From ce4659e92acfbb0ff8a93a6e619c44b839505ca9 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Tue, 21 Aug 2007 19:46:48 +0100 Subject: First pass at a fallback concept for pipe devices. Creates a new pipe driver that feeds commands to either a hardware or software pipe depending on fallback state. Untested concept checkpoint. At this point it compiles. --- src/mesa/pipe/failover/fo_context.h | 113 ++++++++++++++++++++++++++++++++++++ 1 file changed, 113 insertions(+) create mode 100644 src/mesa/pipe/failover/fo_context.h (limited to 'src/mesa/pipe/failover/fo_context.h') diff --git a/src/mesa/pipe/failover/fo_context.h b/src/mesa/pipe/failover/fo_context.h new file mode 100644 index 00000000000..5666d4e8306 --- /dev/null +++ b/src/mesa/pipe/failover/fo_context.h @@ -0,0 +1,113 @@ +/************************************************************************** + * + * Copyright 2007 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. + * + **************************************************************************/ + +/* Authors: Keith Whitwell + */ + +#ifndef FO_CONTEXT_H +#define FO_CONTEXT_H + +#include "pipe/p_state.h" +#include "pipe/p_context.h" + + + +#define FO_NEW_VIEWPORT 0x1 +#define FO_NEW_SETUP 0x2 +#define FO_NEW_FRAGMENT_SHADER 0x4 +#define FO_NEW_BLEND 0x8 +#define FO_NEW_CLIP 0x10 +#define FO_NEW_SCISSOR 0x20 +#define FO_NEW_STIPPLE 0x40 +#define FO_NEW_FRAMEBUFFER 0x80 +#define FO_NEW_ALPHA_TEST 0x100 +#define FO_NEW_DEPTH_TEST 0x200 +#define FO_NEW_SAMPLER 0x400 +#define FO_NEW_TEXTURE 0x800 +#define FO_NEW_STENCIL 0x1000 +#define FO_NEW_VERTEX 0x2000 +#define FO_NEW_VERTEX_SHADER 0x4000 +#define FO_NEW_BLEND_COLOR 0x8000 +#define FO_NEW_CLEAR_COLOR 0x10000 +#define FO_NEW_VERTEX_BUFFER 0x20000 +#define FO_NEW_VERTEX_ELEMENT 0x40000 + + + +#define FO_HW 0 +#define FO_SW 1 + +struct failover_context { + struct pipe_context pipe; /**< base class */ + + + /* The most recent drawing state as set by the driver: + */ + struct pipe_alpha_test_state alpha_test; + struct pipe_blend_state blend; + struct pipe_blend_color blend_color; + struct pipe_clear_color_state clear_color; + struct pipe_clip_state clip; + struct pipe_depth_state depth_test; + struct pipe_framebuffer_state framebuffer; + struct pipe_shader_state fragment_shader; + struct pipe_shader_state vertex_shader; + struct pipe_poly_stipple poly_stipple; + struct pipe_scissor_state scissor; + struct pipe_sampler_state sampler[PIPE_MAX_SAMPLERS]; + struct pipe_setup_state setup; + struct pipe_stencil_state stencil; + struct pipe_mipmap_tree *texture[PIPE_MAX_SAMPLERS]; + struct pipe_viewport_state viewport; + struct pipe_vertex_buffer vertex_buffer[PIPE_ATTRIB_MAX]; + struct pipe_vertex_element vertex_element[PIPE_ATTRIB_MAX]; + + unsigned dirty; + unsigned dirty_sampler; + unsigned dirty_texture; + unsigned dirty_vertex_buffer; + unsigned dirty_vertex_element; + + + unsigned mode; + struct pipe_context *hw; + struct pipe_context *sw; +}; + + + +void failover_init_state_functions( struct failover_context *failover ); +void failover_state_emit( struct failover_context *failover ); + +static INLINE struct failover_context * +failover_context( struct pipe_context *pipe ) +{ + return (struct failover_context *)pipe; +} + + +#endif /* FO_CONTEXT_H */ -- cgit v1.2.3
