This is silly, but for now it makes mesa-demos/glsl/pointcoord work. --- diff --git a/src/gallium/drivers/nvfx/nvfx_fragprog.c b/src/gallium/drivers/nvfx/nvfx_fragprog.c index 23a85c9342e..049b814d49f 100644 --- a/src/gallium/drivers/nvfx/nvfx_fragprog.c +++ b/src/gallium/drivers/nvfx/nvfx_fragprog.c @@ -1181,8 +1181,11 @@ nvfx_fragprog_validate(struct nvfx_context *nvfx) struct nouveau_channel* chan = nvfx->screen->base.channel; struct nvfx_pipe_fragment_program *pfp = nvfx->fragprog; struct nvfx_vertex_program* vp; - unsigned sprite_coord_enable = nvfx->rasterizer->pipe.point_quad_rasterization * nvfx->rasterizer->pipe.sprite_coord_enable; - // TODO: correct or flipped? + /* Gallium always puts the point coord in GENERIC[0] + * TODO: this is wrong, Gallium needs to be fixed + */ + unsigned sprite_coord_enable = nvfx->rasterizer->pipe.point_quad_rasterization * (nvfx->rasterizer->pipe.sprite_coord_enable | 1); + boolean emulate_sprite_flipping = sprite_coord_enable && nvfx->rasterizer->pipe.sprite_coord_mode; unsigned key = emulate_sprite_flipping; struct nvfx_fragment_program* fp;
