No, it is just listed because the llvmpipe driver was developed by
VMWare. You can see this for yourself, setting LIBGL_ALWAYS_SOFTWARE=1
in the environment makes libgl use the llvmpipe driver:
,----
| LIBGL_ALWAYS_SOFTWARE=1 glxinfo | grep OpenGL | head -n2
| OpenGL vendor string: VMware, Inc.
| OpenGL renderer string: llvmpipe (LLVM 10.0.0, 128 bits)
`----
Why in the OP's system the llvmpipe driver is used instead of r200, I
don't know. Maybe firmware-amd-graphics is not installed, although the
logs suggest to me that it is.
