[LX2160A] Linux support for Scatter Gather M2M DMA

[jhkim2]

Hi,

I wish to use M2M DMA with scatter gather operation.

I want to DMA from source with serveral memory segments to 1 memory segment destation memory.

I searched for the routines for M2M dma with scatter gather option in linux, but not found.

Is the lsdk linux routine for DPAA2 DMA not supporting the scatter gather DMA operation?

Please give the information.

Thanks in advance

Linux kernel QDMA driver doesn't support scatter gather mode, but the QDMA user space driver of DPDK does support scatter gather mode, can it meet your requirement?
