It's worth pointing out that apart from the display code (which is what this thread is about), the diff between amdgpu and amdgpu-pro is very small. Most of amdgpu (and hence amdgpu-pro) is actually very specific to Linux and shares no code with Windows.

From that perspective, saying that "the optimistic future is that AMD drops AMDGPU Pro" is a bit silly, since it's largely the same code base as AMDGPU and the same people working on both.

It also makes no sense at all to say that "a lot of what this HAL does has had usable support [...] in various parts of Gallium / Mesa", since Gallium and Mesa are purely concerned with rendering and video. They don't care about display. In fact, you can actually use radeonsi and the rest of the open-source stack on top of the amdgpu-pro kernel module. (And for that matter, the closed source Vulkan driver is supposed to be compatible with an otherwise open source stack.)

Also, AMDGPU is not necessarily fine going forward, precisely because of this display code issue. Yes, the memory management and rendering/video engine parts are going to be just fine, but that won't do you a lot of good (outside of compute purposes) if you can't light up a display...
