What I find depressing is because of idiotic Linux policies, it turns out nvidia hardware is easier to run on a 3rd party OS than hardware with otherwise fully open source drivers like Radeon.
This is just yet another example that you may think things in the hardware world have changed now that Linux "rules", but they have not.
Are you talking about driver ABIs or something else?
What do you mean? BSDs have tons of code lifted from the Linux amdgpu driver.
