Hi,

At the moment, GPU passthrough is not fully supported by bhyve. I'm
working on it.

The current situation for dedicated AMD GPUs (on 13.2 and 14-CURRENT):
* Windows
  * It should work
* Linux
  * Requires a VBIOS
  * You have to use UEFI boot with a patched OVMF

I had some issues when using an integrated AMD GPU. I was using a CPU
of the Ryzen Embedded V1000 series. Maybe you have more luck with your
AMD Pro series.
