nothing at all.  as i said: SwiftShader has been specifically designed with
complete lack of consideration for 3D-hardware-accelerated instruction sets.

the 3D MESA driver therefore needs to be based on one of the following:

* the AMDVLK driver (unlikely because it's a rather rocky/kludged port of a
Win32 driver)
* the MESA RADV driver (which involves removing the "thunk" layer between MESA
and LLVM)
* the original Intel NIR driver and porting it i.e. following the path blazed
by RADV many years ago (RADV was a port of the *Intel* MESA driver to AMDGPU).

there are downsides and benefits to each: these all need to be discussed.
