Linux DMA from User Space

Hi,

We are successfully using the dma-proxy DMA driver and dma-proxy-test user application as outlined in :

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842418/Linux+DMA+From+User+Space

Now, to take the design forward, we want to be able to use the AXI Multi-channel DMA controller in the PL. Do the Xilinx DMA drivers (both kernel level and user level) support multi-channel DMA IP core? 

Thanks,

Chintan

Bear in mind the multichannel feature in the AXI DMA is to be discontinued, so you should use the specific AXI Multichannel DMA.

Yes  - I am planning to use the separate AXI Multichannel DMA IP but thanks for pointing that out. The question remains - do the linux drivers (dma-proxy, axidma) and user-space applications (dma-proxy-test) provided by Xilinx work with the AXI Multichannel DMA IP.
