<pre>Hi,
With following patches FB changes with flip is captured and DRRS is notified
accordingly.
<a href="http://www.spinics.net/lists/intel-gfx/msg68515.html">http://www.spinics.net/lists/intel-gfx/msg68515.html</a>
<a href="http://www.spinics.net/lists/intel-gfx/msg68516.html">http://www.spinics.net/lists/intel-gfx/msg68516.html</a>
But if the FB change carried out without flip, then we dont get the fb change
notification.
Might be in few places in intel_gem.c fb_obj_invalidate call is missed. Else
the obj->frontbuffer_bits are not set while calling the fb_obj_invalidate.
Gem expert's eye on this will be fruitful.</pre>
