Check which GPU a process is using

I have a notebook with an Intel iGPU and a dedicated AMD GPU and I was told that by default the iGPU would be used, but that I can explicitly tell a program use the AMD GPU by running it like this

DRI_PRIME=1 example_program

I know that this works for glmark2 because it tells me in the terminal, but how can I verify this for any other process?

For nvidia GPUs there apparently is a utility called nvidia-smi, but I need something that works for AMD GPUs.

I’m using Fedora 34 in case it matters…
