PIPE_CAP_PACKED_UNIFORMS conflates several things: Lowering uniforms i/o at the st level instead of the backend, packing uniforms with no padding at all, and lowering to UBOs. Requiring backends to lower uniforms i/o for !PIPE_CAP_PACKED_UNIFORMS leads to the driver needing to either link against the type size function in mesa/st, or duplicating it in the backend. Given that all backends want this lower-io as far as I can tell, just move it to mesa/st to resolve the link issue and avoid the driver author needing to understand st's uniforms layout. Incidentally, fixes uniform layout failures in nouveau in: dEQP-GLES2.functional.shaders.struct.uniform.sampler_nested_fragment dEQP-GLES2.functional.shaders.struct.uniform.sampler_nested_vertex dEQP-GLES2.functional.shaders.struct.uniform.sampler_array_fragment dEQP-GLES2.functional.shaders.struct.uniform.sampler_array_vertex and I think in Lima as well. v2: fix indents Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
