Stratix 10 CVP - how to write an image from userspace?

Stratix 10 CVP - how to write an image from userspace?

[Chris Dot]

Hi, I have a Stratix 10 PCIe FPGA card and I want to program it over CVP.

How do I do that? Would I write (dd?) to some sysfs node, use ioctls?
Any help appreciated.

Below is my workspace. This is kernel 5.4.
