this is sorta true, but not quite amdgpu is the underlying open source kernel module -- it's in the mainline kernel. mesa is the open source userland driver, and runs atop the amdgpu kernel driver amdgpu pro is the closed source userland driver, which also runs atop the open amdgpu kernel driver. what's really nice about this is that you can run a fully open source stack in your host os while running amdgpu pro/rocm inside a container.
