[Mesa-users] Why RADV requires AMDGPU and doesn't support Radeon?

[goleo at disroot.org]

Vulkan is supposed to work on GPUs that support OpenGL ES 3.1 or OpenGL 4.x and up, so why RADV doesn't work on pre-GCN cards and GCN 1.0 and 1.1 cards that use Radeon instead of AMDGPU driver? Do you think of people running old hardware and not having money and/or reasons to buy new one? What about people running *BSD where AMDGPU is either not present or buggy? What about people hating AMDGPU and preferring Radeon instead? Basically Vulkan is about lowering the gaming audience.
