From eb6418b8952f335b6cf58232b5f282fc3e325c7a Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Sat, 19 May 2007 04:38:55 +0200 Subject: [PATCH] fix miptree layout (i915) for small compressed mipmaps This seems to work now. Also fix i945 set_level_info, need to match i915 behaviour for storing mip height, as it's assumed to be the mip width (in texels) elsewhere and the division by 4 is done later (untested). --- src/mesa/drivers/dri/i915tex/i915_tex_layout.c | 4 +--- src/mesa/drivers/dri/intel/intel_tex_layout.c | 2 +- 2 files changed, 2 insertions(+), 4 deletions(-) diff --git a/src/mesa/drivers/dri/i915tex/i915_tex_layout.c b/src/mesa/drivers/dri/i915tex/i915_tex_layout.c index 2e1600cfdfa..9f40706c36a 100644 --- a/src/mesa/drivers/dri/i915tex/i915_tex_layout.c +++ b/src/mesa/drivers/dri/i915tex/i915_tex_layout.c @@ -161,11 +161,9 @@ i915_miptree_layout(struct intel_mipmap_tree * mt) if (mt->compressed) img_height = MAX2(1, height / 4); else - img_height = MAX2(2, height); + img_height = (MAX2(2, height) + 1) & ~1; mt->total_height += img_height; - mt->total_height += 1; - mt->total_height &= ~1; width = minify(width); height = minify(height); diff --git a/src/mesa/drivers/dri/intel/intel_tex_layout.c b/src/mesa/drivers/dri/intel/intel_tex_layout.c index f3564802171..fcb5cc39068 100644 --- a/src/mesa/drivers/dri/intel/intel_tex_layout.c +++ b/src/mesa/drivers/dri/intel/intel_tex_layout.c @@ -74,7 +74,7 @@ void i945_miptree_layout_2d( struct intel_mipmap_tree *mt ) GLuint img_height; intel_miptree_set_level_info(mt, level, 1, x, y, width, - mt->compressed ? height/4 : height, 1); + height, 1); if (mt->compressed) img_height = MAX2(1, height/4); -- 2.30.2
