From: Brian Paul Date: Mon, 12 Oct 2009 23:37:06 +0000 (-0600) Subject: intel: pass zslice to intel_miptree_image_offset() X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e6594a22f298833eeb6881795b24d03d2fd8e898;p=mesa.git intel: pass zslice to intel_miptree_image_offset() This lets us get rid of intel_miptree_depth_offsets() and simplify all of the calling code. --- diff --git a/src/mesa/drivers/dri/i915/i830_texstate.c b/src/mesa/drivers/dri/i915/i830_texstate.c index 6f998fa6f77..f270a137812 100644 --- a/src/mesa/drivers/dri/i915/i830_texstate.c +++ b/src/mesa/drivers/dri/i915/i830_texstate.c @@ -162,9 +162,8 @@ i830_update_tex_unit(struct intel_context *intel, GLuint unit, GLuint ss3) } else { dri_bo_reference(intelObj->mt->region->buffer);
