PCIe simulation.

Dear Team ,

We are working on the Altera Cyclone 4 GX-Starter kit [ PCIe IP as an endpoint ].

1) Could you please provide the required document / memory maap to programm the DMA register ( DMA Descriptor )

( we are planning to build custome driver on Linux 3.11 )

2) We are unable to appriciate "...The chaining DMA uses descriptor tables for each memory page .."

( Page 6 , PCI Express High Performamnce Reference Design )

3) Is there any default linux driver to understand MSI interrupt
