From 8e4a95a93d15a6707a29454cd47e10b08314cda2 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Thu, 24 May 2007 10:41:34 +0100 Subject: First version of the softpipe rasterizer. This will flesh out to hopefully acheive 3 things: - New software rasterizer for mesa - New driver model for mesa & dri with much smaller drivers - The basis for the cell driver. It's got a long way to go yet, but will at least run trivial/tri.c. --- src/mesa/softpipe/state_tracker/st_context.h | 109 +++++++++++++++++++++++++++ 1 file changed, 109 insertions(+) create mode 100644 src/mesa/softpipe/state_tracker/st_context.h (limited to 'src/mesa/softpipe/state_tracker/st_context.h') diff --git a/src/mesa/softpipe/state_tracker/st_context.h b/src/mesa/softpipe/state_tracker/st_context.h new file mode 100644 index 0000000000..08cee11797 --- /dev/null +++ b/src/mesa/softpipe/state_tracker/st_context.h @@ -0,0 +1,109 @@ +/************************************************************************** + * + * Copyright 2003 Tungsten Graphics, Inc., Cedar Park, Texas. + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the + * "Software"), to deal in the Software without restriction, including + * without limitation the rights to use, copy, modify, merge, publish, + * distribute, sub license, and/or sell copies of the Software, and to + * permit persons to whom the Software is furnished to do so, subject to + * the following conditions: + * + * The above copyright notice and this permission notice (including the + * next paragraph) shall be included in all copies or substantial portions + * of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. + * IN NO EVENT SHALL TUNGSTEN GRAPHICS AND/OR ITS SUPPLIERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, + * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE + * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + * + **************************************************************************/ + +#ifndef ST_CONTEXT_H +#define ST_CONTEXT_H + +#include "mtypes.h" +#include "softpipe/sp_state.h" + + +struct st_context; +struct st_region; +struct st_texture_object; +struct st_texture_image; +struct st_fragment_program; + +#define ST_NEW_MESA 0x1 /* Mesa state has changed */ +#define ST_NEW_FRAGMENT_PROGRAM 0x2 + +struct st_state_flags { + GLuint mesa; + GLuint st; +}; + +struct st_tracked_state { + struct st_state_flags dirty; + void (*update)( struct st_context *st ); +}; + + + + +struct st_context +{ + GLcontext *ctx; + + struct softpipe_context *softpipe; + + /* Eventually will use a cache to feed the softpipe with + * create/bind/delete calls to constant state objects.
