Hi ,

Are you using the PCIe DMA? If so you can try using https://www.jungo.com/st/products/windriver/wd_linux/

Ya we are using PCIe DMA, but the requirement is to make host dma as master (Linux desktop machine) . When i am trying to call this api

dma_request_channel its failing.

Any ideas where I am going wrong or any example would be quite helpful to me?
