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/ppu/cell_state_emit.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'src/gallium/drivers/cell/ppu/cell_state_emit.c') diff --git a/src/gallium/drivers/cell/ppu/cell_state_emit.c b/src/gallium/drivers/cell/ppu/cell_state_emit.c index 3ebf0749ad..2da3097983 100644 --- a/src/gallium/drivers/cell/ppu/cell_state_emit.c +++ b/src/gallium/drivers/cell/ppu/cell_state_emit.c @@ -73,6 +73,22 @@ cell_emit_state(struct cell_context *cell) #endif } + if (cell->dirty & (CELL_NEW_FS)) { + /* Send new fragment program to SPUs */ + struct cell_command_fragment_program *fp + = cell_batch_alloc(cell, sizeof(*fp)); + fp->opcode = CELL_CMD_STATE_FRAGMENT_PROGRAM; + fp->num_inst = cell->fs->code.num_inst; + memcpy(&fp->code, cell->fs->code.store, + SPU_MAX_FRAGMENT_PROGRAM_INSTS * SPE_INST_SIZE); + if (0) { + int i; + printf("PPU Emit CELL_CMD_STATE_FRAGMENT_PROGRAM:\n"); + for (i = 0; i < fp->num_inst; i++) { + printf(" %3d: 0x%08x\n", i, fp->code[i]); + } + } + } if (cell->dirty & (CELL_NEW_FRAMEBUFFER | CELL_NEW_DEPTH_STENCIL | -- cgit v1.2.3
