Hi,

The main goal of this subtest is to trigger the following warning in
the function i915_gem_object_get_fence():
if (WARN_ON(!obj->map_and_fenceable))
To trigger this warning, the subtest first creates a Y-tiled object and
an associated framebuffer with the Y-fb modifier. Furthermore, to
prevent the map_and_fenceable from being set, we make sure that
the object does not have a normal VMA by refraining from rendering to the
object and by setting the rotation property upfront before calling commit.
v2: Do not call paint_squares and just use one output.
v3: Convert an if condition to igt_require and move the plane rotation
requirement further up before the fb allocation.
