From 3416ef303af633668cece0b199b4a8b2388c1e2f Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Thu, 14 Dec 2006 12:32:41 +0100 Subject: Share code to lay out >= 945 style 2D mipmaps between i915tex and i965 drivers. Use the i965 version as it has some fixes over the i915tex version. --- src/mesa/drivers/dri/i965/brw_tex_layout.c | 55 ++---------------------------- 1 file changed, 3 insertions(+), 52 deletions(-) (limited to 'src/mesa/drivers/dri/i965/brw_tex_layout.c') diff --git a/src/mesa/drivers/dri/i965/brw_tex_layout.c b/src/mesa/drivers/dri/i965/brw_tex_layout.c index 1353325aff..af1ad0f1ef 100644 --- a/src/mesa/drivers/dri/i965/brw_tex_layout.c +++ b/src/mesa/drivers/dri/i965/brw_tex_layout.c @@ -34,21 +34,15 @@ */ #include "intel_mipmap_tree.h" +#include "intel_tex_layout.h" #include "macros.h" -static GLuint minify( GLuint d ) -{ - return MAX2(1, d>>1); -} - GLboolean brw_miptree_layout( struct intel_mipmap_tree *mt ) { /* XXX: these vary depending on image format: */ /* GLint align_w = 4; */ - GLint align_h = 2; - switch (mt->target) { case GL_TEXTURE_CUBE_MAP: @@ -107,53 +101,10 @@ GLboolean brw_miptree_layout( struct intel_mipmap_tree *mt ) break; } - default: { - GLuint level; - GLuint x = 0; - GLuint y = 0; - GLuint width = mt->width0; - GLuint height = mt->height0; - - mt->pitch = ((mt->width0 * mt->cpp + 3) & ~3) / mt->cpp; - mt->total_height = 0; - - for ( level = mt->first_level ; level <= mt->last_level ; level++ ) { - GLuint img_height; - - intel_miptree_set_level_info(mt, level, 1, - x, y, - width, - mt->compressed ? height/4 : height, 1); - - if (mt->compressed) - img_height = MAX2(1, height/4); - else - img_height = MAX2(align_h, height); - - - /* Because the images are packed better, the final offset - * might not be the maximal one: - */ - mt->total_height = MAX2(mt->total_height, y + img_height); - - /* Layout_below: step right after second mipmap. - */ - if (level == mt->first_level + 1) { - x += mt->pitch / 2; - x = (x + 3) & ~ 3; - } - else { - y += img_height; - y += align_h - 1; - y &= ~(align_h - 1); - } - - width = minify(width); - height = minify(height); - } + default: + i945_miptree_layout_2d(mt); break; } - } DBG("%s: %dx%dx%d - sz 0x%x\n", __FUNCTION__, mt->pitch, mt->total_height, -- cgit v1.2.3
