Arria 10 PCIE Linux Driver

Dear，

I'm using Arria 10 FPGA to develop PCIE EP device. I found the PCIE driver on the Linux platform at below link. However, after reading the code, I found that the code could not be used directly for the actual project, and we need took time to modify it. Are there other versions Arria 10 PCIE drivers? If so, please provide the download link address.TKS.
