Axi Ethernet and Axi DMA cannot be used together?

    According to http://www.wiki.xilinx.com/Linux+AXI+Ethernet+driver's description,The Axi Ethernet driver contains the AXI DMA code as well so need to disable the AXI DMA Linux driver in the Kernel Menu config.But we have a lot of custom data that needs to be passed from PS to PL via AXI DMA,And we need to extend two AXI Ethernet ports on the PL side,Could you tell me how to resolve this conflict?

    Thanks!

Re: Axi Ethernet and Axi DMA cannot be used together?

Hi @jiandanqinxin, this is not really possible. You will have to write your own driver. This is a known GAP.  There is a plan to update the AXI Ethernet driver w/o AXI DMA; but it won't be there before 2018.1 (current road map but may need to re-check).
