| /** @file intel_mipmap_tree.h |
| * |
| * This file defines the structure that wraps a BO and describes how the |
| * mipmap levels and slices of a texture are laid out. |
| * |
| * The hardware has a fixed layout of a texture depending on parameters such |
| * as the target/type (2D, 3D, CUBE), width, height, pitch, and number of |
| * mipmap levels. The individual level/layer slices are each 2D rectangles of |
| * pixels at some x/y offset from the start of the drm_intel_bo. |
| * |
| * Original OpenGL allowed texture miplevels to be specified in arbitrary |
| * order, and a texture may change size over time. Thus, each |
| * intel_texture_image has a reference to a miptree that contains the pixel |
| * data sized appropriately for it, which will later be referenced by/copied |
| * to the intel_texture_object at draw time (intel_finalize_mipmap_tree()) so |
| * that there's a single miptree for the complete texture. |
