From e78a6aa2b94683faa8d43a39aa68d806b14f8833 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 20 May 2009 14:16:34 -0700 Subject: intel: Fall back on any rendering to texture with no miptree. Fixes segfault on an fbo.c negative test for FBO with texture width/height of 0. Previously we just tested for border != 0 to work around this segfault. --- src/mesa/drivers/dri/intel/intel_fbo.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/mesa/drivers/dri/intel/intel_fbo.c b/src/mesa/drivers/dri/intel/intel_fbo.c index 0b0f0f980b..04723a2f91 100644 --- a/src/mesa/drivers/dri/intel/intel_fbo.c +++ b/src/mesa/drivers/dri/intel/intel_fbo.c @@ -574,9 +574,10 @@ intel_render_texture(GLcontext * ctx, ASSERT(newImage); - if (newImage->Border != 0) { - /* Fallback on drawing to a texture with a border, which won't have a - * miptree. + intel_image = intel_texture_image(newImage); + if (!intel_image->mt) { + /* Fallback on drawing to a texture that doesn't have a miptree + * (has a border, width/height 0, etc.) */ _mesa_reference_renderbuffer(&att->Renderbuffer, NULL); _mesa_render_texture(ctx, fb, att); @@ -607,7 +608,6 @@ intel_render_texture(GLcontext * ctx, irb->Base.RefCount); /* point the renderbufer's region to the texture image region */ - intel_image = intel_texture_image(newImage); if (irb->region != intel_image->mt->region) { if (irb->region) intel_region_release(&irb->region); -- cgit v1.2.3
