This patch introduces 'dmadevice' which is a generic type of DMA
device.

The APIs of dmadev library exposes some generic operations which can
enable configuration and I/O with the DMA devices.

Did you consider RTE_COMP_ALGO_NULL xform in compressdev library?

em, I just looked at the code.

The RTE_COMP_ALGO_NULL is a small feature of the compression device.
and currently only mlx5 and isal support it.

Yes, but what that is mean?
If more drivers support DMA operations they can add the support there, no?

Also the compressdev dataplane API relatively complicated to do just DMA
copy.

You snipped more comments I wrote below 😊
Maybe it is related....

So I think we need a separate driver framework for the DMA device.

Need to consider deprecation in compressdev if so....

thanks
