From aa66f08a21b791f338b519f0c2162cd8f7b3aeb0 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 11 Sep 2008 17:59:52 -0600 Subject: cell: initial support for fragment shader code generation. TGSI shaders are translated into SPE instructions which are then sent to the SPEs for execution. Only a few opcodes work, no swizzling yet, no support for constants/immediates, etc. --- src/gallium/drivers/cell/spu/spu_tri.c | 35 ++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) (limited to 'src/gallium/drivers/cell/spu/spu_tri.c') diff --git a/src/gallium/drivers/cell/spu/spu_tri.c b/src/gallium/drivers/cell/spu/spu_tri.c index f02cdd1f76..8b93878192 100644 --- a/src/gallium/drivers/cell/spu/spu_tri.c +++ b/src/gallium/drivers/cell/spu/spu_tri.c @@ -314,7 +314,42 @@ emit_quad( int x, int y, mask_t mask ) } else { /* simple shading */ +#if 0 eval_coeff(1, (float) x, (float) y, colors); + +#else + /* XXX new fragment program code */ + + if (spu.fragment_program) { + vector float inputs[4*4], outputs[2*4]; + + /* setup inputs */ + eval_coeff(1, (float) x, (float) y, inputs); + + /* Execute the current fragment program */ + spu.fragment_program(inputs, outputs, spu.constants); + + /* Copy outputs */ + colors[0] = outputs[0*4+0]; + colors[1] = outputs[0*4+1]; + colors[2] = outputs[0*4+2]; + colors[3] = outputs[0*4+3]; + + if (0 && spu.init.id==0 && y == 48) { + printf("colors[0] = %f %f %f %f\n", + spu_extract(colors[0], 0), + spu_extract(colors[0], 1), + spu_extract(colors[0], 2), + spu_extract(colors[0], 3)); + printf("colors[1] = %f %f %f %f\n", + spu_extract(colors[1], 0), + spu_extract(colors[1], 1), + spu_extract(colors[1], 2), + spu_extract(colors[1], 3)); + } + + } +#endif } -- cgit v1.2.3
