxx flag when enqueue API.

For that driver which support this feature, application could create one channel with RTE_DMA_DIR_ANY or RTE_DMA_DIR_MEM_TO_MEM.
If created with RTE_DMA_DIR_ANY, the RTE_DMA_OP_FLAG_DIR_xxx should be sensed in the driver.
If created with RTE_DMA_DIR_MEM_TO_MEM, the RTE_DMA_OP_FLAG_DIR_xxx could be ignored.
