This gets rid of all the interactions between the legacy flip code and the modeset code. Yay!
Including our missed vblank boosting. (That's been dead for a while.)
Hm right, but should be easy to add (and bonus, for every display update, not just flips) in the intel_sw_fence_wait function. Can you pls point me at what function I should call to reverse-boost an i915_sw_fence (and only that)?
Then we could queue up a vblank callback that fires on the next vblank for any of the CRTC in the update and boosts the i915_sw_fence. If we just boost the fence (instead of the context or something) it should also be easy to filter out boosting when the request has completed meanwhile. -Daniel
