Author: Luca Barbieri <[email protected]> Date: Mon Jan 11 01:09:44 2010 +0100 nvfx: Add support for two sided color This patch adds support for two-sided vertex color to nv30/nv40. When set, the COLOR0/1 fs inputs on back faces will be wired to vs outputs BCOLOR0/1. This makes OpenGL two sided lighting work, which can be tested with progs/demos/projtex. --- src/gallium/drivers/nvfx/nvfx_context.h | 2 +- src/gallium/drivers/nvfx/nvfx_state.c | 4 +++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/src/gallium/drivers/nvfx/nvfx_context.h b/src/gallium/drivers/nvfx/nvfx_context.h index fea05ac..e2c6d09 100644 --- a/src/gallium/drivers/nvfx/nvfx_context.h +++ b/src/gallium/drivers/nvfx/nvfx_context.h @@ -46,7 +46,7 @@ struct nvfx_rasterizer_state { struct pipe_rasterizer_state pipe; unsigned sb_len; - uint32_t sb[30]; + uint32_t sb[32]; }; struct nvfx_zsa_state { diff --git a/src/gallium/drivers/nvfx/nvfx_state.c b/src/gallium/drivers/nvfx/nvfx_state.c index 0f03c2e..315de49 100644 --- a/src/gallium/drivers/nvfx/nvfx_state.c +++ b/src/gallium/drivers/nvfx/nvfx_state.c @@ -193,7 +193,6 @@ nvfx_rasterizer_state_create(struct pipe_context *pipe, struct nouveau_statebuf_builder sb = sb_init(rsso->sb); /*XXX: ignored: - * light_twoside * point_smooth -nohw * multisample */ @@ -202,6 +201,9 @@ nvfx_rasterizer_state_create(struct pipe_context *pipe, sb_data(sb, cso->flatshade ?
