btw, this fps stuff, as far as I can tell is only for perf/debug traces? In which case, I'd drop this (and 'struct sti_fps_info', etc) and look into adding trace events instead. This would let you log in more detail, correlated to cpu load (and eventual fence traces, and whatever other gpu related traces you feel like adding). That gives a much more detailed view of system performance. I'd done something similar in msm, although not pushed upstream yet:
http://bloggingthemonkey.blogspot.com/2013/09/freedreno-update-moar-fps.html
but when Maarten's fence traces are removed, I should be able to replace most of the msm specific trace events with generic ones (which was only reason I didn't push msm trace events upstream yet).
I would suggest adding the trace events as a follow-up patch, rather than as part of the initial patchset. Or at least I'm not sure offhand if trace events are considered userspace ABI or not, so having it as a follow-up patch avoids delaying the main part of the driver review.
