From: Michel Dänzer Date: Thu, 14 Dec 2006 11:32:41 +0000 (+0100) Subject: Share code to lay out >= 945 style 2D mipmaps between i915tex and i965 drivers. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3416ef303af633668cece0b199b4a8b2388c1e2f;p=mesa.git 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. --- diff --git a/src/mesa/drivers/dri/i915tex/Makefile b/src/mesa/drivers/dri/i915tex/Makefile index 94879d209f7..3b3f3f5a3f7 100644 --- a/src/mesa/drivers/dri/i915tex/Makefile +++ b/src/mesa/drivers/dri/i915tex/Makefile @@ -20,6 +20,7 @@ DRIVER_SOURCES = \ intel_batchbuffer.c \ intel_mipmap_tree.c \ i915_tex_layout.c \ + intel_tex_layout.c \ intel_tex_image.c \ intel_tex_subimage.c \ intel_tex_copy.c \ @@ -59,8 +60,10 @@ C_SOURCES = \ ASM_SOURCES = - +DRIVER_DEFINES = -I../intel include ../Makefile.template +intel_tex_layout.o: ../intel/intel_tex_layout.c + symlinks: diff --git a/src/mesa/drivers/dri/i915tex/i915_tex_layout.c b/src/mesa/drivers/dri/i915tex/i915_tex_layout.c index e9360ecea83..fc98611d319 100644 --- a/src/mesa/drivers/dri/i915tex/i915_tex_layout.c +++ b/src/mesa/drivers/dri/i915tex/i915_tex_layout.c @@ -30,6 +30,7 @@ */ #include "intel_mipmap_tree.h" +#include "intel_tex_layout.h" #include "macros.h" #include "intel_context.h" @@ -52,12 +53,6 @@ static GLint step_offsets[6][2] = { {0, 2}, {-1, 1} }; -static GLuint -minify(GLuint d) -{ - return MAX2(1, d >> 1); -} - GLboolean i915_miptree_layout(struct intel_mipmap_tree * mt) { @@ -322,52 +317,9 @@ i945_miptree_layout(struct intel_mipmap_tree * mt) case GL_TEXTURE_1D: case GL_TEXTURE_2D: - case GL_TEXTURE_RECTANGLE_ARB:{ - GLuint x = 0; - GLuint y = 0; - GLuint width = mt->width0; - GLuint height = mt->height0; - GLint align_h = 2; - - 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 ?
