From c6499a741c99394e81d1d86ffd066f3d9749875c Mon Sep 17 00:00:00 2001 From: Brian Date: Mon, 5 Nov 2007 18:04:30 -0700 Subject: Determine GL extensions/limits by making pipe queries. The state tracker calls pipe->get_param() to determine the GL limits and which OpenGL extensions are supported. This is an initial implementation that'll probably change... --- src/mesa/pipe/i915simple/i915_context.c | 20 ++++++++++++++++++++ src/mesa/pipe/p_defines.h | 17 +++++++++++++++++ src/mesa/pipe/softpipe/sp_context.c | 20 ++++++++++++++++++++ 3 files changed, 57 insertions(+) (limited to 'src/mesa/pipe') diff --git a/src/mesa/pipe/i915simple/i915_context.c b/src/mesa/pipe/i915simple/i915_context.c index 2c36a194c7..6de1e68f73 100644 --- a/src/mesa/pipe/i915simple/i915_context.c +++ b/src/mesa/pipe/i915simple/i915_context.c @@ -142,6 +142,26 @@ static int i915_get_param(struct pipe_context *pipe, int param) { switch (param) { + case PIPE_CAP_MAX_TEXTURE_IMAGE_UNITS: + return 8; + case PIPE_CAP_NPOT_TEXTURES: + return 1; + case PIPE_CAP_TWO_SIDED_STENCIL: + return 1; + case PIPE_CAP_GLSL: + return 0; + case PIPE_CAP_S3TC: + return 0; + case PIPE_CAP_ANISOTROPIC_FILTER: + return 0; + case PIPE_CAP_POINT_SPRITE: + return 0; + case PIPE_CAP_MAX_RENDER_TARGETS: + return 1; + case PIPE_CAP_OCCLUSION_QUERY: + return 0; + case PIPE_CAP_TEXTURE_SHADOW_MAP: + return 0; default: return 0; } diff --git a/src/mesa/pipe/p_defines.h b/src/mesa/pipe/p_defines.h index 8982428636..ef79716ed9 100644 --- a/src/mesa/pipe/p_defines.h +++ b/src/mesa/pipe/p_defines.h @@ -225,4 +225,21 @@ #define PIPE_SPRITE_COORD_UPPER_LEFT 1 #define PIPE_SPRITE_COORD_LOWER_LEFT 2 + +/** + * Implementation capabilities/limits + * Passed to pipe->get_param() + * XXX this will need some fine tuning... + */ +#define PIPE_CAP_MAX_TEXTURE_IMAGE_UNITS 1 +#define PIPE_CAP_NPOT_TEXTURES 2 +#define PIPE_CAP_TWO_SIDED_STENCIL 3 +#define PIPE_CAP_GLSL 4 /* XXX need something better */ +#define PIPE_CAP_S3TC 5 +#define PIPE_CAP_ANISOTROPIC_FILTER 6 +#define PIPE_CAP_POINT_SPRITE 7 +#define PIPE_CAP_MAX_RENDER_TARGETS 8 +#define PIPE_CAP_OCCLUSION_QUERY 9 +#define PIPE_CAP_TEXTURE_SHADOW_MAP 10 + #endif diff --git a/src/mesa/pipe/softpipe/sp_context.c b/src/mesa/pipe/softpipe/sp_context.c index 46f591e425..effecda87e 100644 --- a/src/mesa/pipe/softpipe/sp_context.c +++ b/src/mesa/pipe/softpipe/sp_context.c @@ -277,6 +277,26 @@ static const char *softpipe_get_vendor( struct pipe_context *pipe ) static int softpipe_get_param(struct pipe_context *pipe, int param) { switch (param) { + case PIPE_CAP_MAX_TEXTURE_IMAGE_UNITS: + return 8; + case PIPE_CAP_NPOT_TEXTURES: + return 1; + case PIPE_CAP_TWO_SIDED_STENCIL: + return 1; + case PIPE_CAP_GLSL: + return 1; + case PIPE_CAP_S3TC: + return 0; + case PIPE_CAP_ANISOTROPIC_FILTER: + return 0; + case PIPE_CAP_POINT_SPRITE: + return 1; + case PIPE_CAP_MAX_RENDER_TARGETS: + return 1; + case PIPE_CAP_OCCLUSION_QUERY: + return 1; + case PIPE_CAP_TEXTURE_SHADOW_MAP: + return 1; default: return 0; } -- cgit v1.2.3
