Now we support all the vertex formats! This means we don't hit u_vbuf for format translation, which helps performance in lots of applications. By doing the lowering in NIR, the vertex fetch code itself can be optimized by NIR (e.g. nir_opt_algebraic) which can improve generated code quality. In my first implementation of this, I had a big switch statement mapping format enums to interchange formats and post-processing code. This ends up being really unwieldly, the combinatorics of bit packing + conversion + swizzles is enormous and for performance we want to support everything (no u_vbuf fallbacks). To keep the combinatorics in check, we rely on parsing the util_format_description to separate out the issues of bit packing, conversion, and swizzling, allowing us to handle bizarro formats like B10G10R10A2_SNORM with no special casing. In an effort to support everything in one shot, this handles all the formats needed for the extensions EXT_vertex_array_bgra, ARB_vertex_type_2_10_10_10_rev, and ARB_vertex_type_10f_11f_11f_rev. Passes dEQP-GLES3.functional.vertex_arrays.* Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/19996> |
