Oh well, I wrote my comments below and then read this link. Please add
new test requirements in separate patches. Only have the code movement
here.

This check used to be igt_require(gen >= 10

There was also a check for tiling format 
-                                   (IS_CHERRYVIEW(data.devid) &&
reflect_x->rot == IGT_ROTATION_0
-                                    && reflect_x->tiling ==
LOCAL_I915_FORMAT_MOD_X_TILED));

Doesn't look like this requirement was is in the test earlier.

Why do this?
