fbc and psr are independend features and tasks prioritization should come from managers and program managers, right?!
And then I also want fbc enabled by default, which means you need to
rebase/review Ville's patch series to make that work.
We have FBC working with issues and protected by parameter on all platforms. On BDW there is no fbc at all. This patch makes FBC state at least go to the same level as we already have FBC working on all other platforms.
I don't see a dependency here between this fix and the big FBC rework-fix. This patch isn't enabling FBC by default. But allowing people that want and need to use FBC.
Also I really think the fb frontbuffer tracking can be made to work
for fbc - if you do it right you should actually end up with fewer
frontbuffer flushes than what we currently do by submitting them
through rings.
