From 92126cea846959bb2152905a7712753d1114bd6b Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Wed, 26 Mar 2008 10:45:32 -0700 Subject: [PATCH] cell: Implement code-gen for logic op This also implements code-gen for the float-to-packed color conversion. It's currently hardcoded for A8R8G8B8, but that can easily be fixed as soon as other color depths are supported by the Cell driver. --- src/gallium/drivers/cell/common.h | 11 +- src/gallium/drivers/cell/ppu/cell_context.h | 2 + src/gallium/drivers/cell/ppu/cell_state_emit.c | 17 ++ .../drivers/cell/ppu/cell_state_per_fragment.c | 261 ++++++++++++++++++++- .../drivers/cell/ppu/cell_state_per_fragment.h | 4 + src/gallium/drivers/cell/spu/spu_main.c | 19 ++ src/gallium/drivers/cell/spu/spu_main.h | 9 +- src/gallium/drivers/cell/spu/spu_tri.c | 59 +++-- 8 files changed, 349 insertions(+), 33 deletions(-) diff --git a/src/gallium/drivers/cell/common.h b/src/gallium/drivers/cell/common.h index d59e4f7..b0928fe 100644 --- a/src/gallium/drivers/cell/common.h +++ b/src/gallium/drivers/cell/common.h @@ -92,8 +92,9 @@ #define CELL_CMD_STATE_BIND_VS 18 #define CELL_CMD_STATE_BLEND 19 #define CELL_CMD_STATE_ATTRIB_FETCH 20 -#define CELL_CMD_VS_EXECUTE 21 -#define CELL_CMD_FLUSH_BUFFER_RANGE 22 +#define CELL_CMD_STATE_LOGICOP 21 +#define CELL_CMD_VS_EXECUTE 22 +#define CELL_CMD_FLUSH_BUFFER_RANGE 23 #define CELL_NUM_BUFFERS 4 @@ -124,6 +125,12 @@ struct cell_command_blend { }; +struct cell_command_logicop { + uint64_t base; /**< Effective address of code start. */ + unsigned size; /**< Size in bytes of test code. */ +}; + + /** * Tell SPUs about the framebuffer size, location */ diff --git a/src/gallium/drivers/cell/ppu/cell_context.h b/src/gallium/drivers/cell/ppu/cell_context.h index 9e79db0..0442abd 100644 --- a/src/gallium/drivers/cell/ppu/cell_context.h +++ b/src/gallium/drivers/cell/ppu/cell_context.h @@ -92,6 +92,8 @@ struct cell_context const struct cell_vertex_shader_state *vs; const struct cell_fragment_shader_state *fs; + struct spe_function logic_op; + struct pipe_blend_color blend_color; struct pipe_clip_state clip; struct pipe_constant_buffer constants[2]; diff --git a/src/gallium/drivers/cell/ppu/cell_state_emit.c b/src/gallium/drivers/cell/ppu/cell_state_emit.c index 5709b48..5c1310d 100644 --- a/src/gallium/drivers/cell/ppu/cell_state_emit.c +++ b/src/gallium/drivers/cell/ppu/cell_state_emit.c @@ -50,6 +50,23 @@ emit_state_cmd(struct cell_context *cell, uint cmd, void cell_emit_state(struct cell_context *cell) { + if (cell->dirty & (CELL_NEW_FRAMEBUFFER | CELL_NEW_BLEND)) { + struct cell_command_logicop logicop; + + if (cell->logic_op.store != NULL) { + spe_release_func(& cell->logic_op); + } + + cell_generate_logic_op(& cell->logic_op, + & cell->blend->base, + cell->framebuffer.cbufs[0]); + + logicop.base = (intptr_t) cell->logic_op.store; + logicop.size = 64 * 4; + emit_state_cmd(cell, CELL_CMD_STATE_LOGICOP, &logicop, + sizeof(logicop)); + } + if (cell->dirty & CELL_NEW_FRAMEBUFFER) { struct pipe_surface *cbuf = cell->framebuffer.cbufs[0]; struct pipe_surface *zbuf = cell->framebuffer.zsbuf; diff --git a/src/gallium/drivers/cell/ppu/cell_state_per_fragment.c b/src/gallium/drivers/cell/ppu/cell_state_per_fragment.c index c750b1d..f10025b 100644 --- a/src/gallium/drivers/cell/ppu/cell_state_per_fragment.c +++ b/src/gallium/drivers/cell/ppu/cell_state_per_fragment.c @@ -977,7 +977,6 @@ cell_generate_alpha_blend(struct cell_blend_state *cb) spe_allocate_register(f, 13), spe_allocate_register(f, 14), }; - const int mask = spe_allocate_register(f, 15); unsigned func[4]; unsigned sF[4]; unsigned dF[4]; @@ -1114,9 +1113,6 @@ cell_generate_alpha_blend(struct cell_blend_state *cb) func[i], sF[i], dF[i], frag[i], src_factor[i], pixel[i], dst_factor[i]); - spe_selb(f, frag[i], pixel[i], frag[i], mask); - } else { - spe_or(f, frag[i], pixel[i], pixel[i]); } } @@ -1146,3 +1142,260 @@ cell_generate_alpha_blend(struct cell_blend_state *cb) } #endif } + + +int PC_OFFSET(const struct spe_function *f, const void *d) +{ + const intptr_t pc = (intptr_t) f->csr; + const intptr_t ea = ~0x0f & (intptr_t) d; + + return (ea - pc) >> 2; +} + + +/** + * Generate code to perform color conversion and logic op + * + * \bug + * The code generated by this function should also perform dithering. + * + * \bug + * The code generated by this function should also perform color-write + * masking. + * + * \bug + * This routine is hard-coded to only work with ARGB8 data. + */ +void +cell_generate_logic_op(struct spe_function *f, struct pipe_blend_state *blend, + struct pipe_surface *surf) +{ + const unsigned logic_op = (blend->logicop_enable) + ? blend->logicop_func : PIPE_LOGICOP_COPY; + + /* This code generates a maximum of 37 instructions.
