I received an answer on the intel-gfx mailing list: http://lists.freedesktop.org/archives/intel-gfx/2014-November/055165.html

Right now some of the more advanced features require a bit of tweaking but not so much that any black magic is required. - Nate -- "The optimist proclaims that we live in the best of all possible worlds.
