From 1407daf9bc9e0452a171aaca2ab8e389ccca5462 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 20 Apr 2010 12:26:49 -0700 Subject: [PATCH] i915: Map sampler indices to texture units correctly for fragment shaders. Fixes hang with "gst-launch-0.10 videotestsrc ! video/x-raw-rgb ! glupload ! gleffects effect=heat ! glimagesink" which uses 2 samplers pointing at GL_TEXTURE1 and GL_TEXTURE2, and piglit glsl-fs-sampler-numbering. --- src/mesa/drivers/dri/i915/i915_fragprog.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i915/i915_fragprog.c b/src/mesa/drivers/dri/i915/i915_fragprog.c index 906d5855a75..9f12e2c632e 100644 --- a/src/mesa/drivers/dri/i915/i915_fragprog.c +++ b/src/mesa/drivers/dri/i915/i915_fragprog.c @@ -255,8 +255,10 @@ translate_tex_src_target(struct i915_fragment_program *p, GLubyte bit) #define EMIT_TEX( OP ) \ do { \ GLuint dim = translate_tex_src_target( p, inst->TexSrcTarget ); \ + const struct gl_fragment_program *program = p->ctx->FragmentProgram._Current; \ + GLuint unit = program->Base.SamplerUnits[inst->TexSrcUnit]; \ GLuint sampler = i915_emit_decl(p, REG_TYPE_S, \ - inst->TexSrcUnit, dim); \ + unit, dim); \ GLuint coord = src_vector( p, &inst->SrcReg[0], program); \ /* Texel lookup */ \ \ -- 2.30.2
