How to map DDR on PCI address space?

Hi,

I'm new to PCI, I've following scenario where I need to map DDR memory into PCI address space,

In Custom board,

FPGA is connected via PCIe.
DMAC will be loaded on the PCIe to offload memory transfer between DDR to PCIe.

Question is how mapping of DDR on PCI address space happening ?

Could you please refer if any API available to do that?

Thanks,

Vishnu

Dear Igor,

Thanks for sharing link. This link has information about RC validation and doesn't have any information about mapping DDR memory into PCI address space.

Thanks,

Vishnu
