From 1936e4bdfd776f78f9fe44f77ce66066fd166360 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 17 Mar 2008 15:45:52 -0700 Subject: cell: Initial code-gen for alpha / stencil / depth testing Alpha test is currently broken because all per-fragment testing occurs before alpha is calculated. Stencil test is currently broken because the Z-clear code asserts if there is a stencil buffer. --- src/gallium/drivers/cell/ppu/cell_context.h | 25 +++++++++++++++++++++++-- 1 file changed, 23 insertions(+), 2 deletions(-) (limited to 'src/gallium/drivers/cell/ppu/cell_context.h') diff --git a/src/gallium/drivers/cell/ppu/cell_context.h b/src/gallium/drivers/cell/ppu/cell_context.h index b221424323..9e79db0ace 100644 --- a/src/gallium/drivers/cell/ppu/cell_context.h +++ b/src/gallium/drivers/cell/ppu/cell_context.h @@ -57,16 +57,37 @@ struct cell_fragment_shader_state }; +struct cell_blend_state { + struct pipe_blend_state base; + + /** + * Generated code to perform alpha blending + */ + struct spe_function code; +}; + + +struct cell_depth_stencil_alpha_state { + struct pipe_depth_stencil_alpha_state base; + + /** + * Generated code to perform alpha, stencil, and depth testing on the SPE + */ + struct spe_function code; + +}; + + struct cell_context { struct pipe_context pipe; struct cell_winsys *winsys; - const struct pipe_blend_state *blend; + const struct cell_blend_state *blend; const struct pipe_sampler_state *sampler[PIPE_MAX_SAMPLERS]; uint num_samplers; - const struct pipe_depth_stencil_alpha_state *depth_stencil; + const struct cell_depth_stencil_alpha_state *depth_stencil; const struct pipe_rasterizer_state *rasterizer; const struct cell_vertex_shader_state *vs; const struct cell_fragment_shader_state *fs; -- cgit v1.2.3
