kx705 pcie trd linux driver

Hi, I'm working with kc705 trd project. I'm working now in UBUNTU 14.  I'm using pci_x8_gen1.mcs and i see device "Memory Controller :  Xilinx corporation Device 7081" after command "lspci". I changed PCI_DEVICE_ID_DMA to 0x7081 in xdma_base.c file. I make linux driver, but in list (after command 'lsmod') i see only "xdma_k7  0"   . XRAWDATA0 and XRAWDATA1 is not make and not working. I want to understand how to read/write the data from/to kc705 board throw PCIe.

 

 

I see post http://forums.xilinx.com/t5/Xilinx-Boards-and-Kits/PCI-e-link-down-in-Kintex7-kc705-embedded-kit-How-to-reconfigure/td-p/344627 

 

Please help.
