P2040: PCIe testing between two processors

Hi All,

My board is having 2 P2040 chipset. And both are connected via PCIe lines. 
I want to perform some data transfer between processors over PCIe interface.

Have very limited knowledge about PCIe. Till now i understood that one processor has to be in Root complex mode and another one has to be end point.
My doubts are,

1) How to configure processors for RC/Endpoints. What all configurations i need to see (RCW/kernel/device driver side)

2) Is there any application code for user space??

 

Thanks in advance !!
