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_main.c | 25 ++++++++++++++++++++++++- 1 file changed, 24 insertions(+), 1 deletion(-) (limited to 'src/gallium/drivers/cell/spu/spu_main.c') diff --git a/src/gallium/drivers/cell/spu/spu_main.c b/src/gallium/drivers/cell/spu/spu_main.c index 2a7cb75f59..78260c4259 100644 --- a/src/gallium/drivers/cell/spu/spu_main.c +++ b/src/gallium/drivers/cell/spu/spu_main.c @@ -232,7 +232,7 @@ cmd_state_fragment_ops(const struct cell_command_fragment_ops *fops) printf("SPU %u: CMD_STATE_FRAGMENT_OPS\n", spu.init.id); /* Copy SPU code from batch buffer to spu buffer */ memcpy(spu.fragment_ops_code, fops->code, SPU_MAX_FRAGMENT_OPS_INSTS * 4); - /* Copy state info */ + /* Copy state info (for fallback case only) */ memcpy(&spu.depth_stencil_alpha, &fops->dsa, sizeof(fops->dsa)); memcpy(&spu.blend, &fops->blend, sizeof(fops->blend)); @@ -244,6 +244,21 @@ cmd_state_fragment_ops(const struct cell_command_fragment_ops *fops) } +static void +cmd_state_fragment_program(const struct cell_command_fragment_program *fp) +{ + if (Debug) + printf("SPU %u: CMD_STATE_FRAGMENT_PROGRAM\n", spu.init.id); + /* Copy SPU code from batch buffer to spu buffer */ + memcpy(spu.fragment_program_code, fp->code, + SPU_MAX_FRAGMENT_PROGRAM_INSTS * 4); +#if 01 + /* Point function pointer at new code */ + spu.fragment_program = (spu_fragment_program_func)spu.fragment_program_code; +#endif +} + + static void cmd_state_framebuffer(const struct cell_command_framebuffer *cmd) { @@ -473,6 +488,14 @@ cmd_batch(uint opcode) pos += sizeof(*fops) / 8; } break; + case CELL_CMD_STATE_FRAGMENT_PROGRAM: + { + struct cell_command_fragment_program *fp + = (struct cell_command_fragment_program *) &buffer[pos]; + cmd_state_fragment_program(fp); + pos += sizeof(*fp) / 8; + } + break; case CELL_CMD_STATE_SAMPLER: { struct cell_command_sampler *sampler -- cgit v1.2.3
