From 51ce86b7811871896d3b838888ab4adbfb77413d Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 8 Jun 2011 16:38:01 -0700 Subject: [PATCH] intel: Fix 2x2 and 1x1 compressed teximages from _mesa_generate_mipmap() Generally image uploads to a the region occur at TexImage time, but that's not the case for fallback _mesa_generate_mipmap(), and in this path we were forgetting to align the width when dividing height. We were just leaving out parts of the compressed block at 2x2 and 1x1 levels. Fixes gen-compressed-teximage. --- src/mesa/drivers/dri/intel/intel_mipmap_tree.c | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) diff --git a/src/mesa/drivers/dri/intel/intel_mipmap_tree.c b/src/mesa/drivers/dri/intel/intel_mipmap_tree.c index e62905d..55eb9a1 100644 --- a/src/mesa/drivers/dri/intel/intel_mipmap_tree.c +++ b/src/mesa/drivers/dri/intel/intel_mipmap_tree.c @@ -389,26 +389,33 @@ intel_miptree_image_data(struct intel_context *intel, GLuint i; for (i = 0; i < depth; i++) { - GLuint dst_x, dst_y, height; + GLuint dst_x, dst_y, height, width; intel_miptree_get_image_offset(dst, level, face, i, &dst_x, &dst_y); height = dst->level[level].height; - if(dst->compressed) - height = (height + 3) / 4; + width = dst->level[level].width; + if (dst->compressed) { + unsigned int align_w, align_h; + + intel_get_texture_alignment_unit(dst->internal_format, + &align_w, &align_h); + height = (height + align_h - 1) / align_h; + width = ALIGN(width, align_w); + } DBG("%s: %d/%d %p/%d -> (%d, %d)/%d (%d, %d)\n", __FUNCTION__, face, level, src, src_row_pitch * dst->cpp, dst_x, dst_y, dst->region->pitch * dst->cpp, - dst->level[level].width, height); + width, height); intel_region_data(intel, dst->region, 0, dst_x, dst_y, src, src_row_pitch, 0, 0, /* source x, y */ - dst->level[level].width, height); /* width, height */ + width, height); src = (char *)src + src_image_pitch * dst->cpp; } -- 2.7.4
