Have you tried changing the Device ID in the drivers code in "altera_dma_cmd.h" from E003 to E001 which is the default value of the Device ID for Altera dev kits. As per the documentation, this value should be E093 for the Arria 10 devices.

E - Gen3 PCIe

0 - Number of lanes (0 -1 lanes)

9 - Arria 10 Device / 7 - Arria V Devices / 0 - Stratix IV GX and so on.

3 - SGDMA mode , Desc/Data (that is, Avalon-Streaming (Avalon-ST) interface)

IF E001 does not work, then try with E093. After modifying the Device ID, you may need to make and install the driver again, ie, ./make , ./install or sudo make / sudo install,etc..
