+   * Tiled monitors may look a bit different from each other, depending on the

+   *
+   * On some, the tiled modes will be the preferred CRTC modes, and running
+   * untiled is done by only enabling (0, 0) tile. In this case, things are
+   * pretty straight forward.
+   *
+   * Other times a monitor may have some bogus mode preferred on the main tile,
+   * and an untiled mode preferred on the non-main tile, and there seems to be
+   * no guarantee that the (0, 0) tile is the one that should drive the
+   * non-tiled mode.
+   *
+   * To handle both these cases, the following hueristics are implemented:
+   *
+   *  1) Find all the tiled CRTC modes of the (0, 0) tile, and create tiled
+   *     monitor modes for all tiles based on these.
+   *  2) If there is any tiled monitor mode combination where all CRTC modes
+   *     are the preferred ones, that one is marked as preferred.
+   *  3) If there is no preferred mode determined so far, assume the tiled
+   *     monitor mode with the highest refresh rate is preferred.
+   *  4) Find the tile with highest number of untiled CRTC modes available,
+   *     assume this is the one driving the monitor in untiled mode, and
+   *     create monitor modes for all untiled CRTC modes of that tile. If
+   *     there is still no preferred mode, set any untiled mode as preferred
+   *     if the CRTC mode is marked as such.
+   *  5) If at this point there is still no preferred mode, just pick the one
+   *     with the highest number of pixels and highest refresh rate.
+   *
+   * Note that this ignores the preference if the preference is a non-tiled
+   * mode. This seems to be the case on some systems, where the user tends to
+   * manually set up the tiled mode anyway.
