In order to have a useful Windows desktop, you need a DX12 driver.

So, in order to write their own KMD, they'd either have to also write their own DX12 driver, which they probably have no interest in, or reverse engineer the existing AMD KMD interface to the point where they can reimplement it basically completely so that AMD's proprietary DX12 driver runs on it.

I doubt they're saying it's impossible, it's more of a pick your battles situation.

You mean Vulkan driver. We can run DX12 on Vulkan.

Do you mean on Linux in a Wine/Proton context? That's different, so yes, I did mean DX12 driver.

Again, not impossible, just picking your battles.
