Agilex 5 | GTS AXI Streaming for PCIe Design Example | Pairing drivers

Hello,

Looking to understand more about the "GTS AXI Streaming Intel® FPGA IP
for PCI Express* Design Example" for use in Agilex 5, particularly in a PCIe x1 configuration.

I see there's a driver provided per section 2.7 of the user guide (RDC doc. 817713) that's limited in operations per section 2.8.

Wondering - are there other Intel/Altera provided drivers with greater feature set? Are there third-party drivers pairing well that can be recommended?

Thanks in advance,
