@alexniver can you post a dump of wgpu-info --verbose? might be helpful to understand why it wouldn't pick your amd gpu
also a RUST_LOG=trace of the portion on hello_triangle that shows the adapter selection

That warning from mesa is exactly why it's not letting your and card through. Radv isn't conformant on your amd card, and we filter out all non-conformant implementations by default, falling back in opengl, where we can't actually pick which adapter we get.

oh, I know, so this is not a issue, I will close.
