From 763e30748e99064fafeb0d9b34de8d732732689c Mon Sep 17 00:00:00 2001 From: Brian Date: Thu, 10 Jan 2008 15:14:58 -0700 Subject: [PATCH] Cell: initial implementation of vbuf code. The draw module's vbuf stage builds buffers of post-transformed vertices and issues draw-elements calls to render them. We'll pass the vertex and index buffers to the SPUs... --- src/mesa/pipe/cell/ppu/Makefile | 1 + src/mesa/pipe/cell/ppu/cell_context.c | 8 +- src/mesa/pipe/cell/ppu/cell_context.h | 6 ++ src/mesa/pipe/cell/ppu/cell_vbuf.c | 136 ++++++++++++++++++++++++++++++++++ src/mesa/pipe/cell/ppu/cell_vbuf.h | 38 ++++++++++ 5 files changed, 188 insertions(+), 1 deletion(-) create mode 100644 src/mesa/pipe/cell/ppu/cell_vbuf.c create mode 100644 src/mesa/pipe/cell/ppu/cell_vbuf.h diff --git a/src/mesa/pipe/cell/ppu/Makefile b/src/mesa/pipe/cell/ppu/Makefile index 2758e1b..9bf8970 100644 --- a/src/mesa/pipe/cell/ppu/Makefile +++ b/src/mesa/pipe/cell/ppu/Makefile @@ -30,6 +30,7 @@ SOURCES = \ cell_state_vertex.c \ cell_spu.c \ cell_surface.c \ + cell_vbuf.c \ cell_winsys.c diff --git a/src/mesa/pipe/cell/ppu/cell_context.c b/src/mesa/pipe/cell/ppu/cell_context.c index fee72ea..091e593 100644 --- a/src/mesa/pipe/cell/ppu/cell_context.c +++ b/src/mesa/pipe/cell/ppu/cell_context.c @@ -46,6 +46,7 @@ #include "cell_state.h" #include "cell_surface.h" #include "cell_spu.h" +#include "cell_vbuf.h" @@ -236,9 +237,14 @@ cell_create_context(struct pipe_winsys *winsys, struct cell_winsys *cws) cell->draw = draw_create();
