<div>This isn't correct. First off, there are some fairly
strict restrictions on what we can do with tile_x and
tile_y and we can't just shove x/y_offset in there. We
need to use intel_miptree_get_tile_offsets to get both a
byte offset and an intratile offset. Second, we should
already be taking slices into account for cube maps via
base_array_layer where needed.<br>

<div>Unfortunately, I'm not 100% sure what the correct patch
is without a bit more information about what the test is
doing that causes a problem.<br>

I did take a brief look and when running the set mentioned above
(for example with ./deqp-egl
--deqp-case=*EGL.functional.image.create.gles2_cubemap_negative_*_texture)
what happens is that we never end up to the part of code calling
intel_miptree_get_tile_offsets in that function (because
surf.dim_layout != dim_layout condition does not trigger). This is
just what I observed, should we just call
intel_miptree_get_tile_offsets() unconditionally then?<br>
