PCIe endpoint dma driver usage example

I read

Режим конечной точки PCIe.

It’s great that Nvidia has implemented a functional driver.
but how sad it is that utilities are used for testing PCI.
A small test program code that shows how to use the driver would be very useful, perhaps there is a similar example somewhere? Or at least some documentation on this driver - I’m interested in the DMA driver for endpoint.

Rel-36 does not have sufficient driver yet. It would have driver added in next release.

Rel-35 has pci-epf-tegra-vnet.c as reference.

I found in 35.5 pci-epf-dma-test.c. Is there at least some description or simple example of its use?

please refer to
