How to configure and use PCIe Gen2 interface in Xeon D

PCIe Gen2 interface (x8) is listed in the product brief of Intel® Xeon® Processor D-1500
Product Family document. Couldn't find the configuration registers for PCIe Gen2 interface in the datasheet. Also checked the BSF file(Firmware support package) using BCT tool. 

Could you please share the details of using/configuration PCIe Gen2 interface.

Hi @CarlosAM_INTEL,

Thanks for the response.

I couldn't find the x8 PCIe Gen2 bifurcation details in the document which you specified and also in the board setting file(BSF).

But I could see the configurable option of x24 PCIe Gen3 bifurcation in the BSF. 

x8 PCIe Gen2 lanes can't be configured using BSF?
