Author: Eric Anholt <[email protected]> Date: Thu Jun 9 17:04:12 2011 -0700 intel: Fix miptree height alignment for compressed NPOT textures. This is effectively just "round up when dividing by 4" compared to the previous code. Fixes the broken stripe at the top of fbo-generatemipmap-formats GL_EXT_texture_compression_rgtc. --- src/mesa/drivers/dri/intel/intel_tex_layout.c | 6 ++---- 1 files changed, 2 insertions(+), 4 deletions(-) diff --git a/src/mesa/drivers/dri/intel/intel_tex_layout.c b/src/mesa/drivers/dri/intel/intel_tex_layout.c index 91ee55e..9d81523 100644 --- a/src/mesa/drivers/dri/intel/intel_tex_layout.c +++ b/src/mesa/drivers/dri/intel/intel_tex_layout.c @@ -97,11 +97,9 @@ void i945_miptree_layout_2d(struct intel_context *intel, intel_miptree_set_level_info(mt, level, nr_images, x, y, width, height, 1); + img_height = ALIGN(height, align_h); if (mt->compressed) - img_height = MAX2(1, height/4); - else - img_height = ALIGN(height, align_h); - + img_height /= align_h; /* Because the images are packed better, the final offset * might not be the maximal one: _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
