From 15d1b406afd733b5f46b16dc933e29c218cdca39 Mon Sep 17 00:00:00 2001 From: Michal Krol Date: Tue, 1 Dec 2009 08:33:43 +0100 Subject: [PATCH] gallium: Introduce separate vertex texture/sampler state. Previously, gallium shared sampler and texture state between vertex and fragment shader stages. This change generalises this concept by providing separate entrypoints for vertex and fragment sampler state setting. A new capability bit is added to query the driver for the number of samplers that can be utilised by a vertex and fragment shader at the same time. --- src/gallium/include/pipe/p_context.h | 17 +++++++++++++---- src/gallium/include/pipe/p_defines.h | 2 ++ src/gallium/include/pipe/p_state.h | 1 + 3 files changed, 16 insertions(+), 4 deletions(-) diff --git a/src/gallium/include/pipe/p_context.h b/src/gallium/include/pipe/p_context.h index 5569001e601..f896001eb12 100644 --- a/src/gallium/include/pipe/p_context.h +++ b/src/gallium/include/pipe/p_context.h @@ -123,7 +123,12 @@ struct pipe_context { void * (*create_sampler_state)(struct pipe_context *, const struct pipe_sampler_state *); - void (*bind_sampler_states)(struct pipe_context *, unsigned num, void **); + void (*bind_fragment_sampler_states)(struct pipe_context *, + unsigned num_samplers, + void **samplers); + void (*bind_vertex_sampler_states)(struct pipe_context *, + unsigned num_samplers, + void **samplers); void (*delete_sampler_state)(struct pipe_context *, void *); void * (*create_rasterizer_state)(struct pipe_context *, @@ -173,9 +178,13 @@ struct pipe_context { void (*set_viewport_state)( struct pipe_context *, const struct pipe_viewport_state * ); - void (*set_sampler_textures)( struct pipe_context *, - unsigned num_textures, - struct pipe_texture ** ); + void (*set_fragment_sampler_textures)(struct pipe_context *, + unsigned num_textures, + struct pipe_texture **); + + void (*set_vertex_sampler_textures)(struct pipe_context *, + unsigned num_textures, + struct pipe_texture **); void (*set_vertex_buffers)( struct pipe_context *, unsigned num_buffers, diff --git a/src/gallium/include/pipe/p_defines.h b/src/gallium/include/pipe/p_defines.h index fd14dc8e92d..69a0970d5f8 100644 --- a/src/gallium/include/pipe/p_defines.h +++ b/src/gallium/include/pipe/p_defines.h @@ -390,6 +390,8 @@ enum pipe_transfer_usage { #define PIPE_CAP_BLEND_EQUATION_SEPARATE 28 #define PIPE_CAP_SM3 29 /*< Shader Model 3 supported */ #define PIPE_CAP_MAX_PREDICATE_REGISTERS 30 +#define PIPE_CAP_MAX_COMBINED_SAMPLERS 31 /*< Maximum texture image units accessible from vertex + and fragment shaders combined */ /** diff --git a/src/gallium/include/pipe/p_state.h b/src/gallium/include/pipe/p_state.h index 9766e86620c..6de7af6a81c 100644 --- a/src/gallium/include/pipe/p_state.h +++ b/src/gallium/include/pipe/p_state.h @@ -60,6 +60,7 @@ extern "C" { #define PIPE_MAX_COLOR_BUFS 8 #define PIPE_MAX_CONSTANT 32 #define PIPE_MAX_SAMPLERS 16 +#define PIPE_MAX_VERTEX_SAMPLERS 16 #define PIPE_MAX_SHADER_INPUTS 16 #define PIPE_MAX_SHADER_OUTPUTS 16 #define PIPE_MAX_TEXTURE_LEVELS 16 -- 2.30.2
