From bf5ee5aa4f065b6e17a4cc9cd2e539c4290ff98c Mon Sep 17 00:00:00 2001 From: Luca Barbieri Date: Fri, 6 Aug 2010 00:58:48 +0200 Subject: nvfx: fix nv30 vertex program scalar opcodes Apparently they have always been broken, even before unification. Fixes a lot of stuff, starting from morph3d and lighting in teapot with textures disabled. --- src/gallium/drivers/nvfx/nvfx_vertprog.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/gallium/drivers/nvfx/nvfx_vertprog.c') diff --git a/src/gallium/drivers/nvfx/nvfx_vertprog.c b/src/gallium/drivers/nvfx/nvfx_vertprog.c index 80b98b62d34..24d9846310e 100644 --- a/src/gallium/drivers/nvfx/nvfx_vertprog.c +++ b/src/gallium/drivers/nvfx/nvfx_vertprog.c @@ -299,7 +299,13 @@ nvfx_vp_arith(struct nvfx_context* nvfx, struct nvfx_vpc *vpc, int slot, int op, (3 << NVFX_VP(INST_COND_SWZ_W_SHIFT))); if(!nvfx->is_nv4x) { - hw[1] |= (op << NV30_VP_INST_VEC_OPCODE_SHIFT); + if(slot == 0) + hw[1] |= (op << NV30_VP_INST_VEC_OPCODE_SHIFT); + else + { + hw[0] |= ((op >> 4) << NV30_VP_INST_SCA_OPCODEH_SHIFT); + hw[1] |= ((op & 0xf) << NV30_VP_INST_SCA_OPCODEL_SHIFT); + } // hw[3] |= NVFX_VP(INST_SCA_DEST_TEMP_MASK); // hw[3] |= (mask << NVFX_VP(INST_VEC_WRITEMASK_SHIFT)); -- cgit v1.2.3
