So the issue here is that (a) AoA isn't supported in mesa, (b) even if it was, the shader doesn't enable it. Without that, you can't have plain per-vertex array outputs in TCS. You could force-enable it by setting force_glsl_extensions_warn=1 and MESA_EXTENSION_OVERRIDE=GL_ARB_arrays_of_arrays ... I think.
